Laser Peripheral Iridotomy (LPI)
What is Laser Peripheral Iridotomy?
A precise laser procedure used to treat or prevent angle-closure glaucoma. LPI is an in-clinic procedure performed at EyeHub.
What is laser peripheral iridotomy (LPI)?
LPI is a highly precise laser treatment, targeted at patients with shorter eyes and crowded drainage angles at risk of a spike in eye pressure. The associated conditions are primary angle closure suspects or chronic angle closure glaucoma. It is generally used as a first-line treatment.
LPI is a short, in-clinic procedure performed by our lead ophthalmologist Dr Sonia Moorthy.
We invite you to book an appointment at EyeHub to discuss your treatment options and answer any questions you may have.

What to expect from the LPI procedure
LPI is an in-clinic procedure and takes anywhere between 15-30 minutes. A pressure lowering and numbing drop is applied to the eye that requires treatment.
A lens is then placed on the eye to keep it steady and assist in laser delivery. Laser energy is applied in rapid succession to the peripheral iris (the coloured part of the eye). This creates a microscopic hole, resulting in opening of the drainage angle and better fluid outflow.
At the time of treatment, you may experience some discomfort, but this usually settles.
You will need to have an eye pressure check 15 minutes post procedure. Drops will be required in the treated eye for a week post procedure.

FREQUENTLY ASKED QUESTIONS
Answers to your questions about laser peripheral iridotomy (LPI) treatment
What is laser peripheral iridotomy (LPI), and why is it done?
LPI is a laser procedure used to treat or prevent angle-closure glaucoma. It creates a small hole in the peripheral iris, allowing fluid (aqueous humor) to flow more freely within the eye and reducing intraocular pressure.
Who is a candidate for laser peripheral iridotomy?
LPI is typically recommended for individuals with narrow angles, primary angle-closure, or acute angle-closure glaucoma, as well as those at high risk for these conditions.
Is LPI painful, and what should I expect during the procedure?
The procedure is generally painless, though some patients may feel a brief pinch or discomfort. It is done under local anesthesia (eye drops), takes only a few minutes, and does not require a hospital stay.
What are the risks and side effects of LPI?
Common side effects include temporary blurry vision, mild eye redness, or light sensitivity.
Complications are uncommon, but can include:
- Elevated eye pressure, which may be persistent and require further intervention
- Inflammation of the coloured part of the eye (iritis)
- Bleed in the eye (hyphaema)
- Clouding of the window of the eye (corneal oedema)
