Subjective patient satisfaction after implantation of two types of trifocal diffractive IOLs

Abstract

Purpose. To compare quality of life and patient satisfaction in patients after cataract phacoemulsification with implantation of trifocal IOLs ZEISS AT Liza try 839 MP and AcrySof IQ PanOptix using an online computer simulator (Halo & Glare Simulator) and a questionnaire. Materials and methods. The study included 40 patients with senile cataracts who underwent phacoemulsification of cataracts with implantation of trifocal diffractive IOLs. In the postoperative period, patients were questioned to determine subjective satisfaction with the treatment result, according to the results of which the lowest number of points corresponded to the maximum satisfaction. The perception of halo and glare effects was investigated using an online computer simulator (Halo & Glare Simulator), which uses a scale of halo intensity and size from 0 to 100. The simulator classifies halos into three types: T1, T2 and T3. Results and discussion. The mean halo sizes for PanOptix and AT Liza try 839 MP were 31.15±23.88 and 30.14±21.62 (p-value=0.9683), respectively; in terms of halo intensity 34.77±20.38 and 32.43±27.69 (p-value=0.7511), respectively; glare size was 23.46±18.91 and 23.14±9.58 (p-value=0.5785), respectively; glare intensity was 27.31±21.52 and 35.57±8.34 (p-value=0.6055), respectively. The mean values of the sum of points according to the results of the questionnaire survey for PanOptix and AT Liza try 839 MP were 8.46±6.75 and 9.7 ±7.25 (p-value=0.6055), respectively. Conclusion. Our data demonstrate no significant differences in the size and intensity of halo and glare effects, as well as in the sum of scores according to the results of subjective patient satisfaction after implantation of two compared trifocal diffraction IOLs ZEISS AT Liza try 839 MP and AcrySof IQ PanOptix.
