A Clinical Comparison of 2 Multifocal Toric XR (Extended Range) Contact Lenses

Astigmatism Clinical Trial

Official title:
A Clinical Comparison of the Comfilcon A (Extended Range) XR Toric Multifocal and Omafilcon B Toric XR Multifocal Contact Lenses

Clinical Trial Summary

This study aims to compare the clinical performance and subjective acceptance of the comfilcon A and the omafilcon B soft contact lenses.

Clinical Trial Description

This will be a randomized, subject-masked, crossover, bilateral study, controlled by cross comparison. Thirty subjects will use each lens type for two weeks in random sequence. Follow-up visits for each lens will be performed after two weeks of wear. Lenses will be worn on a daily wear basis.

The final optical design of comfilcon A contact lens was optimized to improve the quality and two further studies (CV-18-10 and CV-18-11) were conducted after completion of this study to evaluate the modified optical design. ;
