KAANAPALI, Hawaii — A femtosecond laser improved refractive cataract surgery results in liquefaction of the lens, capsulorrhexis and corneal incisions, a surgeon reported here.

At Hawaiian Eye 2011, Michael C. Knorz, MD, reported results of his initial refractive cataract surgical experience with the LensX femtosecond laser (Alcon) on 60 eyes compared with traditional phacoemulsification technique in 60 eyes.

"Capsulorrhexis was perfectly centered and highly reproducible in all femtosecond laser cases, whereas less than 10% of manual rhexis cases achieved a diameter accuracy of ±0.25 mm," Dr. Knorz said.

Liquefaction of the lens resulted in a 46% reduction in phaco power, a 28% decrease in epithelial cell loss compared to the phaco group at 1 month and a reduction in variability in effective lens position, Dr. Knorz said.

"The Alcon LensX femtosecond laser application in liquefaction, capsulorrhexis and corneal incisions was safe and effective," he said.

• Disclosure: Dr. Knorz is a paid consultant for LensX.
