PURPOSE

This study compares the effect of implantation of intrastromal corneal ring segment (ICRS) and fitting of individual scleral rigid contact lenses (RCLs) on visual functions in patients with stage II—III KC after previously performed corneal collagen cross-linking.

MATERIAL AND METHODS

The Helmholtz National Medical Research Center of Eye Diseases examined and treated 34 patients (69 eyes) aged 18 to 33 years with stage II—III KC. The study included patients who had previously undergone standard corneal collagen cross-linking. Depending on the type of optical correction, the patients were divided into two groups: patients in group 1 underwent ICRS implantation using a femtosecond laser; patients in group 2 were fitted with individual scleral RCLs.

RESULTS

Improvement in clinical and functional parameters was observed in both groups. A higher clinical and functional result was achieved in group 2.

CONCLUSION

For patients with stable stage II—III KC, it is advisable to recommend fitting of individual scleral RCLs for visual rehabilitation.
