Table 4.

HC and LC visual acuity data recorded with the GP lens and each successive custom lens are reported. In all cases, high contrast logMAR VA with the final custom lens is equal or superior to levels obtained with the habitual GP, but still does not achieve normal levels. Average and standard deviation are reported.
