目的探讨手法碎核白内障摘除折叠式人工晶状体植入术治疗小瞳孔硬核白内障的临床效果。方法对24例（32眼）小瞳孔硬核白内障施行手法碎核白内障摘除折叠式人工晶状体植入术，记录患者术前、术后的视力，手术前后角膜内皮细胞的密度和丢失率，患者术前、术后的散光，并观察手术并发症的发生情况。结果24例（32眼）患者术后视力：1个月后最佳矫正视力0．1～0．3者6眼，视力0．4—0．5者14眼，视力大于0．6者12眼。术前和术后1个月角膜散光分别为：术前角膜的平均散光度为（0．894-0．68）D，术后1个月角膜平均散光度为（0．98±0．51）D，与术前比较，差异无统计学意义（P〉0．05）。术中后囊破裂2眼，术后17眼瞳孔恢复生理圆形，8眼瞳孔直径3—4mm近圆形边缘不整齐，5眼瞳孔散大5～6mm近圆形，2眼瞳孔上移，瞳孔直径较术前均有扩大。结论手法碎核人工晶体植入术治疗小瞳孔硬核白内障不失为一种可选择的、安全、有效、简便、合理、并发症少的手术方法，熟悉手法技巧是必要条件。
Objective To evaluate the outcome manual small-incision cataract surgery（MSICS） with foldable intraocular lens implantation in the treatment of nuclear cataract in patients with small pupil. Methods MSICS and foldable intraoc- ular lens implantation were performed in 24 cases （32 eyes ） of nuclear cataract with small pupil. The preoperative and postoperative visual acuity, astigmatism, epithelial cell density and loss rate in corneal were recorded. The surgical compli- cations were also observed. Results Of 32 eyes in the 24 cases, the best corrected visual acuity of 12 eyes were 〉 0.6, 14 eyes were 0.4 - 0.5, and 6 eyes were 0.1 - 0.3 one month after the operation; The mean refractive astigmatism in- creased from （0.89 -＋ 0.68 ） to （ 0.98 ＋ 0.51 ） after the operation, there was no significant difference （ P 〈 0.05 ）. Intraop- erative posterior capsular rupture occurred in 2 eyes. The pupil returned to round （ 17 eyes ） or similar round （ 13 eyes）, updrawn pupil in 2 eyes. The size of the pupil was enlarged. Conclusion MSICS and foldable intraocular lens implanta- tion for nuclear cataract with small pupil is a selective, safe, effective, simple and reliable therapeutic method with fewer complication.
