Objective To evaluate and compare the effect of burst mode and continuous mode phacoemulsification on hard nuclei cataract.Methods A total of 80 cases (84 eyes) with nuclei density grade of Ⅲ ( according to EMERY classification ) from March 2012 to June 2013 in Department of Ophthalmology,the Second Affiliated Hospital of Baotou Medical College were retrospectively analyzed.They were randomly divided into burst mode group (39 cases,41 eyes) and continuous mode group (41 cases, 43 eyes) .Phacoemulsification surgery and intraocular lens implantation were implemented by using different ultrasonic energy pattern.The actual power ( AP) e,ffective phaco time ( EPT) t,he difference in accumulated energy ( APET) during surgery and corneal edema degree ,visual acuity and corneal endothelial cell number after surgery were recorded.Three-month followu-p was taken after surgery .Independent samples t test was used to evaluate the AP,EPT and APET.The vision and best corrected vision was assessed by chi-square test.Re suluts The AP was (10.12±1.17) in burst mode group and (16.30±1.36) in continuous mode group,and the difference was statistically significant (t=23.362;P <0.05).The EPT was (0.24±0.05) min in burst mode group and ( 0.70 ±0.11 ) min in continuous mode group, and the difference was statistically significant (t=23.727;P <0.05).The APET was (2.43 ±0.53) in burst mode group and (11.45±2.07) in continuous mode group,and the difference was statistically significant (t=27.029;P <0.05).On the first postoperative day,the vision of 8 eyes (19.5%) was≤0.3,17 eyes (41.5%) was 0.4-0.5,16 eyes (39.0%) was≥0.6 in burst mode group while the vision of 25 eyes (58.1%) was ≤0.3, 10 eyes (23.3%) was 0.4-0.5,8 eyes (18.6%)was≥0.6 in continuous mode group,the difference was statistically significant (χ2=13.199;P =0.000);On the third postoperative day, the vision of 0 eye was≤03., 9 eyes(22.0%)was 0.4-0.5, 32 eyes(78.0%) was≥0.6 in burst mode group while the vision of 5 eyes(11.6%) was ≤0.3, 13 eyes(30.2%) was 0.4-0.5, 25 eyes(58.2%) was≥0.6 in continuous mode group,and the difference was statistically significant(χ2=6.543;P=0.038) .But after three months the best corrected visual acuity between two groups showed no statistically significance(χ2=4.385;P>0.05). Corneal edema in burst mode group was significantly lighter than that in continuous mode group on the first and the third postoperative day(χ2=3.562,4.783;P<0.05).Compared with the continuous mode group,the rate of corneal endothelial cell loss was significantly lower in burst mode group one and three months after surgery respectively(χ2=7.308,8.298;P<0.05).Conclusions Compared with the continuous mode,burst mode phacoemulsification caused less corneal endothelial cell damage and faster visual recovery.It is more safe and effective.
