Corneal Ulcers

I saw a patient with one of these eyes. Quite avoidable really. He called in the morning after having a red irritated eye for a couple of days. He confessed that he really needs to get better at replacing his contact lens on schedule and cleaning them. He is correct.

What we are looking at here is an isolated bacterial corneal infiltrate of white blood cells that are attacking the over-populated bacteria that have broken into his cornea. This will become a corneal ulcer in no time. Yes, ulcer. Imagine this in front of the center of your pupil...

Stressing out the cornea leads to such things. Contact lenses stress corneas, old soiled contact lenses stress corneas in a dramatic way.

Classic ways to stress your corneas with contact lenses:
1. sleep while wearing them
2. wear ill-fitting lenses
3. improper use of solutions
4. over-wear lenses
5. use old soiled contact lens storage case
6. expose contact lenses to water and wear them
7. handle lenses with soiled hands

The bottom line is that you should always wear a good lens, and you should be disposing of your lens while it is still good. Yes, dispose of a monthly lens before a month if it goes bad. And, no, don't re-use a daily lens if it is still good.

Thanks for taking care of your eyes!
