Welcome to icliniq.com.

I shall try to answer all your queries in detail.

Aniseikonia occurs when the difference in refractive error is more than 4 or 5 diopters between two eyes.

If you say you had laser-assisted cataract surgery which means a femto surgery, the size of incision would be perfect. So, basically, the reason for your aniseikonia would be:

  1. Wrong dioptric power.
  2. Wrongly placed lens.
  3. Corneal edema.
  4. Retinal edema.
  5. Also, there can be a reason in which due to sudden improvement is visual acuity of the operated eye you can have double vision in the non-operated eye.

Now, I have told you the option if the wrong lens were implanted, that is, if power error is less than 2 to 3 D one can go for contacts or spectacles but if power error is more than 4 to 5 D one has to go for IOL (intraocular lens) exchange.

To diagnose rest, you have to go for an investigation known as Pentacam and OCT (optical coherence tomography).Follow up with results.
