AIM:To compare perioperative parameters of one-handed rotational phacoemulsification technique(one-handed phaco-roll)with each of other two techniques,“Divide et Conquer”and femtosecond laser-assisted cataract surgery(FLACS)METHODS:In this retrospective and comparative cohort study,eyes with uncomplicated cataract(nuclear density grade 2 to 3)treated routinely with one-handed phacoroll(n=23;Group 1)or“Divide et Conquer”(n=23;Group 2)or FLACS(n=23;Group 3)were enrolled.Intraoperative parameters including effective phaco-time(EPt),ultrasound time(USt),aspiration time,surgical time,phacoemulsification(phaco)-power,balanced salt solution(BSS)use,cumulative dissipated energy(CDE)were recorded and compared.Clinical outcomes including best corrected visual acuity(BCVA),corneal endothelial cell density(ECD),endothelial cell loss(ECL),central corneal thickness(CCT)and central macular thickness(CMT),were assessed and compared pre-operatively and at 1mo after surgery.RESULTS:Aspiration and surgical time,and BSS used were lower in Group 1(P<0.01)than other groups.EPt,phaco-power and CDE were lower in Group 1(P<0.05)than Group 2 but not significantly different from Group 3.In Group 1,USt was lower(P<0.05)than Group 2 but higher(P<0.05)than Group 3.BCVA improved in all groups without significant difference between Group 1 and the other ones.No significant differences regarding all post-operative morphologic outcomes(ECD,ECL,CCT,CMT)were reported.No clinical complications occurred.CONCLUSION:One-handed phaco-roll seems to be less time-consuming than“Divide et Conquer”and FLACS and less energy-consuming than“Divide et Conquer”.Furthermore,one-handed phaco-roll seems to have an equal safety profile compared to the other two techniques.
