Prevalence of Keratoconus and The Role of Advanced Optical Techniques for Correcting Vision

Abstract

A cross-sectional study, patients at the Benghazi Teaching Hospital for Ophthalmology and Delta Optics Center, aimed to assess the prevalence of keratoconus (KC) and investigate the distribution and efficacy of advanced optical techniques used to treat it. A survey with 500 participants was conducted, and SPSS was used to analyze 413 valid responses. The findings showed that keratoconus was quite prevalent (59.6%), specifically among younger age groups. While there was no significant correlation between KC and age, gender, or corneal thickness, there was a significant statistical correlation between KC and irregular astigmatism and the type of treatment. Although keratoconus patients were more likely to undergo more complex procedures like corneal cross- linking, intracorneal ring implantation, and transplantation, glasses remained the most common corrective measure. These findings highlight the importance of early screening, patient education, and the application of state-of-the-art diagnostic and therapeutic approaches in ophthalmic care.
