Objective. To evaluate the effectiveness of xenotransplantation in surgical treatment of pterygium using coherent optics. Material and methods The study included 37 patients with pterygium of stage I11 and U. All patients were operated on using a xenograft. All patients underwent corneal optic coherence tomography before and after surgery. Results. Coherent optics tomography showed that in all cases of patients with stage I11 pterygium development, the corneal thickness at the periphery of the cornea averaged from 645 мкm to 725 мкm before surgery. In patients with stage IU and U pterygium development, the corneal thickness in the periphery ranged 730 мкm. In the center of the cornea, the thickness averaged 768 мкm. In the postoperative period, in all cases, the thickness in the periphery was 534 мкm, and in the center 564 мкm. Conclusions. Optics coherent tomography allows to objectively assess the condition of the cornea before and after surgery.
