To analyze the results of femtosecond laser-assisted cataract surgery (FLACS) and conventional phacoemulsification cataract surgery (CPCS) in patients with 1-2 degree lens subluxation.
The follow-up involved 86 patients (89 eyes). The 1 group comprised 34 patients (35 eyes) that underwent FLACS; the 2 group included 52 patients (54 eyes) who underwent CPCS.
At day four of the follow-up central corneal thickness was significantly lower after FLACS (p=0.024), but the difference did not remain statistically reliable by 1.5 months after the surgery. At discharge day and 4 months after the surgery uncorrected visual acuity (UCVA) after FLACS reliably exceeded UCVA of the 2 group patients (p=0.00) with mean UCVA being 0.61±0.29 and 0.42±0.25 respectively. Internal higher order aberrations (HOA) in 5.0 mm zone in the 1 group decreased by 4 times and amounted to 0.236±0.06 μm, in the 2 group increased by 4.1 times and was 4.606±8.16 μm; the difference between the groups was statistically significant (p<0.001). Mean endothelial cells density after FLACS was 2551.91±321.55 cells/mm, after CPCS - 2352.35±436.68 cells/mm (p<0.005). Complications after FLACS included 2 cases (5.71%) of posterior capsular rupture and 1 case (2.8%) of post-op corneal edema; patients after CPCS had 6 (11.1%) and 12 (22.2%) complication cases respectively.
FLACS is the safer and more effective surgery choice for patients with 1-2 degree lens subluxation in comparison with CPCS; it decreases the risk of possible complications and provides faster postoperative rehabilitation.
分析飞秒激光辅助白内障手术（FLACS）和传统超声乳化白内障手术（CPCS）在1-2度晶状体半脱位患者中的手术效果。
随访86例患者（89只眼）。第1组包括34例（35只眼）接受FLACS手术的患者；第2组包括52例（54只眼）接受CPCS手术的患者。
随访第4天时，FLACS术后中央角膜厚度显著降低（p=0.024），但术后1.5个月时该差异不再具有统计学意义。出院时及术后4个月，FLACS术后的未矫正视力（UCVA）可靠地超过第2组患者的UCVA（p=0.00），平均UCVA分别为0.61±0.29和0.42±0.25。第1组5.0 mm区域内的内部高阶像差（HOA）降低了4倍，为0.236±0.06μm，第2组增加了4.1倍，为4.606±8.16μm；两组间差异具有统计学意义（p<0.001）。FLACS术后平均内皮细胞密度为2551.91±321.55个/mm，CPCS术后为2352.35±436.68个/mm（p<0.005）。FLACS术后并发症包括2例（5.71%）后囊破裂和1例（2.8%）术后角膜水肿；CPCS术后患者分别有6例（11.1%）和12例（22.2%）并发症。
与CPCS相比，FLACS是1-2度晶状体半脱位患者更安全、更有效的手术选择；它降低了可能并发症的风险，并提供了更快的术后康复。
