Switch to laser cataract surgery optimizes outcomes

Making the switch to laser cataract surgery proved beneficial for one surgeon, who experienced improvements to his LASIK enhancement rate, refractive accuracy, and visual acuity outcomes.

Bloomington, MN-After noticing a decrease in patients seeking an enhancement after implantation of the accommodating IOL (Crystalens AO, Bausch + Lomb), it occurred to Y. Ralph Chu, MD, that the trend coincided with his shift to performing femtosecond laser-assisted cataract surgery. 

Results of a retrospective study comparing cohorts of patients operated on with a conventional manual approach versus using a femtosecond laser (Victus, Bausch + Lomb) confirmed his impression by showing that the LASIK enhancement rate among his accommodating IOL patients fell by almost half, from 11.5% to 5.8%.

In addition, the femtosecond laser group had better refractive and visual acuity outcomes, said Dr. Chu, founder and medical director, Chu Vision Institute, Bloomington, MN.

“Other surgeons I have talked to seem to be noticing similar trends, but those are anecdotal observations and mine is a first retrospective look at my data,” he said, adding that further study with more rigorous analyses is needed.

If the findings can be confirmed, they have clinical importance considering that these premium IOL patients have high expectations for excellent outcomes and a need for LASIK enhancements not only diminishes their satisfaction, but also costs surgeons time and money, he noted.

Dr. Chu compared enhancement rates by identifying 130 eyes with the accommodating IOL before and after he switched to the femtosecond laser procedure. Regardless of the technique, he was targeting a 5.5-mm capsulotomy.

At 3 months after surgery, mean MRSE was -0.95 D for the manual surgery cohort and -0.68 D for the eyes that underwent laser cataract surgery. The proportion of eyes in the two groups with an achieved MRSE within 0.5 D of target was 52.4% and 76.8%, respectively, and their mean distance uncorrected visual acuity was 20/40 and 20/30, respectively.
