Phacoemulsification

Phacoemulsification surgery being performed on a patient.

Phacoemulsification

Phacoemulsification is a modern cataract surgery technique in which the eye's internal lens is emulsified with an ultrasonic handpiece and then aspirated from the eye. This process is followed by the insertion of an intraocular lens (IOL) to replace the natural lens.

Overview

Cataract, the clouding of the eye's natural lens, is one of the leading causes of blindness globally. Phacoemulsification offers a less invasive method to remove the clouded lens, allowing for faster recovery and reduced complications compared to traditional cataract surgery methods.

Procedure

• Incision: A small incision is made on the cornea.
• Capsulorhexis: A circular opening is created on the anterior capsule of the lens to access the cataract.
• Emulsification: The ultrasonic handpiece is used to break the cataract into small pieces.
• Aspiration: The fragmented cataract is then aspirated out of the eye.
• IOL Insertion: An intraocular lens is folded and inserted through the incision, then it unfolds and takes the place of the natural lens.

Advantages

• Smaller Incisions: This reduces the risk of complications and speeds up healing.
• Quick Recovery: Most patients can resume normal activities shortly after the procedure.
• No Stitches: Due to the small incision size, stitches are often not required.

Risks

While phacoemulsification is generally safe, potential complications can include:

• Infection or bleeding.
• Swelling or fluid buildup in the retina (macular edema).
• Posterior capsule opacity, also known as secondary cataract.

Equipment

Phacoemulsification requires specialized equipment, including:

• Ultrasonic handpiece.
• Aspiration pump.
• Specialized IOLs and insertion devices.

Post-Operative Care

After the procedure, patients may be prescribed:

• Antibiotic eye drops to prevent infection.
• Anti-inflammatory eye drops to reduce swelling.
• Protective eyewear to shield the operated eye from potential trauma.
