Abstract
In this study we show a novel double-pass configuration to correct the spherical refractive error by means of an electro-optical liquid lens. The proposed method enables spherical correction in the -12 D to +7 D range without movable parts using an electro-optical liquid lens. We have measured the optical performance of the spherical corrector in terms of power, pupil size and optical quality verifying that it fits the requirements to be applied to a double-pass system. We have also evaluated the performance of the proposed method in patients by comparison with a conventional double-pass system using a Badal optometer.

Highlights
The double-pass technique, based on recording images of a point-source object after reflection on the retina and a double pass through the ocular media [1] is a powerful tool to evaluate the optical quality of the eye
We have measured the optical performance of the spherical corrector in terms of power, pupil size and optical quality verifying that it fits the requirements to be applied to a double-pass system
It has been widely used in studies assessing the performance of the eye in different conditions, such as age-related changes in optical quality [2] and in clinical studies comparing the performance of phakic IOLs with LASIK surgery [3]
