Summary

This study seeks to quantify digital visual performance and subjective visual acceptance of toric contact lenses as compared to spherical lenses in low to moderate astigmatic patients.

Detailed description

This study seeks to quantify the near visual performance and subjective visual acceptance of toric contact lenses as compared to spherical lenses in an astigmatic cohort of patients. Primary Hypotheses: Subjects will have better near visual acuity and near visual performance with toric, as opposed to spherical, contact lens correction. As such, the following hypotheses will be tested: H01: There is no statistically significant difference in near visual acuity or near vision performance between contact lenses corrections Ha1: There is a statistically significant difference in visual acuity or vision performance between contact lenses corrections

Conditions
