Just like the lens of the camera focuses light on the film, the lens of your eye focuses light on the back part of the eye or retina. If the front of your cameras lens becomes dirty or fogged, then the pictures taken will be hazy.
A Cataract is a clouding of the normally clear lens of the eye. This clouding, usually due to a natural aging of the lens, prevents light from passing clearly through the lens to the retina.
If you've noticed blurring and haziness in your vision, you may be developing cataracts. Other common symptoms of cataracts are dimming of near and/ or distant vision as well as glare, yellowish discoloration of vision, and dazzling effects.
How to treat Cataracts?
Because the only way to restore clear vision for someone with a cataract is to surgically remove the cloudy lens, the lens is then replaced with a clear plastic lens implant. At Laser Vision, the technique used is called Phacomulsification, an advanced and painless method of cataract removal.
During cataract surgery, a tiny ultrasonic probe breaks up the cataract and draws it away. Because the incision required is only about an eight of an inch, this technique is often called small-incision surgery. It encourages rapid healing, less astigmatism, and a fast return to full activity.
The new lens remains permanently in place and is neither seen or felt by the patient. The lens restores the most natural vision available as well as good depth perception and full peripheral vision.
Cataract should be removed when your vision has worsened to the point that they interfere with your lifestyle and you are no longer able to comfortably do the things you enjoy such as reading, working, or driving. Ultimately, the final decision to have surgery must be yours, based on the information you receive and the impediments you experience due to your cataract.
The YAG Laser
One important instrument in providing modern after cataract care is YAG Laser. Although lasers cannot be used to treat cataract, they are helpful when secondary cataracts develop. In these cases, the clear capsule within the eye which holds the new artificial lens becomes cloudy. The YAG Laser uses light rays to make a small opening in the capsule right in the office painlessly and without traditional surgery. This opening restores good vision by allowing the light rays to focus clearly on the retina again. The procedure is required in about 20% of prior cataract patients, is only performed once, and takes only a few minutes with on restrictions afterwards.
After the surgery, you will be seen on the clinic to ensure that you are healing properly. Typically, these visits occur 1 day, 1 week, and then 1 month after surgery. During this time, you will also be using eyedrops to help the eye to heal.
On the next day after the surgery, your eye patch will be removed, and you can often begin using the eye. The vision is usually blurred from ointments and from swelling associated with the surgery, but over the following weeks, the vision will usually progressively improve. At one month after the surgery, the eye is typically healed and ready for a refraction for new glasses.
