OBJECTIVE: The study was designed to investigate the technique of phacoemulsification in which the lens nucleus is fractured without collapse of nucleus into anterior chamber.
METHODS: Phacoemulsification using in situ nuclear fracture technique with posterior chamber intraocular lens implantation was performed on 55 eyes of 52 patients with senile cataract.
RESULTS: The in situ nuclear fracture technique was successfully completed in 92.72% of all the eyes: the average time of lens phacoemulsification was 2.26 minutes, the rate of vitreous loss was 5.46%, the rate of corneal endothelial cell loss was 12.13%, and one week after the operation, the visual acuities of 0.5 or better were obtained in 72.72% of the cases.
CONCLUSION: The key points of in situ fracture technique by phacoemulsification include selection of softer nucleus, continuous ring-shaped capsulorhexis, complete hydrodissection and fracture of the nucleus quadrant by quadrant.
