- Abstract: Objective To investigate the impact of the"micro-monovision"approach with ex-tended depth of focus(EDOF)intraocular lens on visual quality in elderly patients with senile cata-racts.Methods A retrospective analysis was conducted on the clinical data of elderly patients with senile cataracts treated from January 2020 to December 2023.Forty-six patients who received trifocal intraocular lens were randomly selected and included in trifocal group,while 53 patients who under-went the"micro-monovision"approach with EDOF intraocular lens were included in EDOF group.Preoperative and 3-month postoperative uncorrected distance visual acuity(UCDVA),uncorrected in-termediate visual acuity(UCIVA),uncorrected near visual acuity(UCNVA)and visual function in-dex(VF-14)scores were recorded for both groups.Defocus,contrast sensitivity(CS)and spectacle independence were also evaluated at 3 months postoperatively.Results At 3 months postoperatively,both groups showed significantly higher UCDVA,UCIVA,UCNVA and VF-14 scores compared to preoperative levels;the UCIVA,UCNVA and VF-14 scores in the EDOF group were significantly higher than those in the trifocal group(P＜0.05).At 3 months postoperatively,both groups a-chieved visual acuity greater than 0.35 at refractive errors from-4.0 D to+2.0 D.The EDOF group achieved visual acuity greater than 0.9 at refractive errors from-1.5 D to+1.5 D,and greater than 0.8 at refractive errors from-2.5 D to-1.5 D.Within the refractive range of 0.5 D to+2.0 D,the EDOF group had better visual acuity than the trifocal group,with more stable visual acuityin the range of-2.0 D to 1.0 D.Under photopic and mesopic conditions,the EDOF group demonstrated significantly higher CS values at different spatial frequencies(3,6,12,18 degree per week)compared to the trifocal group(P＜0.05).Conclusion In elderly patients with senile cat-aracts,the"micro-monovision"approach with EDOF intraocular lens implantation provides superior visual quality andintermediate and near vision compared to trifocal intraocular lens.
