Abstract:
Objective To compare the postoperative visual acuity and visual quality of patients implanted with TEC-NIS Symfony ZXR00 intraocular lenses(IOLs)with different reserved diopters.Methods In this retrospective study,72 cataract patients(72 eyes)who underwent surgery at the Cataract Department,Ophthalmology Center,The Second Nor-man Bethune Hospital of Jilin University from March 2022 to February 2023 were included.The cohort consisted of 37 males and 35 females.Patients were divided into two groups:Group A(reserved diopters of 0 D to-0.30 D,38 eyes)and Group B(reserved diopters of-0.50 D to-0.75 D,34 eyes).The uncorrected distance visual acuity,best corrected distance visual acuity,uncorrected intermediate visual acuity,uncorrected near visual acuity(UNVA),defocus curve,modulation transfer function(MTF)value,total higher order aberration(HOA),spherical aberration,coma aberration,trefoil aberra-tion,Visual Function Index-14(VF-14),spectacle independence rate,and adverse optical disturbances were evaluated 3 months postoperatively.Results At 3 months postoperatively,patients in Group A exhibited significantly better uncor-rected distance visual acuity compared to that in Group B(P＜0.05).No statistically significant differences were observed in best corrected distance visual acuity or uncorrected intermediate visual acuity between the two groups(both P＞0.05).Group B demonstrated significantly better UNVA than Group A(P＜0.05).Significant differences in visual acuity were ob-served at diopters of 0 D and-2.0 D in both groups(all P＜0.05).However,no significant differences in visual acuity were found in the remained ranges of diopters(all P＞0.05).At 3 months after the surgery,no significant differences were found in MTF value,HOA,spherical aberration,coma aberration,trefoil aberration,or incidence of adverse optical dis-turbances between the two groups(all P＞0.05).Additionally,at 3 months postoperatively,Group B had higher VF-14 scores and a greater near spectacle independence rate than Group A,but a lower distance spectacle independence rate than Group A(all P＜0.05).Conclusion Patients with a few reserved diopters exhibit better UNVA and higher satisfaction levels.
