what is the incidence of corneal neovascularisation in contact lens wearers,its symptoms,how to recognise it e
405888
Corneal neovascularization has a low incidence among contact lens wearers who properly care for their lenses, follow all cleaning directions, and discard their lenses at the appropriate times. Typically patients who use extended-wear lenses (such as the kind you can leave in for two-weeks at a time) experience this problem much more often. However, with the invention of more permeable substances, contact lenses (such as Acuvue Advance or Night & Day) are much more permeable to oxygen and help reduce the risk of corneal neovascularization.\n\nThe symptoms of corneal neovascularization include diplopia (double vision), eye pain, redness, or minor yet noticable problems within the visual field. If you are a contact lens wearer then routine eye examinations by optometrists or ophthamologists should include screening for corneal neovascularization. The healthcare professional should be able to easily appreciate fine, irregular vasculature permeating into the cornea on one or both eyes.\n\nCorneal neovascularization is a serious problem and can lead to permanent damage to the eye. Treatment for mild cases includes switching the patient to glasses or another type of contact lens. Severe cases, however, may require corneal transplantation.

Your tears will be dry and your contacts may 'roll' up your eyes, kinda like if you fall asleep with them on and then you have to locate them when you awake on your eye. I have contacts and I've had surgery, think of your surgery as if you are taking a heavy nap.

Try AMO Complete solution. You should check with your eye dr. before resuming contact lens wear though.

Cataracts & Vision - Carnosine and N-Acetylcarnosine Eye Drops\nCategories\nHealth through Nutrition\n(http://www.newmediaexplorer.org/chris/2006/03/16/cataracts_vision_carnosine_and_nacetylcarnosine_eye_drops.htm)\nPractical Health\n\nFurther to Cataract - MSM eye drop solution the following provides more information. Although it too discusses some animal data more importantly it also includes some good human clinical data. \n\nEarly cataract is also am indication of calcium overload and sometimes IV EDTA chelation can also reverse it.\n\nI can't emphasis the importance of non processed and low carbohydrate diets for all health conditions...,\n\nSee also: \n\nAvoiding Visual Degeneration\n\nAspartame and Vision Degradation\n \nChris Gupta\n\n---------------------\nCarnosine and N-Acetylcarnosine Eye Drops (original is here)\n\nNew Hope for Cataracts \nWard Dean, MD \n\nCataracts are the leading cause of blindness, accounting for about 42 percent of all cases of blindness worldwide (affecting about 17 million people). Twenty-eight thousand new cases are reported everyday. About 20 percent of all people over 60 have at least the beginning of a cataract in one or both eyes, and that figure rises to 80 percent for people over 75. \n\nThe most common type of cataract ­ a nuclear cataract ­ is characterized by a cloudy haze inside the lens (Fig. 1). This haze is the physical manifestation of a random clumping together of the once beautifully ordered arrangement of lens proteins called crystallins. As the cataract develops in size and density, it reduces the amount of light that passes through the lens and scatters the light that does get through. Thus, instead of all the light rays being focused precisely to a point on the retina, forming a sharp, clear image of what we are seeing, many of the rays are spread out across the retina, forming a fuzzy image. Colors may be dulled or distorted, and there may be an annoying halo of light around bright objects, causing a glare effect.\n\nCauses of Cataracts \nCauses of cataracts include cumulative ultraviolet radiation damage from sun exposure, heredity, poor nutrition, smoking, high blood pressure, kidney disease, diabetes, and the long-term use of corticosteroids (the last two are major risk factors for cataracts). Oxidative free radicals produced by the above-listed causes are thought to damage vital biomolecules, including lipids and proteins, resulting in the clumping together of these proteins. The antidote to free radicals, of course, is antioxidants, such as glutathione, lipoic acid, and vitamins C and E. Consequently, many scientists believe that abundant consumption of antioxidants may delay the onset of cataracts. \n\nNutrients for Vision \nGood nutrition is a key element of effective prevention for most age-related diseases, and cataracts are no exception. A number of nutrients can benefit our eyes, and may help prevent diseases such as cataracts, glaucoma, and macular degeneration. These nutrients include the tripeptide glutathione (the most abundant and important antioxidant in the human body, critical for protecting the lens from free radical damage); vitamins A and C; vitamin E and some of the B vitamins; various bioflavonoids (especially quercetin and hesperidin) and carotenoids (especially lutein and zeaxanthin); the amino acids taurine, N-acetylcysteine (a precursor of glutathione), and acetyl L-carnitine; the hormone melatonin; the alkaloid vinpocetine; the herbs bilberry, ginkgo, and garlic; the minerals zinc and selenium; and, last but certainly not least, the saturated fatty acid, lipoic acid (“the antioxidant’s antioxidant”), which plays a central role in maintaining the body’s antioxidant network.[1] \n\nCarnosine for Vision \nCarnosine ­ a dipeptide consisting of two amino acids (alanine and histidine) connected to each other by a chemical bond called the peptide bond ­ is one of the most exciting anti-aging nutrients that has recently become widel

