What it is
Some people have both a cataract (a cloudy natural lens) and glaucoma (damage to the optic nerve, often linked to raised eye pressure). In combined surgery, the cataract is removed and replaced with a clear artificial lens, and a glaucoma procedure — such as trabeculectomy — is done in the same operation to help lower eye pressure.
Who it's for
Selected patients with both a cataract and glaucoma when both conditions need surgery, as advised by the doctor after a full examination.
What to expect
Before surgery, your eye is measured to choose the lens implant, and your eye pressure, drainage angle and optic nerve are assessed. The operation is usually done under local anaesthesia. Your doctor will advise whether you go home the same day.
Recovery
You will use prescribed drops and attend frequent follow-up visits in the first weeks to check your eye pressure and healing. Avoid rubbing the eye, bending, heavy lifting, and dust or water in the eye for as long as advised. Report increasing pain, redness or a drop in vision straight away.
Frequently asked questions
Why have both procedures together?
When both conditions need surgery, combining them means one operation and one recovery period instead of two. Your doctor will advise whether it suits your eyes.
Will my vision improve?
Removing the cataract can improve vision, but vision already lost to glaucoma cannot be restored. The glaucoma part of the operation aims to protect the sight you have.
