Currently, filtration surgery has been considered as the most effective therapy for glaucoma; however, the scar formation in the surgical area may often lead to failure to the procedure. An implanted drug delivery system may provide localized and sustained release of a drug over an extended period. Poly (ethylene glycol)-poly (ε-caprolactone)-poly (ethylene glycol) (PEG-PCL-PEG, PECE) hydrogel ...
Surgical treatment, clinical outcomes, and complications of traumatic cataract: retrospective study.
AIM To analyze clinical outcomes and complications after traumatic cataract extractions because of post-traumatic lens opacification. METHODS We performed a retrospective analysis of 24 eyes with traumatic cataract surgically treated between May 2000 and June 2003. Preoperative visual acuity, postoperative best corrected visual acuity, and preoperative, intraoperative, and postoperative compl...
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...
AIMS/BACKGROUND In adult tissues the expression of tenascin-cytotactin (TN-C), an extracellular matrix glycoprotein, is limited to tumours and regions of continuous renewal. It is also transiently expressed in cutaneous and corneal wound healing. There are limited data regarding its expression in inflammation and scarring of the adult human cornea. In this study, TN-C expression patterns in nor...
Burn wound healing involves a series of complex processes which are subject to intensive investigations to improve the outcomes, in particular, the healing time and the quality of the scar. Burn injuries, especially severe ones, are proving to have devastating effects on the affected patients. Stem cells have been recently applied in the field to promote superior healing of the wounds. Not only...

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...
