AIM:To evaluate the clinical effect of small incision cataract extraction with a manual nucleus division technique combined with intraocular lens implantation in cataract operation of large quantities.

METHODS: Totally 105 patients(105 eyes)underwent small incision cataract extraction surgery. Visual acuity was observed, eye condition, fundus and intraocular pressure were examined by slit lamp at postoperative 1wk; 1mo.

RESULTS: The visual acuity improved significantly at postoperative 1mo, 89 cases(89 eyes)with better than 0.3(85%), 101 cases(101 eyes)with 0.1 and above(96%). It had short operation time, fewer complications and good anesthetic effect.

CONCLUSION: This operation is suitable for primary hospitals, which visual acuity improved obviously, without serious complications, and economic and feasible.
