What Is SLT & DSLT Laser Treatment?
Selective Laser Trabeculoplasty (SLT) and Direct Selective Laser Trabeculoplasty (DSLT) are modern laser treatments used to lower eye pressure in patients with glaucoma or ocular hypertension. Both treatments target the trabecular meshwork, the eye’s natural drainage system, improving fluid outflow and reducing pressure inside the eye.
SLT uses low-energy laser pulses applied directly to the drainage tissue via a contact lens, while DSLT delivers the same therapeutic effect using an automated, non-contact laser system. In both cases, the laser stimulates a biological response that enhances drainage without damaging surrounding tissue, helping protect the optic nerve and preserve vision.
Types of Glaucoma Laser Treatment
1
Selective Laser Trabeculoplasty (SLT)
SLT is a well-established glaucoma laser procedure that selectively targets pigmented cells in the trabecular meshwork. By stimulating natural cellular regeneration, SLT improves aqueous fluid drainage and lowers intraocular pressure. It is commonly used as a first-line treatment or alongside eye drops and can be safely repeated if needed.
2
Direct Selective Laser Trabeculoplasty (DSLT)
DSLT is an advanced evolution of SLT that delivers laser energy without touching the eye. Using automated image-guided technology, the laser is applied through the limbus to reach the drainage tissue. DSLT offers the same pressure-lowering benefits as SLT with increased comfort, faster treatment times and no contact lens required.

What are the Benefits and Risks of SLT & DSLT?
Your consultant will explain personalised risks and expected outcomes before treatment.
Benefits (vary by procedure):
Effective pressure reduction
Non-surgical and outpatient
Minimal recovery time
Can delay or avoid surgery
Risks/side effects (not exhaustive):
Temporary eye pressure rise
Mild inflammation after treatment

Ongoing monitoring still required
Not Sure If You're Eligible?
Book a comprehensive eye examination to better understand your vision and available treatment options.
Who Is Suitable for SLT or DSLT?
Your surgeon will speak with you about your suitability prior to carrying out the procedure
You may be suitable for glaucoma laser treatment if you:
Have open-angle glaucoma or ocular hypertension
Need better pressure control despite eye drops
Experience side effects or difficulty using drops
Want to reduce long-term medication dependence
Are newly diagnosed and seeking first-line treatment
Suitability is confirmed following a comprehensive glaucoma assessment, including pressure measurements, optic nerve imaging and drainage angle evaluation.

Patient Success Stories
Absolutely exceptional
From my initial consultation on 30th September to my follow up appointment on 28th October having had cataract surgery and multi focal lenses inserted in both eyes I have received exceptional care, kindness and professionalism. The entire procedure has far exceeded my expectations and absolutely everyone in the team have been incredible. I was made to feel special every step of the way which was painless and totally comfortable. I can wholeheartedly recommend Centre For Sight at East Grinstead.

A friend recommended Centre for Sight.
I had two cataracts removed and am delighted with the outcome. All the staff were highly professional, took meticulous care and their work was exemplary. Particular thanks to Adora who was so kind and reassuring throughout. I highly recommend Centre for Sight for anyone considering treatment.
Eventually I went to Specsavers in Egham for some mild driving glasses and the optician looked into my eyes and said that he had never seen such a good job on lens replacements. Best he had ever seen.

As I write this – five days after the first eye was done, I can see clearly! I’m hoping for further improvement as the coming weeks pass.
Overall, the team are extremely professional, all led under the leadership and expertise of Mr Daya. He only has one objective – to make your vision better. And that he has achieved.
Thank you so much.
Best wishes,

Cataract Surgery Performed Expertly.
Cataract surgery performed expertly by Mr Sheraz M Daya on both eyes. Trifocal lense implants in one procedure and I am now glasses free with better than perfect vision. From start to finish the attention to detail, friendly professionalism and expertise of everyone at Centre For Sight was outstanding.
I cannot praise Mr Daya and his team too highly, and would recommend the procedure to anyone. It truly can be life changing.
Many thanks to everyone at Centre For Sight and in particular Mr Daya.
