Abstract:
1. An automated system for correcting low order and high order aberrations of refractive errors, said system comprising: a chamber having a fluid therein and an opening; a flexible membrane attached to said chamber and covering said opening; and a sensor configured to automatically control the fluid pressure inside said chamber to thereby alter the curvature of said membrane, such that when the curvature of said membrane is changed so as to have a positive surface, due to an increase in fluid pressure inside said chamber, a combination of said membrane and said fluid acts as a positive lens, and when the curvature of said membrane is changed so as to have a negative surface, due to a decrease in fluid pressure inside said chamber, a combination of said membrane and said fluid acts as a negative lens, wherein said membrane is a transparent elastomeric material, and wherein said system is sized and configured to be positioned externally of the eye.
