The effectiveness of corneal collagen cross-linking with photorefractive keratectomy in initial primary keratoectasia
Early diagnosis and treatment of keratoconus (KC) and the second most common form of keratoectasia – pellucid marginal degeneration (PMD), are an important problem in ophthalmology, since the disease is more often manifested in adolescence, predominates in young able–bodied individuals and often leads to blindness and visual disability [1, 6, 8]. Currently, a new method of treating these pathologies is the method of cross-linking of corneal collagen (CCL) [1, 12, 13]. The least traumatic, safe, highly predictable of them is photorefractive keratectomy (PRK) in combination with CCL [3-5, 11]. The aim of the work is to study the clinical efficacy and safety of photorefractive keratectomy and cross-linking of corneal collagen in the correction of ametropia in initial primary keratectasias.
