Abstract
Pterygium is a common disease of the ocular surface associated with the growth of fibrovascular tissue from the conjunctiva through the limbal zone to the cornea, which in the advanced stage is not only a cosmetic defect, but also reduces visual acuity. The main problem of successful surgical treatment of pterygium is the high risk of recurrence. In modern pterygium surgery, the method of choice is the use of the so-called barrier method of treatment, with the replacement of the defect of the bulbar conjunctiva above the bed of the removed pterygium with various biocompatible tissues. These operations are performed selectively or in combination with adjuvant therapy. The search for an adequate method of treating pterygium, which combines ease of implementation, minimal risk of recurrence and complications, and optimal cosmetic effect, remains an urgent problem in modern ophthalmology.
