To report a case of post-LASIK unilateral corneal ectasia.


Department of anterior segment and Refractive surgery, Rothschild Foundation, Paris.

Case report

A 33-year-old woman was referred with a history of unilateral post-LASIK ectasia in her left eye, 18 months post operatively. Her best-corrected visual acuity was 20/20 with a manifest refraction of +1.75 (–4.75 × 90). Orbscan ii® revealed an inferior steepening associated with irregular astigmatism. The preoperative Placido topographies revealed a slight skewed radial axis in the right eye associated with an inferior-superior keratometry difference of 1.6 Diopters at 3 mm. in the left eye that developed ectasia, regular symmetric astigmatism was present. Uncorrected visual acuity improved to 20/25 2 weeks after keraRing® segment insertion.
