Abstract:

Abstract Objective The aim of this study was to assess the safety and surgical results of combined pars plana vitrectomy and femtosecond laser - assisted cataract surgery ( femtophacovitrectomy ) . Material and methods A prospective , non - comparative case series was conducted by selecting patients with cataract and vitreoretinal pathology who underwent femtophacovitrectomy by a single surgeon at the _Hospital Central Militar_ between June 2013 and February 2014 . An evaluation was made of the preoperative characteristics , surgical indications , results , and postoperative complications , with a minimum follow - up of 3 months . Results The study included 35 eyes of 35 patients , of whom 20 ( 57 .1% ) were male . The mean age was 60 .76 ± 4 .2 years . Diagnoses included vitreous haemorrhage ( 19 cases ) , macular hole ( 6 cases ) , epiretinal membrane ( 7 ) , and tractional detachment ( 5 cases ) . The mean best corrected visual acuity was 1 .3 LogMAR before surgery , and 0 .5 LogMAR at 3 - months follow - up ( _P_ < .05 ) . No patient had visual loss . The intra - operative complication was miosis in 14 .28% . In the early postoperative period ( <1 month ) , all had subconjunctival haemorrhage , with moderate corneal oedema in 20% of cases , and only 2 .85% ( one case ) ocular hypertension associated with use of intraocular gas . There were no cases of endophthalmitis . The mean follow - up was 13 .3 months ( 10 - 16 months ) . Conclusions The use of femtosecond laser in phacovitrectomy is a safe and effective alternative , with similar risk of complications in cases of macular pathology , tractional retinal detachment , and/or vitreous haemorrhage .
