Abstract Details

Purpose:

To compare outcomes of femto-phaco and conventional phaco

Setting:

Dnipropetrovsk’s regional eye hospital

Methods:

101 eyes of 83 patients with senile cataract were included . 101 eyes ( group 1) underwent femto-phaco( capsulotomy, lens fragmentation, limbal relaxing incisions ( LRIs), if astigmatism was more than 0.75 D ) by two laser surgens using the Victus (TPV) and subsequent phacoemulsification or aspiration only( C-MICS) by 3 surgens with pulsed ultrasound energy ( Stellaris Visual Enhancement system, Bausch+Lomb). Second group included 100 eyes of 100 patients in whom conventional C-MICS was perfomed , using pulsed ultrasound energy with the same machine (Stellaris ). Patients in both groups were matched for age and nuclear density ( LOCS III) . Preoperatively and postoperatively ( 1 day , 1 week, 1 and 3 months after surgery) uncorrected distance visual acuity (UDVA), corrected distance visual acuity ( CDVA), endothelial cell density ( specular microscopy EM-3000), macular thickness (OCT) were evaluated. Intraoperatively effective phacoemulsification time (EPT) , BSS volume were measured.

Results:

Refractive outcomes and visual acuity are comparable in both groups. Mean EPT and BSS volume were significantly lower in group 1. Mean endothelium cell loss was significantly lower in group 1 ( 6,5% versus 13,2% 3 months after surgery) . Macular thickness was slightly less in the 1 group but the difference was not significant. There was significant reduction of astigmatism in patients with laser LRIs In 5 patients anterior capsule tear occurred and in 2 cases it lead to posterior capsule rupture without vitreous prolapse. In 15 patients miosis developed . In 25 patients different dergrees of subconjunctival hemorrhages occurred. Most of these complications occurred during the first 40 cases

Conclusions:

Femtosecond laser assisted cataract surgery is a safe and very predictable technology. Less use of ultrasound energy and BSS protects the cornea. Another advantage is possibility of simultaneous treatment of astigmatism. There is of course learning curve.