Overnight Monthly-wear contact lenses. They're one-way oxygen permeable.

I don't think so.  I have terrible eyesight.  I can't even see the big\n"E" on the eye chart!  I am very nearsighted.  I am in my mid 30's and have had the same prescription for several years now.\nI think it's because I do as much reading as possible without my glasses and I don't wear contacts anymore.  My sister, on the other hand, gets a new prescription every year and it's always worse.  I have heard of some kind of eye exercises advertised on the radio that supposedly restore at least some sight.  I'm sorry I can't be more specific.

Yes, it's usually one year.  The reason for this is so that your doctor can re-evaluate your vision and the fit of the contacts each year.  It's also so that he/she can make sure your eyes are healthy and that the contacts aren't causing any problems with your eyes.

I agree with what the others said.  I've had disposable contacts for years and love them.  Their really easy to handle, easy to use and you can usually find good deals online.  Just be sure you follow the doc's advice, ALWAYS wash your hands before handling and change them out regularly.  \n\nA lot of people build up protein in their eyes so after awhile the contacts get all gunked up...technical term :) .  But you don't have to worry about that with disposables unless you wear them too long, but you'll know it because they'll start to feel weird.  \n\nI wear Acuvue 2's and normally you can't even feel them when they're in.  When I start to feel something or they start bugging my eyes, it's time for a fresh pair.\n\nHope that helps.  This site might help too.\n\nhttp://www.contactlensbuyersguide.com\n\nGood luck!

I have not had it but I am very familiar with it. It is usually caused by over wearing your contacts and not cleaning them well. your doctor should have you out of them for a couple weeks and probably on a drop to help resolve it quicker.

No, you have a different eye exam for contacts, so the same script wouldn't work  -  it's a different type.

Absolutely!  I just had it in Feb and it's the most amazing thing in the world to be able to see normally without glasses or contacts.  Do your research first and find a board certified surgeon - this is not the time to look for sale prices.  There is nothing to be scared of, it does not hurt at all and it's done in like 2 minutes per eye.  Good luck!

I am an Ophthalmology nurse and have great experience with alot of these things.  First of all, no Ortho K will not correct your vision. On top of that, by sleeping in any kind of lenses, your at greater risk for a corneal ulcer, which is extremely painful, and can damage your cornea enough to cause blindness.  Lasik surgery is a very good option if you are a candidate.  It is painless.  If you wear contacts, you have to be out of contacts for three weeks because they cause corneal warpage and you could have inaccurate results.

Oral contraceptives increase your risk of blood clots. A small blood clot that forms in the left side of your heart can commonly go to the arteries that supply the eyes causing central retinal artery occlusion(CRAO) or branch retinal artery occlusion(BRAO).\n\nThis is usually the reason women on birth control pills are cautioned to be aware of vision changes.\n\nI can't think of (nor find any documentation of) a reason they would affect contact lens wear though...

Yes you can have eye tumours\nhttp://eyetumor.wustl.edu/about%20eye%20tumors.htm\n\nYour symptoms sound more like tension headaches but the safe thing would be to have a check up. See your doctor/GP or an ophthalmologist/eye specialist
