Femtosecond laser-assisted cataract surgery <i>vs</i> traditional phacoemulsification in the treatment of patients with different axial length cataracts

Abstract

AIM: To compare the effectiveness and safety of femtosecond laser-assisted cataract surgery(FLACS)with traditional cataract surgery in cataract patients with different axial lengths.METHODS: Patients with cataract surgery were divided into normal axis group(22mm≤ALRESULTS: The visual acuity of the patients in each group was improved(FLACS: t=8.29, 25.01, 19.23, all Pt=19.61, 18.76, 18.23, all PP=0.24, 0.25, 0.19). The postoperative strehl ratio value increased after operation in all groups expect for PHACO medium and long axis group, but the increase was significant only in normal axis group(P=0.011, 0.007). The corneal endothelial counts in the FLACS group were significantly lower than those before the operation(PPP>0.05).CONCLUSION: Both traditional cataract surgery and femtosecond laser-assisted cataract surgery can effectively improve the BCVA in various types of axis. Both surgical methods will cause damage to the corneal endothelium, but the difference is not obvious.
