Abstract Details

Purpose:

To 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.

Setting:

Consecutive, comparative cohort study.

Methods:

96 eyes of 64 patients with grade IV hard nucleus cataract were assigned to 1 of the 2 groups (49 CAPPS and 47 FLACS). Postoperative follow-up was 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), intraoperative and postoperative complications.

Results:

The 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. ECD value decreased at each follow-up visit and did not return to the preoperative level; FLACS resulted in greater endothelial cell loss than CAPPS did. CCT increased immediately after the surgery, and decreased thereafter. The mean CCT value returned to 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.

Conclusions:

Because of its efficacy and cost effectiveness, CAPPS is worthy of being promoted and applied in the future clinical work.
