Patients and Methods
This study was a prospective, interventional, consecutive case-control study of 201 eyes that underwent cataract surgery by a single surgeon at a single regional center. Controls (n = 51) underwent conventional phacoemulsification followed by insertion of IOL. Cases (n = 150) included patients who elected to undergo femtosecond laser pretreatment using the Catalys Femtosecond Laser System (OptiMedica, Sunnyvale, CA) followed by phacoemulsification and insertion of an IOL. The study conformed to
Results
Patient demographics and baseline characteristics were similar between cases and controls (Table 1). All patients were included in the study and underwent complete assessment. The mean age was 72.8±10.5 years in the femtosecond group versus 71.8±10.8 years in the control group. Mean cataract grade was 2.59±0.71 in the cases compared with 2.52±0.72 in the controls. Cataract grades between subgroups analyzed were not significantly different. There were 28 women (54.9%) in the control group
Discussion
This study found that femtosecond laser pretreatment significantly reduces phacoemulsification time. The reduction in effective phacoemulsification time in this study was consistent with that of previous studies.3, 4, 5 Currently, only 1 published study has reported the reduction in phacoemulsification time and energy within in vivo human eyes.4 The present study found a statistically significant reduction in mean EPT of 84% when cataracts were pretreated with the femtosecond laser.

2022, Advances in Ophthalmology and OptometryCitation Excerpt :The reduction in EPT with femtosecond nuclear fragmentation was noted to be greatest in lenses with denser crystalline lens opacification [28]. Palanker and colleagues demonstrated that 30% of femtosecond cases can reach 0 EPT, whereas 0% of conventional cases reached 0 EPT [29]. A reduction in EPT may be particularly helpful in hypermature or dense cataracts.
