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...
purpose : to report a case of recurrent corneal intrastromal cyst containing lymph fluid case report : a 13-year-old girl presented with recurrent cyst of the left cornea, which had been drained three years before, but had gradually recurred. the cyst was successfully drained. histologic examination, cytologic analysis, and protein electrophoresis were performed on the cyst fluid. histopatholog...
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 In this study, we tried to investigate weather or not the preoperative anterior chamber depth, the lens thickness (LT) and the relation between these variables by the ratio (K) of the distance from the corneal peak to the posterior side of the lens (A) (K = A/LT) could be predictive for a surgically induced foveal thickening following uneventful cataract surgery in normal, emmetropic ey...
A 69 years old women underwent uneventful cataract surgery of her left eye with phacoemulsification and posterior chamber intraocular lens implantation in topical anesthesia. Patient was postoperatively treated with combination of antibiotic and steroid in decreasing dosages during five weeks: one drop five times a day the first week, three times a day second to forth week and one time a day th...
Report of a Case. In March 2002, a 35-year-old patient from Saudi Arabia presented with a massive corneal clouding that had been slowly progressive over the last 5 years. He said he had been practically blind for 2 weeks. When we first saw him, his visual acuity was light perception in both eyes. His history was uneventful, in particular with regard to ocular trauma or infectious diseases. No s...
