Abstract
Background/aimTo compare visual and refractive outcomes, changes in intraocular pressure (IOP), and complications of femtosecond laser-assisted cataract surgery (FLACS) to conventional phacoemulsification surgery (CPS) in paired eyes from the same patients.MethodsThis is a secondary analysis of an intraindividual, randomised, controlled clinical trial including 110 paired eyes from 55 patients that were randomised into either FLACS or CPS groups. Outcomes were recorded at baseline and postoperatively during a 3-month follow-up period.ResultsUncorrected distance visual acuity and corrected distance visual acuity were similar between FLACS and CPS over the follow-up period (p>0.05). The mean absolute refractive error was not significantly different between the two groups at postoperative month 1 (POM1) (0.3±0.2 D in FLACS vs 0.4±0.3 D in CPS, p=0.18) and month 3 (POM3) (0.3±0.3 D in FLACS vs 0.3±0.3 D in CPS, p=0.71). IOP was statistically higher in the FLACS group on postoperative day 1 (20.6±5.7 mm Hg for FLACS and 18.0±4.9 mm Hg for CPS, p=0.01). However, it was similar between the two groups subsequently (p>0.05). Intraoperatively, one case of posterior capsular block syndrome was observed in the FLACS group. Postoperatively, one case of newly developed glaucoma was observed in the FLACS group and one case of retinal tears in the CPS group.ConclusionThe 3-month postoperative refractive and visual outcomes were comparable between FLACS and CPS in paired eyes from the same patients. Complication rate was low in the study population.
