Objective- This study was performed to evaluate and compare grossly and pathologically two surgical techniques of amniotic membrane patching on experimental corneal alkali burn in dogs.   Design- Experimental study.   Animals- Fifteen healthy dogs   Procedures- The central corneas of the dogs were inflicted by applying a round filter paper, 6.0 mm in diameter, soaked in 1 N NaOH for 60 sec. ...

purpose : to determine the efficacy of fibrin glue in corneal perforations up to 3 mm in diameter methods : a case series study was performed on corneal perforations up to 3 mm who were admitted at farabi hospital- tehran. age, visual acuity, presence and size of corneal thinning, corneal epithelial defect, size and depth of corneal infiltration, site and size of corneal perforation, corneal va...

purpose: to determine the sensitivity and specificity of posterior corneal elevation in discriminating keratoconus and subclinical keratoconus from normal corneas by galilei and orbscan ii diagnosed on the basis of topography. methods: three groups (keratoconus, subclinical keratoconus and normal) were evaluated with galilei and orbscan ii and results were compared to those obtained by gold sta...

purpose: to evaluate the efficacy of riboflavin administration and ultraviolet a (uva) cross-linking on advanced symptomatic bullous keratopathy (bk). methods: 10 patients with symptomatic pseudophakic bullous keratopathy (pbk) were included. slit-lamp examination, visual acuity, foreign body sensation (fbs) and corneal thickness as measured by pentacam, were performed before corneal cross-link...

purpose: to evaluate the ability to predict visual outcome after penetrating keratoplasty (pkp) in patients with pseudophakic or aphakic corneal edema (pce or ace). methods: medical records of 34 patients (34 eyes) who underwent pkp for pce or ace during 1994-2004 in ahvaz were retrospectively analyzed for variables in the history and ocular examination before pkp and visual outcome after pkp. ...

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...

purpose : to evaluate the correlation of central corneal thickness (cct) with refractive error and keratometry in a group of patients eligible for laser keratorefractive surgery, which may serve as a bias in studies on intraocular pressure (iop) measurement methods : in a cross sectional observational study, the right eyes of 340 patients who underwent laser keratorefractive surgery during the ...

results the mean udva (logmar) improved significantly from 1.13 ± 0.21 preoperatively to 0.24 ± 0.13 postoperatively (p < 0.001), and the mean cdva (logmar) improved significantly from 0.39 ± 0.12 to 0.19 ± 0.09 (p < 0.001). the mean cylinder of manifest refraction decreased significantly by 4.00 diopter (d) (p < 0.001). the mean spherical equivalent error (se) decreased significantly from −6.0...
