Femtosecond laser capsulotomy yields accurate, predictable refractive outcomes

ORLANDO, Fla. — Femtosecond laser anterior capsulotomy is more accurate than a manual technique and may offer improved visual outcomes, according to a study presented here.
"The effective lens position is really influenced by a number of factors," Warren E. Hill, MD, said at the American Academy of Ophthalmology meeting. "The main surgical influence is the capsular opening for the effective lens position of the IOL. Femtosecond laser capsulotomy provides an incremental improvement in refractive outcomes."
The study included 249 patients who underwent laser capsulotomy with or without femtosecond laser lens fragmentation. A control group comprised 123 eyes that underwent manual capsulorrhexis and laser lens fragmentation. Both groups underwent identical phacoemulsification procedures and received the same IOL implant.
The primary outcome measure was spherical equivalent at 6 months postop.
Study results showed that mean deviation from targeted spherical equivalent was 0.39 D in the laser capsulotomy group and -0.41 D in the manual capsulorrhexis group. Outcomes were within 0.5 D of intended spherical equivalent in 78.7% of eyes in the laser capsulotomy group and 53.8% of eyes in the manual capsulorrhexis group, Dr. Hill said.
