Uveitis
Uveitis is inflammation affecting one or more parts of the uveal tract inside the eye. It may affect the front, middle or back of the eye, or involve all three areas.

YAG laser capsulotomy
After cataract surgery, the thin membrane supporting the new lens can become cloudy. This may make vision misty again. YAG laser capsulotomy makes an opening in that membrane.
YAG laser peripheral iridotomy
Laser peripheral iridotomy makes a small opening near the edge of the iris, the coloured part of the eye. It is used to treat or help prevent angle-closure glaucoma.
