Results of the application of the Nd: Yag Laser in cataract operated with posterior capsule opacity
Abstract
Introduction: opacity of the posterior lens capsule is the most frequent late postoperative complication of cataract surgery, associated with decreased vision. Posterior capsulotomy with neodymium YAG laser is the choice treatment.
Objective: to evaluate the efficacy of the application of posterior capsulotomy with neodymium YAG laser in patients with opacity of the posterior lens capsule, developed after cataract operation.
Methods: a pre-experimental study was carried out in the universe of 126 patients (135 eyes) operated on for cataract who developed opacity of the posterior capsule, treated at the Ophthalmological Center of Ciego de Ávila between January and December 2019. Data were extracted from individual medical records. Descriptive and inferential statistics were applied. Bioethical principles were met.
Results: female patients (57,14 %), the age group from 70 to 79 years (39,68 %) and the ocular pathological history of simple chronic glaucoma (8,73 %) predominated. The most frequent complication was damage to the intraocular lens (15,56 %). The mean value of intraocular pressure was 14,5 mm Hg before capsulotomy, and 15,4 mm Hg two hours after. Visual acuity one month after the procedure improved in most patients.
Conclusions: the opacity of the posterior capsule maintains a high incidence in cataract surgery. Neodymium YAG laser treatment was effective in achieving a positive and significant modification of best-corrected visual acuity, with a minimum of complications.Downloads
