PURPOSE: To investigate the effect of combined burst and occlude mode in the treatment of hard nucleus cataract during phacoemulisification.
METHODS: Phacoemulisification with combined burst and occlude mode were performed in forty-eight eyes with senile cataracts with nucleus density at grade III-V.
RESULTS: First day after operation, the uncorrected visual acuity in 25 eyes were from 0.3 to 0.8 (52.08%), and 4 eyes is better than 0.9 (8.34%). One week later, the visual acuity in 30 eyes has reached to 0.3-0.8 (62.25%), and 11 eyes were better than 0.9 (22.92%). The average effective time was (15 +/- 2.50) seconds for grade III nucleus, (35 +/- 5.33) seconds for grade IV nucleus, and (57 +/- 9.12) seconds for grade V nucleus.
CONCLUSIONS: Phacoemulsification with burst and occlude mode was very effective in the treatment of hard nucleus cataract, and was safer. It can decrease phaco power and has little side effect on the ocular tissues.
