Each of them was stratified according to nuclear density into three subgroups, subgroups I (Soft NC), II (Medium NC), and III (Hard NC). Sextans-softened fragmentation pattern was performed in the FLACS group. Total EFX utilized for nucleus disassembly and removal was recorded by the completion of each surgery.Results: A total of 117 eyes were included in the FLACS group and 133 eyes in the QCP group. No significant difference in EFX was observed between the two groups (P = 0.228). Regarding subgroups, EFX showed no statistically significant difference between FLACS and QCP (P = 0.283) in soft NC. For hard NC, a trend to lower values of EFX in FLACS compared with QCP was found, but without statistically significant difference (P = 0.122). Only in medium NC were significantly lower values obtained in FLACS compared with QCP (P < 0.0001).Conclusion: When compared with QCP technique, FLACS can be used for advantages aside from EFX reduction, including astigmatic keratotomies, accurate sizing, and centration of capsulotomies especially in hard and soft nuclear cataracts. Significant reduction of total EFX with FLACS is most prominent only in medium-density nuclear cataracts.Keywords: phacoemulsification, EFX, FLACS, quick chop, femtosecond laser, cataract surgeryAssaf AHAly MGZaki RGShaaban YMAziz BFDove Medical Pressarticlephacoemulsificationefxflacsquick chopfemtosecond lasercataract surgeryOphthalmologyRE1-994ENClinical Ophthalmology, Vol Volume 15, Pp 1095-1100 (2021)
