AIM: To explore the application of cornea scleral limbus incision(SICS+IOL)in the transformation from the operation of small incision to the surgery of ultrasonic cataract phacoemulsification.

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.
