Phacoemulsification Surgery in Pune

Phacoemulsification What happens during a phacoemulsification procedure? What is the recovery from a phacoemulsification procedure? Phacoemulsification is a modified version of extracapsular cataract extraction (ECCE) and is the most common surgical procedure for removing cataracts. As in other forms of ECCE, phacoemulsification involves removing the eye's natural lens while leaving in place the back of the capsule, which holds the lens in place. The difference with phacoemulsification is that the cataract is broken into tiny pieces that are suctioned from the eye through a smaller incision than that required by other forms of cataract surgery. Healing and rehabilitation are faster with this procedure, and there is little, if any, discomfort. To understand how the phacoemulsification technique works, it is important to understand what a cataract is and how it interferes with vision. The eye works like a camera with two lenses. The first lens is thecornea, a clear membrane that covers the front of the eye. The second lens is the eye's natural crystalline lens, which is held in place by a capsule located behind the pupil (See Anatomy of the Eye). The cornea is responsible for about 70 percent of the eye's focusing power, while the natural lens fine-tunes the image. When the natural lens becomes cloudy, usually because of the aging process, it keeps light rays from passing through or diffuses the light in such a way that vision becomes fuzzy or hazy. This cloudy lens is called a cataract. The object of cataract surgery is to remove this hazy lens and to replace it with a plastic prescription lens that is permanently implanted in the eye. What happens during a phacoemulsification procedure? In phacoemulsification cataract surgery, the surgeon makes a very small incision -- about 1/8th of an inch -- in the white of the eye near the outer edge of the cornea. A small ultrasonic probe is inserted through this opening and, oscillating at 40,000 cycles per minute, is used to break up (emulsify) the cataract into tiny pieces. The emulsified material is simultaneously suctioned from the eye by the open tip of the same instrument. The hard central core of the cataract (the nucleus) is removed first, followed by extraction of the softer, peripheral cortical fibers that make up the remainder of the lens. The front (anterior) section of the lens capsule is removed along with the fragments of the natural lens. The back (posterior) portion of the capsule is left in place to hold and maintain the correct position for the implanted intraocular lenses. After removal of the cataract, a prescription intraocular lens, or IOL, is permanently implanted in the lens capsule to replace the natural crystalline lens of the eye that was removed during the surgery. This lens is rolled inside a tiny hollow tube and inserted through the same incision that was used to remove the cataract. The folded lens is pushed out of the tube by a tiny plunger and, as it unfolds, is positioned by the surgeon in the center of the lens capsule. The new lens is held in place by microscopic, spring-like wires that are attached to the implant. What is the recovery from a phacoemulsification procedure? The tiny incision made during phacoemulsification surgery generally requires no stitches and heals itself in a few days. Antibiotic and steroid eyedrops may be given to diminish inflammation, to prevent infection, and to keep the eye moistened for several days following surgery. Phacoemulsification cataract surgery is one of the most effective surgical procedures performed in the United States today, and a large percentage of patients are very satisfied with the results.

A cataract is an eye disease in which the normally clear lens of the eye becomes cloudy or opaque, causing a decrease in vision. The lens focuses light onto the back of the eye (the retina) so images appear clear and without distortion. The clouding of this lens during cataract formation distorts vision. Cataracts are usually a very gradual process of normal aging but can occasionally develop rapidly. They commonly affect both eyes, but it is not uncommon for a cataract in one eye to advance more rapidly. Cataracts are very common, especially among the elderly.

Precisely why cataracts occur is unknown. However, most cataracts appear to be caused by changes in the protein structures within the lens that occur over many years and cause the lens to become cloudy. Rarely, cataracts can present at birth or in early childhood as a result of hereditary enzyme defects, other genetic disease, or systemic congenital infections. Severe trauma to the eye, eye surgery, or intraocularinflammation can also cause cataracts to develop more rapidly. Other factors that may lead to development of cataracts at an earlier age include excessive ultraviolet light exposure, exposure to ionizing radiation,diabetes, smoking, or the use of certain medications, such as oral, topical, or inhaled steroids. Other medications that may be associated with cataracts include the long-term use of statins and phenothiazines.

The total number of people who have cataracts is estimated to increase to 30.1 million by 2020. When people develop cataracts, they begin to have difficulty doing activities they enjoy. Some of the most common complaints include difficulty driving at night, reading, or traveling. These are all activities for which clear vision is essential.

What are the symptoms and signs of cataracts?

Cataract development is like looking through a dirty windshield of a car or smearing grease over the lens of a camera. Cataracts may cause a variety of complaints and visual changes, including blurred vision, difficulty with glare (often with bright sun or automobile headlights while driving at night), dull color vision, increasednearsightedness accompanied by frequent changes in eyeglass prescription, and occasionally, double vision in one eye. A change in glasses may initially help once vision begins to change from a cataract. However, as the cataract continues to become denser, vision also becomes more cloudy, and stronger glasses or contact lenses will no longer improve sight.
