At a glance
Glaucoma treatment by laser or surgery is a set of procedures that lower the pressure inside the eye to stop further damage to the optic nerve (the cable that carries sight signals from the eye to the brain).
In glaucoma, fluid builds up inside the eye and the pressure rises high enough to slowly crush the optic nerve fibres. Laser and surgical treatments either create a new drainage path for that fluid, widen an existing one, or destroy some of the tissue that makes the fluid in the first place. The goal is not to restore lost vision but to prevent more of it from being lost.
Medical Condition
Doctors recommend laser or surgical glaucoma treatment when eye-drop medications alone are no longer keeping the intraocular pressure (pressure inside the eye) at a safe level, or when the optic nerve continues to deteriorate despite drops.
- Open-angle glaucoma (the commonest type, where the drainage angle in the eye is open but drainage is slow) that does not respond well to drops.
- Angle-closure glaucoma, where the drainage angle is blocked and pressure spikes quickly, sometimes as an emergency.
- Normal-tension glaucoma where the nerve keeps deteriorating even though pressure readings appear normal.
- Secondary glaucoma caused by other eye conditions such as uveitis (eye inflammation), diabetes-related eye disease, or previous eye injury.
- Congenital glaucoma in infants and children, where surgery is usually the first-line treatment.
- Patients who cannot use drops reliably because of side effects, cost, or difficulty with the routine.
Laser or surgery is usually not the first choice when glaucoma is newly diagnosed and mild, when eye drops are still controlling pressure well, or when the patient's overall health makes anaesthesia too risky. The decision depends on which type of glaucoma is present, how advanced the damage is, and what the ophthalmologist (eye specialist) finds on examination.
Risks & Complications
All glaucoma laser and surgical procedures carry some risk, though the level varies considerably between a brief laser session and a full surgical operation.
- Temporary rise in eye pressure in the hours immediately after laser treatment, which is usually managed with drops.
- Inflammation (redness, aching) inside the eye, which typically settles within days to weeks.
- Infection inside the eye (endophthalmitis), a rare but serious complication that can threaten sight.
- Bleeding inside the eye during or after surgery.
- Formation of a bleb (a small blister on the surface of the eye) after filtering surgery, which can sometimes become infected or uncomfortable.
- Under-correction, meaning pressure does not fall enough and further treatment is needed.
- Over-correction, meaning pressure drops too low (hypotony), which can blur vision and affect the retina.
- Cataract (clouding of the eye's natural lens) developing or worsening after some types of glaucoma surgery.
- Loss of vision, including in rare cases a worsening rather than stabilising of sight.
Preparation & Procedure
Preparation depends on whether the procedure is a laser session (usually done in an outpatient clinic with no sedation) or a surgical operation (which may require local or general anaesthesia). Your care team will give specific instructions, but the following is what patients typically encounter.
For laser procedures, fasting is usually not required. For surgery under local anaesthesia, the team may ask you to stop eating and drinking for several hours beforehand. If general anaesthesia is planned, fasting guidelines are stricter. Blood thinners and some other medications are often paused before surgery; the ophthalmologist coordinates this with any other doctors managing those conditions.
Smoking and alcohol are generally discouraged in the days before surgery because they can affect healing and anaesthesia. Arrange transport home in advance, as your vision will be temporarily affected and you will not be able to drive.
Tests and assessments run beforehand usually include:
- Tonometry to measure the current eye pressure.
- Visual field testing to map where any peripheral (side) vision has already been lost.
- Optic nerve imaging, often using OCT (optical coherence tomography, a scan that produces detailed cross-section pictures of the nerve).
- Gonioscopy (a lens examination) to look at the drainage angle inside the eye.
- General health checks, including blood pressure, and blood tests if general anaesthesia is planned.
On the day of a laser or surgical procedure, the steps typically follow this order:
- Consent and final check-in: you confirm the planned procedure and sign consent forms.
- Anaesthetic drops or injection: for most laser procedures, drops alone numb the eye surface; for surgery, a local injection numbs the whole eye area, or general anaesthesia is given.
- Eye cleaning and draping: the skin around the eye is cleaned and sterile drapes are placed.
- The laser or surgical step: depending on the procedure chosen, the surgeon creates a new drainage channel (trabeculectomy), places a small drainage tube (tube shunt), applies laser to the drainage angle (laser trabeculoplasty), or performs another indicated technique.
- Pressure check: eye pressure is measured immediately after.
- Patching or shielding: the eye is usually covered with a pad or a protective shield.
- Brief monitoring: you rest in the clinic or ward for a period before being discharged, shorter after laser than after surgery.
