Presbyopia is the gradual loss of your eyes’ ability to focus on near objects. It is a natural, age related process that usually becomes noticeable in your early to mid-40s and continues to increase until around age 65 or 70 years of age.
You may become aware of this condition when you start holding books and newspapers at an arm’s length to be able to read them. If you are nearsighted (myopic), you might temporarily manage to continue reading if you read without using your distant glasses.
A routine eye consultation can confirm this diagnosis.
You can correct the condition with nonprescription reading glasses or prescription eyeglasses or contact lenses. Surgery also may be an option for presbyopia.
About Presbyopia and LASIK
After 40 years, we all need to use reading glasses. In older people who have not had LASIK done and still need to use numbers for distant work, these are then used as ‘Bi focals’ or ‘verifocals’. Reading glasses are an age related issue and no one is exempt from it.
There is no permanent treatment by laser for this, although some doctors advertise ‘presbyopic LASIK’, which is a laser treatment needing to be repeated every 1 or 1.5 years and is still in its infancy, hence not advocated by Dr Anand Shroff, our LASIK expert and Corneal surgeon.
Correcting Presbyopia with Intra ocular lens implant surgery
There is one way to avoid reading numbers and also correct myopia (minus numbers for distance), which is by a surgery using implants or accomodative (wavefront lenses), which may be a good option for older age groups.
In accomodative or multifocal implants, the natural lens of your eye is replaced, and hence there is no chance of any cataract in the future.
This surgery is also called PRELEX, which can be performed in some cases for presbyopia.
PRELEX stands for PREsbyopic Lens EXchange. It involves removing your old, inflexible natural lens and replacing it with an artificial one. The operation is performed under local anaesthetic, so you are kept awake but the eye is numbed. (ZThis is similar to the Artificial lenses which are quite often put in after cataract surgery, only the lenses used are more advanced helping you see in all focuses.)
It is only a detailed eye examination + understanding what kind of work you do (whether more distant related or computers etc, whether you drive a lot at night etc), that we help you make an nformed decision regarding the most suitable treatment for you.
Ans. This can be best answered after your eye examination with Dr Shroff. But yes, those in the older age group, usually in their 50′s are advised a lens implant procedure as it is more likely that they are closer … Continue reading →
Common questions on laser eye procedures which are asked by most patients around the world. Will laser eye surgery fix or cure astigmatism? Yes, however to a certain limit depending also on the shape of your cornea. Astigmatism means powers … Continue reading →
Do powers or numbers come back after LASIK surgery? How can we prevent this and what can be done if they do come back?
Let us say that you had LASIK surgery and achieved 6/6 or 20/20 vision, then many patients want to know how long does this result last? And are there any chances that their spectacle powers would regress?
LASIK surgery is a permanent treatment. What change it creates in the shape of the cornea is permanent.
However, the way you use your eyes is a dynamic process. Even if the LASIK was successful and you achieved 6/6 post procedure, to remain 20/20 there are certain basic guidelines that one must follow.
Remember that LASIK was done to achieve clear distant vision. If you end up doing a lot of near work, especially continuous hours of computer related work, then you stand the risk of again changing your distant prescription which is zero after LASIK and can shift by a small power of -0.50 D to -1.00 D if you end up straining your eyes for near work. Hence, in our centre at Shroff Eye, Dr Anand Shroff, our LASIK surgeon examines your eyes personally for a LASIK treatment and advises how you can avoid getting this regression, which may include specific steps of how to sit in front of a computer screen and use computer anti fatigue glasses specific to your viewing distance. This is taught to you post LASIK, at our centre.
However, other than the most common reason for shift of powers, which is computers, there are other factors which also play a role in eye health. Vision can deteriorate if any other event happens inside the eyes, example the start of a cataract or retinal issue or need for reading glasses (presbyopia) which is a natural aging process in the eyes. Although this is totally unrelated to LASIK, and would have happened with the same possibility when you use glasses or contact lenses, many link it to a LASIK done many years ago. This is not true. The start of any internal eye disease is not linked to your LASIK.
