Abstract Details
Purpose:
To compare the efficacy and safety of femtosecond laser-assisted cataract surgery (FLACS) with conventional cataract surgery (CCS).
Setting:
Department of Ophthalmology, Goethe-University, Frankfurt am Main, Germany.
Methods:
We systematically searched PubMed, Cochrane Library, and EMBASE for studies comparing FLACS and CCS. Outcomes were efficacy and safety parameters. The effect measures were weighted mean differences or odds ratios with 95% confidence intervals. A total of 73 studies (25 randomized controlled, 48 observational) with a total of 12,769 eyes undergone FLACS and 12,274 eyes undergone CCS were included.
Results:
In eyes treated with FLACS, uncorrected and corrected distance visual acuity and spherical equivalent after 1-3 months (P=0.04, P=0.005, and P=0.007) and mean absolute prediction error after 1 week (P=0.02) were better, total and effective phacoemulsification time were shorter (P<0.001 respectively), cumulative dissipated energy was less (P<0.001), circularity was more accurate (P<0.001), central corneal thickness after 1 day was less (P<0.001), and endothelial cell loss after 3 months was less (P<0.001) compared to CCS. Anterior capsule ruptures occurred more often with FLACS. No significant difference in other areas was found.
Conclusions:
FLACS has a comparable advantage and disadvantage profile to CCS. Complications occur rarely with both procedures. Less required ultrasound energy, and thus less injury to ocular tissues leads to better medium-term results after FLACS. Especially patients with low endothelial cell density and dense cataract could benefit from the laser procedure.
