Purpose: To determine the etiologic factors on rejection and failure rates and ocular surface changes after corneal transplantation by either DALK or PKP, in cases of keratoconus (KCN). Methods: In this cross-sectional study, considering the existing data, patients with keratoconus referring to Labbafinejad Medical Center from 2006 to 2016, who underwent corneal transplantation, were enrolled a...
Background: Keratomycosis is a fungal infection of the cornea which could be sight-threatening and even causes eye loss. Considering the high humidity and the dominance of agriculture as important predisposing factors of keratomycosis in north of Iran, this study was carried out for diagnosis of fungal keratitis in patients with corneal lesions in Rasht, Gilan province, Iran. Methods: This de...
Background: In this study were focused on corneal cells changes in keratoconus disease, as there are differences between results of other studies that were done on keratokonic eyes. And the chief purpose was a comparison between keratoconus and normal population based corneal endothelium (in cell density, pleomorphism and polymegethism of cells). Methods: This study is an observational study a...
This study was performed to evaluate the efficacy of anterior keratoplasty with microkeratome in the improvement of visual acuity (V.A) in superficial corneal disorders in patients admitted to Labbfi Nezhad hospital and Tehran Bassir Clinic . &nbs...
Background: Keratoconus is a common complication among corneal defects. As a result of expeditious and extensive progress of medical science in recent decades, corneal ring implantation has turned into a successful surgical procedure to correct the vision of Keratoconus patients; however, selecting the right patient is essential in the success of the operation. The prediction of corneal conditi...
purpose : the aim of this study was to determine indications of keratoplasty during 7 years (1999–2006) in emam-rreza and vali-asr teaching hospitals of birjand university of medical sciences. methods : medical records of all patients who underwent penetrating keratoplasty (pk) in teaching hospitals of birjand university of medical sciences from 1999 to 2006 were investigated retrospectively. t...

Background and Objective: Evaluation of the results, safety, and stability of ferrara intracorneal ring segment (FICRS) implantation for Keratoconus correction (age range was 24.39±8.32 years). Materials and Methods: In this clinical trial study, 64 eyes of 57 patients with keratoconus and clear cornea that had FICRS implantation were studied. Uncorrected visual acuity (UCVA), best-spectacl...
PURPOSE To report on the therapeutic effect of intravitreal low-dose bevacizumab for treatment for retinopathy of prematurity (ROP). METHODS The single-centre retrospective, non-comparative case series study included all infants who consecutively underwent intravitreal injection of 0.375 mg bevacizumab (0.03 ml) under light sedation in topical anaesthesia as therapy of ROP in zone I or zone I...
purpose: to evaluate the correlation between corneal power and corneal horizontal white to white diameter in myopic patients scheduled for lasik surgery. methods: overall, in 840 eyes of 420 myopic subjects scheduled for lasik, horizontal white to white diameter and mean corneal power were obtained using orbscan ii. pearson correlation test and regression analysis were used to detect any correl...
