Cataract surgery ultrasound is usually done by making incisions smaller than previous surgical techniques to eliminate cataracts, promote faster healing and reduce the risk of complications of cataract surgery, such as retinal detachment.
Cataract Surgery Ultrasound
Sometime after the age of 50, most of us tend to hear our eye doctor say, “You have cataracts.” Cataracts are the opacity of the lens inside the eye, causing loss of vision that cannot be corrected with glasses, contact lenses or corneal refractive surgery like LASIK. Although cataracts are frightening, modern cataract surgery can usually restore lost vision in cataracts and can often reduce your dependence on glasses as well. Most cataracts are associated with the aging process and are common among older Americans. In fact, according to the National Eye Institute (NEI), 68.3 percent of 80 and older Americans have cataracts in 2010. Modern cataract surgery is one of the safest and most effective surgical procedures performed today. More than three million cataract operations are performed in the United States each year, with most of these procedures producing excellent visual results.
In cataract surgery, the lens inside your cloudy eye is removed and replaced with an artificial lens (called an intraocular lens, or IOL) to restore clear vision. Most modern cataract procedures involve the use of a high-frequency ultrasound instrument that breaks the cloudy lens into small pieces, which are then gently removed from the eye by suction. This procedure, called phacoemulsification or “phaco,” can be performed with smaller incisions than previous surgical techniques to remove cataracts, promote faster healing and reduce the risk of complications of cataract surgery, such as retinal detachment. The surgeon then completes the procedure of cataract removal and IOL implantation by closing an incision in your eyes (stitches may or may not be needed), and a protective shield is placed over the eye to keep it safe in the early stages of your cataract surgery.
Recently, a number of femtosecond lasers are similar to lasers used in cataract surgeries performed in the United States. Femtosecond laser-assisted cataract surgery (FLACS) provides better visual results with less eye trauma than conventional cataract surgery. This procedure only takes a few minutes and is completely painless; also no discomfort after surgery. Although studies have shown that lasers can improve accuracy during certain steps of cataract surgery, they may not necessarily improve the safety of cataract surgery, recovery time and visual results in each case.
Before the cataract surgery, your ophthalmologist will perform a comprehensive eye exam to check your overall eye health, evaluate whether there is a reason why you should not have surgery and identify any risk factors you may have. Refraction will also be made to accurately determine the number of farsightedness or astigmatism that you had before surgery. Additional measurements of your eyes will be taken to determine the curvature of your cornea and the length of your eyes. This measurement is very important to help your cataract surgeon choose the power of the right intraocular lens and give you the best vision after surgery.
Uncomplicated cataract surgery usually lasts only about 15 minutes. However, you should be in the surgical center for 90 minutes or more, as extra time is required to prepare your surgery (dilate your pupil, preoperative medication) and for a brief after-life evaluation and instructions on restoring your cataract surgery before you are allowed to go home. Next you will be prescribed eye-drops for use several times every day for several weeks after cataract surgery. You should also wear eye protection when you sleep to avoid sun and other bright light about a week after surgery. At least during the first week of your recovery you should avoid: Weight and weight lifting (no more than 25 pounds). Bending, exercising, and similar activities that may make you stress when healing. Water that may enter your eyes and cause infection. Keep your eyes closed when bathing or bathing. In addition, you avoid swimming or hot tub for at least two weeks. As a remedy step, you should also avoid any eye activity from dust, dirt or other infectious contaminants.
If you need cataract surgery in both eyes, your surgeon will usually prefer you to wait one to three weeks between procedures, so your first eye has healed enough and you have good eyesight in that eye before the second operation is done. If you have any questions or concerns about cataract surgery, be sure to discuss it with your ophthalmologist and cataract surgeon before performing the surgery.
