PURPOSE To evaluate the keratometric and pachymetric parameters of keratoconic corneas of Asian eyes with the Scheimpflug imaging camera. PATIENTS AND METHODS This is a cross-sectional study of 22 eyes with Amsler-Krumeich stage 1 keratoconus and 48 eyes from normal subjects conducted in a tertiary eye hospital. A rotating Scheimpflug imaging system, the Pentacam, was used to evaluate all eye...

purpose: to evaluate the histopathologic features of optic neurotomy with microvitreoretinal (mvr) blade and excimer laser in cadaver eyes. method: optic neurotomy was performed in 11 cadaver eyes using 20-gauge mvr blade and in three cadaver eyes with pulsed xenon chloride (xecl) excimer laser (308 nm) via monofile light-conducting fiber with a core diameter of 200 microns. after tissue proces...

PURPOSE To report results of a series of highly aberrated corneas treated with a topography-guided excimer laser ablation. METHODS Retrospective, nonrandomized, consecutive series of eyes treated with topography-guided photorefractive keratectomy (TG-PRK) with the customized topographical neutralization technique (TNT). Cases included postoperative refractive surgery decentered ablations, opt...

PURPOSE To evaluate refractive and visual outcomes of secondary piggyback intraocular lens implantation in patients diagnosed as having residual ametropia following segmental multifocal lens implantation. METHODS Data of 80 pseudophakic eyes with ametropia that underwent Sulcoflex aspheric 653L intraocular lens implantation (Rayner Intraocular Lenses Ltd., East Sussex, United Kingdom) to corr...

OBJECTIVE To evaluate the quality of vision (visual acuity and straylight) in patients with Fuchs dystrophy and the improvement in visual quality after Descemet stripping endothelial keratoplasty (DSEK). METHODS There was an observational case series (Amsterdam group) and a prospective interventional case series (Mayo group). Corrected distance visual acuity (CDVA), straylight, and corneal th...

PURPOSE To investigate the safety, efficacy, and stability of transepithelial photorefractive keratectomy (PRK) for hyperopia. METHODS This interventional case series study at two sites included 55 eyes (31 patients) with hyperopia (0.50 to 6.00 diopters [D]), with or without astigmatism (0.00 to -3.00 D), that underwent one-step transepithelial PRK with a Amaris 500-Hz excimer laser (SCHWIND...

PURPOSE To assess short-term clinical outcomes after implantation of phakic intraocular lenses (Visian ICL, STAAR Surgical Co) in US military warfighters who are not good candidates for laser vision correction. METHODS A retrospective interventional consecutive case series analysis of all eyes that underwent ICL surgery during a 14-month time period was performed. Main outcome measures includ...
