What happens first?

If you suffer from glaucoma, come in to see one of our experts to discuss whether SLT is the right approach for you. During your consultation, we’ll explore your eye history, and examine your eyes to make sure we have the full picture. You can ask any questions that you have, to help you decide whether you want to go ahead with SLT.

What is SLT laser?

A laser is used to target specific cells in the trabecular meshwork. This is the drainage structure in the eye that is responsible for regulating the flow of aqueous humor. The energy from the laser is selectively absorbed by the pigmented cells in the trabecular meshwork, without causing damage to surrounding tissue. The outcome of SLT is an improvement to the drainage of fluid from the eye, which in turn reduces intraocular pressure.

The Benefits of SLT

  • Notable results within two to three months of treatment
  • A pain-free procedure
  • Reduces intraocular pressure for up to five years
  • Removes the need to use glaucoma eye drops

Treatment options

SLT only takes between five to ten minutes to complete. A laser is applied to the front of your eye to increase the amount of fluid drained from your eye, which in turn lowers eye pressure.

Step 1: Anaesthetic

Our surgeon will give you anaesthetic eye drops

Step 2: Start of the procedure

Once that has taken effect, a special lens will be put on your eye. This will help focus the laser and stop you from blinking. A clear gel is placed between the special lens and your eye, to protect the surface of your eye.

Step 3: During the procedure

Gentle pulses of light are delivered to your eye by a specialised microscope. You may see flashes of light or hear clicking sounds at this point.

Step 4: After the procedure

Your surgeon will remove the special lens from your eye. With treatment complete, you’ll be given anti-inflammatory eye drops to help your eyes settle quickly.

Aftercare

You may still have some residue from the gel around your eye when the surgery is finished. This could cause some blurred vision or make your eyes feel heavy. You may also find that your eyes feel irritable or uncomfortable, and sensitive to light, but that should pass in a few hours. In the week after your surgery, you might notice some floaters in your eye. This is normal and they will disappear over time. You should be able to get back to your usual routine pretty quickly.

8 tips for safe and speedy recovery after SLT surgery

Use prescribed eye drops as directed by your doctor to prevent infection and promote healing.

Avoid rubbing or touching your eyes after SLT laser treatment to minimise the risk of complications.

Wear sunglasses to protect your eyes from bright light and UV exposure during the healing process.
Avoid strenuous activities or heavy lifting for a few days after the procedure to prevent strain on your eyes.
Keep your eyes clean and avoid getting any water or soap in them during the initial healing period.
Avoid wearing contact lenses until your eye doctor gives you the green light to do so.
Attend all follow-up appointments with your eye doctor to monitor your progress and ensure proper healing.

Rest as much as you can. Resting allows your eyes to heal and reduces the risk of complications.
