Abstract Background Cataract surgery induces corneal endothelial cell loss (ECL). This study investigates the relationship between bottle height (BH) and ECL induced due to irrigation and aspiration (I/A) in cataract surgery and quantifies protective

Abstract In this study, we examined the rate of contamination of multi-dose ophthalmic solutions in the operating theatre and the underlying risk for infection by examining the microbiological load on the tips of the dispenser bottles. A total of 245

Background The quality of the endothelial cell layer is a major criterion for the approval of organ-cultured human donor-corneas for transplantation. We wanted to compare the predictive capacities of initial endothelial density and endothelium cell m

In this experimental study we used for the first time Tiprotec® as a solution for corneal preservation and cold storage. We compared the resultant endothelial cell morphology and viability with this obtained after preservation of the ex-vivo corneas

Ever since the first successful keratoplasty in 1905, there has been a need to store corneas for transplantation. R. Townley Paton founded the first eye bank in New York in 1944. With Helen Keller's call in 1925 for LIONS to "constitute themselves Kn
