[Oblique nuclear chopping and nuclear extraction by binding procedure for cataract extraction].
OBJECTIVE
To investigate the effects of oblique nuclear chopping and nuclear extraction by binding procedure (ONCNEB) in cataract extraction.


METHODS
Extracapsular cataract extraction by ONCNEB with foldable IOL implantation was performed in 86 senile cataract cases (97 eyes) by using a line-shaped cataract nuclear chopping apparatus developed by the authors.


RESULTS
In 97 eyes treated with ONCNEB, there was posterior capsular rupture in 1 eye; anterior chamber hemorrhage in 2 eyes; elevated intraocular pressure in 6 eyes; mild corneal edema in 8 eyes which subsided within 5 days. Corrected visual acuity > or = 0.5 was obtained in 78 eyes (80.41%) one week and 91 eyes (93.81%) three months after the operation. Corrected visual acuity was > or = 1.0 in 66 eyes (68.04%) three months after the operation. Mean astigmatism one week and three months postoperatively showed not significant difference as compared with preoperative astigmatism.


CONCLUSIONS
The ONCNEB can solve the problem of implanting foldable IOL through a small incision. This procedure is relatively simple and safe.
