Can a person affected by narrow angle glaucoma use contact lenses?

Contacts. Patients with glaucoma can wear contacts. If glaucoma drops are being used, drops are used before the contacts are put on or after contacts are removed.
Absolutely. Glaucoma is a disease that affects the nerve inside of the eye and is treated with eye drops, laser or surgery (or a combination of these). You can usually still wear contact lenses while being treated for glaucoma, and they will not affect the outcome of the disease.
Yes. It is best to remove contact lens when administering glaucoma eye drops. Also contact lens may be more difficult to use after glaucoma trabeculectomy surgery.