In women, it is also important to mention the use of hormones for treating acne or even infertility etc. In such times, hormones in very rare cases may also cause a shift in myopia.
In those with very high myopia or high astigmatism or cylindrical powers, we prepare them with the small possibility of needing a fine tuning or retreatment procedure, also called enhancement. This is usually done not before 3 months of the LASIK, giving enough time for the corneal healing to be complete. Also, this re treatment does not mean repeating all steps done the first time, but in most cases just needs specific instruments to lift the previously prepared flap and a very short laser application to remove the power. In those where the flap lifting is doubtful, a PRK procedure can be done as a surface treatment.
Therefore, it is important to choose a primary LASIK treatment with an advanced laser, such as what we use at Shroff Eye, the 500 Hz Wavelight laser that helps score over others as it has corneal tissue saving capacity. Hence it is possible to retreat whenever required.
In many cases, people who experience minor number changes after LASIK are not bothered by the small power and do not feel the need for wearing glasses, except for specific tasks like night driving, where it is used more for safety. Some choose to undergo a retreatment whenever possible, for example the rate of re treatment in our LASIK centre with Dr Anand Shroff is less than 0.4% of our cases and most often the fee is not charged again.
As the person`s age increases, ability of the eye to focus on nearby objects decreases. This being age related process, is irreversible and called Presbyopia. Hence everyone above 40 years will need reading glasses even after the laser procedure. But … Continue reading →
Surgical options are increasing for higher levels of nearsightedness.
By Elizabeth Yeu, MD
Myopia is the most common refractive error — in the United States alone, it affects between 25% to 41% of the population. While myopia vastly differs amongst various ethnicities, it appears there may be truth to our parents’ incessant nagging during childhood to not sit too close to the television, as excessive near-point work appears to be strongly correlated with myopia progression. Other contributing factors include genetic predilection, prolonged dark exposure, education level and an inverse relationship to the amount of time spent outdoors.
While excellent surgical options exist for the treatment of low (3.00 D or less of myopic spherical equivalent error) to moderate (3.25 D to 6.00 D) myopia, the treatment of high myopia remains one of the greater challenges refractive surgeons face today. Corneal excimer laser surgery (LASIK, advanced surface ablation), refractive lens exchange (RLE) and phakic lens technology / ICL are the options I will address here.
EXCIMER ABLATION AND ITS VARIANTS
Popular, but not without risks
Corneal excimer laser surgery — LASIK and advanced surface ablation techniques including PRK, LASEK and Epi-LASIK — is undoubtedly the most popular refractive surgical procedure performed in the pre-cataract population. It can accurately treat myopic refractive errors up to 12.00 D.
However, potential problems can crop up. Corneal ectasia and its prevention is a top concern for refractive surgeons at all times. Postrefractive surgery ectasia — progressive corneal steepening and thinning, combined with progressive myopic astigmatism — is associated with various risk factors, including irregular corneal topography, age, higher myopia, thinner central corneal thickness and low residual stromal bed (Figure 1).
Figure 1: Corneal topography from two patients with post-LASIK ectasia. They demonstrate different severities of inferior steepening on the anterior float and very elevated posterior floats.
Surgeons have various methods to help them better assess a patient’s risk for developing ectasia, including advanced imaging technology and device software to review posterior corneal curvature and other global screening modalities, such as the Randleman Ectasia Risk Scoring System.
While no single modality is foolproof in identifying potentially ectasic patients, the Randleman Risk Scoring System draws attention to the most disconcerting features in those at highest risk. Ultimately, corneas that develop postsurgical ectasias likely have an abnormal hysteresis as an underlying etiology, so a way to accurately measure this will be instrumental.
LASIK and advanced surface ablation
LASIK for high-risk corneas will likely gain more traction as we become more familiar with collagen cross linking (CXL). In the setting of post-LASIK or PRK ectasia, CXL is extremely effective at stabilizing the cornea, as well as bringing about a progressive flattening effect over time. It will be interesting to see how clinicians use CXL in conjunction with LASIK in naïve corneas, as this will require adjustments to surgical treatment plans and require nomograms to account for the flattening effect that CXL itself induces.
