Contact lens treatment for visual rehabilitation in advanced keratoconus and after “MyoRing” implantation

Purpose

The case report describes the fitting of a scleral contact lens for visual rehabilitation in advanced keratoconus and condition after “MyoRing” implantation.

Material and Methods

Optimizations of the contact lens design were made by evaluation and analysis of cross-sectional images using optical coherence tomography (OCT)..

Results

In the present case, a significant improvement of visual acuity, a reduction of monocular diplopia, and an increase of scotopic visual performance could be achieved.

Conclusion

Scleral contact lenses can be a good alternative to other contact lens treatments to achieve visual rehabilitation in complex corneal situations. Analysis of vertex depths and fitting zones in scleral contact lenses using anterior segment OCT is of great value in determining lens parameters.
