Abstract： Objective To investigate the visual quality of patients with acute primary angle closure glaucoma(APACG)combined with cataract undergo implantation of single focus intraocular lens(SIOL)and multifocal intraocular lens(MIOL)after cataract ultrasonic emulsification in binoculus respectively.Methods The clinical data of 28 patients(56 eyes)with binocular APACG combined with cataract were retrospectively analyzed.For 28 APACG combined cata-ract patients(56 eyes),the diagnosis of onset eyes were acute phase or chronic phase of APACG combined cataract,these eyes underwent PEI+GSL and were implanted SIOL,while the diagnosis of the contralateral eyes were preclinical APACG combined cataract,and these eyes underwent PEI and were implanted MIOL.The uncorrected distant visual acu-ity(UDVA),uncorrected intermediate visual acuity(UIVA),uncorrected near visual acuity(UNVA),intraocular pres-sure,defocus curve,contrast sensitivity(CS)and the quality of vision questionnair(QoV)score and glass independence rate of the patients were assessed at 3 months after surgery.Results Three months after surgery,the UDVA of onset eyes in APACG combined cataract patients were(0.48±0.33)and contralateral eyes were(0.12+0.11),which were significantly higher than those before(all P＜0.01);the UDVA,UIVA and UNVA in contralateral eyes and binocular were all superior to the onset eyes after surgery(all P＜0.05),the intraocular pressure of onset eyes were significantly lower than before(P＜0.01).After surgery,the contralateral eyes and binocular defocus curve of APACG combined cat-aract patients showed bimodal shape,at any distance,binocular defocus curve was above the contralateral eyes.Under the photopic and scotopic condition,the CS at spa-tial frequencies of 3 c/d,6 c/d,12 c/d and 18 c/d in con-tralateral eyes and binocular were higher than those in on-set eyes(all P＜0.05);under pho topic condition,CS at 12 c/d and 18 c/d were higher in binocular than those in contralateral eyes,under scotopic condition,CS at 6 c/d,12 c/d and 18 c/d were higher in binocular than those in contralateral eyes(all P＜0.05).28.57％(8/28)of patients had obvi-ous symptoms of glare and serious difficulty focusing after surgery,92.86％(26/28)of the patients did not need to wear glasses.Conclusion APACG combined with cataract undergoing implantation of SIOL and MIOL after cataract ultrasonic emulsification in binoculus can reduce intraocular pressure while providing better postoperative binocular visual acuity and increasing glass independence rate.
