| dc.description | This case study presents the fitting of a rigid contact lens in a 21-year-old male patient with keratoconus. The patient arrives at the optometric consultation after being referred by the corneologist for the adaptation of the contact lens (LC). He refers to having started treatment with an ophthalmic antihistamine and artificial tears a month ago due to allergic conjunctivitis and dry eye. After evaluating the corneal tomography, it was decided to adapt a contact lens in the left eye since it did not improve with optical correction, it presented a stage III according to Belin's ABCD classification and also because of the patient's economic situation. The right eye presents stage I keratoconus. Visual acuity was taken, refraction with retinoscopy, autorefractometer, and finally biomicroscopy. It was decided to adapt a rigid gas permeable contact lens (LC RPG) in the left eye and additionally a frame lens to compensate for the ametropia of the right eye. During adaptation, fluorograms are performed to observe the behavior of the lens and determine the base curve of the lens. In two more sessions, the adaptation of the lens is evaluated, in addition to a control for allergic conjunctivitis and dry eye. The LC RPG improved the visual quality of the patient and provided visual comfort during the 8 hours of its use. The final recommendations were to maintain adequate lens cleaning and perform a corneal tomography in 6 months to assess the progression of keratoconus. | es_ES |

| dc.description.abstract | En este estudio de caso se presenta la adaptación de un lente de contacto rígido en un paciente masculino de 21 años con queratocono. El paciente llega a consulta optométrica tras ser derivado por la corneóloga para la adaptación del lente de contacto (LC). Refiere haber iniciado un tratamiento con antihistamínico oftálmico y lágrimas artificiales hace un mes por conjuntivitis alérgica y ojo seco. Tras la evaluación de la tomografía corneal se decide adaptar lente de contacto en el ojo izquierdo ya que no mejora con corrección óptica, presenta un estadio III según la clasificación ABCD de Belin y además por la situación económica del paciente. El ojo derecho presenta un queratocono en estadio I. Se realiza la toma de la agudeza visual, refracción con retinoscopía, autorrefractómetro, y finalmente biomicroscopía. Se decide adaptar en el ojo izquierdo un lente de contacto rígido permeable al gas (LC RPG) y adicional un lente de armazón para compensar la ametropía del ojo derecho. Durante la adaptación se realiza fluorogramas para observar el comportamiento del lente y determinar la curva base del lente. En dos sesiones más se evalúa la adaptación del lente, además de un control para la conjuntivitis alérgica y el ojo seco. El LC RPG mejoró la calidad visual del paciente y proporcionó confort visual durante las 8 horas de su uso. Las recomendaciones finales fueron mantener una limpieza adecuada del lente y realizarse una tomografía corneal en 6 meses para evaluar la progresión del queratocono. | es_ES |
