Silicone and poly(methyl methacrylate) (PMMA) intraocular lenses from Allergan Medical Optics were implanted in the posterior chamber of 96 cataract patients with small or standard incisions following phacoemulsification. Significantly less keratometric cylinder (astigmatism) and better uncorrected visual acuity were observed during the six week postsurgical follow-up in the patients who received the small incision silicone lens than in those who received the standard PMMA lens.
将爱尔康医疗光学公司生产的硅胶和聚甲基丙烯酸甲酯（PMMA）人工晶状体植入96例白内障患者的后房，这些患者在超声乳化术后采用小切口或标准切口。在术后六周的随访中，接受小切口硅胶人工晶状体的患者角膜散光明显减少，未矫正视力也优于接受标准PMMA人工晶状体的患者。
