OPTIMIZATION OF ENERGY PARAMETERS OF FEMTOLASER ANTERIOR CAPSULOTOMY IN SURGERY FOR SWELLING OVERMATURE CATARACTS

Abstract

The study included 40 patients (40 eyes) with swellingovermature cataract. These patients were divided into groups. The first group included 10 patients (10 eyes) with fibrotic changes in the anterior lens capsule, where the power offemtolaser energy exposure during anterior femtocapsulotomy was 100 %. The second group consisted of 10 patients (10 eyes) with thinning of the anterior lens capsule, where the power of femtolaser energy exposure was 60 %. The third and fourth groups were controls, 10 patients each (10 eyes) with fibrotic changes and thinning of the anterior capsule, respectively, where the power of femtolaser energy exposure was 80% (recommended by the manufacturer of the laser unit). In the first and second groups, in contrast to the control, the absence of tissue bridges was achieved in almostall cases.The carved disc stood out freely, without additional traction, leaving no burrs. These burrs cause radialization of the anterior capsule during manipulation during cataract surgery.As a result of the study, the optimal values of the power of femtolaser exposure were selected for anterior femtocapsulotomy in case of detection of fibrosis or thinning of the anterior lens capsule in case of swelling overmature cataract.
