Зрительная реабилитация при двустороннем кератоконусе с помощью индивидуальных склеральных линз: клинический случай.

Keratoconus is a progressive, non-inflammatory corneal ectasia characterized by corneal thinning and protrusion, leading to irregular astigmatism and significant visual impairment. Although historically considered a rare condition, its prevalence is notably higher in the Middle East compared to global averages. Recent studies report prevalence rates of up to 4.79% in Saudi Arabia, with similarly elevated figures in neighboring Gulf countries, including Qatar, attributed to genetic predisposition, environmental factors, and high rates of consanguinity [¹,²]. In Qatar, although specific large-scale epidemiological studies remain limited, anecdotal and clinical observations suggest a rising trend, particularly among young adults seeking refractive surgery consultations [³,⁴]. Early detection is vital, as modern diagnostic tools, such as corneal topography and Purkinje image assessment, allow for timely interventions. Management strategies, including scleral contact lenses and corneal cross-linking (CXL), not only improve visual function but also halt disease progression, reducing the need for more invasive procedures such as corneal transplantation [⁵].
