Future emphasis will be placed on surpassing habitual GP performance and reaching a normal age\u2010matched criterion for both VA and aberration measures. Achieving these goals may require a more thorough understanding of the relationship between visual performance and residual aberration experienced during custom lens wear through the use of image quality metrics predictive of visual performance.<\/jats:p>\n
