phacoemulsifikaatio

Phacoemulsification is a surgical procedure used to remove the natural lens of the eye and replace it with an artificial intraocular lens (IOL). This technique is commonly employed in cataract surgery, which is the most common cause of blindness in the developed world. The procedure is performed under local anesthesia and typically takes about 15-20 minutes.

The process begins with the surgeon making a small incision in the cornea, the clear front surface of the eye. A phacoemulsification probe is then inserted into the eye through this incision. This probe emits ultrasonic waves that break down the cataract into small fragments, which are then suctioned out of the eye.

Once the cataract is removed, the surgeon inserts the artificial IOL into the eye. The IOL is designed to restore vision by focusing light onto the retina. The incision is then closed, and the patient is typically discharged the same day.

Phacoemulsification is preferred over other cataract removal techniques because it is less invasive, causes less trauma to the eye, and results in a faster recovery time. It is also associated with a lower risk of complications such as infection and retinal detachment. However, it may not be suitable for all patients, particularly those with certain types of cataracts or eye conditions. In such cases, alternative surgical techniques may be used.
