Several problems can occur because of contacts wear too, so care should be delivered to avoid these complaints. Many doctors refer their patients to ophthalmolgists for evaluation and management of their lens related problems.
How can contact lenses damage a person’s eye?
Contacts may cause many problems in a person’s eye, but only several 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 because of overwear of lenses, either too many hours daily, or lots of days uninterruptedly. Symptoms include itching, inability to wear lenses all day long, and mucous discharge.
Punctate Keratopathy
Overwear could also lead to a problem on the surface with the cornea, the place that the top layer of cells are damaged. The eye doctor sees tiny pinpoint scratches about the cornea brought on by decreased oxygen to the people cells.
The most potential for a threat to vision will be the corneal ulcer. In this case, bacteria penetrates the surface from the cornea, causing disease that appears as a white spot. If untreated, this infection can penetrate and cause infection inside a persons vision.
How will we prevent contact problems?
The most important thing for patients to perform is control their contact lens wear. Although many lenses are made and approved for overnight wear for between 2 and four weeks, most eye doctors recommend nightly removal and cleaning. The single most popular source of contact lens related problems is overwear, plus a large study indicated that overnight wear is fourteen times more likely to cause ulcers than any other risk factor.
Are there safer options to wearing lenses?
Of course, glasses would be the safest approach to correct vision without running potential risk of contact lenses. Since glasses do not touch your eye area, they can not make trouble. On the other hand, since they are away from your eyes, the tend not to give vision which is as sharp as lenses. Rigid or hard disposable lenses are even better because they float on the outside from the eye, effectively smoothing out any rough spots, giving the top vision.
Recent studies also show that LASIK has less risks than contact lenses, while it’s a surgery. It is considerably more common for lenses to cause infection, inflammation etc vs. LASIK.
