Femto-laser assisted phacoemulsification of cataract combined with non-penetrating deep sclerectomy
The article presents clinical and functional results of femto-assisted phacoemulsification of cataract combined with nonpenetrating deep sclerectomy with Xenoplast drainage implantation. The procedure was performed on 45 eyes (42 patients) 65-85 years of age with different stages of POAG. In all cases the following examinations were performed: computer perimetry, optic disk retinal tomography, corneal-compensated pressure (IOP CC), pressure equal to Goldman IOP (IOP G) and corneal hysteresis (CH) with the ORA device (Reichert). All examinations were performed before operation and 1, 3, 6 months, 1, 2, 3, and 4 years after the operation. By the end of the 4<sup>th</sup> year, the level of normalized IOP without hypotensive medication was observed in 40.9% of all cases. 58.1% patients had to use 1.7±0.8 medications. Statistically significant increase of CH was 8.8±1.7 mm Hg compared with the same parameter before operation. These data indicate normalization of biomechanical parameters of cornea-scleral capsule of the eye in the long-term post-operation period. Stabilization of glaucoma process according to perimetry and structural parameters was observed in 34 patients, 35 eyes (77.8%, p=0,001). These results show that femto-assisted phacoemulsification combined with non-penetrating deep sclerectomy with Xenoplast drainage implantation is statistically effective method of IOP normalization and stabilization of glaucoma process, decreasing the medication load compared with pre-operation level.
