A cataract clouds the lens of the eye causing vision loss that interferes with daily activities. The only effective means of restoring vision is to perform surgery to remove and replace them with permanent artificial lenses.
Phacoemulsification Cataract Surgery which is regularly done in Jai Drishti Eye Hospital, Udaipur is the most modern and safe technique for cataract surgery. Phacoemulsification, or phaco is method of cataract surgery in which the eye’s internal lens is emulsified using ultrasonic energy and replaced with an intraocular lens implant or IOL.
Phaco surgery is performed with a small ultrasonic probe inserted into the eye via a 2 to 3 mm incision. This probe breaks the cloudy lens into tiny pieces and sucks the fragments out of the eye. Than a permanent foldable artificial lens (called an intraocular lens or IOL) is inserted. Surgery is performed under a local anesthesia to prevents movement of the eye.
The patient is advised to rest for at least 24 hours, until he or she returns for follow-up. Only light meals are recommended on the day of surgery. The patient may experience some eye pain or discomfort. Usually, over-the-counter medications are advised for pain relief, but patients should check with their doctors.
Patients are advised to wear an eye shield while sleeping, and refrain from rubbing the eye for at least two weeks. During that time, the doctor will give the patient special tinted sunglasses. Unlike other types of cataract extraction, patients can resume normal activity almost immediately after phaco.
Subsequent exams are usually at one week, three weeks, and six to eight weeks following surgery. This can change, however, depending on any complications or any unusual postoperative symptoms.
After the healing process, the patient will probably need new corrective lenses, at least for close vision. While IOLs can remove the need for myopic correction, patients will probably need new lenses for close work.
