Unfortunately, not everyone is the ideal candidate for contact lenses. There are certain conditions that present difficulties– though these can be addressed. These include any form of astigmatism, presbyopia, dry eyes, giant papillary conjunctivitis, post-refractive surgery, and keratoconus. These things don’t mean that you can’t wear contacts, just that additional steps should be taken for successful wear. Let’s go into a deeper analysis of each condition and potential contact lens fixes.
Astigmatism is defined as a condition that causes blurred vision due to the cornea being irregularly shaped or sometimes because of the curve of the lens inside the eye. There are more than 3 million US cases per year. Astigmatism doesn’t prevent from being able to wear contacts, you just need a different type of lens.
Lenses that are uniquely manufactured to fix astigmatism are known as “toric” lenses. Almost all are soft lenses. These lenses contain varying prescriptions in different areas and elements designed to prevent rotation or movement of the lens on your eye. These prescriptions have to be correctly positioned in front of specific areas.
There are anti-rotation models of these lenses if they move around on the eye to the point of blurred vision. If soft lens movement persists in causing issues, gas permeable lenses fix astigmatism as well.
Wearing contact lens can be extremely strenuous if you have dry eyes. You’ll likely experience a gritty dehydrated feeling, the constant discomfort of something being in your eye, the feeling of burning, redness of the eyes, and blurry vision.
Prior to doing anything else, you have to treat the condition. There are multiple methods of this being done like artificial tears, prescribed eye drops, supplements for nutrition, and procedure performed by doctors named punctual occlusion.
Only after treatment and containment of symptoms can contact lens wear be attempted. Some soft lens perform more efficiently over others. Gp lenses can also be more effective in certain cases over soft lenses for those with dry eyes since these don’t have the risk of being drying.
You should be sure to replace contacts frequently and limit how long you wear them daily so as to lessen symptoms
Giant Papillary Conjunctivitis
GPC is an allergic reaction of the eye that occurs when one or several small round bumps (papillae) develop on the underside of the eyelid. This could be caused by deposits of protein on soft contacts.
In most cases, switching to daily disposable soft lens should fix this issue since their wear is too short to allow protein deposits to collect on them. GP lenses are normally a smart fix too since protein don’t easily grip to them. Cleaning GP lenses once a day also gets rid of lens deposits for the most part.
Some people with GPC may need prescribed eye drops to decrease inflammation before contact wear.
This condition of losing focusing ability is expected as you get into your 40s.
Fortunately, nowadays numerous types of multifocal contact lenses have been manufactured specifically to treat presbyopia. Monovision is an alternative for presbyopia . The practice of your contact lenses having different prescriptions for each eye– like one being optimized for nearsightedness, and the other for farsightedness.
While getting your contacts fitted, a professional will assist in choosing the right kind for you.
