Scleral contact lenses in normal corneas: is it possible to improve visual performance?

DOI: 10.37039/1982.8551.20260025

ABSTRACT

Objective:

To analyze visual performance in digitally active volunteers using ScCLs.

Methods:

ScCLs were fit in seven participants and evaluated during four visits over 45 consecutive days. Reading speed tests were performed with MNREAD-P charts and texts developed by the Department of Speech Therapy of the authors’ institution. Post-study, participants were interviewed and completed the 8-item Contact Lens Dry Eye Questionnaire (CLDEQ-8).

Results:

During ScCL wear, 85.7% showed increased reading speed on MNREAD-P charts, with similar results on the texts of the authors’ institution. Interviews highlighted initial ScCL handling difficulty, improved comfort, and preference over soft lenses for physical activities.

Conclusion:

This study underscores the need to explore new contexts impacting digital tasks requiring optimal visual performance, suggesting ScCLs as beneficial. Further research is necessary to elucidate these aspects.