LASIK is not always a viable option for high myopes, of course, because they may have inadequate residual stromal bed or dry eye disease. In these cases, advanced surface ablation (PRK, LASEK or Epi-LASIK) may be a good alternative.
Managing outcomes postoperatively
Unfortunately, stromal haze is more commonly associated with higher ablation depths. The surgeon applies mitomycin C 0.02% for 12 seconds after the laser ablation to effectively mitigate corneal haze for eyes at greatest risk, including those with ablations greater or equal to 6.00 D or greater than 75 μm.
Other measures to prevent haze are somewhat anecdotal, but an extended course of oral vitamin C, oral steroids and a four-month tapering of steroids postoperatively may also prevent haze formation. More importantly, given the relationship between UV exposure and corneal haze, even one to two years after surgery, ophthalmologists should emphasize protection from and limited exposure to UV radiation. Other important considerations unique to advanced surface ablation can be drawbacks in the immediate postoperative period. In my experience, the recovery of the final visual acuity for higher myopic ablations is more protracted, and can take upwards of two to three months to achieve stability.
Pain is another immediate side effect;, which may or may not differ between the techniques for surface ablation. However, no correlation appears to exist between the degree of discomfort and depth of treatment.
REFRACTIVE LENS EXCHANGE
Age as a determining factor
Refractive lens exchange is an effective surgical alternative when corneal laser refractive surgery may not be, such as for myopia greater than 10.00 D, irregular or higher levels of astigmatism, thin corneas or the patient’s desire for presbyopia correction. RLE is often the treatment of choice for hyperopic presbyopes age 40 years and older. However, RLE is less commonly recommended for younger (age 50 years and younger) or highly myopic patients, or both. The key reasons are:
Although infrequent, RLE is associated with an increased risk of retinal detachments (RD), which occur with a reported incidence of less than 2% to 8.5%.Of note, the highest risk of RD may correlate to an intact vitreous, as one study demonstrating the highest incidence of RD also had a low incidence of PVD (16%) in a group of RLE patients.
Performing RLE in younger, prepresbyopic patients can lead to dissatisfaction from the drastic loss of accommodation.
RLE for children?
One instance in which RLE is a successful, clinically indicated treatment of choice for a young patient would be for highly myopic children. More specifically, RLE should be considered in children who have amblyopia from their extreme myopia, refuse to conform to spectacle or contact lens wear or both, have neurobehavioral disorders, and their myopia is beyond the range for what we can treat with laser surface ablation or phakic IOL implantation.
Others for RLE
Additionally, certain patients with a primary corneal ectasia, such as keratoconus, may be surgically treated with RLE. The treatment of irregular astigmatism is an off-label use of toric IOLs, but it can be an effective option in patients who have excellent spectacle-corrected visual potential.
RLE is not indicated in patients who have poor spectacle-corrected vision. When evaluating these patients, it is imperative to have agreement amongst several devices for the amount and location of the steep meridian.
RLE is my go-to recommendation for hyperopes age 50 years or older and for moderate-to-moderately high myopes with incipient cataracts or closer to age 60 years, especially if they have a posterior vitreous detachment. Some of my happiest RLE patients are the contact lens-intolerant, higher myopes with astigmatism greater than 2.00 D.
Although RLE is an off-label use in these patients, they include those with irregular astigmatism, such as that seen in keratoconus, but only for those who have had very good-to-excellent spectacle-corrected vision and with astigmatism and steep meridian measures consistent amongst various devices.
