Femtosecond Laser-Assisted Cataract in Vitreoretinal Surgery

Abstract

Purpose To assess the safety and surgical results of femtosecond laser-assisted phacovitrectomy. Methods Fifteen patients over 50 years of age with coexisting vitreoretinal pathologies and cataract underwent combined femtosecond laser-assisted cataract extraction and sutureless 25-G and 27-G vitreoretinal surgery. Results The indication for surgery was macular hole in 6 patients, epiretinal membrane in 6, vitreous hemorrhage in 2, and retinal detachment in 1. The mean preoperative best-corrected visual acuity (BCVA) was 0.64 ± 0.23 logMAR and the mean postoperative BCVA was 0.19 ± 0.11 logMAR. In 4 patients with epiretinal membrane with corneal astigmatism of 3.35 ± 0.32 D as mean value, a toric intraocular lens (IOL) was implanted: mean residual refractive cylinder was 0.47 ± 0.23 D. Three months postoperatively, mean IOL rotation was 1.64 ± 0.28°. All patients improved their visual acuity. The intraoperative complications of femtosecond laser were 1 subconjunctival hemorrhage, 1 case of miosis, and 1 suction loss. The surgeon was able to maintain a clear view of the retina at all times. After surgery, a better fundus examination was possible with no capsular opacification. Mean follow-up was 6 months. Conclusions Femtosecond laser cataract in vitreoretinal surgery appears a safe and effective technique with potential benefits: the precision and centration of the capsulorhexis may potentially reduce the risk of IOL prolapse into the anterior chamber in gas-filled eyes. Implantation of the toric IOL was effective in reducing preexisting corneal astigmatism and provided good rotational stability and refractive outcome.
