We help to maintain vision through regular VisionSafe Eye Checks


Are you over 40 and haven’t had a comprehensive eye check done in the last year? A VisionSafe Eye Check can spot cataracts to see if you need cataract surgery


Cataract surgery overview

The cataract surgery operation involves an eye surgeon replacing the misty natural lens (cataract) with an artificial lens called an intraocular lens (IOL). Ophthalmologists perform about 30,000 cataract operations annually in the UK alone. If you are concerned that you have a cataract, you’re welcome to visit us for a VisionSafe Eye Check to get a diagnosis.

How does cataract surgery help you?

Cataract surgery will improve your vision as long as you do not have any other ocular conditions affecting your vision. To learn more about how cataract surgery works, see below.

How does cataract surgery work?

Cataract surgery is a day case procedure. That is, cataract surgery is normally a procedure under local anaesthetic, meaning you can return home the evening after your surgery. Modern cataract surgery is a form of keyhole surgery in which the natural lens is removed through a 3.5mm (and sometimes smaller) valve incision. 3.5mm is less than the width of your little finger nail. High-frequency ultrasound energy is delivered through a probe which is used to break apart and liquefy the cloudy natural lens. This is a process called phacoemulsification. Once the original lens material is broken down, it is washed out of the eye. Now a flexible new lens can be folded up in order to be gently delivered into the eye, through that small 3.5mm incision. Once inside the eye, the new lens is unfolded within the eye, and positioned to lie in the same natural position as the original lens so that it can focus light accurately on the retina. The small incision used in modern cataract surgery is almost always self-sealing i.e. no stitches are required, and your eye heals quickly.
