原位超声乳化白内障吸除术

Cataract extraction by phacoemulfication in situ

摘要: 35例37眼,核硬度为Ⅰ~Ⅱ级16眼,Ⅲ级15眼,Ⅳ级6眼,巩膜隧道切口,原位超声乳化晶体核,超声能量设定60%~80%,超声乳化时间45s~3min45s(平均1min52s),植入5mm×6mm椭圆形人工晶体。结果:30眼(81.1%)原位超声乳化成功,术后1周视力 ≥ 0.5和 ≥ 1.0分别为73.0% ≥ 和54.1%;术后1~3月随访视力 ≥ 0.5和 ≥ 1.0者分别为83.8%和70.3%。手术主要并发症为角膜内皮水肿(16.2%)和瞳孔缘损伤。结论:原位超声乳化吸除术联合小切口人工晶体植入术手术时间短,术后散光小,视力恢复快

Abstract: Purpose: To investigate the techique of phacoemulfication in situ for cataract. Methods: 37 eyes of 35 cases were included and the hardness of nucleus were I II degree 16 eyes, III degree 15 eyes, IV degree 6 eyes. Tunnel incision was and in situ phacoemulfication and IOL implantation was performed on all cases. Phaco time was 45"-3’45"（everage 1’52"）. Results: 30 eyes（81.8%） was successful in situ. visual acuity of 0.5 or better and 1.0 or better one week post operation were obtained in 73.0% and 54.1% respectively, and 83.8% and 70.3% 1～3 months follow-up. Conclusion: the technique of phacoemulfication in situ for cataract extraction is worthy to spread due to its short operation time, minimum post operative astigmatism and fast restored visual acuity.