A fix for presbyopes, too
RLE is also the obvious option for my older patients who desire presbyopia correction but have not been successful with monovision. For concomitant presbyopia correction, I opt for monovision RLE in those patients who were successful monovision contact lens wearers. I use the Tecnis multifocal (MTF) IOL (Abbott Medical Optics, Abbott Park, Ill.) over other presbyopic IOLs, but I’ve also had great success utilizing the Tecnis MTF in the dominant eye and the Crystalens AO IOL (Bausch + Lomb, Rochester, N.Y.) in the non-dominant eye to maximize the benefits of both IOLs while mitigating the scotopic visual aberrations around lights inherent to any multifocal IOL.
In my younger patients who have yet to experience any natural yellowing of their lens, I prefer a chromophore-free IOL.
LASIK for high-risk corneas will likely gain more traction as more corneal surgeons embrace collagen cross linking.

Spot-on calculations are crucial
When planning surgery for RLE patients, accurate IOL calculations are imperative. For unclear reasons, certain modern IOL formulas tend to result in postoperative hyperopia, which may result from a more posterior effective lens position or a different index of refraction through a very liquefied vitreous cavity.
Regardless of the cause, using different tools such as an intraoperative aberrometer or an optimized axial length (AL) formula — such as optimized AL >25.0= 0.883(AL) + 2.825 — can help achieve more accurate postoperative results.
PHAKIC IOLS / ICL
Phakic IOLs (PIOLs) represent another excellent surgical treatment option for myopia from 3.00 D to 20.00 D. Although several different phakic IOLs are available worldwide, including those with toric correction, in the United States we have only two FDA-approved phakic IOLs to treat myopia alone: the Verisyse iris-enclavated phakic IOL (AMO) and the sulcus-supported STAAR Visian ICL (implantable collamer lens) (STAAR Surgical, Monrovia, Calif.).
PIOLs offer several advantages, including reversibility, lower retinal detachment rate than RLE and preservation of accommodation.17 In comparison to corneal excimer laser surgery for treating high myopia, patient satisfaction may be higher with PIOLs.18 This could be partially attributed to the lower ocular higher-order aberrations and better contrast sensitivity that occurs with PIOL implantation than corneal excimer laser surgery.19
Choose the right patient
Phakic IOLs are a great option for myopes between -5.00 D to -20.00 D younger than age 40 years without cataract but with mild-to-moderate astigmatism. Additionally, PIOLs give us something for patients for whom LASIK and PRK are not appropriate.
In United States, PIOLs are not suitable for myopia exceeding 20.00 D, nor is a toric option available. Further, depending on the PIOL, they may be contraindicated for patients with Fuchs’ dystrophy or pigment dispersion.
Potential drawbacks of PIOLS
The most concerning long-term safety issues for PIOLs include endothelial cell loss and cataract formation. The incidence of such complications vary between studies and are likely to be higher in a surgeon’s early experience with PIOLs.
Secondary glaucoma (pupillary block, pigment dispersion), chronic inflammation, iris atrophy (pupil ovalization) and traumatic dislocation are also potential long-term risks that have been associated with PIOLs.
Other hurdles with PIOL technology include the accuracy of the lens calculation because the angle width and sulcus diameter correlate poorly with the white-to-white diameter. The result is that more expensive technology is required to measure directly, such as a high-frequency ultrasound or anterior segment OCT. Lastly, long-term data greater than five to six years is lacking for this relatively newer technology.
In the United States, PIOL technology is limited to myopia correction alone. For the time being, other patients can be treated with a combination of options, such as relaxing incisions or corneal excimer laser enhancement to correct residual refractive errors. Similarly, post-RLE patients may also benefit from a corneal refractive procedure as an enhancement.
Better distance vision is in sight
Although high levels of myopia are still difficult to treat, options are on the horizon. Ongoing studies are evaluating everything from collagen cross-linking to angle-supported PIOLs. When these modalities accumulate more long-term data and win FDA approval, we will enjoy greatly enhanced ability to treat certain patient groups, such as the myopic or astigmatic presbyope, more effectively.
With myopia so prevalent in the United States, both surgeons and their very nearsighted patients will welcome these advances warmly.
