AIM: To observe the clinical effect of 3.2mm incision manual fragmentation cataract extraction combined with intraocular lens(IOL)implantation in cataract.

METHODS: The observation group: 78 patients(95 eyes)with senile cataract in our hospital underwent 3.2mm incision and manual extraction combined with IOL implantation in nucleus cataract; the control group: 82 cases(100 eyes)with senile cataract underwent phacoemulsification and foldable IOL implantation. Operation complications and the recovery of postoperative visual acuity were observed.

RESULTS: The patients in the observation group, 2 eyes(2.1%)of posterior capsule rupture, 3 eyes(3.2%)limitations zonule; postoperative range of mild to moderate corneal edema and opacity in 18 eyes(18.9%), within one week of the flare in 22 eyes(23.2%). The control group was in 3 eyes(3.0%)happened posterior capsule rupture, 4 eyes(4.0%)limitations zonule; mild to moderate edema of corneal opacity in 21 eyes(21.0%), within one week of the flare in 26 eyes(26.0%). The two groups were no elastic membrane detachment, anterior chamber hemorrhage, wound leakage and infection. The two groups had no statistically significant difference in complication(P>0.05). The two groups had no statistically significant difference in postoperative visual acuity(P>0.05).

CONCLUSION: 3.2mm incision manual nucleus cataract extraction and IOL implantation operation is safe and convenient, has the advantages of small incision operation, suitable for clinical promotion and popularization.
