title: Quantification of metamorphopsia using hyperacuity techniques.
abstract: We have developed a new technique for quantification of metamorphopsia using a simplified and modified Amsler grid. Furthermore, the technique used is a bisection task, a form of hyperacuity determination. This allows for very fine assessments of metamorphopsia even in the presence of cataracts.
