Lasik Ectasia 3 years after Lasik

The image shown below was taken with a computerized corneal topographer. The upper colored images show the corneal topographies of a 30 year old patient with post-LASIK corneal ectasia. This condition took place 3 years after the LASIK surgery was done. The red areas shown below represent the parts of the cornea that are protruding or “bulging” forward. This patient’s unaided visual acuity is less than 20/1000 in each eye. His eyeglass correction is now in excess of -20.00 in each eye. Look carefully at the lower images and not that his pupil diameter is 8.6 mm (in dim lighting). The LASIK created treatment zones are 6.5 mm or less, making it impossible to correct his visual error. This patient, by the way, underwent LASIK when he was 17 years old. He is now wearing scleral lenses which are allowing him to see 20/25 with each eye without any distortions.
