Filtration Surgery for Glaucoma: Exploring Trabeculectomy, MicroShunt, and Tube Implants
Filtration surgery is a crucial treatment option for managing glaucoma when other methods prove insufficient. This article explores three primary types of filtration surgery: trabeculectomy, PRESERFLO™ MicroShunt, and tube implants.
Book a ConsultationWhat is FILTRATION SURGERY?
Filtration surgery is a surgical procedure designed to lower intraocular pressure (IOP) in patients with glaucoma.
It is typically recommended when other treatments, such as eye drops or laser therapy, have proven insufficient in managing the condition.
The primary goal of filtration surgery is to reduce IOP by improving the outflow of aqueous humour. Creating an alternative drainage pathway helps relieve pressure on the optic nerve, potentially slowing or halting the progression of glaucoma.
Types of filtration surgery
Discover the different types of filtration surgery offered at OCL Vision
Trabeculectomy
Trabeculectomy is a traditional and widely used surgical technique for glaucoma management. During a trabeculectomy, the surgeon creates a small flap in the sclera (white part of the eye) and removes a portion of the trabecular meshwork. This allows aqueous humour to drain from the anterior chamber into a bleb, reducing IOP.
PRESERFLO™ MicroShunt
The PRESERFLO™ MicroShunt is a minimally invasive glaucoma surgery (MIGS) device designed for patients with primary open-angle glaucoma. The MicroShunt is a small, flexible tube made of a biocompatible material. It creates a drainage pathway for aqueous humour from the anterior chamber to a subconjunctival bleb.
Tube Implants (Glaucoma Drainage Devices)
Tube implants, also known as glaucoma drainage devices, are used to manage complex or refractory glaucoma cases. There are different types of implants, such as the Baerveldt Glaucoma Implant or the Paul Glaucoma Implant. A small silicone tube is inserted into the anterior chamber, connected to a plate positioned under the conjunctiva. This allows aqueous humour to drain, reducing IOP.

- Effective IOP Reduction: Filtration surgery can significantly lower intraocular pressure, often more dramatically than medications or laser treatments.
- Long-term Pressure Control: Many patients experience sustained IOP reduction following the procedure, providing long-term management of their glaucoma.
- Reduced Medication Dependence: A significant number of patients can reduce or eliminate their need for glaucoma medications after surgery, improving quality of life and reducing side effects.
- Vision Preservation: By lowering IOP, filtration surgery helps prevent further damage to the optic nerve and preserves remaining vision.
- High Success Rate: Long-term studies show that trabeculectomy, a common type of filtration surgery, has a high success rate. It's estimated that 90% of surgeries are successful, with two-thirds of individuals no longer needing medication to control the condition afterwards.

Before Your Consultation
Get Ready for Your OCL Vision Consultation
To help you feel comfortable and make the most of your visit, we’ve outlined a few simple steps to prepare for your consultation at OCL Vision. Please take a moment to review them before your appointment.

3. Access Your Patient Portal
You will receive secure login details to access your personal OCL Vision patient portal. Here, you can view appointment times, payment balances and important updates.

You will have time to ask questions and receive expert advice tailored to your individual case.

Filtration Surgery FAQ's
View knowledge baseHow long does recovery take after filtration surgery?
Recovery times vary depending on the procedure. Trabeculectomy typically requires 4-6 weeks, while MIGS procedures like the PRESERFLO™ MicroShunt may have shorter recovery periods of 2-3 weeks.
Will I still need glaucoma medications after surgery?
Many patients experience reduced dependence on glaucoma medications after surgery. However, some may still require medication to maintain optimal IOP control.
Which filtration surgery is best for me?
The most suitable procedure depends on various factors, including the type and severity of your glaucoma, previous treatments, and overall eye health. Your ophthalmologist will recommend the best option based on your individual case.
Can filtration surgery cure glaucoma?
While filtration surgery can effectively manage IOP and slow disease progression, it cannot cure glaucoma or restore vision already lost. The goal is to preserve remaining vision and prevent further damage.
Are scans included in the glaucoma consultation price?
Scans are not included in the initial consultation fee. The initial consultation is £270, and scans cost £310 in total (either 1 or 2 scans, as confirmed by the consultant). This brings the total price to £580.
