玻璃体切割联合超声乳化治疗晶状体脱位

目的：探讨玻璃体切割联合玻璃体腔内超声乳化治疗脱入玻璃体腔内的晶状体的临床疗效。

方法：回顾性研究玻璃体切割联合高能量(80%～100%)、高负压(200～500mmHg)玻璃体腔内超声乳化治疗的23例晶状体脱位入玻璃体腔患者的资料，观察术前和术后的最佳矫正视力及并发症发生情况。

结果：脱位于玻璃体腔的晶状体23例均通过该方法顺利取出，无与手术有关的并发症发生。平均随访18mo。术前最佳矫正视力3.3～4.2，术后最佳矫正视力3.7～4.9，两者相比，差异有统计学意义(t=-11.244， P=0.000)。

结论：经睫状体平坦部玻璃体切割联合玻璃体腔内超声乳化治疗脱入玻璃体腔内的晶状体是一种有效、安全的方法。

Vitrectomy combined with intravitreal phacoemulsification to treat dislocated lens into the vitreous cavity

AIM: To investigate the clinical effects of vitrectomy combined with intravitreal phacoemulsification to treat dislocated lens into the vitreous cavity.

METHODS:Retrospective study of 23 cases patient's data, whose lens were dislocated into the vitreous cavity were treated by vitrectomy combined high-energy(80%-100%), high negative pressure(200-500mmHg)intravitreal phacoemulsification. We observed the best-corrected visual acuity preoperative and postoperative and complications.

RESULTS:Twenty-three cases of dislocated lens into the vitreous were removed successfully by this method, with no surgery-related complications. The mean follow-up period was 18 months. Preoperative best-corrected visual acuity ranged from 3.3 to 4.2, and postoperative best-corrected visual acuity ranged from 3.7 to 4.9. There was a significant difference(t=-11.244, P=0.000).

CONCLUSION:Pars plana vitrectomy combined with intravitreal phacoemulsification to treat dislocated lens into the vitreous cavity is an effective and safe method.
