Frequently Asked Questions (FAQ)
No, there is no age bar
Yes. As long as cornea (the outer transparent layer) is normal, even a blind person can donate eyes.
1. Cover the eyelids
2. Keep ice cubes on lids
3. Put antibiotic drop
4. Put A.C. on
5. Inform the eye bank
They are either stored in the moist chamber or M-K media. Once the results of blood tests of donor are available, donor cornea is assessed for its quality and utility. Good quality cornea are used for cornea transplantation (for the purpose of giving vision to someone) and others are used for research purpose.
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 Americans either have a cataract or have had cataract surgery.
A cataract can occur in either or both eyes. It cannot spread from one eye to the other.
The risk of cataract increases as you get older. Besides age, other risk factors for cataract include
1. Certain diseases like diabetes
2. Personal behavior like smoking or alcohol use
3. Environmental factors such as prolonged exposure to ultraviolet sunlight.
The most common symptoms of a cataract are
1. Cloudy or blurry vision
2. Colors seem faded
3. Glare — headlights, lamps, or sunlight appearing too bright, or a halo may appear around lights
4. poor night vision
5. Double vision or multiple images in one eye
6. Frequent prescription changes in your eyeglasses or contact lenses.
These symptoms can also be a sign of other eye problems. If you have any of these symptoms, check with your eye care professional.
The symptoms of early cataract may be improved with new eyeglasses, brighter lighting, anti-glare sunglasses, or magnifying lenses. If these measures do not help, surgery is the only effective treatment. Surgery involves removing the cloudy lens and replacing it with an artificial lens.
Yes. Cataract removal is one of the most common operations performed in the United States. It is also one of the safest and most effective types of surgery. In about 90 percent of cases, people who have cataract surgery have better vision afterward.
Glaucoma is an eye disease in which the internal fluid pressure of your eye rises to a point that the optic nerve is damaged.
The pressure that builds up is usually due to inadequate drainage of fluid normally produced in your eyes. Glaucoma is one of the leading causes of blindness in the U.S.
The exact cause of glaucoma is not known. For some reason, the passages that normally allow fluid within your eye to drain out become clogged or blocked. This results in fluid building up within your eye and increasing pressure on the optic nerve. The nerve fibers and blood vessels in the optic nerve can easily be damaged by this pressure, resulting in loss of vision.
An injury, infection or tumor in or around the eye can also cause the pressure to rise.
The optic nerve, at the back of the eye, carries visual information to the brain. As the fibers that make up the optic nerve are damaged, the amount and quality of information sent to the brain decreases and a loss of vision occurs.
If diagnosed at an early stage, glaucoma can often be controlled and little or no further vision loss may occur. If left untreated, first peripheral vision and then central vision will be affected and blindness may result.
A comprehensive optometric examination will include tests for glaucoma. A simple, painless procedure called tonometry measures the internal pressure of your eye. Your optometrist will also look into your eye to observe the health of the optic nerve and measure your field of vision.
Squint is a condition which occurs when eyes do not point in the same direction. The eyes may turn inside, outside and have dimensional differences between each other. There are four main types of strabismus;
1. Esotropia: The eye turns inside.
2. Exotropia: The eye turns outside.
3. Hypertropia: The eye turns upwards.
4. Hypotropia: The eye turns downwards.
The surgery primarily aims to pull the outer muscles of your eye in order to reposition it in the right direction. The eye is active during the operation and after the positioning process; Longevita surgeon makes the muscles stable with stitches. There is no vision loss after the operation.
Longevita surgeons usually use general anesthesia for strabismus procedures.
The squint surgery usually takes from 30 to 90 minutes.
You need to use special eye-drops to speed up the healing process and prevent a possible infection. You do not necessarily need to wear an eye patch or protective bandage. When you feel doing so, you may resume reading and watching TV again.
