Abstract Details


To compare visual and refractive outcomes between femtosecond laser-assisted cataract surgery (FLACS) and conventional phacoemulsification cataract surgery (CPCS).


Baskent University Faculty of Medicine, Department of Ophthalmology, Ankara, Turkey.


In this prospective comparative study, visual and refractive results of eyes undergoing FLACS and CPCS were compared. The mean absolute error (MAE) was defined as the average of the absolute value of the differences between the actual and predicted spherical equivalences of the postoperative refractive error. Independent t test was used to compare the between-group difference in MAEs calculated by the Holladay 2 formula.


A total of 191 eyes of 166 patients underwent cataract surgery. There were 99 eyes in the FLACS group and 92 eyes in the CPCS group. There was no significant difference in the preoperative (0.46 in FLACS group vs. 0.42 in CPCS group; p=0.56) and postoperative (0.96 in LCS group vs. 0.93 in PCS group; p=0.25) mean Snellen BCVA between groups. The MAE was 0.38 vs 0.39 (p=0.42) in FLACS and CPCS groups respectively.


Both groups had perfect visual outcomes with Snellen BCVAs close to 1.0. FLACS yielded slightly less deviation from the target refraction when compared to standard phacoemulsification cataract surgery at the end of the first postoperative month. However, this difference was not statistically significant.
