Comportamiento de lente de contacto limbal y APC para el Manejo de un paciente con queratocono en Tuluá, Valle en 2025: reporte de caso

Abstract

Keratoconus is considered a bilateral and asymmetrical ocular disease that causes progressive thinning and steepening of the cornea, leading to irregular astigmatism and reduced visual acuity (1). The thinning of the cornea occurs in the central or paracentral area, most commonly in the inferotemporal zone (2). As the condition progresses, conventional solutions such as the use of spectacles become less effective in restoring patients' visual acuity. Objective: To evaluate the performance of large-diameter limbal gas permeable contact lenses and peripheral asphericity designs in the management of keratoconus. Methodology: Clinical case report Case presentation: This report presents the clinical case of a 22-year-old patient from Tuluá, Valle del Cauca, diagnosed with keratoconus and who underwent penetrating keratoplasty in the right eye three years ago. The patient had multiple ophthalmology evaluations but had not been fitted with any optical correction for the condition. Results: A large-diameter limbal gas permeable contact lens and a lens with peripheral asphericity were fitted in both eyes. Good visual acuity was achieved with both lens designs, but one of them provided limited visual comfort. Conclusions: The use of the contact lens in the right eye was discontinued. Each design used was selected considering the patient's budget. The Quantifiable Peripheral Asphericity (QPA) lens provided adequate visual acuity improvement but was not suitable in terms of comfort
