To describe the use of the femtosecond laser in complex cataract cases.
Department of Ophthalmology, University of Colorado, Aurora, Colorado, USA.
Retrospective case series.
This was a single-center retrospective review of consecutive complex cataract surgery cases in which the Lensx femtosecond laser was used between October 2012 and February 2015. Complex cases were defined as white cataracts, dense brunescent cataracts, or cataracts in which zonulopathy was identified preoperatively. Outcome measures included an assessment of the capsulotomy, surgical complications, and postoperative corrected distance visual acuity (CDVA).
Thirty-four eyes of 34 patients were included in this study; 27 had white cataract, 3 had dense brunescent cataract, and 6 had zonulopathy (2 of these also had white cataract). Three patients had an incomplete capsulotomy, and 3 had small radial tears in the anterior capsule. Four patients (11.7%) developed posterior capsule tears during phacoemulsification; 1 of these subsequently had pars plana vitrectomy for a retained lens fragment. Twenty-eight (97%) of 29 patients had a postoperative CDVA of 20/40 or better. Three patients were identified with comorbidities that limited postoperative CDVA. One patient developed postoperative cystoid macular edema.
The femtosecond laser was useful in the surgical approach to patients with complex cataracts, especially for the creation of the capsulotomy.

回顾性病例系列。
这是一项在 2012 年 10 月至 2015 年 2 月期间使用 Lensx 飞秒激光进行的连续复杂白内障手术病例的单中心回顾性研究。复杂病例定义为白内障呈白色、浓密棕色或术前发现有悬韧带病变。主要观察指标包括评估囊袋切开术、手术并发症和术后矫正视力（CDVA）。
本研究共纳入 34 例 34 只眼；27 只眼为白内障呈白色，3 只眼为浓密棕色白内障，6 只眼为悬韧带病变（其中 2 只眼也有白内障呈白色）。3 只眼的囊袋切开不完全，3 只眼的前囊有小的放射状撕裂。4 例（11.7%）患者在超声乳化过程中发生后囊破裂；其中 1 例随后因残留晶状体碎片行玻璃体切除术。29 例（97%）患者术后 CDVA 达到 20/40 或更好。有 3 例患者因合并症导致术后 CDVA 受限。1 例患者发生术后囊样黄斑水肿。
飞秒激光在复杂白内障患者的手术治疗中是有用的，特别是在囊袋切开方面。
