方法：选取我院在2012-02/2013-02接受手术的200例200眼白内障患者，行角巩膜缘切口超声乳化手术，术中如遇不安全因素即改为SICS+IOL术，手术均顺利完成。

结果：顺利实施超声乳化白内障手术者共172眼(86%)，28眼(14%)改为角巩膜缘切口SICS+IOL术，术后视力≥0.5者176眼(88%)，0.1～0.4者22眼(11%)，0.1以下者2眼(1%)。术后均无严重并发症。

结论：在小切口转型超声乳化白内障手术初期时，运用角巩膜缘切口能提高手术的可操作性和安全性，是具有小切口白内障手术经验眼科医生很好的选择方式。

METHODS: Totally, 200 cases(200 eyes)suffered from cataract and accepted surgery in our hospital from February 2012 to February 2013 were selected and undergone the surgery of cornea scleral limbus incision phacoemulsification. As soon as there were anything dangerous occurred during the surgery, we would transform into the surgery of SICS+IOL. All the surgeries were successful.

RESULTS: The actually successful performance of ultrasonic cataract phacoemulsification was of 172 eyes(86%), and 28 eyes(14%)were transformed into the surgery of SICS+IOL. In 176 eyes(88%), the patients' postoperative visual acuity was ≥0.5, in 22 eyes(11%)were 0.1～0.4 and in 2 cases(1%)were <0.1. No serious postoperative complication was observed.

CONCLUSION: In the beginning period of the transformation from operation of small incision to the surgery of ultrasonic cataract phacoemulsification, to adopt the surgery of SICS+IOL can improve the practicability and safety of the surgery, and thus is the best choice for doctors in ophthalmic who are experienced in the cataract surgery of small incision.
