Clinical Evaluation of Femtosecond Laser-Assisted Cataract Surgery With Multifocal IOL
Narrative Responses:
Purpose
To report the surgical outcomes and safety of femtosecond (FS) laser cataract surgery (LCS) with a multifocal intraocular lens(IOL).
Methods
All 305 eyes undergoing LCS and ReSTOR multifocal IOL (Alcon Laboratories Inc) implantation between May 2012 and April 2013 were included in the study. Cases underwent anterior capsulotomy, lens fragmentation, and corneal incisions with the Alcon/LenSx FS laser (Alcon/LenSx, Aliso Viejo, CA). The procedure was completed by phacoemulsification and insertion of a multifocal IOL. The control group consisted of a retrospective cohort of 321 eyes that underwent conventional phacoemulsification cataract surgery and ReSTOR implantation between May 2011 and April 2012. Visual results and complications were analyzed at 1, 3 and 6 months, postoperatively.
Results
Uncorrected distance visual acuity was 0.91±0.04 and 0.88± 0.08 in LCS and control groups, respectively (P=.462). No significant difference was noted in spherical equivalent refraction and uncorrected near visual acuity between groups. Docking failures happened in 9 cases during femtosecond laser procedure. The causes were narrow fissure in 5 cases, loosening of conjunctival tissue in 2 cases and severe pterygium in 2 cases. Anterior capsule tear happened in 7 cases in LCS group. Fibrotic posterior capsular opacification due to incomplete coverage of anterior capsule over IOL was noted in 2.1% and 8.2% of eyes in LCS and control groups, respectively.
Conclusion
Visual results of laser cataract surgery group was comparable to conventional phacoemulsification group at 6 months follow-up. However, in authors’ experience LCS group showed more stable visual outcome and much less complaint concerning about unwanted side effect of ReSTOR lens.
