Cataract surgery phacoemulsification (phaco) is used to restore vision in patients whose vision becomes cloudy from cataracts as the basis for writing his article.
Cataract surgery phacoemulsification
When you are 50 years old and above, most of us tend to have cataracts. Cataracts are usually just normal symptoms of the aging process. Cataracts are lens opacities in the eye, causing vision loss that cannot be corrected with glasses, contact lenses or corneal refractive surgeries such as LASIK. Although cataract sounds scary, modern cataract surgery can usually restore vision and can reduce dependence on glasses. Modern cataract surgery is one of the safest and most effective surgical procedures performed today. More than three million cataract surgeries are performed and most of these procedures produce excellent visual results.
Phacoemulsification cataract surgery is a procedure in which an ultrasonic device is used to break down and then remove a cloudy lens (cataract) from the eye to improve vision. Intraocular lens insertion (IOL) usually follows phacoemulsification immediately. Phacoemulsification (phaco) is used to restore vision to patients whose vision becomes cloudy from cataracts. In the first stage of cataracts, people may only see a little turbidity that affects a small portion of the lens. The lens is a part of the eye that focuses light on the retina. When cataracts grow, it prevents more light and vision from becoming more gloomy. As vision worsens, the surgeon will recommend cataract surgery, usually phaco, to restore clear vision. With advances in cataract surgery such as IOL patients can sometimes experience dramatic vision improvements.
In cataract surgery, the lens inside the eye that has become cloudy is removed and replaced with an artificial lens (intraocular lens or IOL) to restore clear vision. Most modern cataract procedures involve the use of a high-frequency ultrasound device that breaks the cloudy lens into small pieces, which are then gently removed from the eye by suctioning. This procedure, called phacoemulsification or “phaco”, is performed with a smaller incision than the previous surgical technique to eliminate cataracts, promote faster healing and reduce the risk of complications of cataract surgery such as retinal detachment. After all the remaining cloudy lenses have been removed from the eye, the cataract surgeon inserts an intraocular lens and positions it safely behind the iris and pupil. The surgeon then completes the cataract removal procedure and IOL implantation by closing the incision in the eye with a protective shield placed above the eye. A protective shield is used to keep it safe in the early stages of your cataract surgery.
Cataract surgery is carried out on an outpatient basis, so the patient must arrange for someone to take him home after surgery. On the day of surgery, the doctor will review the pre-operative tests and include dilated eyedrops, antibiotic drops and corticosteroids or nonsteroidal anti-inflammatory drops. Anesthetic eyedrops will be given in both eyes to keep both eyes comfortable during surgery. Local anesthesia will be given. The patient is awake for surgery, but is kept relaxed. The complications are not possible, but can occur. The patient may experience spontaneous bleeding from recurrent wounds and inflammation after surgery. Blinking, floaters, and double vision can also occur several weeks after surgery. The surgeon must be immediately informed of these symptoms. Some can be easily treated, while others such as floaters may be a sign of retinal detachment. Most patients have recovered visual acuity after surgery, and some patients will have the best vision about their lives after IOL insertion. Some patients no longer need the use of glasses or contact lenses after cataract surgery. Patients will also have better color and depth perceptions and can continue their normal activities may have stopped due to visual disturbances from cataracts, such as driving, reading, or sports.