Aftercare
Recovery after a laser session is usually measured in days, while recovery after glaucoma surgery is measured in weeks to months. During this time the eye is fragile and needs careful protection.
- Eye drops: antibiotic and anti-inflammatory drops are prescribed after most procedures and must be used exactly as directed for as long as the team specifies, often several weeks.
- Pressure-lowering drops: some patients still need their glaucoma drops after surgery, at least temporarily, until the ophthalmologist confirms the pressure is stable.
- Activity limits: heavy lifting, swimming, and any activity that strains or raises pressure in the head is usually avoided for several weeks after surgery; laser restrictions are shorter.
- Eye protection: a shield is often worn at night to prevent accidental rubbing; sunglasses protect against glare and dust outdoors.
- No rubbing or pressing: the eye must not be touched or rubbed, which could displace a wound or a drainage bleb.
- No eye make-up until the doctor confirms the eye has healed.
- Follow-up visits: these are frequent in the first weeks, typically within the first day, then at one week, one month, and at regular intervals after that; the schedule is tighter after surgery than after laser.
- Visual field and OCT scans: repeat tests over months and years tell the ophthalmologist whether the optic nerve is stable.
- Driving: most patients cannot drive until the doctor clears them, which may take days after laser or weeks after surgery.
- Long-term monitoring: glaucoma is a lifelong condition and even after successful treatment, regular eye pressure checks and nerve assessments continue indefinitely.
Cost & What Determines It
The cost of glaucoma laser or surgical treatment varies widely because the price reflects the type of procedure chosen, the technology available at the facility, the country where it is performed, and the clinical complexity of each patient's case.
- Type and complexity of procedure: a brief laser trabeculoplasty session costs far less than a trabeculectomy (filtering surgery) or tube shunt implantation, which require an operating theatre and longer hospital stays.
- Disease stage: advanced glaucoma with very low target pressures may need combined procedures or repeated sessions, adding to the total.
- Implant or device: tube shunts and minimally invasive glaucoma surgery (MIGS) devices involve the cost of the implant itself, which can be substantial.
- Hospital class and country: a private tertiary eye hospital in a high-income country will price the procedure differently from a specialist eye centre in Southeast Asia.
- Anaesthesia type: local anaesthesia costs less than general anaesthesia, which adds an anaesthetist fee and monitoring equipment.
- Length of stay: laser procedures are almost always outpatient; surgical procedures may require one or more nights in the ward.
- Medications: post-operative eye drops and any systemic medications needed during recovery are usually billed separately.
- Pre- and post-operative tests: OCT scans, visual field tests, and other assessments before and after the procedure are typically added to the bill individually.
A hospital package for glaucoma surgery often covers the surgeon's fee, theatre costs, the implant if one is used, nursing care during the hospital stay, and a set number of post-operative visits. Items that tend to be billed separately include additional follow-up visits beyond the package limit, extra diagnostic scans, prescription eye drops, and treatment of any complications.
BPJS Kesehatan and most Indonesian private health insurance plans do not cover treatment received abroad, so patients travelling overseas for glaucoma surgery typically pay out of pocket or through an international private insurance policy that explicitly includes overseas care. Before booking travel, ask the hospital for a written cost estimate that lists what is and is not included. This protects you from unexpected charges once you arrive, particularly for high-cost items like tube shunt devices or extended post-operative monitoring.
Frequently Asked Questions
How many sessions of glaucoma laser or surgery will I need?
Most patients need only one session, though some laser types may be repeated if eye pressure does not come down enough. Your doctor will decide based on how advanced your glaucoma is, which treatment you are having, and how your eye responds over the following weeks.
What does glaucoma laser or surgery feel like?
Laser treatment is usually done with numbing eye drops and feels like brief flashes of light with little or no discomfort. Surgery involves a local anaesthetic (medicine that blocks feeling in the eye area) so most people feel pressure rather than pain during the procedure, and any soreness afterward is usually manageable with standard pain relief.
How soon will I know if the treatment is working?
Eye pressure is usually checked at your first follow-up visit, often within a few days to a week after the procedure. However, the full effect on slowing vision loss can take weeks to months to assess, so regular check-ups are a key part of your care.
How much does glaucoma laser or surgery cost?
The cost depends on several factors specific to your case, including whether you are having laser treatment or a surgical procedure, the type of implant or drainage device used if surgery is chosen, and the class of hospital and length of aftercare needed. A written estimate from the hospital, based on your consultation and diagnosis, is the most accurate way to know what to budget for.
