Before and after cataract surgery

How to prepare for cataract surgery, what happens on the day, and what to watch for while you recover.

This page gives general information. The written instructions you receive before and after surgery always take priority.

Before surgery

  • At the pre-operative visit your eye is measured (biometry) and the intraocular lens is chosen together with you.
  • Tell your doctor about all your medicines, especially blood thinners and prostate medicines. Do not stop any medicine without asking first.
  • If you have diabetes or high blood pressure, make sure they are well controlled.
  • If you wear soft contact lenses, ask how long to leave them out before the measurements.

On the day

  • Do not wear make-up or face cream.
  • Bring someone who can take you home; do not drive that day.
  • Whether you need to fast depends on the type of anaesthesia; you will be told in advance.
  • The operation is usually done under anaesthetic eye drops, takes a short time, and you go home the same day.

After surgery

  • Use your eye drops at the times and for as long as prescribed. If you have more than one, wait a few minutes between them.
  • Do not rub or press on the eye. Wear the protective shield at night if advised.
  • In the first days, keep water, soap and shampoo out of the eye. Avoid pools, the sea and steam rooms for as long as your doctor advises.
  • Reading, watching TV and walking are usually fine from the next day. Ask before lifting heavy objects, bending down or exercising.
  • Mild stinging, watering and light sensitivity are common at first; vision usually clears within a few days.
  • A new glasses prescription is usually given a few weeks later, once the eye has fully healed.

Follow-up visits

Check-ups are usually the day after surgery, within the first week and within the first month. Please attend them even if you feel well.
