Trabeculectomy for Treating Glaucoma

Trabeculectomy is a surgical procedure designed to relieve intraocular pressure in patients with glaucoma, particularly when other treatments have failed to achieve adequate control. This surgical approach can be crucial in preserving visual function by managing the progression of glaucoma. If you’d like to learn more about this treatment option, here’s an overview.  

What Is Trabeculectomy?

Trabeculectomy, often called filtering surgery, involves creating a new drainage pathway for the aqueous humor, the fluid inside the eye. This procedure targets the trabecular meshwork—where fluid drainage from the eye naturally occurs but is typically impeded in patients with glaucoma.  

During the surgery, the ophthalmologist removes a small piece of tissue from the eye’s drainage angle, creating an opening. This opening is covered with a flap of scleral tissue, the white part of the eye, and partially stitched closed to allow fluid to escape at a controlled rate. The fluid then collects in a reservoir called a bleb, usually concealed under the upper eyelid, from where it is absorbed into the bloodstream.  

Indications for Trabeculectomy

Trabeculectomy is generally recommended for patients whose glaucoma cannot be controlled with eye drops, pills, or laser treatments. It is particularly beneficial in cases of open-angle glaucoma, the most common form of the condition. This surgery may also be considered in patients with closed-angle glaucoma or in individuals who have developed glaucoma despite clear drainage angles, known as normal-tension glaucoma.  

Benefits of Trabeculectomy

The primary benefit of trabeculectomy is its ability to reduce intraocular pressure significantly when less invasive treatments are insufficient. By lowering the pressure, trabeculectomy helps to prevent further optic nerve damage and subsequent loss of vision. Many patients who undergo this procedure achieve stable eye pressure, which can reduce or sometimes eliminate the need for glaucoma medications.  

Risks and Complications

As with any surgical procedure, trabeculectomy carries potential risks and complications. Common concerns include infection, bleeding, and an over- or under-filtration of aqueous humor. In some cases, the newly created drainage channel may scar and close, reducing the effectiveness of the surgery. Long-term complications can include cataract formation and vision changes.  

Postoperative Care and Follow-up

After trabeculectomy, close follow-up care with an ophthalmologist is critical to monitor the eye’s healing process and adjust treatment as necessary. Patients typically receive medications to prevent infection and manage inflammation. Regular check-ups are essential to ensure that the drainage channel remains open and functions correctly and to assess the intraocular pressure.  

The immediate postoperative period may involve wearing an eye patch and avoiding strenuous activities or anything that could stress the eyes, such as bending or heavy lifting. Recovery time varies, but most patients can return to their normal activities within a few weeks with continued monitoring.

Common Questions About Cataract Surgery Answered by Buffalo, NY Ophthalmologists

More than 6.1 million American cataract patients have successfully undergone surgery to remove them. This statistic marks the surgery as one of the more common in the medical world. If you live past 70, the chances are high you’ll experience cataracts in one or both of your eyes. But what are cataracts, and should you worry about your vision?

Cataracts are a common eye condition characterized by the clouding of the lens, which leads to a decrease in vision or, if left untreated, blindness. They are primarily associated with aging but can also result from various other factors such as eye injury.

Cataracts are one of the leading causes of blindness worldwide, making it essential to seek timely and expert medical guidance. Despite surgical advancements, however, many countries lack access to these procedures. As a result, a significant number of people each year outside the U.S. go blind from cataracts.

In Buffalo, NY, the presence of skilled ophthalmologists ensures that cataract patients receive the best care to manage their condition, including surgery to enhance their quality of life through improved vision.

What Are Cataracts?

Cataracts occur when proteins in the eye’s lens clump together, forming cloudy areas that impair vision. This condition can develop in one or both eyes but does not spread from one eye to the other. While aging is the most significant risk factor for cataracts, other factors include diabetes, smoking, prolonged exposure to ultraviolet sunlight, and certain medications. Given the prevalence of these risk factors, residents of Buffalo, NY, particularly the aging population, should be aware of cataracts and consider regular eye check-ups to detect and manage this condition early.

Understanding the Eye Anatomy

The eye is a complex organ composed of several parts working together to process visual information. Key structures include the cornea, lens, retina, optic nerve, and vitreous humor. The lens, located behind the iris, focuses light onto the retina. Cataracts affect the lens by causing it to become cloudy, scattering light, and preventing a clear image from forming on the retina. This results in blurred vision, glare, and difficulty seeing in low light, significantly impacting daily activities.

Signs and Symptoms of Cataracts


Common symptoms of cataracts include blurred vision, faded colors, glare or halos around lights, difficulty with night vision, and frequent changes in eyeglass prescriptions. If these symptoms interfere with daily activities such as reading, driving, or recognizing faces, it’s crucial to consult an ophthalmologist in Buffalo, NY. Early diagnosis and treatment can prevent further deterioration and help maintain good vision.

Frequently Asked Questions About Cataract Surgery


As a Buffalo, NY, ophthalmology practice, the Eye Care & Vision Associate (ECVA) team has countless positive experiences with successfully helping cataract patients treat their condition. Some of the most frequently asked questions include the following.

