Cataracts Sacramento California Cataracts

LASIK is now the vision correction procedure of choice for many ophthalmologists worldwide. Instead of removing the surface epithelium with the laser and exposing many nerve endings (as in PRK), the surgeon performing LASIK uses a motor-powered microkeratome to create a "flap." The flap is then lifted and reflected back, allowing a computer guided Excimer laser (cold laser) to use light pulses to remodel the corneal tissue underneath. Afterward, the flap is gently positioned back onto the cornea. Since this procedure is less traumatic to the outer surface of the eye, vision is restored more quickly and the patient's discomfort is reduced. Most patients report greater comfort after surgery and can generally drive two to three days after the surgery.

A cataract is a clouding of the normally clear lens of the eye. Cataracts occur in every eye as we age. Common symptoms of cataracts include: painless blurring of vision; glare, light sensitivity; poor night vision; double vision in one eye; needing brighter light to read; fading or yellowing of colors. How quickly a cataract develops varies among individuals, and may even be different between the two eyes. Most age-related cataracts progress gradually over a period of years; average age people come to have surgery is 74 years old. Other cataracts, especially in younger people and people with diabetes, may progress rapidly over a short time. It is not possible to predict exactly how fast cataracts will develop in any given person.

Surgery is the only way a cataract can be removed. However, if symptoms of cataracts are not bothering you very much, surgery may not be needed. Sometimes a simple change in your eyeglass prescription may be helpful. Surgery should be considered when cataracts cause enough loss of vision to interfere with your daily activities, such as driving at night or in bright sunlight. There are no medications, dietary supplements or exercises that have been shown to prevent or cure cataracts.
