Understanding Laser eye treatment (YAG laser capsulotomy)

YAG laser capsulotomy is a specialised laser treatment to improve your sight after cataract surgery.

A cataract gives a cloudy appearance in the lens at the front of the eye. This can cause visual impairment.

Cataracts are usually a result of ageing. During cataract surgery, the cloudy lens is removed from the lens capsule and replaced with an artificial, foldable lens implant to improve vision. In a small number of cases, the lens capsule in the eye can thicken after cataract surgery, reducing the amount of light that can pass through the lens to the retina. 

This can cause your sight to become cloudy or blurry and you may have a raised sensitivity to bright lights in particular.

Should this occur, YAG laser capsulotomy can be carried out to restore clearer vision.

A laser beam is used to create a small hole in the lens capsule, which allows light to pass through it again, leading to an improvement in your sight.

What is YAG laser capsulotomy?

A laser is a high-energy beam of light. A YAG laser is named after the synthetic crystal used in it (yttrium-aluminium-garnet). YAG laser capsulotomy is carried out in the ophthalmology department of St Joseph’s Hospital by one of our experienced eye consultants (ophthalmologists).

One they have explained the procedure to you, and you have asked any questions you have, they will put some eye drops into your eye to help enlarge the pupil.

This allows the doctor to see more clearly into your eye when positioning the laser. You will also be given an anaesthetic eye drop to numb the front of your eye, so that you don’t feel any pain during the procedure.

A special mirrored lens (a bit like a regular contact lens) will be placed onto the surface of your eye. This allows the doctor to see the lens capsule more clearly and helps to ensure the laser is directed at the correct point on the eye.

Once the laser is positioned in the correct place, it is shone directly into the eye to create a small hole in the lens capsule. The laser itself is invisible, but a bright light will be shone into your eye to highlight the capsule for the doctor.
