目的:评价福来视(Tetraflex)可调节人工晶状体植入术的临床效果。方法:白内障患者21例30眼行超声乳化手术并植入Tetraflex可调节人工晶状体。20例29眼同年龄白内障患者植入传统单焦点人工晶状体做对照。所有患者术后1d;1wk;1,3mo常规行裂隙灯检查,屈光、裸眼及矫正远视力和近视力检查。术后3mo检查调节幅度及20g/L毛果芸香碱滴眼前后的前房深度。结果:术后两组均可获得良好的裸眼远视力及矫正远视力,Tetraflex组裸眼近视力明显好于传统单焦点组。动态检影法Tetraflex组的调节幅度为2.25±0.35D,单焦点组为0.65±0.25D(P<0.01)。滴20g/L毛果芸香碱后前房深度变浅分别为0.40±0.20mm,0.15±0.11mm,两组差异有显著意义(P<0.01)。结论:Tetraflex可调节人工晶状体是安全有效的,可为患者提供良好的远近视力。

AIM:To assess the clinical outcome after implantation of the Tetraflex accommodating intraocular lens(IOL).METHODS:Thirty eyes of 21 patients with cataract had phacoemulsification implantation of Tetraflex accommo-dating IOL.Twenty nine eyes of 20 age-matched patients with cataract had the same surgery with a conventional monofocal IOL.Patients were examined 1 day,7,30,and 90 days after surgery.All patients had assessments of slit lamp,refraction,uncorrected and best corrected distance and near visual acuity.The amplitude of accommodation,anterior chamber depth(ACD) before and after application of 20g/L pilocarpine were examined 90 days after surgery.RESULTS:Postoperatively,both groups had excellent uncorrected distance acuity,and best corrected distance acuity.The mean uncorrected near visual acuity was significantly better in the Tetraflex group than in the conventional monofocal IOL group.The retinoscopic accomodative range was 2.25±0.35D in Tetraflex group and 0.65±0.25D in monofocal IOL group(P<0.01).The mean ACD shoaling was 0.40±0.20 and 0.15±0.11mm after pilocarpine 20g/L eyedrops.The differences between the two groups was statistically significant(P<0.01).CONCLUSION:The Tetraflex accommodating IOL is safe and effective.It can provide better distant and near visual acuity.
