Abstract Details


To evaluate balanced salt solution volume, energy and phacoemulsification time for grid pattern lens fragmentation during femtolaser-assisted cataract surgery (flacs) without energy used in brazil.


Tranjan Centro Oftalmologico Sao Paulo Brazil


: Randomized prospective study of 104 eyes (69 patients) that underwent cataract surgery divided in two groups: - Group I (n=52), FLACS without energy - USFREE surgery with grid pattern lens fragmentation and lens aspiration without ultrasonic emulsification; - Group II (n=52), TRADITIONAL PHACO surgery. BSS volume, emulsification time, energy (CDE) and endothelial cell count were compared in both groups.


GROUP 1 - USFREE The mean age was 65,99 (48 - 77). The mean aspiration time recorded was 169,29 seconds (118 - 304) US - CDE were zero in all cases. The mean fluid usage was 55,67ml (43 - 85. GROUP 2 - TRADITIONAL PHACO The mean age was 64,18 (44 - 79). The mean aspiration time recorded was 180,50 (120 - 254) The mean CDE used were 1,30 (0,0 - 2,67). The mean fluid usage was 60,7ml (46 - 85). Best corrected visual acuity in the first day after surgery were better in the us free group, difference statistical significant. Pachimetry has no difference in bth groups.


Ultrasound free FLACS showed lower surgical time and preserved endothelial cell loss in this study.
