Introduction: The cornea is a transparent organ responsible for 60% of the refractive power of the eye. According to the World Health Organization (WHO), diseases affecting the transparency of the cornea are responsible for 5.1% of total of about 45 million blind. Brazil is the country that performs corneal transplants in Latin America. Endothelial loss rate is around 0.6 / year in normal people. This rate is accelerated after eye surgery or glaucoma. This loss after penetrating keratoplasty because initial trauma, immune reaction, secondary glaucoma, cell interaction between donor and recipient, it would be 7.8% / year in the first five years and 4.2% / year after 10 years. Some studies suggest a greater endothelial cell loss in DSAEK (34% after six months) than in penetrating keratoplasty (11%) while others show that endothelial cell loss after one year is higher in penetrating keratoplasty. Graft survival in both techniques were similar and higher optical result in DSAEK technique. For nearly a century the penetrating keratoplasty has been surgical technique of choice in the management of corneal changes. Despite the advantages of lamellar procedures such as intraocular lower risk of complications and graft rejection further shows penetrating keratoplasty is the preferred technique of most of the world transplant. However, in recent years, several lamellar keratoplasty techniques have been developed, modified or improved, especially techniques for replacement of the posterior portion for correction of bullous keratopathy. Objective: To evaluate the efficacy and safety in endothelial keratoplasty when compared to penetrating keratoplasty for the improvement of visual acuity in aphakic and pseudophakic bullous keratopathy. Methods: Systematic review of randomized controlled trials (RCTs) and / or quasirandomized studies that assessed endothelial keratoplasty versus penetrating keratoplasty in adults diagnosed with aphakic or ...
