We recommend a Laser Peripheral Iridotomy when the drainage angle in the eye is dangerously narrow or if you already have angle‑closure glaucoma. The Nd:YAG laser makes a tiny hole in the outer edge of the iris. This allows fluid behind the iris to flow forward, relieving pressure caused by pupillary block. In glaucoma cases, this helps lower eye pressure and reduce the risk of acute attacks or optic nerve damage. In eyes with narrow angles but no glaucoma yet, it’s done preventively to open the angle and reduce the chance of developing glaucoma in the future.
The procedure takes about 5-10 minutes and is performed in an outpatient setting, allowing most individuals to resume their daily activities almost immediately. Despite these benefits, some patients may experience visual disturbances, such as glare, halos, or mild double vision—commonly referred to as dysphotopsias—following the procedure. There is also a potential for an intraocular pressure (IOP) spike shortly afterward, along with risks of inflammation or minor bleeding (hyphema) in the anterior chamber.
After LPI, the patient will be prescribed topical corticosteroid drops—to use four times a day for about 5 to 7 days—to reduce inflammation inside the eye. Additionally, intraocular pressure (IOP) will be carefully monitored to check for any early pressure spikes that may require prompt attention. Finally, a follow-up gonioscopy (or other angle imaging) is essential a week post-op. This ensures that the drainage angle remains open and confirms that the iridotomy hole is functioning properly. LPI procedure doesn’t cure glaucoma; patients have to come for regular follow-up thereafter as per the doctor’s instructions.
Most laser procedures are not painful. You may feel a slight sting or pressure during the treatment. Numbing eye drops are administered beforehand to minimize discomfort.
The procedure usually takes about 10–15 minutes and is performed on an outpatient basis.
Yes — anti-inflammatory eye drops are typically prescribed for about one week following the procedure to reduce inflammation.
No. Laser treatment does not cure glaucoma; it helps manage the condition by opening the drainage angle and improving fluid circulation.
You may experience slight blurred vision, mild redness, or a headache for a few hours post-procedure. These symptoms usually resolve within 4–6 hours.
Most patients can return to their usual activities within a day.
Laser peripheral iridotomy (LPI) is typically a one-time procedure. However, if the iridotomy becomes small or closes—due to inflammation or pigment buildup—your doctor may recommend a repeat treatment.
Yes. You can safely proceed with cataract surgery after an LPI once your eye has healed.
