To compare the refractive results among eyes that underwent femtosecond laser anterior capsulotomy (LAC) versus eyes that underwent manually created continuous curvilinear capsulorrhexis (CCC).
Prospective, nonrandomized, masked, clinical trial. Thirty eyes underwent LAC using an automated femtosecond laser; 53 eyes underwent manually created CCC. This was immediately followed by lens fragmentation, phacoemulsification and implantation of an in-the-bag intraocular lens (IOL). Main outcome measure: Deviation from target spherical equivalent (SE) refraction
LAC or CCC, phacoemulsification and IOL implantation were successfully completed in all eyes. The mean (SD) deviation from target spherical equivalent (SE) was -0.18 (0.515) for the femtosecond laser group and +0.41 (0.40) for the conventional CCC group (p=0.001).
Compared to eyes that underwent CCC, the post-operative SE among eyes that underwent LAC was significantly closer to the target refraction. The precisely centered and sized capsulotomy created using LAC may help achieve more consistent effective IOL positioning resulting in smaller deviation from target spherical equivalent.
