Abstract Details


To evaluate long-term corneal tissue trauma after femtosecond laser-assisted cataract surgery (FLACS) and phacoemulsification (femtophaco surgery) compared to FLACS and nanolaser emulsification (all laser surgery).


Ophthalmology Clinic of the University "G. d'Annunzio" of Chieti-Pescara, Italy


Forty-two eyes of 42 consecutive cataract patients. The inclusion criteria were age between 65-75 years, andnuclear cataract of grade 3 [nuclear opalescence (NO) 3] (Lens Opacities Classification System III). The exclusion criteria were systemic or ocular pathologiesand previous anterior or posterior segment surgery. Patients were assigned to one of the two groups based on a chronological criterion: Group 1 (all-laser surgery group) and Group 2 (femtophaco group). The femtosecond portion of the procedure was performed with a LensAR platform. Torsional phacoemulsification was performed with a Constellation System (Alcon). Nanolaser photofragmentation was performed with a Cetus Nano-Laser System (A.R.C. Laser).


Three from Group 1 and four patients from Group 2 were lost to follow-up. The two groups did not show statistically significant differences for visual acuity, and corneal thickness (both central and near the tunnel). Previously reported differences in endothelial cell count between groups and between pre-operative measurements for Group 2 seen at 90 days post-operatively still persist after two years (p=0.004 and p<0.001, respectively).


In conclusion, these long-term results showed that the initial lower corneal tissue trauma and lower endothelial cell lose in the all laser cataract surgery group compared to the femtophaco group yielded a long-term sparing of corneal endothelial cells in all laser cataract surgery.
