Effect of residual corneal astigmatism on visual acuity of patients undergoing regional refractive intraocular lens implantation
摘要
Abstract
Objective To investigate the effect of residual corneal astigmatism on visual acuity after regional refrac-tive intraocular lens(IOL)implantation.Methods A retrospective cohort study was conducted.The medical records and follow-up data of 73 eyes of 57 cataract patients who underwent ultrasound emulsification cataract extraction combined with LENTIS Comfort LS-313 MF15 IOL implantation in the Ophthalmology Department of the Hebei General Hospital from June 2020 to March 2022 were collected.These patients were grouped according to postoperative residual corneal astigmatism:32 patients(40 eyes)with a residual corneal astigmatism of 0.75(exclusive)-1.50 D were taken as the experimental group,and 25 patients(33 eyes)with a residual corneal astigmatism ≤0.75 D were taken as the control group.The uncor-rected distance visual acuity(5 m),uncorrected intermediate visual acuity(80 cm),uncorrected near visual acuity(40 cm),out-of-focus curve,objective visual quality,subjective visual quality,satisfaction degree and lens removal rate of pa-tients in the two groups were recorded 6 months postoperatively.Results The postoperative uncorrected distance visual acuity(logMAR)was 0.10(0.00,0.22),the uncorrected intermediate visual acuity(logMAR)was 0.00(0.00,0.10),and the uncorrected near visual acuity(logMAR)was 0.20(0.10,0.30)and 0.20(0.10,0.20)in the experimental and control groups,with no statistically significant differences(all P＞0.05).The postoperative out-of-focus curves showed that the distance visual acuity of patients with additional spherical equivalent refraction ranged from+2.00 D to-4.00 D in the two groups had no statistically significant difference(all P＞0.05).There were statistically significant differences in to-tal aberration,coma aberration,modulation transfer function and Strehl ratio in the objective visual quality of patients after surgery(all P＜0.05),and there was no statistically significant difference in the total higher-order aberration,spherical ab-erration and cloverleaf aberration(all P＞0.05).There was no statistically significant difference in the subjective visual quality,satisfaction degree and lens removal rate in the two groups(all P＞0.05).Conclusion Residual corneal astig-matism of 0.75 D to 1.50 D after LENTIS Comfort LS-313 MF15 IOL implantation has no effect on higher-order aberration,spherical aberration,and cloverleaf aberration in subjective and objective visual quality,and has an impact on total aberra-tion,coma aberration,modulation transfer function and Strehl ratio in objective visual quality.关键词
