Study on Using Scleral Lenses to Improve Vision and Comfort in Adults with Irregular Corneal Astigmatism from Ocular Surface Diseases

What this Trial Is About

Researchers are studying the use of scleral lenses for patients with irregular corneal astigmatism caused by various ocular surface diseases. This prospective clinical study focuses on how scleral lenses may improve vision clarity, comfort, and patient satisfaction. Patients with corneal irregularities from conditions like post-keratoconus surgery, post-keratoplasty, or trauma are enrolled to assess these lenses effects. Participants are divided into two groups one group will wear scleral lenses while the other group will not receive this treatment. The study includes comprehensive eye exams, such as corneal topography, visual acuity testing, and tear film analysis. Those fitted with scleral lenses are followed up at one week, one month, and three months after fitting to evaluate lens success and comfort. Throughout the study, participants undergo vision tests and complete comfort questionnaires. The main measurement is scleral lens fitting success assessed four hours after application, along with subjective comfort evaluations. Researchers compare vision and comfort before and after lens use. The study spans from initial assessment through three months of follow-up to monitor outcomes and satisfaction.
