OPTICAL FUNCTIONS OF PATIENTS AFTER OPERATIVE TREATMENT OF CATARACT WITH IMPLANTATION OF VARIOUS MODELS OF MULTIFOCAL INTRAOCULAR LENSES
The article presents a comparison of functional results after implantation of various types of intraocular lenses (IOL) in cataract surgery. Clinical study included 90 cases of patients who underwent cataract surgery. These patients were divided into three groups: the 1<sup>st</sup> group included 30 patients with the monofocal IOL (Miol-2); the 2<sup>nd</sup> group - 30 patients with the bifocal IOL (Miol-Akkord) and the 3<sup>rd</sup> group - 30 persons with the trifocal IOL (Miol-Rekord). Visual acuity, contrast sensitivity function and quality of life were assessed during the follow up period. In the 1<sup>st</sup> group there were significant improvement in the distance visual acuity (0,82±0,02) with near visual acuity and intermediate visual acuity regressing to (0,32±0,05) and (0,25±0,01) respectively. In the 2<sup>nd</sup> group the significant improvement in both distance visual acuity (0,76±0,08) and in near visual acuity (0,64±0,18) was observed, with the intermediate visual acuity regressing (0,45±0,03). The results in the 3<sup>rd</sup> group showed better outcomes in the distance visual acuity (0,74±0,01) and in near visual acuity (0,58±0,06) as well as in intermediate visual acuity (0,6±0,04). After implantation of trifocal IOL, however, there was significant reduction in scopatic contrast sensitivity in patients, “Halo-effects” appearing. Subjective patient satisfaction was high in all study groups. Multifocal lenses provide relative visual independence of the patient compared to monofocal.
