TOP 15 QUESTIONS ENCOUNTERED AT THE CLINIC
What are the symptoms of a cataract?
The most common symptoms of a cataract are:
• Cloudy or blurry vision.
• Colors seem faded.
• Glare. Headlights, lamps, or sunlight may appear too bright. A halo may appear around lights.
• Poor night vision.
• Frequent prescription changes in your eyeglasses or contact lenses.
• These symptoms also can be a sign of other eye problems. If you have any of these symptoms, check with your ophthalmologist.
What is glaucoma?
Glaucoma is a group of diseases in which the pressure inside the eye is raised to the extent that it can damage the eye's optic nerve and result in vision loss and blindness. However, with early detection and treatment, you can often protect your eyes against serious vision loss.
Can I develop glaucoma without increase in my eye pressure?
Yes. Glaucoma can develop without increased eye pressure. This form of glaucoma is called low-tension or normal-tension glaucoma. It is not as common as open-angle glaucoma.
Can glaucoma be treated?
Yes. Immediate treatment for early stage, open-angle glaucoma can delay progression of the disease. That's why early diagnosis is very important. Glaucoma treatments include medication, laser, conventional surgery, shunt tubes or a combination of any of these. While these treatments may save remaining vision, they do not improve sight already lost from glaucoma.
What are floaters?
As people age, the vitreous liquefies and tends to shrink. Shrinkage can then cause some traction or pulling of the vitreous on the retina. When this happens, most of the time the vitreous will separate from the retina and optic nerve cleanly. This separation is called a posterior vitreous detachment, or PVD. As the vitreous ages and liquefies, it also changes in consistency and becomes stringy and forms strands. These strands float in the vitreous and cast shadows on the retina. The patient sees them as cobwebs, spiders, or as a series of irregular fine lines in the vision. Since these particles appear to move or "float" in the field of vision they are referred to as floaters.
What is Diabetic Retinopathy?
Diabetic Retinopathy occurs when diabetes affects small blood vessels of the retina. It can cause the blood vessels to leak or become blocked. This may affect sight most frequently due to macular edema or ischemia. Bleeding inside the eye and retinal detachment involving the macula are other causes of vision loss due to diabetic retinopathy.
Is using a computer harmful to the eyes?
Although using a computer is associated with eyestrain and dryness, it is not harmful to the eyes.
When should my son/daughter have his/her first eye exam?
At any time if there is suspected problem. Otherwise a guideline is a general exam at 3 years of age.
What are the symptoms of dry eye?
Dry eye symptoms may include any of the following:
• Stinging or burning of the eye
• A sandy or gritty feeling as if something is in the eye
• Episodes of excess tears following very dry eye periods
• A stringy discharge from the eye
• Pain and redness of the eye
• Episodes of blurred vision
• Uncomfortable contact lenses
• Decreased tolerance of reading, working on the computer, or any activity that requires sustained visual attention.
What happens before laser eye surgery?
Your ophthalmologist will give you a thorough eye exam to make sure your eyes are healthy and you're a suitable candidate for laser vision correction. He or she will test for glaucoma, cataracts and other disqualifying conditions. He or she also will use a machine called a corneal topographer to photograph and electronically map your eye. The surgeon will use this map to plan your surgery for the most precise results possible.
When may I resume driving?
You may begin driving as soon as you see well enough, excluding the day you had LASIK or PRK performed.
Can LASIK or PRK fix astigmatism?
Yes, in most cases, and the effect is permanent. Astigmatism is a very common vision problem. Despite having a somewhat scary-sounding name, astigmatism is not an eye disease - it's simply a refractive error like nearsightedness and farsightedness.
When should I stop wearing contact lenses before LASIK or PRK?
Individual surgeons may have different preferences regarding when you should discontinue contact lens wear prior to LASIK surgery. But generally, most surgeons say you should stop wearing soft contact lenses at least one week prior to surgery. If you wear rigid gas permeable contact lenses, you should stop wearing these lenses for a longer period of time prior to LASIK - generally a month or longer.
What is cataract?
A cataract is a clouding of the lens in the eye that affects vision. Most cataracts are related to aging. Cataracts are very common in older people. By age 80, more than half of all people either have a cataract or have had cataract surgery. A cataract can occur in either one or both eyes, though one eye may advance faster than the other. It cannot spread from one eye to the other.
What are intraocular injections?
These are injections given into the eye to reduce retinal thickening due to fluid collection as well as to control bleeding in advanced retinopathy. After the injection, you will be monitored for any increase in eye pressure or infection. Depending on your eye condition, you may require repeated injections.
