Keratoconus (KC) is a progressive, bilateral, but usually asymmetrical ecstatic corneal disease, characterized by progressive corneal protrusion and thinning, that leads to corneal surface distortion. The reported incidence in the general population varies from 1.3 to 25 per 100,000 per year across different populations, with a prevalence of 8.8–229 per 100,000. Onset typically is at puberty wi...

Aims: To analyse the outcome of DALK in patients with keratoconus terms best corrected and uncorrected visual acuity, average K topographic astigmatism. Settings design: Prospective interventional case series study Material methods: 28 eyes diagnosed were evaluated from August 2009 – July 2011 a tertiary eye care hospital. All underwent outcomes assessed on 4 parameters: Average Keratometric re...

OBJECTIVE To assess the cost-utility of posterior lamellar keratoplasty (PLK) techniques, including deep lamellar endothelial keratoplasty, Descemet stripping endothelial keratoplasty, and Descemet stripping automated endothelial keratoplasty, in the treatment of corneal endothelial diseases. DESIGN Cost-utility analysis based on a Markov model. PARTICIPANTS Cohort of 100 patients waiting f...

purpose: to investigate the results of deep lamellar keratoplasty (dlk) by big bubble method with using shifting bubble sign in patients suffering from keratoconus or corneal opacity methods: in this prospective interventional clinical trial, 20 eyes of 18 patients (10 males and 8 females) who underwent dlk by big bubble method using shifting bubble sign were investigated. mean age of cases wer...
