Keratitis Causes Contact Lens Wearers Problems
Pathogens That Can Cause Keratitis
I am outlining the common specific types of pathogens that can cause a form of keratitis and some will be more serious than others. These usually affect people wearing contact lenses that are in need of some type of immediate attention.
Amoebic keratitis - Amoebic disease of the cornea is the most severe corneal infection, which usually relates to contact lens wearers. It is for the most part caused by Ancanthamoeba. The CDC in 2007 declared a health advisory due to a deepened risk of Acanthamoeba keratitis - (AK) is associated with treatment from Advanced Medical optics (AMO) complete Moisture Plus Multi-Purpose eye solution.
Bacterial keratitis - Bacterial disease of the cornea can come from an injury or from wearing contact lenses. The germs contained are Staphylococcus aureus and for people with contacted lenses, Pseudomonas aeruginosa. Pseudomonas aeruginosa contains enzymes that can abstract the cornea.
Fungal keratitis - cf. Fusarium, induces recent tendency of Keratitis through the likely vector of Bausch & Lomb ReNu with MoistureLoc contact lens solution.
Herpes Zoster Keratitis - Herpes Zoster Keratitis -Viral infection of the cornea is often caused by the herpes simplex virus and can leave a dendritic ulcer.
Initially, reports of AK cases declined following the recall of contact lenses in the year 2007. New information has surfaced, which appears to show that the numbers of Keratitis cases still remain higher than the numbers reported before the outbreak occurred. A Keratitis Investigation Team called (AKIT) was formed to investigate the uncertainty that might be associated with new AK cases. The AKIT team includes organizations such as: partner ophthalmology centers and laboratories; CDC; other federal, state local public health partners and academic institutions around the country. The investigation was started on March 21, 2011.
How Were the Rising Number of Nationwide AK Cases Detected?
As part of the 2007 Keratitis outbreak investigation, the CDC went to institute an inconspicuous surveillance system with associating laboratories and ophthalmology centers nationwide, to pursue trends in the development of Keratitis cases in the United States. After seeing a commencing decline in the number of cases that were being reported. These centers following the recall of a contact lens solution from the year 2007, saw actual case reporting to be leveled off but the number of cases reported from these centers has not returned to the levels discovered before the 2007 outbreak.
Since contact lenses seem to be a big Problem here are some tips on how to reduce your risk?
Keratatis is very common among people that wear contact lenses. Public health officials do not yet know what dangers are associated in this seeming increase, all contact lens users need to use these suggestions to help reduce their risk for Keratatis and other eye infections: Wear and replace contact lenses according to the schedule recommended by your eye care provider. Remove contact lenses before any activity involving contact with water, this includes taking a show, hot tubs, or even swimming. See your eye care specialist for regular eye examinations. Wash hands with warm soap and water and make sure they are dry before handling contact lenses. Clean contact lenses given by the manufacturer's directions and instructions from your eye care provider.
Use a new cleaning or disinfecting solution any time lenses are cleaned and stored. Never reuse or top off old solution.
Never use saline solution or wet drops twice to disinfect lenses. Neither solution is an effective way.
3. Store reusable lenses in the proper storage case.
4. Storage cases should be rinsed with sterile contact lens solution (never use tap water)and lift open to dry after each use.
5. Replace storage cases every few months.
