目的探讨人工晶体睫状沟缝合固定术在晶体囊内摘除术后、囊外术中囊膜破裂或晶体小带大范围的松解、以及外伤性白内障、晶状体脱位、玻璃体切割术后等无晶体囊膜的患眼中的应用。方法我院1997年1月~2004年8月间采用后房型IOL缝线固定术完成了42例(43眼),均获得满意效果。其中:1.晶体后囊膜破损在2个象限残存后囊膜者,以此为依托将一侧人工晶体襻置于其上,另侧襻睫状沟缝线固定,即“一点固定法”实施了7例。2.因严重外伤或晶体囊内摘除术后而无晶体后囊者,施行双襻睫状沟缝线固定,即“二点固定法”实施了35例(36眼)。结果随访4~54个月,平均随访24个月复查时矫正视力最佳1.2,最低0.2,视力在0.6以上者22眼(占53.6%),视力偏低者多为角膜瘢痕或眼底病变所致。二期植入者术后视力均高于术前最佳矫正视力。眼压均在正常范围。43眼中,术后均无明显并发症发生。结论IOL睫状沟缝线固定术是无晶体囊膜及晶体后囊膜破裂或晶体小带大范围松解的首选。
Objective To investigate the effect of ciliary sulcus suture fixation in intraocular lens extraction (CAG) after intraocular lens enucleation, capsule rupture or a large area of lens strip release, as well as traumatic cataract, lens dislocation and vitreous dissection Capsule in the eyes of the application. Methods A total of 42 cases (43 eyes) were performed with posterior chamber IOL suture fixation in our hospital from January 1997 to August 2004, and satisfactory results were obtained. Of which: 1. Crystal posterior capsule damage in the two quadrants of the residual posterior capsular membrane, which rely on one side of the artificial crystal 襻 placed on it, the other side of the ciliary sulcus suture fixed, that is, “a little fixed method” Seven cases were implemented. 2. Due to severe trauma or intraocular lens enucleation without crystalline posterior capsule, the implementation of double ciliary ciliary suture fixation, that is, “two-point fixation,” the implementation of 35 cases (36 eyes). Results The patients were followed up for 4 to 54 months. The best corrected visual acuity was 1.2, the lowest was 0.2, the visual acuity was 0.6 or more in 22 eyes (53.6%), the average visual acuity was mostly corneal scars or fundus lesions . The second-stage implants had higher visual acuity than the best corrected visual acuity before surgery. Intraocular pressure are in the normal range. 43 eyes, no significant postoperative complications. Conclusion IOL ciliary sulcus suture fixation is the first choice of aphakic capsule and posterior capsule rupture or a wide range of crystal strip.
