PURPOSE To compare intraocular lens (IOL) tilt and decentration after Nd:YAG laser posterior capsulotomy in eyes that had femtosecond laser-assisted capsulotomy versus manual capsulorhexis. SETTING Ekol Eye Hospital, Izmir, Turkey. DESIGN Retrospective case series. METHODS Intraocular lens decentration and angle of tilt were measured using a Scheimpflug camera before and 1 month after Nd:YAG capsulotomy. RESULTS Eighteen eyes had a femtosecond laser-assisted capsulotomy and 25 eyes a manual capsulorhexis. The mean age was 58.2 years ± 10.2 (SD) (range 44 to 69 years) and 60.6 ± 8.3 years (range 45 to 70 years), respectively. Before capsulotomy, the angle of tilt and decentration at both meridians did not differ significantly between the 2 groups (P > .05). After capsulotomy, the angle of tilt was significantly decreased in both groups (femtosecond: vertical 1.5 degrees and horizontal 1.2 degrees; manual: vertical 1.1 degrees and horizontal) and decentration was significantly increased (femtosecond: vertical 0.085 mm and horizontal 0.096 mm; manual: vertical 0.2 mm and horizontal 0.2 mm) at both meridians (P < .05). After capsulotomy, all tilt and decentration parameters were significantly different between the 2 groups (P < .05) except decentration on the horizontal meridian (P = .669). CONCLUSIONS Nd:YAG posterior capsulotomy performed after femtosecond laser-assisted capsulotomy resulted in better mechanical stability of the IOL. This suggests that a femtosecond laser-created capsulotomy better maintains a proper IOL position. Although the differences were statistically significant, the tilt and decentration values were small and might not be clinically significant.

Nd:YAG激光后囊切开术后人工晶状体倾斜和偏心:飞秒激光撕囊术与手动撕囊术。

目的比较Nd:YAG激光后囊切开术与人工撕囊术与人工飞囊术后眼睛的人工晶状体(IOL)倾斜度和偏心率。地点土耳其伊兹密尔Ekol眼科医院。设计回顾案系列。方法Nd:YAG囊切开术之前和之后1个月,使用Scheimpflug相机测量人工晶状体的偏角和倾斜角度。结果18眼接受飞秒激光辅助切囊手术,25眼接受人工囊撕开术。平均年龄分别为58.2岁±10.2(SD)(范围为44至69岁)和60.6±8.3岁(范围为45至70岁)。切囊术前,两组经络的倾斜角度和偏心角度在两组之间均无显着差异(P> 0.05)。开囊手术后,两组的倾斜角度均显着降低(飞秒:垂直1.5度和水平1.2度;手动:垂直1.1度和水平),偏心度显着增加(飞秒:垂直0.085毫米,水平0.096毫米;手动:垂直0.2毫米和两个子午线的水平0.2毫米)(P <.05)。切囊后,除水平子午线上的偏心度(P = .669)外,两组之间的所有倾斜和偏心参数均存在显着差异(P <.05)。结论Nd:YAG飞秒激光辅助囊切开术后后囊切开术可改善人工晶体的机械稳定性。这表明飞秒激光开囊切开术可以更好地保持适当的IOL位置。尽管差异具有统计学意义,
