EYETECH Opaques,

Cosmetic and Prosthetic Lenses

 

Eyetech Opaques have been designed for those patients that require a radical change of iris color.  The Lenses are made opaque across all or part of the back of the lens and then a tint is applied to the front surface.

 

Prosthetic Lenses are used to hide corneal disfigurements such as scars or to treat a wide range of conditions including photophobia, when certain light, colors and intensities can cause problems to the unprotected eye.

(Prosthetic and therapeutic contact lenses can only be order by a licensed eye care practitioner. )

a piece of the iris is removed to address a different ocular affliction, leaving a hole

Lens Subluxation

Partial dislocation of the crystalline lens

Iris Coloboma

embryotic tissue defect where the iris is not fully developed and pupil can appear irregular or “spilled”

Amblyopia
(lazy eye)

an opaque lens is used as an occluder on the good eye, forcing the lazy eye to work

Diplopia
(double vision)

can be due to many things but may be corrected with opaqued contacts with a small pupil hole, in certain forms of esotropia (eyes turning inward)

Heterochromia

Scarred and/or
opaqued cornea

due to trauma or illness

Fixed, dilated pupil
