Cataract is a medical condition in which the natural lens of the eye becomes progressively opaque, resulting in blurred vision. Hence cataract surgery is done for extracting this natural lens from the eyes of the affected person. It is then replaced with an artificial intraocular lens (IOL).
Phacoemulsification and extracapsular cataract extraction are two techniques for correction of cataract. Out of these, phacoemulsification is the commonly used process. In case of certain eye complication, extracapsular cataract extraction might be required.

The lenses which are used to treat this condition are called unifocal lenses. These lenses provide only one point of focus to the eyes.
In case of phacoemulsification, a local anesthetic is administered before the incision in the eye is made. Post incision, an intraocular lens (IOL) is inserted into the eye. The surgery typically lasts for 30-45 minutes.
Post operation, patients are supposed to use the eye drops prescribed by the medical professional and refrain from contact of water or soap into the eyes. The patient should also avoid touching or rubbing his or her eyes. Most people need to wear glasses for near or distance vision-or-both after cataract surgery.
Contact your doctor immediately if you experience any of the following:
Loss of vision, persistent pain even after taking pain-killers, queasiness, redness of eyes, flashes of light, puking and cough. In case of multiple cataracts, the doctor schedules two surgeries keeping a gap of a month in between.
