The goal of all glaucoma treatment is to lower intraocular pressure to a level that prevents further damage to the optic nerve. While eye drops are the most common starting point, they don’t work for everyone. SLT (selective laser trabeculoplasty) is also an established first line treatment which allows patients to remain drop-free in some instances. Glaucoma surgery encompasses a range of laser and surgical procedures designed to improve fluid drainage and reduce pressure.
At Pure Sight Eye Surgeons, our team offers several glaucoma treatment options, from in-clinic laser procedures to surgical interventions performed in combination with cataract surgery.
Selective Laser Trabeculoplasty (SLT)
SLT is a laser treatment that stimulates the trabecular meshwork to improve its ability to drain fluid, lowering eye pressure. It’s increasingly used as a first-line treatment for open-angle glaucoma.
- Performed in the clinic, not in an operating theatre
- Takes only a few minutes
- Uses a low-energy laser that doesn’t cause thermal damage
- Can be repeated if the effect diminishes over time
- May reduce or eliminate the need for daily eye drops
Laser Iridotomy
Laser iridotomy is used to treat or prevent angle-closure glaucoma. A laser creates a small opening in the iris, allowing fluid to flow more freely to the drainage angle. This is performed in our clinic rooms by all surgeons at Pure Sight and is a quick procedure with topical anaesthesia.
Minimally Invasive Glaucoma Surgery (MIGS)
MIGS refers to newer surgical procedures using microscopic devices to improve fluid outflow. Devices include the iStent, Hydrus Microstent, and Xen Gel Stent, among others. All surgeons at Pure Sight perform MIGS, with the specific device selected based on the type and stage of glaucoma.
MIGS procedures are often performed at the same time as cataract surgery, allowing patients to address both conditions in a single procedure. They provide meaningful pressure reduction with less risk and faster recovery than traditional glaucoma surg
Traditional Glaucoma Surgery
For patients with more advanced or difficult-to-control glaucoma where drops, laser, and MIGS are insufficient, more extensive surgical options may be considered. These include trabeculectomy (creating a new drainage pathway) and tube shunt surgery (implanting a small tube to redirect fluid). These procedures are typically managed by a glaucoma subspecialist.
Laser Cyclophotocoagulation
In cases where other treatments have been exhausted, laser can be applied to the ciliary body to reduce fluid production. Typically reserved for advanced glaucoma.
Frequently Asked Questions
Can glaucoma surgery restore lost vision?
No. Surgery aims to lower eye pressure and prevent further damage. Vision already lost to glaucoma can’t be recovered, which is why early detection is critical.
Will I still need eye drops after glaucoma surgery?
It depends on the procedure and how well it controls your pressure. SLT and MIGS may reduce or eliminate the need for drops. Your doctor will adjust medication based on post-operative results.
