World renowned Moorfields Eye Hospital has recently launched a campaign to encourage contact lens wearers to ensure they take care of their eyes. The hospital has seen a marked increase in cases of eye infections relating to contact lens wear. Most worryingly an increase in an infection called acanthamoeba keratitis which can be extremely difficult to treat and in the most serious cases, can see the patient require a corneal transplant.
Tiny parasites called acanthamoeba can live in water so should your lenses come in contact with water the parasites can take up residence in your eye. If they aren’t killed through thorough cleaning, this serious infection can develop. This is a serious yet thankfully uncommon infection, however with cases of it on the increase, now is a good time to remind yourself of some basic guidance which applies to all lenses.
• Always wash and dry your hands thoroughly before handling your lenses.
• After removing your lenses, clean them immediately. Don’t store them without cleaning them first. Cleaning will remove mucus, protein, make up and debris that naturally build up on the surface during the day.
• Never use tap water (or saliva!) to rinse your lenses or case. Microorganisms can build up in water, even distilled water, and can cause infections or even sight damage.
• Ensure your lens case is kept clean. Replace your case every time you open a new bottle of solution.
• Use clean solution every time. Don’t reuse or top up.
• Do not sleep in your lenses unless advised by your optometrist.
• Ideally lenses shouldn’t be worn when swimming but if you do wear them make sure you wear goggles to reduce the chance of contact with pool water.
• Follow the cleaning guidelines you were given, using the recommended products. Doing this will reduce the chance of picking up a nasty eye infection.
• Insert your lenses before applying make up.
• Have an up to date pair of spectacles on hand should you pick up an infection. Many treatments require you to stop wearing your lenses for the duration of the treatment so don’t be caught without a backup.
• Don’t use any eye drops without advice from your optometrist.
Remember these three simple questions:
• Do my eyes feel good with my lenses? You have no discomfort.
Do my eyes look good? You have no redness.
Do I see well? You have no unusual blurring with either eye.
If the answer to any of these questions is no, take out your lenses and consult us straight away.
