This type of laser surgery is usually reserved for eyes that either have elevated IOP after having failed other more traditional treatments, or those in which filtering surgery is not possible or advisable due to specific features of the eye.

Traditional Surgery

When medications and laser therapies do not adequately lower eye pressure, doctors may recommend conventional surgery.


This common surgery is used in both open-angle and closed-angle glaucomas. It is usually an outpatient procedure. The number of post-operative visits to the doctor varies, and some activities, such as driving, reading, bending and heavy lifting must be limited for a period of time after the surgery. Even after having a trabeculectomy, a glaucoma patient may still need to use some eye drops to keep their pressure in the desired range.
