What to Expect After SLT

Recovery after glaucoma laser treatment

Selective Laser Trabeculoplasty (SLT) is a minimally invasive glaucoma laser treatment used to lower eye pressure in patients with open-angle glaucoma and ocular hypertension. Recovery after SLT is usually straightforward, with most patients able to return to normal activities shortly afterwards. At Eye & Laser Surgeons in Sydney, Dr Shanel Sharma and Dr Daya Sharma provide comprehensive glaucoma assessment, laser treatment and follow-up care.

SLT is a quick in-clinic procedure with minimal downtime.

Many patients are surprised by how straightforward the recovery process is compared with traditional glaucoma surgery.

Immediately after SLT

Immediately after the procedure:

  • vision may appear slightly dim or blurred
  • mild light sensitivity may occur
  • some patients notice a mild gritty sensation

These symptoms are usually temporary and often settle within several hours.

Most patients are able to return home shortly afterwards.

Can I drive after SLT?

Many patients are able to drive after SLT once their vision has settled.

However:

  • vision may be blurred usually for less than 15 minutes
  • sensitivity to bright light can occur
  • comfort varies between individuals

You should only drive when your vision feels clear and your ophthalmologist confirms it is safe.

Patients who are uncertain may prefer to arrange transport home after the procedure.

What happens during the first 24 hours?

During the first day after SLT:

  • mild redness may occur
  • the eye may feel slightly irritated
  • vision fluctuations are possible

Most people are able to:

  • work
  • read
  • use screens
  • return to normal daily activities the same day or the following morning.

How long does SLT take to work?

SLT does not usually lower eye pressure immediately.

Pressure reduction typically occurs gradually over 6 weeks.

This is because the laser stimulates a biological response in the trabecular meshwork that improves fluid drainage over time.

Follow-up after SLT

A follow-up appointment is usually arranged to:

  • measure intraocular pressure
  • assess the response to treatment
  • monitor the optic nerve and visual fields

Glaucoma follow-up may include:

  • OCT imaging
  • visual field testing
  • eye pressure measurement
  • optic nerve assessment

What side effects can occur after SLT?

SLT has a strong safety profile and serious complications are uncommon.

Possible temporary side effects include:

  • mild redness
  • irritation
  • blurred vision
  • light sensitivity
  • temporary eye pressure rise

Most side effects are mild and settle without long-term problems.

When should I contact my ophthalmologist?

You should seek review if you experience:

  • worsening pain
  • significant vision loss
  • increasing redness
  • nausea or vomiting
  • severe light sensitivity

These symptoms are very uncommon but may require urgent assessment.

How long does the effect of SLT last?

The pressure-lowering effect of SLT varies between individuals.

Many patients experience:

  • pressure reduction lasting 1–5 years
  • reduced reliance on glaucoma drops
  • the ability to repeat treatment if needed

Some patients may still require:

Can SLT be repeated?

Yes.

Unlike some older laser procedures, SLT is repeatable with no definite limit.

This means repeat treatment is often possible if eye pressure rises again over time.

Why are more patients choosing SLT in Sydney?

Interest in SLT has increased significantly following large clinical studies showing:

  • effective pressure reduction
  • reduced dependence on drops
  • lower rates of glaucoma progression

Patients often appreciate:

  • the short treatment time
  • minimal recovery
  • evidence-based approach

At Eye & Laser Surgeons in Sydney, Dr Shanel Sharma and Dr Daya Sharma provide comprehensive glaucoma care using modern imaging and laser technology.

Frequently Asked Questions

Is recovery after SLT painful?

Most patients describe recovery as comfortable or only mildly irritating. Significant pain is uncommon.

How long is vision blurry after SLT?

Some patients notice mild blur or dim vision for several hours after treatment. This usually improves quickly.

Can I exercise after SLT?

Most patients can return to normal physical activity shortly afterwards unless advised otherwise by their ophthalmologist.

Will I still need glaucoma drops?

Some patients remain drop-free for years after SLT, while others still require drops or combined treatment. More information noted on the SLT Vs glaucoma eye drops link.

Can SLT cure glaucoma?

No. SLT lowers eye pressure but does not cure glaucoma. Ongoing monitoring remains important.
