RISK OF CORNEAL EDEMA
CORNEAL TRANSPARENCY IS KEY TO VISUAL ACUITY

Good vision starts with the correct amount of light traveling into the retina through
the cornea. For a sufficient amount of light to pass through the cornea to the

retina, the cornea must remain clear and transparent. One of the most
important factors impacting transparency levels is the level of hydration. When there’s
excess hydration, transparency may be lost, leading to impaired vision.

CORNEAL DAMAGE COULD RESULT IN EDEMA

In some cases, such as cataract surgery, trauma, infection, or a genetic defect (Fuchs Dystrophy), damage occurs to the andothelial cells that pump fluids out from the cornea keeping hydration levels normal and vision clear.

The endothelial cells are irreplaceable: they are rarely divided, and do not regenerate once damaged. To mend the gap left by the damaged cells, the surviving cells change in size and shape to fill the spaces, hindering the ability to remove excess fluids from the eye.

This results in abnormal accumulation of fluids in the cornea: edema. Edema may result in loss of transparency, and this may lead to eye redness, pain, possibly irreversible scarring of the cornea, and even blindness.

TRANSIENT AND CHRONIC CORNEAL EDEMA NEED TREATMENT

PATIENT HAVE TRANSIENT CORNEAL EDEMA ANNUALLY

Corneal edema can be transient and resolve itself after few weeks or months, without treatment. But chronic edema may be resolved only after corneal transplantation. Corneal edema is a widespread phenomenon following cataract surgery: 450,000 post-operative cataract patients will suffer from transient corneal edema.

Transient and chronic corneal edema patients may benefit from EyeYon’s Hyper-CL treatment for improving visual acuity and pain relief. This may be a bridge to a cure in the case of transient patients or to cornea transplantation in the case of chronic patients. Other current palliative treatments for both patient groups are extremely limited. The only currently available cure for corneal edema is to have a corneal transplant.

HOW IS CORNEAL EDEMA TREATED ?

Out of the possible treatment options available for corneal edema, the treatment chosen will depend on the cause and the severity of the condition. While in mild edema cases no treatment is prescribed, in cases where edema is unresolved for more than a week, ointments and hypertonic solutions are used.

These have a single goal: improve visual acuity while the edema gradually resolves itself. Hypertonic saline has limitations because it’s washed out from the eye quickly and so may not have its desired effect.

Various contact lenses and bandages are used to protect the cornea. But most of these aren’t primarily indicated for treating corneal edema, and therefore they have limited results. Bandage contact lenses may be more useful for the temporary relief of corneal pain since they act to shield the cornea and epithelium from the eyelid. But the hypertonic saline contact time remains too short to be effective.
