The authors present five cases of bilateral corneal disorders, on which they performed penetrating keratoplasty. All five patients were clinically blind and after the surgery on one eye, they gained their visual independence. Visual acuity, intraocular pressure, fundus examination, and ultrasonography were used to evaluate the patients before and after the surgery.

UNLABELLED Backgound: Chitosan/polyvinyl alcohol corneal cap has good biocompatibility and drug slow release characteristics, which provided new treatment method for anterior segment disease. Our study was to evaluate biocompatibility of poly (vinyl alcohol)/chitosan corneal shield's intraocular and investigate its feasibility to treat ocular surface disorders. METHODS Thirty-six white rabbit...

The management of corneal ectasia is evolving, with intrastromal corneal ring segments playing an important role in delaying or eliminating the need for penetrating keratoplasty. This paper describes a modification in the implantation technique of intrastromal corneal ring segments that allows for coupling of the two segments with suture, affording more structural support.

PURPOSE To investigate the potential inhibitory effects of RNA interference-mediated knockdown of neuropilin-2 (NP2) on inflammation-induced corneal hemangiogenesis and lymphangiogenesis, and whether selective inhibition of lymphangiogenesis on vascularized recipient beds before transplantation improves the graft survival. METHODS Mouse lymphatic endothelial cells were transfected with the pl...

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...

purpose : to evaluate the effects of topical sesame oil in the treatment of severe corneal alkali injury in rabbits methods : in a double-blind experiment, 30 healthy white rabbits were randomized into a sesame oil treatment group (n=15) and a control group (n=15). under general anesthesia, severe corneal alkali injuries were induced by application of 1 n sodium hydroxide for 40 seconds to the ...

purpose: to present two patients with acute corneal hydrops, superimposed with infectious keratitis using topical steroids. patients and findings: the first case was a 44-year-old man with acute corneal hydrops in his left eye which was on topical steroids for one week. visual acuity was hand motion at presentation and there was a large epithelial defect with stromal infiltration and corneal ed...

Background: To investigate the relationship between high-order aberration (HOA) changes and RCST/CT (residual corneal stroma thickness/corneal thickness) after femtosecond LASIK surgery.
