title: [A comparative analysis of the inclination angle of rigid and soft IOLs with intracapsular fixation].
abstract: Eighty-four eye were examined in 67 patients after phacoemulsification with intracapsular IOL implantation. The patients were shared, with respect to IOL rigidity, between 2 groups: group 1--rigid PMMA lenses and group 2--soft hydrogel and acryl lenses. The inclination angle was evaluated for different lens types by using an elaborated mathematical formula. The lenses had capsular fixation in all cases. The deviation angle ranged from 0.58 to 1.22 degrees. The difference between the inclination angle and ocular visual axis for rigid and soft lenses was statistically reliable (p < 0.05). The inclination angle of the optic axis in case of soft lenses versus rigid lenses was to a greater extent pronounced after 2 months of observation. However, the conclusion is not final due to continuous fibrosis of the capsular sac, which affects dynamically the IOL positioning. Therefore, similar studies will be made after 12-14 months to enable final conclusions.
