Abstract
The invention discloses an optical coupling gel that has a set of desired features for application in eye imaging, including being approved for eye contact, optically transparent, able to maintain normal hydration of the ocular surface, flexible and capable of maintaining a distinct shape, minimal in breakdown/change during use, and easily dispensable/applicable. In one embodiment, the gel is made of Sodium Carboxy Methylcellulose (SCMC), where the amount of the cellulose determines the viscosity of the gel for its particular application. The right amount of gel is contained in an applicator for application to one or two eyes.