Even if you undergo LASIK and achieve perfect distant vision, you will still develop a condition called presbyopia, typically beginning between the ages of 40 and 50, where the near vision gets affected. This is due to aging. When this situation arises, you will need reading glasses to get near objects into focus.
Presbyopia is usually noticed when fine print starts to blur.
In the past and even today, the usual remedy is to wear reading glasses or special multifocal lenses (bifocal or progressive lenses) for presbyopia. But there are other options and surgical remedies for presbyopia for some candidates. One of them is performing Monovision LASIK.
What is Monovision?
Monovision refers to the vision correction practice of prescribing distance vision in one eye and near vision in the other eye. This situation is usually created by applying contact lenses to the eyes or performing LASIK or refractive eye surgery. One of the first effective surgical options for presbyopia correction involved producing what is known as “monovision” during LASIK.
How does monovision work?
Normally, both your eyes work together equally when you look at an object, to produce what’s called binocular vision.
However, you probably have a dominant eye that your brain tends to favour such as how we are either right-handed or left- handed).
Taking advantage of this “one-eye dominance” to produce monovision, where typically the dominant eye is prescribed a contact lens power for optimum distance vision and the other eye is fit with a contact lens that has a modified power to provide good near vision.
But one eye sees more clearly in the distance, and the other eye sees better up close. This is a very helpful technique for patients who are over 40 who need reading glasses and also need help for distance vision.
Who are good candidates for monovision?
The age and near addition of the patient matter, with lower addition patients (+1.25 to +2.00 D) being more successful than higher addition, more advanced presbyopic patients.
The visual needs and lifestyle of the patient must be evaluated when considering monovision. Individuals in occupations such as teaching, the performing arts, public speaking and sales, who desire the benefit of being able to change viewing distances constantly and still remain
focused, are good candidates.
Some LASIK surgeons will produce monovision in their presbyopic patients by purposely leaving the non-dominant eye slightly nearsighted so that these patients can see up close without glasses. This usually takes some getting used to, and there are certain situations where it would not be appropriate. However we need to evaluate the patient thoroughly as not everyone can become accustomed to monovision.
When surgery is performed, the desired outcome is typically the same as that for monovision contact lens correction; however, it should be remembered that the patient’s need for additional near correction is likely to change again with age.
Hence, we always recommend that is a good idea to try monovision with contact lenses or trial lenses first to be sure you can adapt to it before you opt for monovision LASIK.
Primeval man was a hunter, farmer and a warrior. Nature had designed his eyes mainly for these tasks related to distant vision, such that during these tasks the eyes were at rest. Sight was supposed to be a passive action requiring no muscular action whatsoever. Near vision needed muscular adjustment of very short duration which did not place any considerable burden on this mechanism of accommodation. However, this environment was long-ago.
Today, as a human race, we have moved forward at a tremendous pace with revolutions in areas of industry and agriculture. This rapid industrialisation came with changes in our lifestyle and work environment. And with that came the strains and stresses of modern times.
In the present day there is a lot of health awareness amongst the masses. Fitness of the body as a whole is well taken care of but this does not extend to taking care of our vision. Our eyes are in continuous use from the minute we wake up till the time we sleep. The way we utilize them will affect how well we can work all through our lifetime. Learning depends tremendously on vision, as over eighty percent is arbitrated through our eyes. Sight is our most precious sense, still most of us take our eyes for granted, never thinking of them as organs needing any kind of care until the time we face some visual disturbances.
The eye muscles include an internal eye muscle- the ciliary muscle that surrounds the lens and six muscles attached to the outside of the eye. All these muscles have to work in sync by alignment, balance and coordination in such ways that is required to change focus of vision rapidly, track speedy moving objects, create depth perception and focus clearly for both far and near.
In modern times, with prolonged working hours, the eyes have more difficulty focusing for prolonged periods of time without blurring or softening the focus. This is particularly noticeable when you shift your focus from an object that is close-up to one that is in the distance.
