EFFICACY AND SAFETY OF POSTERIOR CAPSULOREXIS USING POBH IN COMPARISON WITH TRADITIONAL IOL IMPLANTATION TECHNIQUE FOR AGE-RELATED CATARACTS

Goal. To evaluate the effectiveness and safety of posterior capsulorexis using primary optical biomechanical fixation (POBH) compared with the traditional technique of implanting an intraocular lens (IOL) into a capsule bag during age-related cataract surgery. Materials and methods. The study was conducted on the basis of the Dagestan Eye Microsurgery Center in the period from September 2023 to October 2024. The study included 20 patients (40 eyes) with age-related cataracts who underwent bilateral cataract removal surgery on one day. The patients were randomly divided into two groups: one underwent surgery using the POBH method, the other underwent traditional IOL implantation. The data was analyzed using a variance analysis of repeated measurements. Results. The maximum intensity of the intraocular flare was higher in the eyes with implanted IOL compared with POBH one hour after surgery, but the differences were leveled by the sixth day and a month later (p>0.04). The duration of surgery and the time of phacoemulsification were statistically equivalent between the groups (p=0.32 for the duration of surgery, p=0.54 for phacoemulsification). Conclusions. POBH is a safe and effective technique for IOL implantation during age-related cataract surgery. It does not increase the duration of surgery and minimizes the postoperative inflammatory response. The use of the POBH method may be recommended to reduce the risk of secondary cataracts and inflammation.
