目的探讨小瞳孔状态下超声乳化的手术技巧和注意事项。方法应用非切开瞳孔牵拉扩张法及原位超声乳化碎核等技术对７７例（８３只眼）小瞳孔白内障行超声乳化。结果８３只眼中６６只眼应用单纯非切开瞳孔牵拉扩张法，术后全部瞳孔恢复原状；１７只眼分离粘连机化膜剪除后再牵拉扩张，术后１５只眼基本恢复圆瞳孔，２只眼瞳孔不规则。术后１个月裸眼视力≥０．５者４６只眼（５５．４％），矫正视力≥０．５者７１只眼（８５．５％）。结论非切开瞳孔牵拉扩张法可使小瞳孔白内障术后恢复生理性圆瞳孔，无不良反应。
Objective To discuss the surgical techniques and attention points in phacoemulsification through a small pupil. Method Eighty three cataracts of 77 patients were emulsified by using non cut pupil dilation, cystotome or diathermic high frequency capsulorrhexis. Results The 66 cataracts of 83 eyes were emulsified by means of the above method. After the surgery, all the pupils were recovered to normal size (2 to 3 mm), and none of them were damaged. In 17 eyes, the procedure was performed after separation of synechia and excision of the organized membranes; after the surgery, a round pupil was obtained in 15 cases and an irregular pupil in 2 cases. The visual acuity at postoperative 1 month was ≥ 0.5 in 46 eyes (55.4%) and corrected ≥ 0.5 in 71 eyes (85.5%). Conclusion After phacoemulsification through a small pupil by non cut pupil dilation method, the pupil can be recovered to normal and no unfavorable reaction is seen.
