背景/ObjectivesTo comparison the safety and efficacy of cystotome-assisted prechop phacoemulsification surgery（CAPPS）and femtosecond laser-assisted cataract surgery（FLACS）in patients with hard nuclear cataract.Subjects/Methods 96眼64例IV级硬核白内障患者被分配到2组中的1组（49例CAPPS和47例FLACS）。分别于术后1天、1周、1个月、3个月、6个月和1年进行随访，观察指标包括超声功率、有效超声乳化时间（EPT）、矫正远视力（CDVA）、内皮细胞密度（ECD）、角膜内皮细胞丢失率（ECL）、中央角膜厚度（CCT）、结果CAPPS组的超声功率和EPT较低（分别为p= 0.03和<0.0001）。两组患者术后CDVA均较术前改善。ECD值在每次随访访视时降低，并且没有恢复到术前水平;与CAPPS相比，FLACS导致更大的内皮细胞损失。CCT在手术后立即增加，之后下降。CAPPS组的平均CCT值在术后3个月恢复到术前水平，而FLACS组的CCT值需要6个月才能恢复到术前水平。结论CAPPS具有较好的疗效和成本效益，值得临床推广应用。
Background/ObjectivesTo compare the safety and efficacy of cystotome-assisted prechop phacoemulsification surgery (CAPPS) and femtosecond laser-assisted cataract surgery (FLACS) in patients with hard nucleus cataract.Subjects/MethodsNinety-six eyes of 64 patients with grade IV hard nucleus cataract were assigned to 1 of the 2 groups (49 CAPPS and 47 FLACS). Follow-up visits were performed at 1 day, 1 week, 1 month, 3 months, 6 months, and 1 year, and the outcome measures comprised ultrasound power, effective phacoemulsification time (EPT), corrected distance visual acuity (CDVA), endothelial cell density (ECD), corneal endothelium cell loss rate (ECL), central corneal thickness (CCT), and intraoperative and postoperative complications.ResultsThe ultrasound power and EPT were lower in the CAPPS group (p= 0.03 and <0.0001, respectively). Patients in both groups gained better CDVA postoperatively. The ECD value decreased at each follow-up visit and did not return to the preoperative level; FLACS resulted in greater endothelial cell loss compared to CAPPS. CCT increased immediately after the surgery and decreased thereafter. The mean CCT value returned to the preoperative level 3 months postoperatively in the CAPPS group, while in the FLACS group, CCT value took 6 months to return to the preoperative level. Miosis was more likely to occur in the FLACS group.ConclusionsDue to its efficacy and cost-effectiveness, CAPPS is worth promoting and applying to clinical work in the future.
