Visual, astigmatic, and inflammatory results with the Staar AA-4203 single-piece foldable IOL: a randomized, prospective study.

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.
