In cataract surgery, the lens inside your eye that has become cloudy is removed and replaced with an artificial lens (called an intraocular lens, or IOL) to restore clear vision. Cataract surgery will restore the clarity of vision, and vibrancy of colors, that you experienced years earlier.
The health of your macula is paramount. The macula is at the center of your retina, in the back of the eye, and it's important to good vision and long-term eye health in two ways.
First, optimizing your macular pigment improves contrast sensitivity and your overall quality of vision. That aids in color perception and low-light situations.
Second, for the long term, preserving the health of your macula is key to prevention of macular degeneration, the major cause of blindness in older Americans.
The procedure typically is performed on an outpatient basis and does not require an overnight stay in a hospital or other care facility.
Most modern cataract procedures involve the use of a high-frequency ultrasound device that breaks up the cloudy lens into small pieces, which are then gently removed from the eye with suction.
This procedure, called phacoemulsification or "phaco," can be performed with smaller incisions than previous surgical techniques for cataract removal, promoting faster healing and reducing the risk of cataract surgery complications, such as a retinal detachment.
After all remnants of the cloudy lens have been removed from your eye, the cataract surgeon inserts a clear intraocular lens, positioning it securely behind the iris and pupil, in the same location your natural lens occupied.
The surgeon then completes the cataract removal and IOL implantation procedure by closing the incision in your eye (a stitch 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 recovery.
Surgery reduces the pressure in the eyes by opening blocked drainage angles or creating a new opening that fluid can flow through to leave the eye. In some cases surgery may be done to relieve pain caused by glaucoma.
Doctors can use either a surgical cutting tool or a very focused beam of light, called a laser, to do surgery for glaucoma. Laser surgery is usually the first type of surgery tried. If laser surgery doesn't help, your doctor may try conventional surgery.It is not unusual for some people to have both open- and closed-angle glaucoma. They may need more than one kind of procedure
LASIK, which stands for laser in-situ keratomileusis, is a popular surgery used to correct vision in people who are nearsighted, farsighted, or have astigmatism.All laser vision correction surgeries work by reshaping the cornea, the clear front part of the eye, so that light traveling through it is properly focused onto the retina located in the back of the eye. LASIK is one of a number of different surgical techniques used to reshape the cornea.
