目的研究小瞳孔状态下白内障超声乳化的手术技巧和要点。方法采用不切开瞳孔括约肌的瞳孔牵拉扩张法及拦截劈裂技术对46例(52只眼)小瞳孔的白内障行超声乳化。结果52只眼中47只术后瞳孔全部恢复原状,另有5只眼在分离切除机化膜粘连后再行牵拉扩张,术后基本恢复圆瞳孔,术后1个月裸眼视力≥0.5者38只眼(73%)。结论采用非切开瞳孔牵拉扩张可使小瞳孔白内障术后恢复生理性圆瞳孔及术后较好的视力恢复。
Objective To study the surgical techniques and main points of cataract phacoemulsification under small pupil condition. Methods 46 cases (52 eyes) of small pupil cataract were subjected to phacoemulsification by using the pupillary stretch-and-expand method and the interception and cleavage technique without incising the pupil sphincter. Results All the 47 postoperative pupils in 52 eyes were restored to their original shape. In addition, 5 eyes underwent resection and removal of adhesions of the excision machine, and then pulled and dilated. The pupils were recovered after operation. The uncorrected visual acuity ≥ 0.5 at 1 month Only eyes (73%). Conclusion Non-incision pupil stretch can make small pupil cataract recovery physiological circular pupil and postoperative better vision recovery.
