目的：评价超声乳化白内障吸出及折叠人工晶体植入术的疗效。方法：对５６例（６４只眼）老年性、先天性和并发性白内障施行３．２ｍｍ巩膜隧道切口超声乳化及折叠人工晶体植入术。并对术后１周、１个月及３个月视力和散光进行追踪观察。结果：术后１周裸眼或矫正视力≥０．５者占８７．５％，１个月者占９３．８％，３个月以上者占９７．１％。术后１周平均散光为１．４２±０．８９Ｄ，１个月为０．８４±０．６４Ｄ，３个月以上为０．８１±０．１２Ｄ。与同期所做５．５ｍｍ切口超声乳化及ＰＭＭＡ硬性人工晶体植入术组比较，术后１周和１个月散光均小于对照组（Ｐ＜０．０５），术后３个月散光无显著性差异（Ｐ＞０．０５）。结论：３．２ｍｍ切口超声乳化及折叠人工晶体植入术早期视力恢复快，效果好而稳定，角膜散光小，适当的植入方法及慎重选择病例可保证手术效果。
Objective: To evaluate the efficacy of phacoemulsification and foldable intraocular lens implantation. Methods: 3.2 mm scleral tunnel incision phacoemulsification and foldable intraocular lens implantation were performed on 56 cases (64 eyes) of senile, congenital and complicated cataract. Visual acuity and astigmatism were tracked at 1 week, 1 month and 3 months after operation. Results: One week after operation, naked eyes or corrected visual acuity≥0.5 accounted for 87.5%, one month accounted for 93.8%, and those who over three months accounted for 97.1%. The average postoperative astigmatism was 1.42 ± 0.89D at 1 week, 0.84 ± 0.64D at 1 month and 0.81 ± 0.12D at 3 months. Compared with 5.5 mm incision phacoemulsification and PMMA hard intraocular lens implantation at the same period, the astigmatism at 1 week and 1 month after operation was less than that in the control group (P <0.05), and there was no significant at 3 months after operation Sex differences (P> 0.05). Conclusion: 3.2mm incision phacoemulsification and foldable intraocular lens implantation early recovery of visual acuity, the effect is good and stable, small corneal astigmatism, appropriate implantation and careful selection of cases to ensure surgical results.
