One hundred fifty-one unilateral cataract patients were randomly assigned to receive either a one-piece Staar AA-4203 silicone intraocular lens inserted through a 3.5 mm incision, an loptex 5 mm x 6 mm oval optic lens inserted through a 5.5 mm incision, or an AMO three-piece modified C-loop 6.0 round optic poly(methyl methacrylate) lens inserted through a 6.5 mm incision. Follow-up was 97% at two days postoperatively and 84% at one week and two months postoperatively. At one week postoperatively, 62% of 3.5 mm incision cases had uncorrected visual acuity of 20/40 or better compared with 33% of 5.5 mm (P < .01) and 43% of 6.5 mm incision cases. At two months postoperatively, 85% of 3.5 mm incision cases had uncorrected visual acuity of 20/40 or better compared with 64% of 6.5 mm (P < .05) and 71% of 5.5 mm incision cases. The 3.5 mm incision cases had significantly less total keratometric cylinder than other cases at all postoperative examinations (P < or = .001) and less surgically induced cylinder at two days and one week post-operatively (P < or = .02). The 5.5 mm and 6.5 mm incision cases did not differ significantly in visual acuity or astigmatism at any examination.
151例单侧白内障患者被随机分配，分别接受通过3.5毫米切口植入的单片式Staar AA - 4203硅酮人工晶状体、通过5.5毫米切口植入的loptex 5毫米×6毫米椭圆形光学镜片或通过6.5毫米切口植入的AMO三件式改良C形环6.0圆形光学聚甲基丙烯酸甲酯镜片。术后两天随访率为97%，术后一周和两个月随访率为84%。术后一周，3.5毫米切口组62%的患者未矫正视力达到20/40或更好，而5.5毫米切口组为33%（P <.01），6.5毫米切口组为43%。术后两个月，3.5毫米切口组85%的患者未矫正视力达到20/40或更好，而6.5毫米切口组为64%（P <.05），5.5毫米切口组为71%。在所有术后检查中，3.5毫米切口组的总角膜散光明显低于其他组（P ≤.001），术后两天和一周时手术引起的散光也较少（P ≤.02）。在任何检查中，5.5毫米和6.5毫米切口组在视力或散光方面均无显著差异。
