PHACOEMULSIFICATION OF UVEAL CATARACT WITH FEMTOSECOND ASSISTANCE.

To reduce the time and power of ultrasound influence during femtosecond laser-assisted cataract surgery.

The S.Fyodorov Eye Microsurgery Federal State Institution, the Krasnodar Branch, Russia.

5 patients aged 34 -59 years were operated on. Men – 3, women – 2. 2. In all patients - uveal cataract, plane posterior synechiae, anteroposterior axis 15.39 mm - 23.83 mm, anterior chamber depth 2.46 ± 0.46 mm, lens thickness - 4.05 ± 0.15 mm. Operation technique: after performing a valve incision, we divide the posterior synechiae and perform pupil stretching, install the “Malyugin ring” retractor. The next stage is femtoassistance, during which capsulorhexis with a diameter of 5.1 mm is performed, that is the prevention of the of posterior synechiae formation in the postoperative period and the dissection of the cataract nucleus into segments convenient for aspiration. After polishing the capsular bag, we implant the IOL without removing the retractor ring into the capsular bag.

Postoperatively visual acuity of 0.3 - 0.6 was determined in 4 patients (80%), in 1 (20%) below 0.3 is explained by concomitant pathology. In 6 months the posterior corneal epithelium cell loss comprised less than 4%. No intraoperative and postoperative complications were noted.

Femtosecond assistance of ultrasound phacoemulsification with IOL of uveal cataract let significantly lower the power and time of ultrasound exposure, which reduces the possibility of development of ultrasound multiple scattering and acoustic shock, and use the positive effect of the IR laser with a wavelength of 720-1200 nm to provide a therapeutic anti-inflammatory effect and normalize the functions of the eyeball structures.
