Abstract

Purpose : Determine the benefits and challenges of combined femtosecond laser assisted cataract surgery with the Catalys® system (Abbott, Abbott Park, IL) and vitrectomy.

Methods : We retrospectively reviewed eight consecutive cases of combined femtosecond laser assisted cataract surgery with the Catalys® system and vitrectomy by a single surgeon.This study was reviewed and approved by the University of Minnesota Institutional Review Board and Ethics Committee.

Results : This study included 6 eyes of females and 2 eyes of males, with mean age of 69.1±7.2 years, mean pre-operative intraocular pressure of 14.9±3.5 mmHg, and mean logMAR best corrected visual acuity of 0.44±0.26. 25% of eyes had history of occlusive retinal vasculitis, 38% of eyes had history of proliferative diabetic retinopathy, 63% of eyes had diagnosis of epiretinal membrane. All patients completed both portions of the combined procedure. There were no complications from the femtosecond laser portion with the mean vacuum time 163s (range 125-320s). Post-operative findings included intraocular pressure rise on day one that resolved by week one in 25% of the eyes; persistent macular edema in 38% of the eyes (present prior to surgery in 2 of the 3 eyes). The mean intraocular pressure was not significantly different at month one (p=0.52), month three (p=0.55), or month six (p=0.32). There was an improvement in mean logMAR best corrected visual acuity to 0.27±0.26 (p<0.05) at month one, 0.25±0.25 (p<0.05) at month three, and 0.22±0.25 (p<0.05) at month six. Intraocular lens was centered in all cases, and mean manifest refraction spherical equivalent was -0.77±0.89, which was not statistically significantly different than the target spherical equivalent of -0.59±0.63 (p=0.24).

Conclusions : Combined femtosecond laser assisted cataract surgery with the Catalys® system and vitrectomy was not associated with significant complications, with an overall improvement in visual acuity.
