Усовершенствованная технология факоэмульсификации набухающей катаракты с фемтолазерным сопровождением

Abstract

Purpose. To optimize the technology of femtolaser-assisted intumescent cataract phacoemulsification. Material and methods. Group I included 29 patients (30 eyes) with intumescent mature cataract, who underwent femtolaser-assisted phacoemulsification using a new, advanced technology. Group II included 20 patients (20 eyes), in whom the femtolaser stage was performed using standard technology. In all preoperative parameters, patients in groups I and II were almost identical. The advanced femtocapsulorexis technology included: preoperative assessment of intralenticular pressure, staining of the anterior capsule of the swelling lens with trypan blue, introduction of a high molecular weight viscoelastic into the anterior chamber to balance intraocular and intralenticular pressure, increasing the laser energy up to 10 mJ when performing anterior capsulorhexis. Results. In group I, in 2 eyes there was a non-penetration of the anterior capsule, in one eye in the 30° sector, in the second – in the 45° sector. The leakage of the lens material into the anterior chamber and the floating anterior capsule were not observed in patients of group I. In group II, non-penetration of the anterior capsule was observed in 6 eyes, in the 140–150° sector – in 2 eyes, in the 90° sector – in 3 eyes, in the 180° sector – in 1 eye. A floating anterior capsule was observed in 5 cases. The leakage of the lens material into the anterior chamber was observed in 9 eyes. Conclusion. The advanced technology of femtolaser-assisted intumescent cataract phacoemulsification excludes the leakage of lens material into the anterior chamber and allows performing the anterior capsulorhexis of a given size and shape. Keywords: intumescent cataract, phacoemulsification, femtolaser-assisted, anterior apsulorhexis.
