Glaucoma

Preparing for Surgery & What to Expect

Preoperative Steps

1. A complete eye exam, imaging, and diagnostic testing to assess optic nerve, drainage angle, and ocular anatomy.
2. Review your full medical history, including systemic diseases (e.g. diabetes, hypertension), medications (especially blood thinners), and lifestyle factors.
3. You may need to stop certain medications (NSAIDs, aspirin, anticoagulants) before surgery to reduce bleeding risk.
4. Arrange for a driver post-surgery, as sedatives or anesthesia may impair your ability to drive.
5. You may need to fast (no food or drink) for several hours prior to surgery, depending on anesthesia.

During Surgery

1. Laser treatments are often done in the physician’s office under topical anesthesia.
2. Incisional, MIGS, and tube shunt surgeries typically occur in an operating room, under local anesthesia, sedation, or sometimes general anesthesia.
3. The surgery duration depends on the procedure type: many laser procedures take minutes, whereas incisional surgeries may take up to an hour.

Postoperative Care and Recovery

1. After surgery, you’ll likely receive eye drops (antibiotic, steroid, IOP-lowering) to prevent infection, inflammation, and manage pressure.
2. Eye patching or shield use may be necessary temporarily.
3. Limit certain activities for weeks: avoid heavy lifting, straining, bending over, or vigorous exercise.
4. Avoid rubbing your eye, swimming, or environments that could expose your eye to water or contaminants until cleared by your surgeon.
5. Frequent follow-up appointments are critical to monitor IOP, healing, and any complications.

Recovery Timelines Vary

1. For less invasive (laser or MIGS) procedures, many patients resume normal activities within days.
2. For incisional and shunt surgeries, recovery may require weeks to a month of careful management.

You should contact your surgeon immediately if you experience sudden worsening pain, loss of vision, excessive redness or discharge, or other concerning symptoms.

Risks and Benefits of Glaucoma Surgery

Benefits

1. Can slow or halt further optic nerve damage by achieving lower, more stable IOP.
2. Can reduce dependence on medications and their side effects.
3. In some cases, more sustainable long-term IOP control than lasers or drops alone.

Risks & Potential Complications

As with any surgery, there are risks. Some include:

1. Hypotony (too low eye pressure), which can damage structures of the eye
2. Scarring or closure of the surgically created drainage pathways, which may reduce effectiveness over time
3. Bleeding or hemorrhage inside the eye
4. Infection or endophthalmitis (rare but serious)
5. Damage to cornea or other eye structures
6. Vision loss or worsening visual field (though the surgery’s goal is to prevent further loss)
7. Need for additional surgeries if the initial surgery fails or effects wane over time

Because Arizona’s dry climate may affect ocular surface health and healing, surgeons and patients in the state often take special care with postoperative eye hydration and protection against surface drying.

Special Considerations for Arizona Patients

While the fundamental science of glaucoma surgery is universal, living in Arizona adds a few specific angles to consider:

Dry Climate & Ocular Surface Health

Arizona’s arid conditions may worsen dry eye symptoms, which can affect healing and patient comfort after surgery. Surgeons may prescribe frequent lubricating drops or punctal plugs to mitigate surface dryness.

UV Exposure & Outdoor Lifestyle

Many Arizonans spend significant time outdoors. After surgery, you’ll need to protect the eye from sun, dust, and wind by using wraparound sunglasses, hats, and avoiding direct exposure during early healing phases.

Access to Retina & Glaucoma Specialists

In urban areas (Phoenix, Tucson), advanced glaucoma and surgical care are accessible. In rural parts of Arizona, travel to specialty centers may be necessary. Patients should plan for follow-up travel and coordination.

Prevalence of Comorbidities

Arizona has a large aging population, and conditions like diabetes, hypertension, and cardiovascular disease are common. These systemic diseases may affect surgical planning, healing, and risk stratification.

Water & Sterility during Recovery

Given the importance of avoiding contamination while eyes heal, desert dust and hard water could pose increased risk during cleaning or washing. Following strict instructions for eye care hygiene is vital.
