Non-significant differences in the post-hoc analysis when comparing the different scenarios.
The absence of markers indicates that those regions were significantly different under all conditions tested.</p
Average and SD of the SE contact lens profiles, after subtracting the naked eye conditions (n = 13).
Images from top to bottom and left to right represent the different meridians measured. Y-axis: dioptres scale; X-axis: degrees scale. The points notated with a blue ‘*’ are the points where non-significant statistical differences were found, after applying Mann-Whitney-U-test and the Benjamini-Hochberg FDR correction.</p
This figure shows the different maps combined with their scale in Dioptres.
1A) Environmental maps. 1B) Contact lens profiles. 1C) Different types of peripheral refractive errors (as power distributions). 1D) Blank map with the segmentation assessment (for display purposes).</p

Computed, theoretical symmetric power profile of contact lenses, based on the values found in the measurements and the theoretical design of the contact lenses.

Error-bar plots of the peripheral refraction and “over-refraction” with the different contact lenses for one subject in each one of the five meridians in-use.
In blue, peripheral refraction or naked eye; in red, over-refraction with near-centre design contact lens; in yellow, over-refraction with distance-centre refraction.</p
Widefield Scanning Wavefront Sensor (WSWS)
This video shows the multi-directional peripheral scanning capability of our novel Widefield Scanning Wavefront Sensor (WSWS). The device can scan along any retinal meridian by using a unique mechanism that involves the concurrent operation of a motorized rotary stage and a goniometer. We tested scanning along four meridians, which involves 60° horizontal scan (±30° from the fovea), 36° vertical scan and two 36° diagonal scans (±18° from the fovea), each completed within a time frame of 5 seconds
