Applying individual rigid scleral contact lenses in visual rehabilitation of patients with an irregular corneal surface. Clinical cases

Scleral rigid contact lenses efficiently correct the vision of patients with irregular corneas. Purpose. To study the features of contact correction and visual rehabilitation of patients with irregular corneal surface using individual scleral rigid contact lenses. Results. Three clinical cases of successfully selected rigid individual scleral lenses for patients with an irregular corneal surface that appeared after a penetrating keratoplasty, implantation of intrastromal corneal segments, and eye injury. The expected refractive result was achieved; high tolerance and good adaptation to lenses was revealed. Conclusion. Scleral RCL can be successfully used in patients with irregular cornea to improve visual acuity, reduce the number of aberrations, restore binocular vision and social adaptation.
