Background : Posterior corneal elevation changes are keys to early diagnosis of corneal ectasia after keratorefractive surgery, so it is important to use an accurate method for measuring posterior corneal elevation. The purpose of this study is investigating posterior corneal elevation changes with Pentacam(HR) on patients underwent photorefractive keratectomy. Methods: In this clinical tri...
متن کاملManagement of corneal ectasia after LASIK with combined, same-day, topography-guided partial transepithelial PRK and collagen cross-linking: the athens protocol.
PURPOSE To evaluate a series of patients with corneal ectasia after LASIK that underwent the Athens Protocol: combined topography-guided photorefractive keratectomy (PRK) to reduce or eliminate induced myopia and astigmatism followed by sequential, same-day ultraviolet A (UVA) corneal collagen cross-linking (CXL). METHODS Thirty-two consecutive corneal ectasia cases underwent transepithelial ...
متن کاملEnhanced ectasia screening: the need for advanced and objective data.
To the Editor: We read with interest the report from Drs. Abdulmassih-Gonçalves and Gonçalves.1 The authors should be commended for publishing a case of ectasia after LASIK, which was detected and addressed by collagen cross-linking. We also appreciate their willingness in sharing the preoperative raw data from rotatingScheimpflug tomography, which generated interesting information that we addr...
متن کاملEctasia risk factors in refractive surgery.
This review outlines risk factors of post-laser in situ keratomileusis (LASIK) ectasia that can be detected preoperatively and presents a new metric to be considered in the detection of ectasia risk. Relevant factors in refractive surgery screening include the analysis of intrinsic biomechanical properties (information obtained from corneal topography/tomography and patient's age), as well as t...
متن کاملPentacam HR criteria for curvature change in keratoconus and postoperative LASIK ectasia.
PURPOSE To determine criteria for keratoconus or postoperative LASIK ectasia progression or improvement based on Pentacam HR (Oculus Optikgeräte GmbH) measured steepest corneal curvature. METHODS Sixty-one eyes from 41 patients with keratoconus or postoperative LASIK ectasia were evaluated. Each eye was measured 5 times with the Pentacam HR during the same clinic visit and the random measurem...
