非球面散光矫正型多焦点人工晶状体在白内障中的临床观察

摘要

AIM: By comparing the aspheric and multifocal Toric intraocular lens and the aspheric intraocular lens in cataract patients,to observe the patients` visual quality,to evaluate the patients` distance visual acuity,near visual acuity,Pseudo-accommodative power,residual astigmatism,the rotational stability of AcrySof IQ Toric Restor intraocular lens (IOLs),contrast the rate of off-distance glass,the rate of off-near glass and patient satisfaction after the implantation of AcrySof IQ Toric Restor IOL in the cataract patients with preexisting corneal astigmatism.METHODS:Carried out in 46 patients (48 eyes) with age-rated cataract who receiving phacoemulsification and implantation of artificial lens in our department during February 2014 to June 2016.All the cases were randomly divided into 2 groups: experimental group: 23 cases (24 eyes),AcrySof IQ ReSTOR Toric IOL was implanted after phacoemulsification;control group: 23 cases (24 eyes),AcrySof IQ was implanted.Uncorrected distance visual acuity (UCDVA) and best corrected distance visual acuity (BCDVA),uncorrected near visual acuity (UCNVA) and best-corrected near visual acuity(BCNVA),Pseudo-accommodative power,residual astigmatism,preoperative and postoperative corneal astigmatism,the rate of off-distance glass,the rate of off-near glass and patient satisfaction were measured at 6mo postoperatively follow-up.RESULTS: BCDVA and BCNVA were not statistically different between the two groups(P0.05),而裸眼远视力、裸眼近视力均有统计学差异(P<0.05).两组患者术后1wk,1、3、6mo的剩余散光差异有统计学意义(P<0.05),术后6mo时两组患者对疗效满意度差异有统计学意义(P<0.05);术后6mo视近视远脱镜率,试验组明显高于对照组,差异有统计学意义(P<0.05).结论:非球面散光矫正型人工晶状体具有良好的近附加和散光矫正,可为患者提高良好的裸眼远视力和裸眼近视力,明显提高患者术后的脱镜率和对疗效的满意度,是白内障术后患者尤其是散光伴有明显视近阅读需求患者的福音.
