目的观察软性白内障折叠式人工晶体植入的临床疗效。方法40例40只眼的40岁以下的软性白内障病人，随机地分成实验组和对照组各20例，分别采取3．2mm和6.2mm的巩膜隧道切口，采用双腔注吸针管抽吸出软性核及皮质后，分别植入折叠式人工晶体和PMMA－体型后房型人工晶体。结果术后视力两组间比较差别有显著性（P＜0．05），术后造成的角膜激光比较同样差异有显著性（P＜0．05）。结论3．2mm切口手术后具有更好的早期视力，更少的角膜散光，更轻的术后并发症，并主张术中应较大量地使用粘弹性物质。
Objective To observe the clinical effect of folding intraocular lens implantation in patients with soft cataract. Methods Forty 40 eyes of 40-year-old soft cataract patients under 40 years old were randomly divided into experimental group and control group of 20 cases. The scleral tunnel incision of 3.2mm and 6.2mm respectively was performed. Soft nucleus and cortex, were implanted folded intraocular lens and PMMA-type posterior chamber intraocular lens. Results Postoperative visual acuity was significantly different between the two groups (P <0.05). Postoperative corneal laser contrast showed the same difference (P <0.05). Conclusion 3.2mm incision surgery has better early vision, less corneal astigmatism, less postoperative complications, and advocated the use of viscoelastic material should be more extensive.
