Imagine waking up one day with the fear of losing your sight. That’s what happened to John when he was diagnosed with glaucoma. Glaucoma, a severe eye condition, can lead to vision loss if not treated properly. Understanding the surgery options, risks, and benefits is crucial in making informed decisions about your eye health. In this blog post, we’ll delve into the world of glaucoma surgery, exploring the various procedures, preparation, post-surgery care, and potential risks, benefits, and side effects.
- Glaucoma surgery offers benefits such as slowing progression of the disease and preserving existing vision.
- Risks, benefits, and side effects should be considered before undergoing glaucoma surgery.
- Combining glaucoma & cataract surgeries may provide additional advantages to patients.
Types of Glaucoma Surgery
As glaucoma progresses, surgery may become necessary to help prevent vision loss. There are three main types of glaucoma surgery: laser surgeries, incisional surgeries, and minimally invasive glaucoma surgery (MIGS).
Each type has its own advantages and disadvantages, and the choice depends on the patient’s specific needs and eye condition.
Laser surgeries are a popular option for glaucoma treatment, as they are less invasive and often performed in-office. The goal of these procedures is to improve fluid drainage and reduce eye pressure, which can slow the progression of glaucoma. Argon laser trabeculoplasty (ALT) and selective laser trabeculoplasty (SLT) are two common types of laser surgeries. They are generally used to treat glaucoma. These procedures use a highly concentrated beam of light to help unblock obstructed drainage channels and facilitate the drainage of fluid in the eye.
Laser surgeries, such as laser treatment, are generally associated with less post-operative discomfort than incisional surgeries. Laser trabeculoplasty is an appropriate treatment option to treat open angle glaucoma, while laser peripheral iridotomy (LPI) is suitable for those with closed-angle glaucoma. In this context, surgery for glaucoma can be effectively managed with these laser techniques.
Before deciding on the most suitable laser surgery for your condition, a discussion about the risks, benefits, and expectations with your eye specialist is indispensable.
Incisional surgeries are more invasive than laser surgeries and are performed in an operating room. The main goal of these procedures, including drainage implant surgery, is to create new drainage pathways or implant devices to lower eye pressure and treat glaucoma. Incisional surgeries include:
- Valve surgery
- Seton surgery
Trabeculectomy, also referred to as filtering surgery, involves using small instruments to excise a section of the eye wall, creating a small hole covered by conjunctiva (the layer around the eye). Another option is tube shunt surgery, where a small tube is inserted into an opening created between the cornea and sclera to reduce intraocular pressure.
Before deciding on the most appropriate incisional surgery for your specific needs, consulting with your eye specialist about the pros and cons is vital.
Minimally Invasive Glaucoma Surgery (MIGS)
Minimally invasive glaucoma surgery (MIGS) is a cutting-edge technology that uses tiny instruments and devices, resulting in smaller incisions and faster recovery time. MIGS offers the following benefits:
- Safer and less invasive option for patients with early to moderate-stage glaucoma
- Modest reduction in eye pressure
- Faster recovery time compared to traditional glaucoma surgeries
While MIGS is generally considered safer than traditional glaucoma surgeries, it may not be as effective in achieving the low eye pressures necessary for advanced glaucoma. MIGS procedures are generally used in conjunction with cataract surgery. This is mainly for patients suffering from early to moderate stage of glaucoma..
It’s of utmost importance to consult your eye specialist to determine whether MIGS is the right option for you, considering your specific eye condition and needs.
Preparing for Glaucoma Surgery
Before undergoing glaucoma surgery, there are several steps you need to take to ensure a successful procedure and recovery. These include:
- Consulting with an eye specialist
- Making the necessary medication adjustments
- Preparing for the day of surgery.
Consultation with Eye Specialist
Prior to any glaucoma surgery, you must consult with an ophthalmologist, or eye doctor, to discuss your specific needs, risks, benefits, and expectations. During the consultation, your eye specialist will:
- Review your medical history
- Perform a comprehensive eye examination
- Explore treatment options
- Recommend the most suitable surgery for your condition.
Topics to discuss during your consultation for glaucoma surgery include:
- Success rate
- Potential complications
- The specialist’s experience
- Alternative options to lower eye pressure
- Timing and scheduling of the surgery
- Any particular concerns or questions you may have
This consultation is a key step in ensuring the best possible outcome for your glaucoma surgery.
Before glaucoma surgery, you may need to:
- Adjust or discontinue certain medications
- Discontinue certain topical ocular medications
- Abstain from medications that can raise intraocular pressure, such as tricyclic antidepressants, decongestants, and antihistamines.
Managing blood thinners before surgery is also important, as they can increase the risk of bleeding during and after the procedure. Your eye specialist will provide specific instructions on necessary medication adjustments to ensure a safe and successful surgery.
Day of Surgery
On the day of your glaucoma surgery, it’s important to follow the instructions provided by your healthcare provider or surgical team. This typically includes fasting on the day of the procedure, as consuming any food or beverages beforehand can cause complications.
Arrive at the surgical center at the recommended time, wearing comfortable, loose-fitting clothing and avoiding perfume, cologne, makeup, and jewelry. Button-down shirts or blouses are preferred. Following these guidelines will help ensure a smooth surgery and minimize the risk of complications.
Post-Surgery Recovery and Care
Following your eye specialist’s guidelines for recovery and care after glaucoma surgery is paramount. This includes attending follow-up appointments, using prescribed eye drops and an eye patch, and adhering to activity restrictions.
It is important to take these steps seriously, as they can help ensure a successful recovery and reduce
Regular check-ups with your eye specialist are essential after glaucoma surgery. These follow-up appointments typically occur within the first six weeks after surgery and help monitor vision, eye pressure, and the healing process.
During these appointments, your eye specialist will perform various tests and evaluations to ensure your eye is healing properly and that the surgery was successful. It’s crucial to attend all follow-up appointments as recommended by your ophthalmologist to achieve optimal outcomes.
Eye Drops and Patch Use
After glaucoma surgery, your eye specialist may prescribe eye drops and/or an eye patch to aid in recovery and prevent complications. Eye drops can help reduce inflammation, prevent infection, and lower intraocular pressure.
Using eye drops as instructed by your doctor is crucial, which typically involves stopping the use of glaucoma drops in the operated eye and maintaining the same times and dosage for the non-operated eye. The correct use of eye drops and an eye patch is vital for a successful recovery.
To ensure proper healing after glaucoma surgery, certain activity restrictions and lifestyle adjustments may be necessary. During the initial four to six weeks following surgery, it’s recommended to avoid strenuous activities such as:
- ball sports
- gym workouts
Gentle walking, however, is usually acceptable.
In addition to limiting physical activities, you may need to make lifestyle adjustments, such as avoiding inversions in yoga, altering sleep, exercise, and diet habits, and incorporating aerobic exercise and mindfulness meditation. Following these guidelines and allowing for sufficient recovery time will help ensure the best possible outcome after your glaucoma surgery.
