If you've been diagnosed with glaucoma, you're probably asking yourself: what's the best glaucoma treatment for me? For years, the standard answer was eye drops. Daily drops, multiple times a day, for life. But there's a different option now, one that more and more people are choosing first. It's called SLT laser treatment, and for many patients, it can replace daily drops altogether.
What Is the Best Treatment for Glaucoma?
The best glaucoma treatment is the one that lowers your eye pressure safely and fits into your life. Glaucoma damages the optic nerve when pressure inside the eye builds up. Left unchecked, it can lead to permanent sight loss. So treatment focuses on bringing that pressure down and keeping it under control.
Traditionally, you'd start with eye drops. They work, but they come with a catch. You have to remember them every day, sometimes twice a day. Miss a dose and your pressure may rise again. Some people experience side effects such as stinging, redness or blurred vision. Others find the drops expensive or simply inconvenient.
That's where SLT laser treatment changes the picture. It's a minimally invasive procedure that lowers eye pressure without the need for a daily medication routine. It's also recommended as a first-line treatment option, rather than just a backup plan.
Can Glaucoma Be Treated Without Eye Drops?
Yes, it can. SLT, or Selective Laser Trabeculoplasty, treats glaucoma by improving the drainage system inside your eye. Think of it like unblocking a slow drain. The laser targets the trabecular meshwork, the part of your eye that allows fluid to drain away. It stimulates the cells there, helping them work more effectively. Fluid drains more easily, pressure drops, and the risk of further optic nerve damage is reduced.
The procedure usually takes around five minutes per eye. You sit at a machine similar to the one used during an eye test. Your consultant numbs your eye with drops before applying tiny pulses of laser light. You might see flashes of green or feel a slight sensation, but the treatment is generally well tolerated. You can go home the same day.
Most people see their eye pressure begin to drop within a few weeks. The effects typically last between one and five years, although this varies from person to person. If the effect wears off, SLT can often be repeated. Some patients may still need eye drops alongside or after treatment.
Why Choose SLT as a First-Line Glaucoma Treatment?
SLT isn't new, but its role has shifted. It used to be reserved mainly for people who couldn't tolerate eye drops or didn't respond well to them. Now, guidelines from organisations like NICE recognise it as a first-line option for suitable patients. That means you can consider it from the start, rather than waiting until drops have failed.
Why would you choose it? Because it can remove the daily hassle of eye drops. No more setting alarms, fumbling with bottles or worrying whether you've put them in properly. For people who travel, work shifts or simply don't want the burden of lifelong medication, SLT can offer greater convenience and flexibility.
It's also generally well tolerated. Unlike some older laser treatments, SLT is selective and does not intentionally damage or remove the surrounding tissue. Most side effects are mild and temporary. These can include some redness, mild inflammation or a temporary increase in eye pressure. Your consultant will monitor you after treatment and advise if any additional care is needed.
How Does SLT Compare to Eye Drops for Glaucoma?
Let's talk practicalities. Eye drops lower pressure by either reducing fluid production or improving drainage. They're effective, but only if you use them correctly and consistently. Some people find it difficult to maintain a daily routine. Life gets in the way. Bottles run out. Hands shake. Eyes water and wash the drop away before it's absorbed.
SLT offers an alternative. One treatment can provide pressure-lowering benefits for typically one to five years. There's no daily routine to remember, no regular refills and no ongoing exposure to preservatives in eye drops during periods when drops are not required.
Of course, eye drops still have a place. Some people prefer them. Others combine SLT with drops to achieve better pressure control. For many patients, however, SLT can replace daily drops, reducing the need for ongoing medication. Your consultant will help determine the most appropriate approach for your eyes.
Is SLT Right for You?
Not everyone is a candidate for SLT, but many people are. It works particularly well for open-angle glaucoma, the most common type. Your consultant will examine your eyes, check your eye structure, measure your pressure and discuss your medical history. If SLT is suitable, they'll explain what to expect and answer any questions.
At LondonOC, SLT is carried out by Mr Vik Sharma, Lead Glaucoma Surgeon at Royal Free London NHS Foundation Trust, who has performed thousands of SLT treatments since 2010. His extensive experience in glaucoma care allows patients to explore their treatment options with an experienced specialist.
At LondonOC, every patient is seen by a consultant ophthalmologist who specialises in glaucoma. You're not passed between juniors or nurses. You receive expert advice tailored to your eyes, your lifestyle and your goals. That's the consultant-only service that sets us apart.
What Happens After SLT Laser Treatment?
You'll have a follow-up appointment to check your eye pressure and make sure the treatment is working. Most people notice a gradual reduction over the first month. Your consultant will monitor your progress and adjust your treatment plan if needed.
One of the advantages of SLT is that it doesn't close any doors. If your eye pressure rises again after a few years, you may be able to have another SLT session. Alternatively, your consultant may recommend adding eye drops or considering another treatment if necessary.
For many patients, this means the possibility of spending years without the need for daily eye drops. It offers greater flexibility while keeping your glaucoma under careful management.
