Ab Interno Trabeculectomy (e.g.; Trabectome; Kahook Dual Blade) in Hyderabad: Cost, Procedure & Recovery

Ab Interno Trabeculectomy is a modern, minimally invasive eye surgery designed to treat glaucoma by improving the natural drainage system of your eye. This procedure helps lower eye pressure, which is crucial for preventing vision loss caused by glaucoma, offering a gentle approach to managing this condition.

QUICK FACTS

  • Procedure Duration: 15-30 minutes
  • Anesthesia Type: Topical numbing eye drops / Local
  • Recovery Time: 24-48 hours
  • Hospital Stay: Daycare / No overnight admission required

UNDERSTANDING THE BASICS

What is Ab Interno Trabeculectomy (e.g.; Trabectome; Kahook Dual Blade)?

Imagine your eye has a tiny drain system that constantly removes fluid, much like a sink. In glaucoma, this drain, called the trabecular meshwork, can become clogged or not work efficiently, causing fluid to build up and eye pressure to rise. Ab Interno Trabeculectomy is a specialized surgery that uses a tiny instrument, like the Trabectome or Kahook Dual Blade, to gently open or remove a small part of this clogged drainage system from inside the eye. This helps the fluid flow out more freely, reducing the pressure and protecting your vision. This falls under the category of Minimally Invasive Glaucoma Surgery (MIGS) & Non-Penetrating Surgery, a sub-category of Glaucoma Surgical & Laser Interventions.

CONDITIONS AND SYMPTOMS

Why is Ab Interno Trabeculectomy (e.g.; Trabectome; Kahook Dual Blade) performed?

Eye Conditions Treated

  • Primary Open-Angle Glaucoma (when eye drops are not enough or cause side effects)
  • Ocular Hypertension (high eye pressure without optic nerve damage, but with high risk)
  • Certain types of secondary glaucoma (glaucoma caused by another eye condition)

Symptoms You Might Be Experiencing

Often, early glaucoma has no noticeable symptoms. However, if your eye pressure remains high despite medication, or if your doctor observes damage to your optic nerve, this procedure may be recommended to prevent further vision loss. You might not feel specific symptoms, but your doctor will monitor:

  • Consistently high eye pressure readings
  • Changes in your optic nerve detected during eye exams
  • Progressive loss of peripheral (side) vision, often unnoticed until advanced stages

SURGICAL JOURNEY STEP-BY-STEP

How is the Ab Interno Trabeculectomy (e.g.; Trabectome; Kahook Dual Blade) Procedure Performed?

1. How to Prepare Before the Procedure

  • Medical Evaluation: Your ophthalmologist will conduct thorough eye exams, including measuring eye pressure, checking your optic nerve, and possibly visual field tests.
  • Medication Review: Discuss all medications you are taking with your doctor. You may be asked to stop certain blood thinners for a few days before surgery.
  • Fasting: You might be asked to fast (no food or drink) for several hours before the procedure, especially if light sedation is used.
  • Arrange Transport: You will not be able to drive yourself home after the surgery, so arrange for someone to pick you up.
  • Avoid Eye Makeup: Do not wear eye makeup on the day of your surgery.

2. What Happens During the Procedure?

The Ab Interno Trabeculectomy is typically an outpatient procedure.

  • Anesthesia: Numbing eye drops or a local anesthetic injection will be used to ensure you feel no pain during the surgery. You might also receive a mild sedative to help you relax.
  • Preparation: Your eye area will be cleaned, and a sterile drape will be placed around your eye. An eyelid holder will gently keep your eye open.
  • The Procedure: Using a high-magnification microscope, your surgeon will make a tiny, self-sealing incision in your cornea (the clear front part of your eye). A specialized micro-instrument, such as the Trabectome or Kahook Dual Blade, is then carefully inserted into the eye’s drainage angle. This instrument precisely removes or modifies a small section of the trabecular meshwork, allowing fluid to drain more effectively.
  • Completion: The instrument is withdrawn, and the tiny incision usually closes on its own without stitches.

3. What to Expect Immediately After the Procedure

  • Recovery Lounge: After the procedure, you will rest in a recovery area for a short period while the anesthesia wears off.
  • Eye Protection: A protective eye shield or patch will be placed over your treated eye to prevent accidental rubbing or injury.
  • Vision: Your vision in the treated eye will likely be blurry immediately after surgery due to the procedure and dilating drops.
  • Discomfort: You might experience mild discomfort, a gritty sensation, or sensitivity to light. Your doctor may prescribe pain relievers if needed.
  • Discharge: Once your doctor determines you are ready, you will be discharged with detailed instructions for post-operative care and a schedule for follow-up appointments.

POST-OPERATIVE CARE AND TIMELINE

Recovery and Post-Operative Care

Following your doctor’s instructions carefully is vital for a smooth recovery and successful outcome.

  • Do’s:
  • Use all prescribed eye drops exactly as directed to prevent infection and control inflammation.
  • Wear your protective eye shield, especially while sleeping, for the recommended period.
  • Attend all scheduled follow-up appointments with your ophthalmologist.
  • Gently clean around your eye with a clean, damp cloth if needed.
  • Don’ts:
  • Do not rub or press on your treated eye.
  • Avoid strenuous activities, heavy lifting, bending over, or swimming for at least a few weeks.
  • Do not wear eye makeup for the first few weeks.
  • Avoid getting water directly into your eye while showering or washing your hair.
  • Do not drive until your vision has stabilized and your doctor approves.

Recovery Timeline:

  • Day 1: You will have your first follow-up appointment. Expect some blurry vision, mild discomfort, and possibly a feeling of grittiness. Your doctor will check your eye pressure and overall healing.
  • Week 1: Your vision should gradually start to clear, though it may still fluctuate. Continue using your eye drops. Most mild discomfort should subside. You can typically resume light, non-strenuous activities.
  • Month 1: Most of the initial healing is complete. Your eye pressure should be more stable, and your vision will have significantly improved. Your doctor will continue to monitor your progress and adjust eye drop regimens as needed. You can usually return to most normal activities, but always confirm with your ophthalmologist.
