purpose: to compare corneal endothelial cell features after cataract surgery performed using fixed torsional or conventional (pulse) ultrasound mode. methods: in this randomized comparative study, 60 eyes were randomly and equally divided into two groups of torsional or longitudinal mode phacoemulsification. all surgeries were performed by an experienced surgeon, and the outcomes were evaluated...

purpose: to assess the short-term effect of mitomycin-c (mmc) 0.02% on endothelial cell density and morphology after photorefractive keratectomy (prk) in patients with moderate myopia. methods: forty-two eyes of 21 participants with moderate myopia (range, -4.0 to -8.0 d) underwent prk with mmc 0.02% for 40 seconds. specular microscopy was performed preoperatively and repeated 6 months after su...

purpose : to compare central corneal thickness (cct), corneal endothelial cell density, and lens capsule thickness in normotensive patients with and without pseudoexfoliation syndrome (pxs) methods : this was a prospective, comparative, descriptive study. normotensive candidates for cataract surgery with (study group) and without (control group) pxs were enrolled in the study. cct and corneal e...

to evaluate corneal endothelial cell changes after intravitreal and subconjunctival injection of avastin (bevacizumab) based on specular microscopic findings.  this prospective interventional study was performed on 82 eyes of 82 patients. forty-two cases with ptrygia received a subconjunctival injection of bevacizumab (2.5mg/0.2ml) and 40 diabetic subjects with retinal neovascularization or mac...

purpose: to compare outcomes of two techniques (anwar vs. melles) of deep anterior lamellar keratoplasty (dalk) in patients with keratoconus. methods: this randomized double-blind clinical trial was performed on 57 eyes of 57 patients with keratoconus. patients aged 20-35 years with a clinical diagnosis of keratoconus who were contact lens intolerant and had corrected distance visual acuity (cd...

purpose : to report an unusual presentation of chandler syndrome case report : a 22-year-old female came to our clinic with complaint of progressive visual loss in her left eye since three days ago. she had a history of trauma with finger-nail to her left eye eight days ago and had been managed with topical antibiotic. in her examination, the left eye had visual acuity (va) of counting finger a...

purpose: to evaluate the corneal endothelial cell density and polymegathism one year after laser assisted keratomileusis using mitomycin c. methods: one hundred and three eyes from 52 patients who underwent laser assisted sub-epithelial keratomileusis using mitomycin c 0.02% for 30 seconds entered this study. corneal endothelial cells were evaluated using specular microscopy before and one year...

purpose: to evaluate corneal endothelial cells of donors who died from aluminum phosphide intoxication. methods: endothelial cell count and quality of eight corneas from four donors with aluminum phosphide intoxication were evaluated by slit lamp biomicroscopy and specular microscopy at the eye bank of i.r. iran. confocal scan examination was carried out only in one of the recipients. results: ...

PURPOSE To assess the risk factors for endothelial cell loss after phacoemulsification with implantation of intraocular lens according to anterior chamber depth (ACD). METHODS This prospective study included 94 eyes of 94 patients undergoing phacoemulsification cataract surgery. To assess the risk factors for corneal endothelial cell loss, we examined seven variables at 1 day, 1 week, 6 weeks...

BACKGROUND/AIMS Deturgescence of the corneal stroma is controlled by the pumping action of the endothelial layer and can be monitored by measurement of central corneal thickness (pachymetry). Loss or damage of endothelial cells leads to an increase in corneal thickness, which may ultimately induce corneal decompensation and loss of vision. Little is known about the effect of moderate reductions...