  1. What is cataract surgery?
    Cataract surgery involves removing the cloudy lens and replacing it with an artificial intraocular lens (IOL) to restore clear vision. It is a common and generally safe procedure performed by ophthalmologists.
  2. Is cataract surgery painful?
    Cataract patients do not typically experience much discomfort during the procedure. Local anesthesia is used to numb the eye, and patients may feel slight pressure but no pain.
  3. How long does the surgery take?
    The surgery usually takes about 15 to 20 minutes per eye, although patients should expect to spend a few hours at the surgical center for preparation and post-operative care.
  4. What are the risks associated with cataract surgery?
    While cataract surgery is generally safe, like any surgical procedure, it carries risks such as infection, bleeding, inflammation, and retinal detachment. However, these complications are rare.
  5. How soon will I see results after cataract surgery?
    Many patients notice improved vision within a few days after surgery, but it can take a few weeks for the eye to heal fully and for vision to stabilize.
  6. Can cataracts come back after surgery?
    Cataracts do not return after the lens is removed. However, some patients may experience a condition called posterior capsule opacification (PCO), which can cause vision to become cloudy again. Your Buffalo, NY eye surgeon can treat this condition with a quick laser procedure.

The Cataract Surgery Procedure from a Buffalo, NY Ophthalmologist


What’s it like to have cataract surgery? How can patients expect to heal, and what should they expect? There are six typical steps when undergoing a cataract surgery.

Step 1: Pre-operative Assessment
Before surgery, your doctor will conduct a thorough eye examination to assess the overall health of the eyes and determine the appropriate intraocular lens (IOL). Eye measurements are taken to ensure selection of the correct lens.

Step 2: Anesthesia
The doctor will administer local anesthesia to numb the eye; sometimes a mild sedative is given to help the patient relax.

Step 3: Incision
The surgeon will make a small incision in the cornea. Modern techniques use a self-sealing incision that usually does not require stitches.

Step 4: Phacoemulsification
An ultrasound probe is inserted through the incision to break up the cloudy lens into small pieces, then gently suctioned out.

Step 5: Intraocular Lens Implantation
Once the surgeon removes the cataract, a clear intraocular lens (IOL) is inserted into the lens capsule. The IOL is positioned to restore focusing power to the eye.

Step 6: Post-operative Care
After lens implantation, the surgeon will ensure the incision is secure. The cataract patient is then moved to a recovery area for monitoring before discharge from the office with post-operative care instructions.

Recovery and Post-Operative Care


What can cataract patients expect after their surgery? Your Buffalo, NY eye experts have some tips for a successful recovery.

Immediate Post-Operative Period
Patients may experience mild discomfort, itching, and sensitivity to light. It’s important to avoid rubbing the eye and to use prescribed eye drops to prevent infection and reduce inflammation.

Follow-Up Appointments
Regular follow-up visits with the ophthalmologist are crucial to monitor the healing process and address any concerns.

Activity Restrictions
Avoid strenuous activities, heavy lifting, and swimming for a few weeks. Patients should also avoid exposing the eye to dust and dirty environments.

Vision Improvement
Vision may be blurry initially but should improve within a few days. Complete stabilization of vision can take up to a month. You will work with your doctor during this time to assess your progress.

Protective Eyewear
Wearing sunglasses to protect the eyes from bright light and using an eye shield at night to avoid accidental contact with the eye are recommended.

The Causes of Secondary Glaucoma

Glaucoma is a group of eye conditions that damage the optic nerve – which is an essential part of vision – and is often linked to increased pressure inside the eye. Secondary glaucoma, a type of this condition, arises as a complication of another medical issue or condition. Here’s a closer look at secondary glaucoma, including what it is and its causes and mechanisms.  

Understanding Secondary Glaucoma  

Secondary glaucoma is distinguished from primary glaucoma by its direct association with an identifiable underlying health issue or injury. While primary glaucoma typically develops due to genetic predisposition or age-related changes and lacks a direct cause, secondary glaucoma results from specific pathological conditions that affect the eye’s fluid dynamics or external trauma.  

The balance of aqueous humor production and drainage determines intraocular pressure (IOP) in the eye. Under normal conditions, this fluid is produced in the ciliary body, flows through the pupil, and drains via the trabecular meshwork at the angle where the iris and cornea meet. Any disruption in this flow or drainage can lead to increased IOP, the primary risk factor for optic nerve damage in glaucoma.  

The treatment and management of secondary glaucoma require an understanding of the underlying cause, as addressing this root issue is essential for effective control of the glaucoma itself.  

Common Causes of Secondary Glaucoma  

Eye Injuries  

Trauma to the eye can lead to traumatic glaucoma, a form of secondary glaucoma. Injuries such as blunt or penetrating trauma can disrupt the eye’s natural drainage system, causing fluid buildup and increased IOP. The onset of traumatic glaucoma may be immediate following the injury or can develop gradually over time.  

Inflammation  

Uveitis, an inflammation of the middle layer of the eye (uvea), can obstruct fluid outflow, leading to inflammatory glaucoma. This condition may occur in one or both eyes and is often associated with autoimmune disorders or infections.  

Use of Certain Medications  

Certain medications, particularly corticosteroids used to treat a variety of conditions, can induce glaucoma. Steroid-induced glaucoma is the result of the eye’s increased sensitivity to steroids, affecting its ability to drain fluid properly and maintain a healthy IOP.  

Other Eye Conditions  

Several other eye conditions can also lead to secondary glaucoma, including pseudoexfoliation syndrome, where extra material is produced and sloughs off the lens of the eye and clogs the drainage system. Another is pigment dispersion syndrome, where pigment granules from the iris are dispersed throughout the eye, similarly clogging the drainage angles. However, those are just two examples, as many other diagnoses can increase a person’s risk of developing the condition.  

Risk Factors  

Certain factors can increase the risk of developing secondary glaucoma. These include a history of eye injuries, systemic diseases such as diabetes or hypertension, and the use of medications known to affect intraocular pressure. Genetic predisposition may also play a role in an individual’s susceptibility to certain types of secondary glaucoma.
