One hundred twelve unilateral cataract extraction patients were randomly assigned to receive either a one-piece Staar Model AA-4203 silicone intraocular lens (IOL) implanted through a 3.2-millimeter incision, or a one-piece polymethylmethacrylate IOL implanted through a 6.0-millimeter incision. Follow up was 96% at 1 day postoperatively, 90% at 3 months, and 70% at 1 year. Fifty-three percent of the eyes that received a smaller incision could see 20/40 or better uncorrected at 1 day, as compared with 19% of the eyes that received a 6-millimeter incision (P < .01). At 3 months, significantly more smaller-incision eyes could still see 20/40 or better (P = .03). The smaller-incision eyes also had significantly less surgically-induced astigmatism at both 1 day (P < .01) and 3 months (P = .02), and had significantly less flare (P < .01) and cellular reaction (P = .04) at 1 day.
112名单侧白内障摘除患者被随机分配，分别接受通过3.2毫米切口植入的一片式Staar AA - 4203型硅酮人工晶状体（IOL），或通过6.0毫米切口植入的一片式聚甲基丙烯酸甲酯人工晶状体。术后1天的随访率为96%，3个月时为90%，1年时为70%。接受较小切口手术的眼睛中，53%在术后1天无需矫正视力即可达到20/40或更好，而接受6毫米切口手术的眼睛这一比例为19%（P < 0.01）。在3个月时，接受较小切口手术的眼睛中仍有显著更多比例能达到20/40或更好的视力（P = 0.03）。较小切口的眼睛在术后1天（P < 0.01）和3个月（P = 0.02）时手术引起的散光也显著更少，且在术后1天，眩光（P < 0.01）和细胞反应（P = 0.04）也显著更少。
