非衍射型景深延长型IOL在高度近视并发白内障患者中的临床效果
Clinical effect of non-diffractive extended depth of focus IOL in patients with high myopia complicated with cataract
摘要
Abstract
AIM:To evaluate the postoperative clinical efficacy of non-diffractive extended depth of focus intraocular lens(EDOF IOL)in patients with highly myopic cataract(HMC). METHODS:A retrospective analysis was conducted on the clinical data of patients diagnosed with HMC at the hospital from January 2022 to December 2024.Patients were divided into an observation group[undergoing femtosecond laser-assisted cataract surgery(FLACS)combined with non-diffractive EDOF IOL implantation]and a control group(undergoing FLACS combined with aspheric monofocal IOL implantation)according to the type of implanted IOL.Postoperative visual acuity(LogMAR),visual quality,and patient satisfaction were compared between the two groups. RESULTS:A total of 33 patients(47 eyes)were finally included in this study,including 10 patients(17 eyes)in the observation group and 23 patients(30 eyes)in the control group.The observation group had a median age of 59.0(52.8,63.8)y,with 8 males(13 eyes)and 2 females(4 eyes).The control group had a median age of 56.0(53.5,60.0)y,with 13 males(17 eyes)and 10 females(13 eyes).At 3 mo postoperatively,the best-corrected distance visual acuity(BCDVA)was 0.10(0.08,0.12)in the observation group and 0.20(0.10,0.40)in the control group(P=0.586).However,the best-corrected intermediate visual acuity(BCIVA)[0.10(0.10,0.10)vs 0.50(0.40,0.90),P=0.032]and best-corrected near visual acuity(BCNVA)[0.20(0.18,0.20)vs 0.60(0.45,1.45),P=0.044]in the observation group were significantly better than those in the control group.The defocus curve showed that the uncorrected visual acuity(UCVA)in the observation group was relatively stable within the range of-2.00 to+1.00 D,which was superior to that in the control group.Postoperative questionnaires showed that the spectacle independence rate(76%)and overall satisfaction(88%)in the observation group were significantly higher than those in the control group(10%and 60%,respectively). CONCLUSION:Non-diffractive EDOF IOL significantly improves intermediate and near visual acuity,reduces spectacle dependence,and maintains distance visual acuity by extending the depth of focus,providing better postoperative visual quality and life satisfaction for HMC patients.关键词
