Hello doctor,

I have an exotropia squint in my right eye from the last 10 to 12 years. Presently I have a very low vision in that eye and near and far vision is blurry. I consulted an ophthalmologist and he recommended a LASIK surgery and after that a squint correction surgery a month later. Should I go for that? I am attaching my prescription for your reference.

Hello,

Welcome to icliniq.com.

I have gone through your images (attachment removed to protect patient identity).

You can proceed with the LASIK surgery and the squint correction as advised but please keep the following in mind:

  • Your right eye is amblyopic (lazy eye). So, the vision even after a LASIK will be 6/18 p and not 6/6.
  • As your eye power is very high, you will have some residual power even after the LASIK.
  • Moreover, your squint is also very large. So, you may need to get both eyes operated for the squint correction. Even after this surgery, there will be a residual deviation.

Do discuss with your doctor regarding these points.

Hello doctor,

Thanks for your reply. But, I am confused. What I understand is that there is no solution for my eye problem. It will be the same even after surgery. Am I correct?

Hello,

Welcome back to icliniq.com.

Sorry, I did not mean that. I am just asking you to keep your expectations a little low.

Regarding squint, you may need to get both the eyes operated for this large an angle of exotropia. Surgery gives a favorable outcome in 90 % of the patients but a little under or overcorrection is possible.

Regarding LASIK, there are two aspects to understand:

  1. As your right eye seems amblyopic, the vision in the right eye will be 6/18 even after the LASIK. That is, it will be less than your left eye.
  2. You have very high myopia in the right eye. So, there may be some residual refractive error even after LASIK.

I am not discouraging you and I would recommend these surgeries for you. But, sometimes patients have huge expectations from surgery. I am just requesting you to understand the fact and outcome of surgery. The difference in corneal thickness of two eyes is around 40 micron. For such a huge difference, I usually repeat pachymetry.

I hope this helps. Regards.
