Keratoconus – Impact on Mental Health and Quality of Life Before and After Specific Therapeutic Interventions: A Review

Abstract— Keratoconus is a chronic disease that causes progressive corneal ectasia, leading to significant visual impairment. The asymmetry of vision caused by corneal thinning negatively affects patients’ quality of life and mental health. This review aims to present an impact of keratoconus on mental health and quality of life before and after specific therapeutic interventions.A literature review was conducted using PubMed, focusing on studies published between 2007 and 2025. Keywords related to quality of life and mental health among patients with keratoconus and treatment methods for keratoconus were used, and the most relevant articles were selected. Keratoconus, as a chronic disease that progressively impairs visual abilities, has a negative impact on patients’ quality of life and mental health. The aspects of life most affected by keratoconus include visual and pain symptoms, professional life, social life, entertainment, healthcare, daily activities, and driving. The most common mental disorders developing as a result of the diagnosis and progression of keratoconus are depression and anxiety disorders. Therapeutic methods used in the treatment of keratoconus may contribute to improving patients’ quality of life and mental health.
