Abstract Details


To evaluate the effectiveness and safety of laser cataract extraction (LCE)  ('Racot VI' model of Nd: YAG laser λ=1,44 mcm, St.Petersberg, Russia) with femtosecond laser assisted (FLAS) lens fragmentation and anterior capsulotomy (Victus femtosecond laser platform, Bausch & Lomb).


The St. Petersburg Branch of the S. Fyodorov Eye Microsurgery Federal State Institution, St. Petersburg, Russia.


Femtosecond-laser assisted Nd:YAG laser cataract extraction were performed in 45 patients (43 eyes ) since April 2014. 27 women and 16 men were enrolled with a mean age of 70 years±5(SD). The Lens Opacities Classification System (LOCS) III was used for cataract grading. In two cases cataracts were complicated with Fuchs dystrophy and in the other two cases patients had glaucoma. Endothelial cell microscopy was performed before and 1 day after surgery in addition to routine examinations. Real time OCT was used for femtosecond-laser procedure planning and visual monitoring.


No complications occurred neither during femtosecond-laser procedure not during Nd:YAG part. Anterior capsulotomy was an exact circle of 4.5-5.5 mm size in a precise position in all cases. Combination of radial and circular patterns were used. Femtosecond-laser energy was depended on nuclear density and varied from 7800 to 8500nJ. “Crater” and “bowel” technique were used during Nd:Yag laser part of the surgery with 130-220 mJ for nuclear crush. The average density of endothelial cells before surgery was 2448±233cells/mm² (SD). One day after surgery 2444±237cells/mm² (SD). 38 patients had CDVA 0.8 or better one day after surgery, others 0.5 or better.


Femtosecond-laser assisted Nd:YAG laser cataract extraction is safe and effective cataract surgery with minimal Nd:YAG energy required and minimal endothelial cells loss. FINANCIAL DISCLOUSRE: NONE