In today’s internet and computer driven world, headaches, focusing difficulties, burning eyes, tired eyes, eyestrain, aching eyes, dry eyes, double vision, blurred vision, light sensitivity, and neck and shoulder pain are often caused by eyestrain from working for long periods. Near point stress is one of the most common job related symptoms of eyestrain.
Since long, people believe that poor eyesight can be treated by special eye exercises. This belief was popularized by Dr William Horatio Bates with “Bates’ eye exercises’.
These exercises do not influence visual disorders of nearsightedness, farsightedness, astigmatism, and presbyopia as these visual problems result from natural and acquired characteristics of the lens and the eyeball and no exercise can change that.
There are scientifically-proven exercises for specific eye disorders and misalignments of the eyes which are called ‘Orthoptics’. This is a form of vision therapy which may help people with focus problems including conversion insufficiency, double vision, strabismus and amblyopia (lazy eye).
So, what can one do for normal eyes?
By adopting good eye care habits, we can prevent many of the symptoms of eye fatigue.
1) Do not read closely.
2) Make sure that you work in a well lit environment
3) Take frequent breaks – Relax your eyes.
4) Shift focus from near objects to distant objects.
Eyes are considered to be the mirrors of your soul and taking care of them is of utmost importance. Eye care should be an important part of our daily life. The eye is an extremely delicate organ and any damage may result in permanent loss of sight.
Vision problems can present with a variety of symptoms ranging from simple irritation of the eye to decrease/loss of vision. This may be very uncomfortable and at times disturbing for the patient. Common symptoms include –
Simple refractive error in which light is focused at a spot other than the back of the retina is the most common cause. Myopia (near sightedness), hyperopia (far sightedness) and astigmatism lie within this category of vision problems. The most prevalent treatment methods involve prescription eyewear such as glasses and contact lenses, but LASIK surgery is becoming an ever more popular and effective long-term solution.

Do check your suitability for Laser Eye Surgery or LASIK as latest technology customizes the treatments for your needs, numbers and age.
The most common symptom of cataract is cloudy vision, wherein the visual image becomes obscured as if seen through a mist. This condition is a result of loss of transparency of the lens with age. Cataract removal is possible in almost all cases via surgery, so it is important for patients’ experiencing this problem to contact an eye doctor as soon as possible.
Shroff Eye Opener # 33
DO NOT wait for your cataract to mature. Visit your eye doctor in the early stage of cataract, as new advanced treatment will work better. Loss of Peripheral Vision
Vision can be divided into 2 domains – central and peripheral.
While discerning the small details of an object’s appearance requires us to focus on it with the central part of our vision, our peripheral vision helps us detect motion at the edges of our field of view. Glaucoma is one of the common conditions, which causes deterioration of the quality of peripheral vision. Glaucoma treatment options are usually effective, but much more so if the disease is caught early.
Shroff Eye Opener # 35
DO check your eyes with an eye doctor. Without proper treatment, glaucoma in the eyes can lead to irreversible blindness. Itchy, Watery Eyes
Prolonged itchiness and watering of the eyes is among the more common vision problems. These are due to some type of eye allergies to pollen, pet hair, or to some other foreign substance in the environment. The eyes often become red and very uncomfortable, though significant vision loss is rare.
Shroff Eye Opener # 54
Don’t splash water inside your eyes, as is a habit for some people. This washes away the tear film that is a protective layer and can cause ‘dry eyes’ in the long run. Floaters and Flashes
Dark, distinct spots in the vision field caused by the presence of non-transparent substances in the fluid of the eyeball are called floaters. People who see flashes often describe them as being like an arc of light across the field of vision, or a light bulb going on and off. Floaters and flashes are among the symptoms that arise after retinal detachment, in which the retina peels away from its underlying supports and ceases to function properly. This condition is an emergency and can lead to permanent blindness if not treated immediately.
Shroff Eye Opener # 34
DO check your eyes regularly if you have Diabetes. Diabetes is a leading cause of blindness and its early detection and treatment can greatly decrease the risk
Shroff Eye Openers TM – DO’s and DON’Ts
While not all eye diseases can be prevented, there are simple steps that everyone can take to help their eyes remain healthy now and reduce their chances of vision loss in the future.
