Description
Summary:To present the advantages of performing femtosecond laser-assisted (Alcon-LenSx Inc.) cataract surgery. Cataract surgery was performed with the LenSx femtosecond laser (Alcon-LenSx Inc.) in 50 eyes of 50 patients. The laser was programmed to perform a 4,9-4,5 mm capsulorhexis, a 2,3 mm main corneal incision, two 1,3 mm side-port incisions and either a hybrid-pattern or a cylinder-pattern fragmentation of the nucleus. The evaluated parameters were the capsulotomy, the corneal wounds and the nucleus fragmentation. Phacoemulsification of the nucleus and aspiration of the cortex were performed with the Alcon Centurion Vision System and monofocal, toric and multifocal IOLs were successfully implanted. A continuous, central, curvilinear capsulorhexis was performed in 48 cases, 96% (free-floating capsulotomy). In 2 cases, micro-adhesions were reported and detached with the Utrata forceps. Femtolaser capsulotomy resulted in a complete overlap of the anterior capsule over the IOL optics in all cases. Horizontal decentration was found in 2 cases, 4% and vertical decentration in 1 case, 2%. The main corneal incision was self-sealing in 49 cases, 98%. Sutures were used in 1 case, 2%. The hybrid pattern of nucleus fragmentation was used in 42 cases, 84% and the cylindrical pattern in 8 cases, 16%. The fragmentation was incomplete in one case of white cataract and in one case of traumatic cataract. The main advantages of femtolaser cataract surgery are standardized corneal incisions, perfectly centered, round capsulorhexis, and lens nucleus fragmentation even in eyes with hard cataracts. The laser precision is due to the real time OCT software programs, which cover the whole anterior segment, up to the posterior lens capsule.
