Many individuals get cataracts after the age of fifty. This happens when the lens in the eye clouds and causes a loss of vision. Cataracts cannot be corrected with corneal refractive surgery, contacts or glasses. Surgery can often restore vision and decrease the need for eyeglasses. The symptoms of the best candidates are clouded vision, dim colors, blurred vision and light sensitivity. Most cataracts result from the aging process. Modern cataract surgery is a very effective and safe surgical procedure. During the surgery, the cloudy lens in the eye is removed and an artificial lens is used as a replacement. This usually restores clear vision.
Cataract surgery Nashville TN restores color vibrancy and clear vision. The macula is in the center of the retina and important for long term eye health and good vision. The quality of vision and contrast sensitivity is improved by optimizing the macular pigment. This helps in low light and color perception. The major cause of older Americans going blind is macular degeneration. The procedure is on an outpatient basis, so the patient will not have to stay in the hospital overnight. The procedure usually uses a high frequency ultrasound device so the cloudy lens can be broken into little pieces and removed using suction. This is called a phaco or phacoemulsification procedure. The incisions are small so healing is faster and complications are reduced. For additional information please visit https://en.wikipedia.org/wiki/Cataract.
Once the cloudy lens is removed, a clear intraocular lens is inserted by the surgeon. The lens is securely placed behind the pupil and iris where the natural lens was located. The incision in the eye is then closed and a protective shield used to keep the eye safe during the initial recovery period. The FDA has approved several femtosecond lasers. These are like the lasers used for LASIK to create the corneal flap. These lasers are approved for cataract surgeries in the United States. These lasers decrease the need for hand held tools and surgical blades, enable the surgeon to access the lens through a corneal incision, remove the anterior capsule and fragment the cataract.
The advances in technology have reduced the price for cataract surgery. Accuracy is also improved during surgery due to this technology. The process begins when the individual visits an ophthalmologist or optometrist for a comprehensive eye exam. The health of the eyes is evaluated, and the determination made if cataract surgery is a viable option. A refraction determines the amount of farsightedness, nearsightedness or astigmatism before the surgery. The eyes are measured for the length and cornea curvature. These measurements enable the surgeon to choose the correct power for the intraocular lens. This provides the best possible vision after the surgery. The surgeon has a wide variety of IOL’s to choose from and the choice is dependent on the needs of the individual. If the individual is not concerned about wearing glasses after the surgery, the most common implant is a monofocal lens.
