PCO is treated using a YAG laser to clear the posterior capsule. This is a straightforward and painless procedure carried out in the clinic whilst seated at a machine similar to ones you will have been examined on before and after your cataract surgery. You will have your pupils dilated and anaesthetic drops will be instilled. A specialised focussing contact lens will be placed on your eye to help focus the laser beam precisely on the posterior capsule, and which also maintains your eyelids open apart. The laser will then be used to create an opening in the capsule behind the lens, which allows all light to be transmitted again to the back of the eye, restoring your vision. The YAG procedure is very quick, lasting approximately 5 minutes per eye. You may notice an increase in floaters initially following treatment, however these normally settle, and visual clarity is usually re-established within a few days.
