In angle closure glaucoma, the laser creates a hole in the iris (Iridotomy) to improve the flow of aqueous fluid to the anterior chamber of the eye.

When surgery in the operating theatre is needed to treat glaucoma, your ophthalmologist uses fine, microsurgical instruments to create a new drainage channel for the aqueous fluid to leave the eye. This procedure is known as a trabeculectomy. Surgery is generally recommended if your ophthalmologist feels it is necessary to prevent further damage to the optic nerve.

This glaucoma surgery may also be performed in conjunction with a cataract procedure, if you require cataract surgery. Please see cataract details in this section.

Patients are admitted to the day surgery one and a half hours prior to surgery for preoperative eye-drops. The expected length of stay is 3 to 4 hours from admission.
