Schweitzer C, Brezin A, Cochener B, et al. - Researchers assumed that femtosecond laser-assisted cataract surgery (FLACS) might improve outcomes in cataract surgery compared with phacoemulsification cataract surgery (PCS) despite having higher costs. A participant-masked randomized superiority clinical trial was designed to compare FLACS and PCS in two parallel groups (permuted block randomisation stratified on centres via a centralised web-based application, allocation ratio 1:1, block size of 2 or 4 for unilateral cases and 2 or 6 for bilateral cases). Five French University Hospitals included a sum of 907 individuals (1,476 eyes) aged 22 years or older who were eligible for unilateral or bilateral cataract surgery. Notwithstanding, its excellent technology, femtosecond laser was not higher to phacoemulsification in cataract surgery and, with higher costs, did not give an additional advantage over phacoemulsification for individuals or health-care systems.
