Phacoemulsification: modern cataract surgery

Phacoemulsification (often called “phaco”) is the current standard technique for cataract surgery. The cloudy natural lens is gently broken up using ultrasound energy and removed through a very small opening, and a clear artificial lens (intraocular lens, or IOL) is placed in its position. Because the incision is tiny, most patients need no stitches and recover quickly.

Who needs it

Phacoemulsification is appropriate when a cataract has progressed enough to affect daily activities such as reading, driving or recognising faces. The decision is individual — we recommend surgery when the benefit to your vision and quality of life clearly outweighs leaving the cataract alone.

What to expect

• A day-care procedure, usually completed in well under an hour
• Performed under local (often topical drop) anaesthesia
• A small, self-sealing incision — typically no stitches
• A clear IOL chosen to suit your eyes and visual needs

Benefits

• Small incision and faster visual recovery
• Performed as day care — home the same day
• Long-established, well-studied technique

Risks and limitations

All surgery carries some risk. Cataract surgery is among the most commonly performed and well-studied operations, but possible issues include inflammation, infection, raised eye pressure or a need for spectacles for some tasks. We discuss your individual risks honestly before you decide.

Recovery

Most people resume light activities within a day or two, following the eye-drop schedule and precautions we provide. We review you after surgery to confirm healing is on track.

Lens choice

The type of IOL matters as much as the surgery. See Premium IOL options to understand monofocal, toric and multifocal lenses — and which suits your eyes and lifestyle.

Frequently asked questions

Is phaco better than older cataract surgery?

For most eyes, the small-incision phaco technique offers faster recovery than older large-incision methods. The right approach still depends on your specific cataract, which we assess individually.

Will I still need glasses afterwards?

It depends on the lens chosen and your eyes. Some patients reduce their dependence on glasses; others still need them for certain tasks. We set realistic expectations before surgery.
