Selective Laser Trabeculoplasty (SLT)
Harley Street, London
Selective Laser Trabeculoplasty (SLT) represents one of the most significant advances in glaucoma treatment, offering patients an effective, gentle, and repeatable option for reducing intraocular pressure. This innovative laser treatment has revolutionised glaucoma care by providing excellent pressure reduction with minimal side effects and no permanent structural changes to the eye.
Miss Shreya Haldar’s expertise with SLT technology ensures that patients receive optimal treatment outcomes whilst experiencing minimal discomfort and rapid recovery. This advanced laser therapy often serves as an excellent first-line treatment or valuable addition to medical therapy, reducing the burden of daily eye drops whilst effectively controlling glaucoma progression.
Understanding SLT Technology
SLT uses a special frequency-doubled, Q-switched Nd:YAG laser that selectively targets pigmented cells in the trabecular meshwork without causing thermal damage to surrounding tissues. This selectivity is the key to SLT’s success and safety profile.
The laser energy is selectively absorbed by melanin-containing cells within the trabecular meshwork, stimulating a biological response that improves aqueous outflow. Unlike older laser treatments that caused thermal damage and scarring, SLT preserves the structural integrity of the trabecular meshwork.
This selective targeting means that SLT can be safely repeated if necessary, making it an excellent long-term treatment option for glaucoma patients. The procedure’s reversible nature provides flexibility in glaucoma management strategies.
How SLT Works
The trabecular meshwork is the eye’s primary drainage system for aqueous humour. In glaucoma, this drainage system becomes less efficient, leading to increased intraocular pressure. SLT works by stimulating cellular changes that improve the trabecular meshwork’s drainage capacity.
Biological Mechanism
SLT triggers a cascade of biological responses within the trabecular meshwork. The laser energy stimulates the release of cytokines and other signalling molecules that attract immune cells to the area. These cells remove debris and cellular waste that may be blocking drainage pathways.
The treatment also appears to stimulate the division of trabecular meshwork cells, potentially replacing older, less efficient cells with newer, more functional ones. This cellular renewal contributes to improved drainage function.
Pressure Reduction Effects
Studies consistently demonstrate that SLT can reduce intraocular pressure by approximately 20-30% from baseline levels. This reduction is often sufficient to reach target pressures in many glaucoma patients, particularly those with mild to moderate disease.
The pressure-lowering effect of SLT typically develops gradually over several weeks following treatment. Peak effectiveness is usually achieved within 6-12 weeks, with effects lasting for years in many patients.
Advantages of SLT Treatment
SLT offers numerous advantages over traditional glaucoma treatments, making it an attractive option for many patients seeking effective pressure control with minimal lifestyle impact.
Non-Invasive Nature
SLT is performed entirely with laser energy, requiring no incisions or surgical intervention. This non-invasive approach eliminates the risks associated with surgical procedures whilst providing meaningful pressure reduction.
The absence of incisions means there’s no risk of infection, bleeding, or other surgical complications. Patients can resume normal activities immediately following treatment.
Excellent Safety Profile
The selective nature of SLT energy absorption means that surrounding healthy tissue remains undamaged. This safety profile makes SLT suitable for a wide range of patients, including those who may not be candidates for traditional surgery.
Serious complications from SLT are extremely rare. The most common side effect is temporary mild inflammation that resolves quickly with anti-inflammatory eye drops.
Repeatability
Unlike older laser treatments that cause permanent structural changes, SLT can be safely repeated if its effects diminish over time. This repeatability provides long-term flexibility in glaucoma management.
Most patients can undergo SLT retreatment if necessary, often achieving similar pressure reductions to their initial treatment. This makes SLT a valuable long-term management tool.
Medication Reduction
Many patients experience significant reductions in their glaucoma medication requirements following SLT. Some can eliminate medications entirely, whilst others require fewer drops with reduced side effects.
This medication reduction improves quality of life and reduces the cost burden of glaucoma treatment. The elimination of medication side effects is often as valuable to patients as the pressure reduction itself.
