目的 :使用何式钩及劈核技术实施白内障超声乳化手术 ,观察其效果。方法 :采用劈核技术对白内障进行超声乳化手术共 6 72例 (6 84只眼 ) ,观察术后的视力及术中、术后并发症。结果 :术后第一天视力 >0 5者 36 4只眼 (5 3 2 2 % ) ,术后第三天视力 >0 5者 5 2 9只眼 (77 34% ) ,术后三个月视力 >0 5者 6 0 7只眼 (88 71% ) ,其中视力 >0 8者 4 0 1只眼(5 8 6 4 % ) ,术后出现轻度角膜水肿 14 1只眼 (2 0 6 5 % ) ,中度角膜水肿 5 8只眼 (8 4 7% ) ,均在术后第 3天到 1周内恢复。结论 :劈核技术利用机械力与超声能量相配合缩短了手术时间 ,减少了超声能量的副作用 ,相对简化了超声乳化的难度 ;而何式钩设计的优点使得在术中更利于保护囊膜和清除皮质
Objective: To investigate the effect of phacoemulsification and cataract phacoemulsification by using hook-and-loop technique. Methods: A total of 6 72 cases (6 84 eyes) of phacoemulsification with cataract surgery were performed. The postoperative visual acuity and intraoperative and postoperative complications were observed. Results: The first day after operation, the visual acuity was> 0.05 in 364 eyes (53.22%), the visual acuity was> 0.05 on the third day after surgery in 529 eyes (77.34%), three months after operation The visual acuity was> 0.05 in 607 eyes (88 71%), with visual acuity> 0.8 in 40 eyes (5868%) and mild corneal edema in 14 eyes (206 5%) and moderate corneal edema 58 eyes (84.7%), all recovered within 3 days to 1 week after operation. Conclusion: The split-core technique uses mechanical force and ultrasonic energy to shorten the operation time, reduce the side effects of ultrasonic energy and relatively simplify the difficulty of phacoemulsification. The advantage of the hook-type design makes it more conducive to protecting the capsule and Clear the cortex
