Certezas ante la incertidumbre : élite y Cabildo de Quito en el siglo XVII

Abstract

This review covers last year's literature on corneal, limbal, and conjunctival transplantation including tissue storage and eye banking. In this area, the main themes were related to a better evaluation of tissue viability and the exclusion of disease transmission. An analysis of the changing indications for penetrating keratoplasty shows the differences between American and European series. Most efforts in relation to surgical techniques are oriented toward obtaining better refractive results, whereas the study of large series sheds new light on the risk factors for graft failure and other complications. Limbal transplants have acquired the status of a new field in the surgical treatment of ocular surface disease, particularly in relation to corneal stem cell deficiencies.