Ideal Candidates for SLT
SLT is appropriate for many glaucoma patients, particularly those seeking alternatives to multiple daily medications or those experiencing side effects from glaucoma drops.
Primary Candidates
Patients with primary open-angle glaucoma or ocular hypertension are ideal candidates for SLT. The treatment is particularly effective in eyes with pigmented trabecular meshwork, which is typical in most adults.
Those experiencing difficulty with medication compliance, side effects from glaucoma drops, or the burden of multiple daily medications benefit significantly from SLT treatment.
Treatment Timing
SLT can be used as first-line therapy, often before starting medications, or as adjunctive treatment to enhance the effectiveness of existing medications. Recent studies support its use as initial treatment in newly diagnosed glaucoma.
The procedure is also valuable for patients whose glaucoma isn’t adequately controlled with medications but who aren’t ready for traditional surgery.
Special Considerations
SLT is particularly beneficial for younger patients who face decades of glaucoma treatment. The ability to delay or reduce medication use whilst maintaining good pressure control is especially valuable in this population.
Patients with allergies to glaucoma medications or those experiencing significant side effects find SLT an excellent alternative treatment option.
The SLT Procedure Experience
SLT is performed as an outpatient procedure in Miss Haldar’s clinic, requiring no special preparation beyond routine eye drops to constrict the pupil and numb the eye surface.
Pre-Treatment Preparation
Patients receive topical anaesthetic drops to ensure comfort during the procedure. A special contact lens is placed on the eye to focus the laser beam and provide clear visualisation of the trabecular meshwork.
The procedure typically takes 10-15 minutes per eye, with the actual laser treatment lasting only a few minutes. Patients remain comfortable throughout the procedure.
Treatment Process
Miss Haldar uses a sophisticated SLT laser system to deliver precisely controlled energy pulses to the trabecular meshwork. The treatment covers approximately 180-360 degrees of the drainage angle, depending on individual needs.
Patients may see brief flashes of light during treatment but experience no pain. The selective nature of the laser energy ensures that only target cells are affected.
Immediate Post-Treatment Care
Following SLT, patients receive anti-inflammatory eye drops to prevent excessive inflammation. Most patients can resume normal activities immediately, though vigorous exercise should be avoided for 24 hours.
Temporary pressure spikes can occur immediately after treatment, so intraocular pressure is monitored for the first few hours following the procedure.
Recovery and Follow-Up
Recovery from SLT is typically rapid and comfortable. Most patients experience minimal discomfort and can return to normal activities within a day.
Short-Term Recovery
Mild eye irritation or light sensitivity may occur for a few days following treatment. These symptoms are generally minimal and resolve quickly with prescribed anti-inflammatory drops.
Patients continue their existing glaucoma medications initially, as the pressure-lowering effect of SLT develops gradually over several weeks.
Long-Term Monitoring
Regular follow-up appointments monitor the treatment response and overall eye health. Intraocular pressure measurements track the effectiveness of treatment over time.
Most patients begin experiencing pressure reduction within 4-6 weeks, with maximum effect achieved by 3 months post-treatment. Medication adjustments are made based on the treatment response.
Expected Outcomes and Success Rates
SLT provides excellent outcomes for appropriately selected patients. Success rates are high, with most patients experiencing meaningful pressure reductions that improve their glaucoma management.
Pressure Reduction Results
Studies demonstrate that approximately 80% of patients experience clinically significant pressure reductions following SLT. The average pressure reduction ranges from 20-30% from baseline levels.
This level of pressure reduction is often sufficient to reach target pressures in mild to moderate glaucoma, potentially eliminating or reducing the need for medications.
Duration of Effect
The pressure-lowering effect of SLT typically lasts 2-5 years, though some patients maintain benefits for longer periods. The gradual nature of effect diminishment allows for planned retreatment when necessary.
Factors that influence duration of effect include baseline pressure levels, glaucoma severity, and individual healing responses.
Medication Reduction Benefits
Many patients can reduce or eliminate glaucoma medications following successful SLT treatment. This medication reduction improves quality of life and reduces treatment costs.
Even partial medication reduction can significantly improve patient comfort and compliance with remaining treatments.
