Introduction

Glaucoma refers to a group of eye diseases that cause increased pressure inside the eye, potentially leading to damage of the optic nerve. This nerve is essential for transmitting visual information from the eye to the brain, and if left untreated, glaucoma can cause significant vision loss or even blindness. Often developing gradually without obvious symptoms, glaucoma is sometimes referred to as a “silent thief of sight,” underscoring the importance of regular eye exams, particularly for those at higher risk.

When glaucoma cannot be managed with medications or laser treatments, surgery becomes a key option for lowering eye pressure and preventing further damage. Glaucoma surgery is designed to enhance fluid drainage in the eye, reducing intraocular pressure. At SNU Eye Clinic, we provide a variety of surgical options, each customized to fit the individual needs of our patients. With a history of over 50,000 successful surgeries, our clinic is known for its advanced care and commitment to long-term patient outcomes.

Exploring Types of Glaucoma Surgery

Different types of glaucoma surgery are recommended based on the stage of the disease, the type of glaucoma, and the patient's overall eye health. Here are the most common options:

1. Trabeculectomy: Often considered the traditional approach, trabeculectomy involves creating a small drainage hole in the eye to allow excess fluid to escape and lower eye pressure. This surgery is commonly used for more advanced glaucoma cases, though it requires careful post-operative monitoring.

2. Drainage Implants: In cases where trabeculectomy is insufficient, drainage implants (tube shunts) are used. These small tubes are surgically inserted into the eye to assist with fluid drainage and maintain eye pressure. This method is typically employed in more complicated or advanced glaucoma.

3. Laser Glaucoma Surgery: Laser procedures such as Selective Laser Trabeculoplasty (SLT) and Laser Peripheral Iridotomy (LPI) provide less invasive treatment options. SLT uses laser energy to open up blocked drainage channels, while LPI creates small holes in the iris to help reduce pressure. These options are generally considered for early-stage glaucoma or for patients not suited for more invasive surgery.

4. Minimally Invasive Glaucoma Surgery (MIGS): MIGS techniques involve smaller incisions and less disruption to the eye, allowing for faster recovery and less pain. Procedures like the iStent or Hydrus Microstent are designed to treat mild to moderate glaucoma. MIGS procedures are popular due to their ability to deliver effective results with fewer risks and quicker recovery times.

At SNU Eye Clinic, we are proud to offer these advanced surgical options, ensuring that our patients receive the best possible care with minimal discomfort and faster recovery.

Is Glaucoma Surgery Painful?

Many patients wonder if glaucoma surgery will be painful. Thankfully, modern surgical techniques, particularly minimally invasive procedures, are designed to minimize discomfort. Local anesthesia is administered to numb the area around the eye, ensuring that most patients experience little to no pain during the procedure itself. Some may feel mild pressure or a slight discomfort, but these sensations are usually brief and quickly subside. For those who are anxious, a mild sedative may also be provided to help them relax.

After surgery, patients may experience some soreness, especially if more invasive procedures like trabeculectomy are performed. However, any pain is typically manageable with prescribed medications, and most patients notice significant relief within a few days.

What to Expect During Glaucoma Surgery?

Glaucoma surgeries are usually performed on an outpatient basis, meaning patients can return home the same day. Here's a step-by-step guide to what you can expect before, during, and after the procedure:

1. Pre-Surgery Preparation: Your surgeon will thoroughly clean the area around your eye, and local anesthesia will be applied via eye drops or, in some cases, an injection. If you feel anxious, a mild sedative will help you relax.

2. Surgical Procedure: The exact surgery will depend on the type of procedure you're undergoing. For trabeculectomy, a small incision is made to create a drainage channel in the eye. In laser surgery, a laser is used to open blocked drainage pathways or to make small holes in the eye. For MIGS procedures, small incisions are made to implant devices that help with fluid drainage.

3. Post-Surgery Care: After surgery, you will be monitored for a short period to ensure everything is progressing as expected. It’s common to experience blurry vision and mild discomfort in the hours following surgery. However, these symptoms typically subside within a few hours to days. You may be prescribed antibiotics or anti-inflammatory eye drops to reduce infection and swelling.

At SNU Eye Clinic, we focus on precision during surgery, ensuring your comfort and safety throughout the process.

Pain Management During Glaucoma Surgery

While pain during the surgery is minimal thanks to local anesthesia, some patients might feel mild pressure or discomfort. After surgery, any pain is typically very manageable. For more invasive surgeries like trabeculectomy, there may be some discomfort, but it is usually short-lived and can be controlled with pain medications.

Post-Surgery Recovery: What to Expect

After surgery, some patients may experience mild discomfort, blurred vision, or sensitivity to light. These are normal symptoms and should resolve within a few hours to days. However, following your surgeon’s post-operative instructions is essential for a smooth recovery.

To manage recovery, patients are often prescribed eye drops to prevent infection and inflammation. Regular follow-up appointments will ensure that your eye is healing well and that the surgery has successfully reduced intraocular pressure.

Pain After Glaucoma Surgery: How Long Does It Last?

In the days following glaucoma surgery, mild soreness or discomfort is common. The majority of patients notice improvement within the first few days, and any pain usually disappears within 2-4 weeks. For minimally invasive surgeries, recovery tends to be quicker, with less pain overall. If you experience persistent pain, vision changes, or redness, be sure to contact your doctor right away.

Recovery Timeline for Glaucoma Surgery

Recovery varies depending on the type of surgery. Here’s a general timeline:

• First Week: Rest and avoid strenuous activities. You may experience blurred vision and mild discomfort.

• First Month: Vision should begin to stabilize, and most patients can resume normal activities, including work.

• 3 to 6 Months: Full recovery can take several months, and regular eye pressure monitoring will be required to ensure success.

At SNU Eye Clinic, our team of ophthalmologists ensures that your recovery is closely monitored every step of the way.

Potential Risks and Side Effects

As with any surgery, there are risks, although serious complications are rare. Possible side effects include:

• Mild Discomfort: Some soreness, irritation, or pressure may be felt after surgery.

• Infection: Infection is uncommon but can occur, so your doctor will prescribe medications to help prevent it.

• Increased or Decreased Eye Pressure: Sometimes eye pressure may be too high or too low after surgery, requiring additional treatment.

• Vision Changes: Temporary blurry or fluctuating vision is common in the initial stages of recovery.

• Inflammation: Mild swelling or redness may occur but should resolve over time.

At SNU Eye Clinic, we take every precaution to minimize these risks and monitor your progress carefully.

Managing Pain During Recovery

After surgery, pain can generally be controlled with:

• Medications: Over-the-counter pain relievers or prescribed medication can help manage discomfort.

• Cold Compresses: Applying a cold compress to the eye can reduce swelling and soothe discomfort.

• Eye Drops: Prescription drops can help reduce inflammation and prevent infection.

• Rest: Avoid physical strain and follow your doctor's advice to ensure proper healing.
