(1) The top layer of the cornea is not damaged by the procedure, so there is unlikely to be any pain afterwards.

(2) The cornea is kept transparent by the continuous removal of fluid by the endothelial cells.

(3) Your cornea is transparent, allowing light to pass through much like clear glass.

(4) The whole eye is not used, only the cornea , the transparent front of the eye, and the sclera, the white part of the eye.

(5) The spectacles seemed to protect her cornea and retina, which were not damaged.

(6) The cornea , iris, and crystalline lens work together to focus light onto the retina.

(7) Your doctor uses this light to examine the cornea , iris, lens and anterior chamber of your eye.

(8) A cornea transplant replaces the damaged cornea with a disc of healthy tissue from a donor.

(9) The colored circular membrane in the eye just behind the cornea is called the iris.

(10) The limbus is the thin area that connects the cornea and the sclera, the white part of the eye.

(11) To see well, all layers of the cornea must be free of any cloudy or opaque areas.

(12) These rays of light first travel through the transparent cornea , and then through the lens, which helps to focus the light.

(13) However, cystine crystals in the cornea are not usually detectable in the first year.

(14) Oxygen deprivation causes tiny blood vessels to grow into the clear tissue of your cornea .

(15) The iris is the colored part of the eye, which lies behind the transparent cornea .

(16) In the pipeline are many other applications, including vascular, pancreatic, and corneal repair.

(17) The tissue can be used for research and possibly for new forms of deep endothelial corneal transplant.

(18) Tissues such as corneas , skin, bone, bone marrow, cartilage, tendons, veins, and fascia also can be transplanted successfully.

(19) Corneal transplants are performed for people who have damaged or opaque corneas (the outer layer of the eye).

(20) Without moisture, our corneas , which serve as protective domes for the front of the eyes, would dry out and could become cloudy or injured.
