AlM: To evaluate the application of phacoemulsification of different nucleus density using ozil and traditional mode.METHODS: A total of 89 eyes (72 patients ) ( visual acuity was of 0. 6 and above after 1mo follow - up) of different nucleus density level (LOCS Ⅱ criteria grade Ⅲ 46 eyes, grade Ⅳ and more 43 eyes ) were randomly assigned into 2 groups: ozil group (group A), grade Ⅲ 22 eyes (torsional energy 80% lP on);grade Ⅳ and more 17 eyes (torsional energy 100% lP on); Traditional mode group(group B), grade Ⅲ 24 eyes (energy 50% ), grade Ⅳ and more 26 eyes (energy 60% ~ 70% ) . All surgeries were performed by the same experienced surgeon,who use the chop to split the nucleus in the application of phacoemulsification. lntraoperative parameters were total equivalent pawer ( TEP ), cumulative dissipated energy ( CDE ) and effective phaco time ( EPT ) and surgical complications. The effectiveness of the two modes in dealing with hard - core cataract phacoemulsification were compared.RESULTS: GradeⅢ nucleus dealing: TEP of ozil group was significantly higher than that of the traditional mode group [(24.58±7.78)% vs (13.84±1.97) %]and EPT of ozil group was significantly lower than that of the traditional mode group (50. 59±14. 73 s vs 60. 19±9. 04 s, P<0. 05). CDE showed no difference between two groups [(13.12±6.03)% vs (13.38±2.85)]. Grade Ⅳ and more nucleus dealing: CDE [( 34. 10 ± 13. 48 )%] and EPT (104. 64±32. 4s) of the ozil group was higher than CDE [(30. 31 ± 13. 48)%] and EPT (93. 01 ± 41. 01s) of the traditional mode group, but there were no difference between two groups. Obstacles in the needle of phacoemulsification surgery: ozil group 4/17, traditional mode group 2/26 (χ2=2. 16, P=0. 14).CONCLUSlON: Bothozil and traditional mode can deal with all kinds of nucleus effectively and safely. Ozil mode is more efficacy and quick deal in gradeⅢnucleus. With the increase of nucleus hardness, the traditional mode still have the advantage of high efficiency and no obstacle to dealing patients with grade Ⅳ and more nucleus. Choose according to different nuclear hardness ultrasonic model can improve the operation efficiency and security.
