    The article examines the possibility of using toric soft contact lenses (CL) in the treatment of corneal diseases accompanied by pronounced changes in its topography, in which the use of standard soft CL is ineffective. We observed 27 patients with a perforated corneal ulcer, after pterygium removal, penetrating keratoplasty, with a corneal ulcer on the background of an overdose of locally anesthetic drugs, with recurrent corneal erosion after a chemical corneal burn with concomitant simblefaron. After an unsuccessful attempt to use standard silicone-hydrogel SCL, a toric CL was established to all patients of the analyzed group. Toric CL is made of silicone-hydrogel material Lotrafilkon A, which provides the highest level of oxygen permeability and low hydrophilicity.

    Studies have shown that toric contact lenses focused on the irregular surface of the cornea, in contrast to conventional SCL, provide a more durable contact of the lens and its position on the cornea and can be recommended for patients with various pathological conditions of the eye surface: inflammatory-destructive, scarring, in the postoperative period of pterygium surgery, corneal transplantation, etc.

    Key words: toric soft contact lenses, silicone-hydrogel material, eye diseases with irregular corneal surface.
