Abstract Details


Study, describe and compare endothelial cell loss and morphological changes after femtosecond assisted cataract surgery (FLACS) and conventional phacoemulsification cataract surgery.


Hospital Universitario Donostia ,Gipuzkoa,Spain


100 patients with bilateral cataract were included for surgery, receiving FLACS in one eye and conventional phacoemulsification in the fellow eye. Surgeries were performed with VICTUS Femtosecond Platform(Bausch+Lomb) and Infiniti Vision System(Alcon) followed by Envista(Bausch+Lomb) IOL implantation. A complete ophthalmological examination including endothelial analysis was performed before, 1-day, 1-week, 1-month, 3-months and 6-months after surgery. For a set area, total counted cell number, average(±standard deviation(SD)) cell size(μm2), cell density(cells/mm2) and cell hexagonality(%) are studied. This trial counts with Local Ethics Committee approval and patient informed consent was obtained before inclusion. Statistical analysis was performed with STATA.


In the FLACS group, mean(±SD) preoperative values for total counted number of cells, average cell size, cell density and cell hexagonality were 150,81±26,76, 430,42±75,93, 2351,84±401,48 and 54,6±8,36 respectively.6-month mean(±SD) values were 135,14±32,34, 484,93±112,34, 2160,96±449,28 and 54,76±8,15 respectively. In the phacoemulsification group, mean(±SD) preoperative values for total counted number of cells, average cell size, cell density and cell hexagonality were 150,71±27,58, 434,17±78,51, 2361,95±402,70 and 56,79±8,66. 6-month mean values(±SD) were 136,41±29,43, 481,30±103,84, 2163,20±415,33 and 56,24±8,89 respectively. Postoperative differences in cell number or changes in cell size, cell density or cell hexagonality between FLACS and phacoemulsification groups were not statistically significant (>0.05).


In this series, there are no statistically significant differences in endothelial cell density or cell morphology when comparing the conventional phacoemulsification group with the FLACS groups in any of the visits.
