To compare the shape of the capsulotomy, its change, and its impact on visual quality over 1 year using the femtosecond laser system from the manual technique.
In this two-center cross-sectional study from May 2012 to June 2013, each patient had femtosecond laser-assisted cataract surgery in one eye (FLACS group) and conventional phacoemulsification cataract surgery in the other eye (CPCS group). An evaluation of the capsulotomy was performed using retroillumination slit-lamp photographs at 7 days, 6 months, and 1 year after surgery. Effective lens position (ELP), refractive error, and corrected distance visual acuity (CDVA) were analyzed.
Thirty-three patients were included in the study. Diameters of capsulorhexis were more precise and deviation surfaces were lower in the FLACS group than in the CPCS group at each evaluation (P < .05). Femtosecond laser capsulotomies were less modified over time than manual continuous curvilinear capsulorhexis. No significant differences were observed for CDVA, refractive error, and ELP between groups.
More precise capsulotomy sizing can be achieved with the femtosecond laser compared to continuous curvilinear capsulorhexis. Femtosecond laser capsulotomies are less modified over time but did not improve ELP or visual quality. [J Refract Surg. 2017;33(1):44-49].
使用飞秒激光系统与手动技术比较囊切开术的形状、其变化以及1年内对视觉质量的影响。
在这项于2012年5月至2013年6月开展的双中心横断面研究中，每位患者一只眼睛接受飞秒激光辅助白内障手术（飞秒激光白内障手术组），另一只眼睛接受传统超声乳化白内障手术（传统白内障超声乳化手术组）。在术后7天、6个月和1年时，使用后照法裂隙灯照片对囊切开术进行评估。分析有效晶状体位置（ELP）、屈光不正和矫正远视力（CDVA）。
33例患者纳入研究。在每次评估时，飞秒激光白内障手术组的连续环形撕囊直径更精确，偏离表面更低（P <.05）。与手动连续环形撕囊相比，飞秒激光囊切开术随时间变化的改变更小。两组之间在CDVA、屈光不正和ELP方面未观察到显著差异。
与连续环形撕囊相比，飞秒激光可实现更精确的囊切开术大小。飞秒激光囊切开术随时间变化的改变更小，但并未改善ELP或视觉质量。[《屈光手术杂志》。2017;33(1):44 - 49]
