A Comparison Study Of Three Rigid Gas Permeable Lens Designs In The Fit Of Low Plus Lenses.

This article describes a comparison study of movement and centration of +3.00D rigid gas permeable lenses. Three lens designs were used; regular carrier lenticulars, minus carrier lenticulars and single cut lenses. Choice of lens design is an important aspect in fitting gas permeable lenses. This article attempts to show how lens design of plus lenses makes a difference and what those differences are. Statistically the lenticular designs show better centration and less movement than the single cut design.
