Reporte De Caso: Adaptación De Lentes Blandos Especializados ARC en Paciente con Queratocono (Post Implante de Anillos Intraestromales)

Abstract

Keratoconus is a progressive corneal disorder characterized by corneal thinning and protrusion, associated with collagen dysfunction, which leads to significant alterations in both the quantity and quality of the patient’s visual performance. Various therapeutic alternatives are available for its management, including corneal cross-linking, intracorneal ring segment implantation, and corneal transplantation in advanced stages, as well as multiple options for visual correction using spectacle lenses and contact lenses. The aim of this study is to describe the fitting of Flex Lens ARC contact lenses in a patient with a history of bilateral intracorneal ring segment implantation and poor tolerance to rigid contact lenses and spectacles. This case report presents a clinical and topographic evaluation followed by the fitting of special-design soft contact lenses (Flex Lens ARC). Current topographic parameters and their influence on the lens fitting were analyzed. As a result, a visual acuity of 20/25 was achieved in both eyes, with good comfort and tolerance. The fitting demonstrated stability, good centration, and satisfactory repeatability in subsequent lens orders. In conclusion, this case highlights the importance of an individualized and dynamic evaluation in keratoconus patients treated with intracorneal ring segments, as well as the clinician’s knowledge of available technologies to achieve a functional and satisfactory visual outcome.
