Q What is monovision LASIK?

Ans.  Over 40 years of age everyone gets reading glasses, no one is exempt of it. Some people get this ‘plus’ or ‘reading glasses’ after 50 years, hence this depends from person to person, different race, hereditary factors etc. But all get it at some point, if this happens after 40 years it is an acceptable natural change in the optics of your eyes, called ‘Presbyopia’.

If one has myopia (minus numbers for distance), it helps you push the need for reading glasses behind by a year or so. Hence, if a Myopic who is not using glasses for reading were to do LASIK today, yes he/she would need reading glasses, depending on when they would have naturally got them.

Now, the reading glasses is something that one can never avoid completely, so eventually it Myopics will need to use bi- focals.

Monovision is an option wherein we correct myopia completely for one eye and leave behind a minor number in the other. It sounds odd, but over time one learns to read the distance with the eye good for far vision and reads near for comfortable print by the eye left behind with a small number. This is accepted by most who wear contact lenses where their optician has given them this monovision trial in their lenses, i.e. one lens has the actual number so you read clearly with this and the other lens is slightly under corrected so you read near with this. Now, when one wants to do extensive near reading it may be a strain.

So, we recommend them to use near glasses as per what is required for their age when they are doing near work for a long time. When we have performed monovision for people who have never undergone the monovision trial, we have found that they are neither happy for far, nor happy for near. My suggestion to you is to see your optician and get contact lenses which will give you a trial and see how you feel with this for about 2-3 weeks if you plan on monovision. This will give you an idea of what your vision will be like after LASIK with monovision correction.  Hence, if you are over 40 years of age, most times it helps to learn a bit about your lifestyle and suggest what would be best, after the examination, but it certainly helps you plan better keeping all options of treatment in mind.
