Corneal Collagen Crosslinking for Keratectasia after Laser in situ Keratomileusis: A Review of the Literature
Corneal ectasia is a serious vision-threatening complication of laser in situ keratomileusis (LASIK). It is associated with progressive corneal steepening, an increase in myopia and astigmatism, and decrease in uncorrected visual acuity. Before LASIK presence of risk factors (corneal thickness, refractive error, presence of clinical and subclinical corneal pathologies) should be studied so pati...
متن کاملCorneal Collagen Crosslinking for Ectasia after Refractive Surgery.
The development of corneal ectasia has been recognized as a complication after LASIK since the first case report from Seiler and Quurke in the late 1990s. The clinical picture of iatrogenic corneal ectasia resembles that of progressive keratoconus with reduced corneal biomechanical strength, increasing central corneal steepness, irregular refractive errors, and decreasing visual acuity. Since t...

Introduction. To determine the effect of corneal collagen cross-linking treatment on keratoconus and post-LASIK ectasia particularly after an abbreviated exposure to ultraviolet light exposure. Materials and methods. Fifty-one eyes of 34 patients were treated with epithelium-off UVA-riboflavin corneal collagen cross-linking for either 20 minutes or 30 minutes as part of a US.FDA clinical study....

Purpose To describe the case of a patient developing corneal ectasia following LASIK for the correction of myopic astigmatism. Materials and Methods A 39-year-old man underwent bilateral uneventful LASIK for myopic astigmatism of -10.25 -1.75 ×040 OD and -8.00 -2.50 ×005 OS. Preoperative corneal pachymetry was 542 micrometers OD and 543 micrometers OS. Preoperative corneal topography showed b...
متن کاملA New Model for Predicting Ectasia Accounting for the imperfections of your surgical instruments can help you to avoid excessive keratectomy during LASIK
O ver the years, refractive surgeons have devised strategies for coping with some of the more common complications that can occur after LASIK. Nonetheless, ectasia, a condition characterized by a progressive increase in corneal curvature, remains somewhat of a mystery. Its most likely causes appear to be undetected preoperative keratoconus and excessively deep keratectomies. This article presen...

Ectasia After SMILE: Correct Interpretation of Biomechanical Hypothesis We read the case report by Mattila and Holopainen on bilateral ectasia after SMILE in the July 2016 issue with great interest.1 It is evident that preoperative examination with topography, tomography, and slit-lamp examination needs to be strictly followed by surgeons before small incision lenticule extraction (SMILE), LASI...
