 The objective of the research was to evaluate the results of executing dosed femtosecond laser assisted posterior capsulorhexis in the surgical treatment of congenital cataract in combination with the syndrome of primary persistent hyperplastic vitreous.

Material and methods. From 2014 to 2017, surgical treatment with femtosecond laser assisted posterior capsulorhexis was carried out in 10 children (10 eyes) with congenital cataracts in combination with syndrome of primary persistent hyperplastic vitreous (PPHV) at Kaluga branch of the S. Fyodorov Eye Microsurgery Federal State Institution. Six children were diagnosed with PPHV syndrome of the 1^st degree, and 4 children ― with the 2^nd degree of severity (according to Sudovskaya classification). The age of children at the time of surgery was from 3 to 12 months. The observation period varied from 8 to 36 months.

The posterior capsulorhexis was performed using a FemtoLDV Z8 femtolaser (Ziemer, Switzerland).

Results. In all cases, an ideally round and flat posterior capsulorhexis of the required diameter was obtained, clearly localized according to the set parameters. There were no intersections; mobilization of the carved fragment of the posterior capsule for further manipulation took place without difficulties. There were no intra- and postoperative complications. Visual acuity in patients at the end of the follow-up period was from 0.1 to 0.3 without correction, and from 0.2 to 0.6 with correction.

The conclusion. Femtolaser technique of performing a posterior capsulorhexis in the surgery of congenital cataract in children in combination with PPHV syndrome allows reducing the number of intraocular manipulations, the risk of complications, the operation and anesthesia time in children compared to the technique of manual posterior capsulorhexis using the 25G vitreal instruments.

Key words: femtolaser, posterior capsulorhexis, congenital cataract, syndrome of primary persistent hyperplastic vitreous body.
