Phacorefractive surgery in patients with high myopia
Abstract
Introduction: myopia is an ametropia with a high prevalence index that causes a decrease in visual acuity. Phacorefractive surgery, or removal of the clear lens and its replacement by an intraocular lens, represents a therapeutic option for this condition.Objective: to characterize from the demographic, clinical and surgical point of view those operated on for high myopia by means of phaco-refractive surgery.
Methods: a prospective descriptive observational study was carried out on all patients of 40 years or more (34 patients, 66 eyes) with high myopia who attended the Ophthalmological Center of the Ciego de Ávila province between January 2011 and October 2017. Ethical precepts were followed.
Results: the female sex predominated (61,76 %) and the age group from 40 to 44 years (70,59 %). Most of the patients (86,36 %) improved visual acuity without correction in the postoperative period. In almost all the operated eyes (92,42 %), endothelial cell loss occurred. Sphere and cylinder values were reduced, and astigmatism was not induced. Only 10,52 % of the operated eyes were complicated: in the perioperative the complication was ocular hypertension (3,52 %); in the postoperative period the acute anterior uveitis (2,52 %) and in the late postoperative period, the opacity of the posterior capsule (5,52 %).
Conclusions: young adults and women predominated. Phacorefractive surgery, although not without risks, constituted a safe and corrective therapeutic guarantee in patients with high myopia.
