Several problems can take place because of lens wear too, so care should be delivered to avoid these problems. Many doctors refer their patients to ophthalmolgists for evaluation and management of their lens related problems.
How can lenses damage a persons vision?
Contacts may cause many problems in the eye, but only a few commonly encountered diagnoses might cause severe problems. Giant papillary conjunctivitis, punctate keratopathy and ulceration are the three most problematic issues.
Giant Papillary Conjunctivitis (GPC)
GPC occurs on account of overwear of lenses, either lots of hours each day, or way too many days consecutively. Symptoms include itching, inability to wear lenses all day, and mucous discharge.
Punctate Keratopathy
Overwear could also result in a problem at first glance from the cornea, where the top layer of cells are damaged. The eye doctor sees tiny pinpoint scratches about the cornea a result of decreased oxygen to the people cells.
The most risk of a threat to vision will be the corneal ulcer. In this case, bacteria penetrates the surface from the cornea, causing an infection that seems as a white spot. If untreated, this infection can penetrate and cause infection inside the eye.
How could we prevent contact problems?
The most critical thing for patients to accomplish is control their contact wear. Although many lenses are made and approved for overnight wear for between 2 and a month, most eye doctors recommend nightly removal and cleaning. The single most common cause of lens related problems is overwear, and a large study established that overnight wear is fourteen times more likely to cause ulcers than another risk factor.
Are there safer alternatives to wearing disposable lenses?
Of course, glasses will be the safest method to correct vision without running the potential risk of contacts. Since glasses tend not to touch your eyes, they can’t make trouble. On the other hand, because they are away from the eye area, the don’t give vision that is as sharp as disposable lenses. Rigid or hard lenses are better yet because they float on the surface in the eye, effectively smoothing out any rough spots, giving the best vision.
Recent studies also show that LASIK has less risks than contacts, this specific a surgery. It is a lot more common for contact lenses to cause infection, inflammation etc vs. LASIK.
