MFN lens profile compared with choroidal thickness changes.

Abstract

(A) Concentric structure of the MFD lens consisting of a 1.7 mm center with distance prescription and a progressive addition zone up to 8.5 mm. (B) Horizontal power profile of the MFN lens as measured and adapted from Wagner et al. [25]. (C) Changes in choroidal thickness from temporal to nasal retina after wearing the MFN lens for 30 min in the present study. The bars represent the temporal perifoveal, temporal parafoveal, central, subfoveal, central, nasal parafoveal and nasal perifoval retinal ETDRS area from left to right.</p
