[Small incision extra-capsular cataract extraction with a manual nucleus division technique and intraocular lens implantation].

A 6mm incision extra-capsular cataract extraction (ECCE) with a manual nucleus division technique and intraocular lens implantation was performed on 70 eyes of 66 patients with senile or complicated cataracts. Post-operatively, the visual acuities were 0.5 or better in 76.6% at one week and in 96.4% at three months. The mean post-operative astigmatism was 1.96 +/- 1.08D at one week and 0.92 +/- 0.68D at three months which was less than that in the control group, large incision (10-12mm) ECCE performed in the same period and compared at the same times, respectively (P < 0.001). The technique and instruments of this procedure were described, and its key steps and complications discussed.
