Abstract

PURPOSE

To compare different ultrasound modes used in phacoemulsification surgery in terms of their efficacy and outcomes during and after surgery.

METHODS

A total of 86 patients with cataract diagnosis who underwent phacoemulsification surgery in Fatih Sultan Mehmet Education and Research Hospital Eye Diseases Clinic between November 2006 and February 2008 were included in the study and were prospectively analyzed. Patients were randomized into 3 groups based on the phacoemulsification mode to be used (burst, pulse, and linear mode).

RESULTS

Mean phacoemulsification time was 40.32+/-33.14 seconds, ultrasound time was 19.94+/-9.10 seconds, and effective ultrasound time was 20.16+/-16.57 seconds in Group I; mean phaco time was 79.90+/-65.52 seconds, ultrasound time was 15.30+/-5.74 seconds, and effective ultrasound time was 39.95+/-32.76 seconds in Group II; and mean phaco time was 75.75+/-50.56 seconds, ultrasound time was 11.65+/-2.91 seconds, and effective ultrasound time was 37.87+/-22.89 seconds in Group III. Central corneal thickness measurements with pachymetry were 586.61+/-46.86 microm on day 1, 555.54+/-39.31 microm at week 1, 543.29+/-33.88 microm at month 1, and 543.29+/-33.88 microm at month 3 in Group I; 549.83+/-49.18 microm on day 1, 530.03+/-46.42 microm at week 1, 524.32+/-45.76 microm at month 1, and 521.32+/-45.26 microm at month 3 in Group III; and 572.91+/-39.12 microm on day 1, 545.91+/-32.67 microm at week 1, 537.70+/-29.77 microm at month 1, and 534.04+/-28.64 microm at month 3 in Group III.

CONCLUSIONS

Phacoemulsification power should be kept at minimum in order to induce minimal trauma and to achieve early rehabilitation.

摘要

目的

比较白内障超声乳化手术中不同超声模式在手术期间及术后的疗效和结果。

方法

纳入2006年11月至2008年2月在法提赫·苏丹·穆罕默德教育与研究医院眼科疾病诊所接受超声乳化手术的86例白内障患者，并进行前瞻性分析。根据所使用的超声乳化模式（爆破模式、脉冲模式和线性模式）将患者随机分为3组。

结果

第一组平均超声乳化时间为40.32±33.14秒，超声时间为19.94±9.10秒，有效超声时间为20.16±16.57秒；第二组平均超声乳化时间为79.90±65.52秒，超声时间为15.30±5.74秒，有效超声时间为39.95±32.76秒；第三组平均超声乳化时间为75.75±50.56秒，超声时间为11.65±2.91秒，有效超声时间为37.87±22.89秒。第一组第1天使用测厚仪测量的中央角膜厚度为586.61±46.86微米，第1周为555.54±39.31微米，第1个月为543.29±33.88微米，第3个月为543.29±33.88微米；第三组第1天为549.83±49.18微米，第1周为530.03±46.42微米，第1个月为524.32±45.76微米，第3个月为521.32±45.26微米；第三组第1天为572.91±39.12微米，第1周为545.91±32.67微米，第1个月为537.70±29.77微米，第3个月为534.04±28.64微米。
