Corneal collagen crosslinking in post-LASIK keratectasia.
BACKGROUND/AIMS To evaluate the effect of corneal collagen crosslinking with riboflavin and UV-A as a treatment option for postlaser in situ keratomileusis keratectasia. METHODS Crosslinking was carried out in 22 eyes of 15 patients with iatrogenic keratectasia. Follow-up, according to a standardised protocol (uncorrected visual acuity (UCVA), best-corrected visual acuity (BCVA), slit-lamp ex...
متن کاملThe shape of posterior corneal surface in normal, post-LASIK, and post-epi-LASIK eyes.
PURPOSE. To evaluate the shape of the posterior corneal surface in eyes with normal myopia or myopic astigmatism and the changes after LASIK and epi-LASIK. METHODS. A total of 152 eyes were included in the study. The posterior corneal elevation was measured with Scheimpflug imaging (Pentacam; Oculus, Wetzlar, Germany), before LASIK or epi-LASIK and at 1 and 6 months after surgery, along the fou...
متن کاملRelation of pre-LASIK and post-LASIK retinal lesions and retinal examination for LASIK eyes.
AIMS Analysis of highly myopic eyes (mean myopia -11 D) with post-LASIK vitreoretinal complications (breaks, retinal detachment) that also had pre-LASIK vitreoretinal pathology (lattice, breaks). METHODS Retrospective case series. RESULTS 67 eyes in 56 patients with pre-LASIK retinal examination developed post-LASIK vitreoretinal complications. 17 of the 67 eyes (25.4%) had pre-LASIK vitreo...
متن کاملPrimary Open Angle Glaucoma and Post-LASIK Keratectasia
The patient presented herein is a 52-year-old woman suffering from primary open angle glaucoma (POAG) in both eyes. She has no history of systemic disorders and is not on any systemic medications. She underwent laser in situ keratomileusis (LASIK) 9 years ago for refractive error of -5.50-3.00×180 in both eyes, and was diagnosed with glaucoma 7 years afterwards. Her ocular examination when I sa...
متن کاملProgressive post-LASIK keratectasia: biomechanical instability or chronic disease process?
Progressive post-LASIK keratectasia (PPLK) is a progressive deformation of corneal anatomy that occurs rarely but may have severe consequences. Using the scientific literature and new hypotheses, we attempted to determine whether PPLK is a biomechanical result of laser in situ keratomileusis (LASIK), a chronic disease process affecting individuals predisposed to the condition, or a combination ...
