目的 讨论从白内障囊外摘除术(ECCE)向超声乳化术(Phaco)转换时面临的问题及转换的方式,报告78例80眼;方法采用单手软核法,双手软核法及双手硬核法,详尽介绍了“水平操作、相对静止”的原则,强调手术过程中的安全性;结果 78例80眼中全部一次乳化成功,后囊膜破裂2眼(2.5％),矫正视力一周内恢复至0.5以上66眼(88.5％),1.0以上6眼(7.5％);结论 渐进性安全过渡法会使超声乳化术的学习曲线变得快捷、安全、容易。 OBJECTIVE: To discuss the problems encountered in the conversion from extracapsular cataract extraction (ECCE) to phaco (Phaco) and the modalities of conversion. Eighty-eight cases (80 eyes) were reported. Methods One-hand soft nucleus method, , The principle of “horizontal operation, relative rest” was introduced in detail. The safety during operation was emphasized. Results All of 78 eyes were successfully emulsified in 80 eyes and 2 eyes were posterior capsular rupture (2.5%). The corrected visual acuity returned to 0.5 66 eyes (88.5%) and 1.0 (6) eyes (7.5%). Conclusion The gradual transitional safety method will make the learning curve of phacoemulsification fast, safe and easy.
