Simulation of vision with post-Lasik Ectasia

The image below is a computer enhanced image demonstrating how one of my patients with post-LASIK corneal ectasia sees the world. As you can see from this image, the patient may be able to identify the 20/20 line on the acuity chart. However, there is a significant difference between quality vision and quantity vision. Many patients with “higher order aberrations” like this patient were told by their LASIK doctors that they should not complain since they are identifying the small letters on the acuity chart. Properly fit scleral lenses have the ability to correct this type of vision. For this reason, members of this forum suffering from this type of vision should not give up hope.
