Despite more than a decade of use and hundreds of published papers, there is still some controversy as to the potential advantages and disadvantages of using a femtosecond laser to assist in parts of cataract surgery. This paper is important because it is a prospective, randomized, single-center trial with experienced surgeons and patients who did not have to pay for any aspect of the cataract operation. The authors found no differences in the vision, refractive outcomes, adverse events or even patient reported measures whether or not the femtosecond laser was used. The only difference in the group was in regards to astigmatic relaxing incisions, however the mean corneal astigmatism was 1.4 diopters and a toric IOL would have likely performed much better in this setting. For most experienced surgeons there is no benefit to using the femtosecond laser, however for those who find it challenging to create a capsulorhexis or chop the nucleus, the laser can produce more consistent results in their hands.
