What is done in a cross-linking operation? Is this operation really effective?

The cornea is made of a network of collagen fibers. In this disease interlinking connections between the collagen fibers become week due to which the corneal thickness decreases and the cornea is weakened.

In this treatment, the collagen fibers are activated and their linkages between each other are potentiated and their cross-links are fastened together with each other. A chemical named riboflavin is activated with a special type of ultraviolet radiation, as a results the fibers of the collagen come closer to each other again, and thickness of cornea increases. This process is called cross-linking. This operation is also called CXR or CR3 operation.

As this chemical and radiation machine are still expensive so the operation is much expensive and is being performed at very few places.

The pictures below show the different stages of this operation

I am preparing the eye fpr operation

I am instilling a precious chemical into the eye so that it can be effected by the radiations

I am performing patchymetry to know is thickness sufficient? otherwise I will use another chemical also

I am exmining the flare in the eye that is it sufficient to be operated

I am iapplying radiations to the eye

What is appearance of cornea when it is damaged? What are symptoms other than its abnormal appearance?

If there is a minor defect, the color of your eye may appear slightly greyish. If cornea has been significantly damaged, then the eye appears white in colour. Vision deterioration is proportional to the whiteness. If inflammation is also present, then, there is pain, redness, photophobia. Bright light is intolerable. But in the case of old healed lesion, usually only vision deterioration and the white appearance is present.

The part of eye which has been cut from the donor's eye is being seen in this picture

In this picture the eye being operated is being seen with white cornea

The diseased cornea has been cut off.

The part of the donor eye has been cut from it, now it will be sutured to the recipient's eye
