What is glaucoma surgery?

Medcasts editorial team

Glaucoma surgery aims to lower intraocular pressure when medications and laser are insufficient. Options include:

• Trabeculectomy: traditional gold-standard, creates a new drainage channel. • Tube shunt (Ahmed, Baerveldt): drainage device for refractory cases. • MIGS (minimally invasive glaucoma surgery): newer techniques like iStent, Hydrus, Xen — less invasive but lower IOP-lowering effect.

Decision points: severity of glaucoma, prior treatments, anatomy, patient preference. MIGS is often combined with cataract surgery for mild-moderate glaucoma; trabeculectomy or tube shunts for severe disease.

Recovery: most glaucoma surgery is outpatient. Vision may be temporarily affected. Long-term IOP control is the metric, not immediate vision.

For international travel, glaucoma surgery is feasible at established eye programs. Confirm follow-up imaging and pressure checks transfer back to home ophthalmologist.

Methodology and editorial standards

Answers are written by the Medcasts editorial team and updated when prices, guidelines or visa rules change.

  1. Hospital data. Hospital details are compiled from public sources and hospital websites. Accreditation (JCI, NABH and others) is shown where we hold a record of it. Always ask the hospital for its current certificate.
  2. Doctor credentials. Qualifications, specialty and bio come from the doctor's hospital profile. Licence is checked against the national medical-council register only where the profile shows a "Licence verified" badge with a date.
  3. Prices. Price ranges are indicative, compiled from hospital price lists and packages and shown with the date last updated. The hospital's written quote is what you pay against.
  4. Clinical text. Written by the Medcasts editorial team from published clinical sources. Unless a named reviewer is shown on the page, it has not been reviewed by a doctor.
  5. Independence. Hospitals cannot pay to change their position on our pages.
