purpose : to investigate the application of mitomycin-c 0.02% (mmc) in the photorefractive keratectomy (prk) procedure in correcting regressed myopia methods : eighteen eyes of 11 patients with a spherical equivalent (se) of less than -5 diopters (d) who had undergone laser in situ keratomileusis (lasik) more than 2 years before were operated on. at the end of the prk procedure, mmc was applied...

AIM To compare the visual acuity (VA), spherical equivalent refractive error, motility, and anatomical outcomes in children with treated regressed threshold stage 3 retinopathy of prematurity (ROP) and those with spontaneously regressed subthreshold stage 3 ROP. METHOD 6 month and 3 year data collected from infants examined between 1989 and 1999 with regressed stage 3 ROP, with or without tre...

purpose: to evaluate visual outcomes after deep anterior lamellar keratoplasty (dalk) in patients with keratoconus. methods: in this interventional case series, patients with moderate to advanced keratoconus underwent dalk. inclusion criteria consisted of contact lens intolerance or poor spectacle-corrected visual acuity. dalk was performed using the big-bubble technique introduced by anwar and...

PURPOSE We investigated longitudinally the refraction development in children with regressed retinopathy of prematurity (ROP), including those with and those without a history of peripheral retinal laser photocoagulation. METHODS Longitudinal (0-7 years) cycloplegic refraction data were collected prospectively for two groups of preterm children: severe ROP group included those with regressed ...

background : phacoemulsification is one of the best surgical treatments for the cataract. secondary to the technicaladvances in estimating the intraocular lens (iol) power, the refractive errors, one of the most important surgical complications after surgery, is now reduced. currently, two methods of biometry are used to calculate the iol power, ultrasound biometry and optical biometry. both me...

purpose : to determine the prevalence of refractive condition and its risk factors among students in mashhad . methods : a total of 2510 students representing a cross-sectional of the population of mashhad were sampled using random cluster sampling strategy. primary and middle school students underwent cycloplegic refraction. the refractive errors of high school students were measured using non...
