phakoemulsification

Phacoemulsification is a modern surgical technique used to remove cataracts. A cataract is a clouding of the eye's natural lens, which can impair vision. This procedure involves using an ultrasonic device to break up the clouded lens into small pieces. These fragments are then gently suctioned out of the eye.

The process typically begins with a small incision made in the cornea, the transparent outer layer of the eye. Through this incision, a tiny phacoemulsification probe is inserted. The probe emits high-frequency ultrasound waves that emulsify, or break down, the cataractous lens. Simultaneously, irrigation and aspiration are used to remove the emulsified fragments and maintain the eye's internal pressure.

Once the natural lens is removed, it is usually replaced with an artificial intraocular lens (IOL). This IOL is carefully selected based on the patient's visual needs and is implanted in the same capsule where the natural lens was located. Phacoemulsification is known for its safety and effectiveness, generally resulting in a rapid recovery and improved vision for patients. The small incision size also contributes to a quicker healing process and reduced risk of complications compared to older cataract removal methods.
