AIM: To study the small incision cataract extraction and intraocular lens implantation method, prevention skills of complications and clinical effect.

METHODS: Small incision cataract capsule outside removing joint intraocular lens implantation were performed on 842 cases of cataract patients(944 eyes).

RESULTS: Three months after the operation, 347 cases(504 eyes)were paid a return visit. The corrected visual acuity less 0.3 was in 27 eyes(5.4%)among which 2 cases of high myopia leopard grain shape; 0.3 to 0.5 was in 102 eyes(20.2%); 0.5 to 1.0 was in 305 eyes(60.5%); above 1.0 was in 70 eyes(13.9%).

CONCLUSION: Small incision cataract capsule outside removing joint intraocular lens implantation can safely deliver nucleus, avoids the expensive operation equipment, and realizes the small incision without suture. Postoperative astigmatism is small, visual acuity recover fast and stably. It conforms to the impoverished area hospital situation.