During the Summer –
Wear sunglasses – UV blocking sunglasses delay the development of cataracts, since direct sunlight hastens their formation. Sunglasses prevent retinal damage; they also protect the delicate eyelid skin to prevent both wrinkles and skin cancer around the eye. Make sure your sunglasses block 100 percent of UV rays and UV-B rays.
Shroff Eye Opener # 50.
Don’t step outdoors in the summer without Ultraviolet absorbing eyewear.
Shroff Eye Opener #51.
Don’t presume that the darker the tint of your sunglasses the more UV protection you have. If not really UV protected, such eyewear will cause more damage.
Shroff Eye Opener # 61.
Lower your computer screen so that the centre of the screen is 4-8 inches below your eye level and at a viewing distance of 20-28 inches.
Shroff Eye Opener #62.
Use a document holder placed next to your computer screen. It should be close enough so you don’t have to swing your head back and forth or constantly change your eye focus.
Shroff Eye Opener #66.
Concentrate on blinking whenever you begin to sense symptoms of dry or irritated eyes.
Shroff Eye Opener #67.
Take frequent breaks when on the computer. Follow the 20-20-20 rule. This simply means every 20 minutes, look away beyond 20 feet and blink 20 times. This will prevent Computer Vision Syndrome
Sports – Protect Your Eyes
Shroff Eye Opener #78.
Do use safety eye wear while playing sports like Golf and Squash as there are higher chances of eye injury as the small sized balls can hit the eye directly as against larger balls which would hit the bony rim of the eye socket

DO check your children’s eyes if they are squinting, rubbing or excessively blinking their eyes
Shroff Eye Opener #38.
DO teach your child to never look directly at the sun (especially during an eclipse).
When should children undergo their first eye exam?
Shortly after birth, the doctor gives an infant its very first eye exam, but this precaution screens only for serious, congenital conditions, not quality of eyesight.
Generally, your child should undergo a vision screening around age three.
Frequency of eye examination:
Whether or not vision problems are detected in the initial screening, children should continue to undergo annual exams through the age of 10 or so. Regular eye exams should be performed throughout the teen years if problems do begin to manifest themselves. Eyesight quality often fails to stabilize until adulthood; thus, prescriptions and treatment plans may need to be updated regularly before the age of 18.
The Importance of Regular Eye Checkups for Adults
Adults with no signs or risk factors for eye disease should get their eyes checked at the age of 40 years – the time when early signs of disease and changes in vision may start to occur.
Presbyopia affects most people in their 40s. At some point, nearly everyone begins to notice blurry vision when looking at things close up, as when reading, using the computer, or sewing.
Macular Degeneration Macular degeneration produces a very distinctive pattern of vision loss and distortion. The image at the very centre of the vision becomes blank, and shapes around it become twisted. The causes of macular degeneration vary, but the disease can be treated with medication, surgery, and other treatments designed specifically for macular degeneration.
Glaucoma An increase in the eye (intra-ocular) pressure is termed as glaucoma. There are many different types of glaucoma and they can cause permanent damage to the eyes. Because glaucoma signs and symptoms are not usually very noticeable in early stages of the disease, checkups by a specialist are necessary in order to prevent long-term consequences.
Early intervention – Most serious eye conditions, such as glaucoma and AMD, are more easily and successfully treated if diagnosed and treated early. Left untreated, these diseases can cause serious vision loss and blindness. Early intervention now will prevent vision loss later.
Know your family history – Many eye diseases cluster in families, so you should know your family’s history of eye disease because you may be at increased risk. Age-related eye diseases, including cataracts, diabetic retinopathy, glaucoma and age-related macular degeneration are expected to dramatically increase by the year 2020
Ophthalmologists are specially trained to provide the full spectrum of eye care, from prescribing glasses and contact lenses to complex and delicate eye surgery.
