Better refractive results reported with femtosecond vs. manual cataract surgery
WASHINGTON — Femtosecond laser-assisted cataract surgery provides more accurate refractive outcomes than manual surgery, according to a study presented at the American Society of Cataract and Refractive Surgery meeting here.
A retrospective review of more than 2,000 charts compared the refractive outcomes of 225 eyes that underwent cataract surgery with the LenSx femtosecond laser system (Alcon) and 231 eyes that underwent manual cataract surgery.
“The proportion of eyes within 0.5 D of target refraction demonstrates there is a statistically significant difference between the LenSx and the manual group,” Elizabeth Yeu, MD, said.
A total of 94.2% of patients in the LenSx group were within ±0.5 D of the refractive target compared with 83.1% of those in the manual group.
A statistical difference was also observed in the absolute projection error and postoperative uncorrected visual acuity, according to Yeu.
“It does appear, based on this information, that femtosecond laser-assisted cataract surgery can and likely provides more accurate refractive outcomes,” she said. – by Rebecca L. Forand
