PURPOSE To improve the visual acuity of patients with progressive keratectasia following laser in situ keratomileusis (LASIK). METHODS Five eyes of four patients underwent penetrating keratoplasty for ectasia after LASIK: In one patient the second eye was operated on 10 months after the first keratoplasty. The pre- and postoperative refraction, best spectacle-corrected visual acuity, and topo...

To the Editor: We read the recent article by Tuwairqi and Sinjab,1 which appeared in the May 2012 issue of the Journal of Refractive Surgery, and would like to offer some comments. Tuwairqi and Sinjab, in this prospective and noncontrolled study, performed corneal collagen cross-linking (CXL) in patients with stage 1 or 2 keratoconus pretreated with topography-guided photorefractive keratectomy...

Background: Lasik-Laser in situ keratomileusis is by for the predominant refractive procedure use today. We are beginning to learn both its full potential and limitations. This includes refining our knowledge about how much error can be corrected with LASIK while maintaining a high quality of vision. Aim: To evaluate compare outcome performed patients mild, moderate severe myopia using SCHWIND ...

purpose : to review the visual outcome and complications of deep anterior lamellar keratoplasty (dalk) using the big-bubble technique in patients with corneal ectasia methods : eighteen consecutive patients with keratoconus or post-lasik ectasia with poor spectacle-corrected visual acuity and/or contact lens intolerance were enrolled in this study between october 2005 and september 2006. dalk b...
