目的 :探讨白内障晶体半脱位超声乳化的手术技术要点及手术技巧。方法 :对 17例 17眼白内障晶体半脱位的患者行白内障超声乳化吸出联合后房型囊袋内人工晶体植入手术 ,并对手术技术的要点及技巧进行了研究。结果 :术后 14例前房反应与正常超声乳化相同 ;3 0天视力大于或等于 0 .8者 10例 ,大于或等于 0 .5者 13例 ;矫正视力 1.0者 11例 ,大于或等于 0 .5者 15例 ;人工晶体位于中央者 13例 ;人工晶体偏心 4例 ;术后继发青光眼 3例。结论 :对白内障晶状体半脱位行小切口超声乳化吸出联合囊袋内后房型人工晶体植入手术 ,术后并发症少 ,视力恢复好 ,为此类病人的最佳手术方法。
Objective: To investigate the surgical techniques and surgical technique of phacoemulsification for cataract induced by subluxated crystals. Methods: Seventeen patients with phacoemulsification and posterior chamber intraocular lens implantation were treated with phacoemulsification combined with posterior chamber intraocular lens implantation in 17 patients with phacoemulsification. The main points and techniques of surgical technique were studied. Results: Fourteen cases had the same anterior chamber reaction as the normal phacoemulsification. Ten cases had visual acuity greater than or equal to 0.8 on day 30, 13 cases of greater than or equal to 0.5 on average, and 11 cases on corrected visual acuity of 1.0 or greater .5 in 15 cases; intraocular lens in 13 cases; intraocular lens in 4 cases; postoperative secondary glaucoma in 3 cases. CONCLUSION: Posterior chamber phacoemulsification combined with posterior chamber intraocular lens implantation for cataract subluxation is the best surgical method for this kind of patients.
