Cataract surgery in corneas with low endothelial cellular density
Abstract
Introduction: Cataract surgery in patients with low corneal endothelial cell count represents a challenge due to any of its techniques and it is associated with an additional loss of endothelial cells beyond what is physiological.
Objective: To describe clinical and surgical aspects in patients with low corneal endothelial cell count who underwent cataract surgery at the Ophthalmological Center of the province of Ciego de Ávila.
Methods: Pre-experimental study (before and after) that included 41 eyes (36 patients) with low endothelial cell count who underwent cataract surgery between March and November 2022, at the Cataract Service of the Ophthalmologic Center of Ciego de Ávila province. There were analyzed variables such as age groups, sex, personal systemic and ocular pathological history, preoperative and postoperative cell count, as well as the presence and type of corneal edema according to surgical technique.
Results: The majority were people over 70 years of age (44.4%) with a predominance of females among all age groups (61.1%). Glaucoma and diabetes mellitus were more common as ocular and systemic pathological antecedents (34.1% and 30.6% respectively). There was a slightly greater percentage decrease in endothelial cell density (18.7%) in eyes operated on by phacoemulsification. Most patients did not present postoperative corneal edema (63.4%).
Conclusions: It is common to find older female adults with low corneal endothelial cell count. Despite the postsurgical loss, more than half of the patients did not present corneal edema after cataract surgery due to any of the techniques used.
