Клинико-функциональные результаты применения методики пневмокомпрессии при факоэмульсификации возрастной катаракты

Abstract

Purpose . The analysis of clinical and functional results using the method of intraocular lenses (IOL) pneumocompression in phacoemulsification (PE) of senile cataract for the prevention of posterior capsule opacification development. Material and methods. The study included 328 pseudophakic eyes of 328 patients, who underwent PE for senile cataract. The IOL pneumocompression was performed after the viscoelastic removal in 166 eyes (the main group); the standard PE – in 162 eyes of the control group. The type of IOL-posterior capsule interface and the visual acuity (VA) were examined at the 1st postoperative day; VA, structure and transparency of posterior capsule in pseudophakic eyes were studied after 1 year postoperatively. Results . The full contact of IOL with posterior capsule was found in 84.3% of eyes in the main group and in 31.5% of eyes in the control group. One year after operation the posterior capsule was transparent in 145 eyes (87.3%) of the group 1 and in 94 eyes (58%) of the group 2, thus the values of VA in the main group turned out to be higher, than in the control. Conclusion. The conducted research showed that IOL pneumocompression method in PE of senile cataract provided an optimal interface of IOL-posterior capsule in 84.3% of operated eyes. One year after operation the number of pseudophakic eyes with transparent optical part of posterior capsule in the main group exceeded the control by 30%. However, indices of uncorrected and best corrected VA were comparable in both groups at the first postoperative day, both values of VA 1 year after PE were reliably higher in the main group than in the control due to lower number of eyes with posterior capsule opacification.
