SUBSTANCE: invention relates to medicine, namely to ophthalmology, and can be used for the treatment of a primary open-angle cataract at the background of pseudoexfoliation syndrome in a combination with the cataract. Normalisation of the intra-ocular pressure is carried out by the instillation of b-adrenoblockers and/or carboanhydrase inhibitors. Selective laser trabeculoplasty is performed. Phacoemulsification of the cataract with the implantation of an intraocular lens is performed to the patient the following day after exposure to laser. In the course of performing the phacoemulsification of the cataract washing out pseudoexfoliative particles and pigment granules from the angle of the anterior eye chamber is realised.

EFFECT: method provides an improvement of the outflow of the intraocular fluid, normalisation of the intra-ocular pressure, reduction of the intervention volume and acceleration of the patient rehabilitation due to the elimination of the trabecular net pigmentation, removal of pseudoexfoliative material in a combination with the ablation of cataract masses and increase of the width of the anterior eye chamber angle.
