Why have SLT laser?
SLT treatment is a safe and effective option for managing certain types of glaucoma or ocular hypertension. The procedure involves using a laser to target specific pigment cells in the drainage system of the eye, promoting better fluid outflow and reducing intra-ocular (eye) pressure. The effect of SLT is comparable to daily use of one glaucoma drop and may reduce or eliminate the need for glaucoma drops in some patients.
Benefits:
1. Effective in reducing intra-ocular pressure: SLT laser treatment has been shown to be effective in reducing intra-ocular pressure in patients with open-angle glaucoma or ocular hypertension.
2. Non-invasive procedure: Unlike traditional glaucoma surgeries, SLT laser treatment is a non-invasive procedure that does not require any incisions or stitches.
3. Minimal downtime: Following the procedure, most patients can resume their daily activities almost immediately without any restrictions.
4. Long-lasting results: SLT laser treatment can provide long-lasting results, reducing the need for eye drops or other medications to control intra-ocular pressure.
Risks:
1. Temporary increase in intra-ocular pressure: Following the procedure, some patients may experience a temporary rise in eye pressure, which typically resolves on its own within a few days.
2. Eye discomfort: You may experience mild discomfort or a foreign body sensation during or after the procedure, but these symptoms are usually temporary and can be managed with medication.
3. Eye inflammation: In rare cases, SLT laser treatment may lead to inflammation in the eye. This can usually be treated with anti-inflammatory eye drops.
4. Changes in vision: Although rare, SLT laser treatment can cause temporary changes in vision, including blurred or hazy vision. These changes are usually short-lived and resolve within a few days.
5. Need for additional treatment: SLT laser treatment may not be effective for everyone, and some patients may require additional treatments or procedures to adequately manage their condition.
How do I prepare for the procedure?
You can take all your usual medication.
Avoid wearing eye makeup to avoid it being smudged.
Make arrangements for transportation after the procedure, as your vision may be temporarily affected. It is recommended to have someone accompany you or arrange for a taxi service to ensure a safe trip back home.
Points to note:
The procedure is carried out in the eye clinic.
You should expect to be in the eye clinic for approximately two hours
What will happen?
When you arrive at the clinic your vision will be assessed and drops will be put into your eye(s) to constrict the pupils. The doctor or optometrist will explain the procedure and get you to sign your consent form
The procedure
You will be taken into the laser room, where you will sit at a machine with a chin and headrest similar to the examination equipment in the clinic. Anaesthetic drops will be instilled to numb the eye before a special contact lens is placed to help focus the laser precisely on the targeted area.
The laser pulses are painless and typically last only a few nanoseconds. You may notice flashes of light or a slight tingling sensation during the procedure, but these sensations are generally well-tolerated. The treatment usually takes around 5-10 minutes per eye to complete.
What happens afterwards?
Your vision may be blurred for a few hours to a few days after the laser treatment. Your eye may be slightly red or irritated for a short period of time. You may be prescribed eye drops or other medications to aid in healing and prevent inflammation or discomfort. A follow-up appointment would be made a few weeks after the procedure to check your response to the treatment.
