comman questions on laser eye procedures

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 which come from having an odd shaped cornea. These reflect as cylindrical powers in your spectacles or toric in lenses. With our laser, we can treat astigmatism as high as minus 6-6.5 D effectively, of course provided you fit into the overall eligibility. In some cases we may need to suggest LASIK XTRA which reinforces the corneal strength https://www.lasikindia.in/?s=astigmatism


Can laser eye surgery fix both near and farsightedness?

When you say near sightedness it means myopia or minus powers. Far sightedness is hyperopia which also can be treated which are plus powers needed to see distance objects. However, presbyopia or reading numbers or powers for near, cannot be treated permanently as this will change as you age. Learn more on https://www.lasikindia.in/why-lasik/

How laser eye surgery corrects vision?

The laser, usually the excimer laser, which is a cool beam laser, reshapes the surface of the cornea, the new shape being the one analyzed from the data done during the pre-LASIK check up with the doctor. In our centres, Shroff Eye in Mumbai, Dr Anand Shroff, does the LASIK specific tests himself. The myopia or hyperopia or astigmatism are thus treated.  Write to us or visit the website www.lasikindia.in for more information

It is a personal choice to opt for laser eye surgery.

Some do it for careers like army, navy, defense, air force, commercial pilot, railways etc, as good eyesight without glasses is mandatory for such careers. See more on www.lasikindia.in


Can laser eye surgery go wrong?

Absolutely. It is a ‘surgery’ at the end of the day. To have a successful outcome there is not one factor but several that need to be looked into. You not being the ideal candidate, or the surgeon not having enough experience, or the laser being outdated or not kept in its optimal condition, infection control methods in the Clinic or centre, these are just some factors where things can go wrong. There may be certain adverse effects or complications that you must be informed about. Read more on https://www.lasikindia.in/complications/

Excimer is the technology of the laser machine that treats spectacle powers. There are many ‘brands’ of excimer lasers in the world today. We at Shroff Eye, Mumbai recommend the wavelight (Alcon) 500 Hz laser, as it is very dependable, predictable and accurate, safe.


What is wavefront laser eye surgery?

Wavefront-guided LASIK, also referred to as custom LASIK or wavefront LASIK, is when in addition to treating a patient’s basic refractive error (spectacle power), specific alterations in a patient’s eye (high order aberrations) can also be treated. Here special mapping using a wavefront analyzer (aberrometer) needs to be done. Many centres do not have a wavefront analyzer and only rely on their clinical findings and the Topography maps. The wavefront measurements identify irregularities in the patient’s optical system and when these are severe, they can affect vision quality, contrast sensitivity, and night vision. The goal is to achieve a more optically perfect eye.


Which laser eye surgery is best for me?

This is a good question. But one must know that today with advances there are broadly three ways of LASIK or laser eye surgery- viz Wavefront or Custom LASIK, Bladeless LASIK and ReLex smile. There are off shoots such as PRK, Epi-LASIK, Advanced Surface Ablation and Contoura or Topography guided LASIK.

Is laser eye surgery covered by insurance?

This totally depends on the Insurance Company, whether they tag LASIK under cosmetic and do not cover it in general or some private insurance companies may include it, sometimes for powers above minus 7 or higher.


Can laser eye surgery be done twice?

Yes, when possible. This is called retreatment. One needs to be examined to see if the cornea is healthy and strong to take another treatment.


Why is laser eye surgery dangerous?

Laser Eye Surgery is not at all dangerous, unless of course done under an outdated laser, without proper evaluation or precautions, or in the hands of an inexperienced surgeon, or if you are not the ideal candidate, but still undergo the procedure, then in these not so ideal circumstances, then results can be compromised. Read the advanced safe methods on www.lasikindia.in


Can laser eye surgery make you blind?

Even in poorly staffed, poorly managed centres, this possibility is rare. Unless there is some serious infection due to poor infection control. There are some cases where their sight has worsened when they have lost lines of sight due to some complication. That is why the research into a good clinic and good reputed surgeon are important besides focussing just on the laser technology being applied.

Can laser eye surgery be reversed?

Can laser eye surgery correct a lazy eye?

No! Lazy eye is due to the inactive eye not in use for many years, due to which one or few lines of the visual chart are not ‘read’ by the brain. LASIK in short only replaces your current visual aid…be it contact lenses or glasses. Although, cases with lazy eye can undergo LASIK, however, they should not expect it to ‘fix’ or treat their vision to be better than what it is with their best corrected visual aid.

What is laser eye surgery for glaucoma?

The laser used in Glaucoma is not the one that our doctor recommends which if you mean is the SLT. This technology has not worked. Glaucoma needs constant monitoring of not just the IOP or eye pressure but also the status of the optic nerve and field of vision. Make sure that you are well taken care of as loss of vision in this condition is irreversible!
