Contact lenses besides being used for fashion, are now also used for daily activities. people choose contact lenses for visual aids because of their appearance or fashion and their easy use. Some people don’t understand how to treat contact lenses properly. As a result contact lenses become an effective medium for the development of fungi and germs that cause eye disease.
When used, the contact lens surface is affixed to the front of the eye. The very close distance allows the transfer of germs from the contact lens surface to around the surface of the eye fluid. Indications for germs are usually characterized by inflammation of the eye. At first, the infection does not show very serious symptoms, but over time it can cause permanent eye damage to blindness.
Contact lenses are the main source of transmission of eye infections both caused by bacteria, fungi, parasites and viruses. The infectious agent on the surface of the lens is caused by inappropriate use and treatment, such as leaving contact lenses exposed to water, using inappropriate lens cleaning fluid, and not changing contact lenses regularly.
Type of infection caused by the use of contact lenses
Infection caused by the use of contact lenses can occur in the cornea of the eye or known as keratitis. This disease is generally caused by various germs, thus triggering inflammation and damage. But the damage that occurs to the cornea can be sedentary so it needs a transplant in cases of severe infection.
Based on the type of cause, this infection can be divided into four types, including:
This infection is caused by the bacteria Pseudomonas aeruginosa and Staphylococcus aureus. We can find these two bacteria easily on the surface of the soil and water, even in the human body. Wearing contact lenses that are touched by the surface of the body or objects without being sterilized can easily trigger bacterial keratitis infection. Bacterial keratitis in general quickly irritates the eyes, immediately stop using contact lenses when you experience discomfort when wearing contact lenses to prevent the keratitis from getting worse.
Fungal keratitis is triggered by various Fusarium, Aspergillus and Candida fungi. This fungus that triggers keratitis is also found in the human body. This type of fungus can also be found easily in open environments with humid conditions. The nature of the fungus can easily spread to other parts of the eye, so an anti-fungal drug is needed within a few months to prevent the keratitis from getting worse.
Although parasitic keratitis is rare, parasitic infections of the cornea may occur and this is a serious infection. Parasitic keratitis is caused by the parasitic microorganism Acanthamoeba. Like most parasites, Acanthamoeba is not only destructive but also lives from individuals
who he descended on.
These parasites can be easily found on the soil surface and body of water including tap water and moist air conditioning. The use of this contact lens is the only cause of Acanthamoeba infection in the eye, because this parasite must come in direct contact with the surface of an organ to infect it.
Apart from causing eye discomfort, Acanthamoeba infection also causes whitish discoloration in the cornea of the eye. Early diagnosis and treatment is very necessary because when it gets worse it takes serious medical action and eye surgery.
This type of keratitis is triggered by the Herpes Simplex Virus (HSV). The HSV virus can only be found in humans and can only be transmitted through direct contact with individuals infected with HSV. Unlike other types of keratitis, keratitis triggered by HSV can be transmitted. Viral keratitis also allows recurrent infections, and this may occur in people with HSV infection. Viral infections depend on one’s endurance or immunity, for which the treatment of viral keratitis requires anti-viral drugs and eye drops. Eye surgery is rarely needed to treat viral keratitis.
How to avoid infection from contact lenses in the eye
To prevent eye infections, you must understand the eye conditions and the risks of using contact lenses that are not appropriate. Here are a few things you need to pay attention to in contact lens usage:
- Perform a routine eye examination to determine the presence of infection and the suitability of contact lenses with the eyes.
- Hands must be in a sterile condition when they will use and remove contact lenses.
- Always clean contact lenses with lens cleaning fluid regularly and do it carefully. Do not add new liquid to the old liquid that is still on the lens surface.
- Do the appropriate contact lens storage, avoid putting the lens in the open space for too long, and replace the lens every three months.
- Consult with an ophthalmologist about the duration of use and when contact lenses need to be replaced.
- Remove contact lenses when you sleep because it can cause the transfer of germs and increase the risk of infection.
- Avoid activities that cause contact lenses to be exposed to water such as when bathing or swimming. Use swimming goggles if you need contact lenses when swimming.
- If the lens is exposed to water, you should immediately replace it with a new one to prevent infection.
