What Is Glaucoma & Why Surgery May Be Needed
Glaucoma is a group of eye diseases that damage the optic nerve, very often due to elevated intraocular (eye) pressure. Over time, glaucoma can cause irreversible vision loss.
When medications or laser treatments fail to control pressure, glaucoma surgery becomes necessary to preserve remaining vision and prevent further damage.
Types of Glaucoma Surgery
At Vasan Eye Care, we offer multiple surgical options based on the type and stage of glaucoma:
| Surgical Method | Description |
|---|---|
| Trabeculectomy | Creates a new drainage pathway for aqueous fluid to exit the eye and lower intraocular pressure. |
| Tube Shunt / Glaucoma Drainage Devices | A small tube and plate system implanted to divert fluid and reduce pressure. |
| Minimally Invasive Glaucoma Surgery (MIGS) | Less invasive procedures with quicker recovery (e.g. iStent, Kahook Dual Blade). |
| Laser-Assisted Glaucoma Procedures | Such as SLT (Selective Laser Trabeculoplasty) or laser goniotomy to improve drainage. |
What to Expect During the Procedure
- Preoperative Assessment
Thorough eye measurements, optic nerve imaging, and pressure mapping. - Anesthesia
Local anesthesia is used to numb the eye; sedation may be offered. - Surgery
Depending on the technique, the surgeon creates a controlled opening or implants a device to help fluid flow out. - Closure & Recovery
Tiny sutures or self-sealing incisions, followed by protective eye patch or shield.
Risks & Considerations
While glaucoma surgery is generally safe, possible complications may include:
- Bleeding
- Low eye pressure (hypotony)
- Infection
- Scar formation blocking the new drainage
- Need for additional surgery
Both Mayo Clinic and Cleveland Clinic outline these risks and emphasize close monitoring post-surgery.
Recovery & Follow-Up Care
- Vision may be blurry for days to weeks
- Use of eye drops and medications will be strict
- Avoid heavy lifting, bending forward, or strenuous activity
- Regular follow-up visits to check IOP (intraocular pressure) and surgery success
Most patients return to normal routines within a few days, though full stability may take some weeks.
Glaucoma Surgery Cost
The cost of glaucoma surgery varies based on:
- The surgical method (trabeculectomy, MIGS, implants)
- Surgeon expertise
- Hospital facility and post-op care
- Geographic location
At Vasan Eye Care, we aim to provide transparent pricing and support with insurance or EMI options wherever possible.
