What to Expect: First 24 Hours After Laser Iridotomy

After laser iridotomy, mild discomfort, blurred vision, light sensitivity, or temporary visual disturbances may occur. Knowing what to expect during laser iridotomy recovery can help you follow your ophthalmologist’s instructions and make the first few days more comfortable.

Laser iridotomy, also known as laser peripheral iridotomy (LPI), is a commonly performed laser procedure for people with narrow angles or certain types of angle-closure glaucoma. The treatment creates a tiny opening in the peripheral iris to provide an alternative pathway for aqueous fluid and help reduce the risk of sudden increases in eye pressure.

Although the procedure is generally quick and performed on an outpatient basis, recovery still requires appropriate aftercare. In this guide, we explain laser iridotomy recovery time, what you may experience during the first 24–48 hours, what you should and should not do, possible side effects, exercise restrictions, and when to contact your eye specialist.

What Is Laser Iridotomy?

Laser iridotomy is a laser treatment used primarily for eyes with narrow angles or those at risk of angle closure. During the procedure, an ophthalmologist uses a laser to create a very small opening in the iris. This opening helps aqueous fluid move more freely and can reduce the risk of an acute rise in intraocular pressure.

Because the treatment is performed with numbing eye drops and does not normally require stitches or general anaesthesia, patients can usually return home after a short period of observation.

Laser Iridotomy Procedure: What Happens?

Before the procedure, your ophthalmologist may use eye drops to prepare the eye and make the treatment more comfortable. The laser is then carefully directed at the peripheral iris to create the small opening.

The procedure itself is generally brief. After treatment, your eye pressure may be checked before you leave. Your doctor may also prescribe anti-inflammatory or pressure-lowering eye drops depending on your individual condition.

Because vision can be temporarily blurred after the procedure, arranging transportation home is advisable if your ophthalmologist recommends that you avoid driving.

What Happens Immediately After Laser Iridotomy?

The first few hours are an important part of laser iridotomy aftercare. Some patients notice temporary changes in the treated eye while it adjusts to the procedure and the medications used around treatment.

You May Experience:

• Blurred vision: Vision may remain slightly blurred for a short period because of the eye drops or treatment.
• Mild stinging or irritation: A temporary burning or gritty sensation may occur.
• Light sensitivity: Bright lights may feel uncomfortable, particularly during the first few hours.
• Mild headache or eye ache: Some patients may experience temporary discomfort.
• Glare, halos, or a shadow: Temporary visual phenomena can occur as the eye adjusts.
• Eye redness or watering: Mild irritation and watering may occur after treatment.

Your ophthalmologist may check your intraocular pressure after the procedure to make sure it has remained within a safe range. Follow the monitoring and medication instructions provided by your eye specialist.

Laser Iridotomy Recovery Time: How Long Does It Take?

For many patients, the most noticeable discomfort improves within the first day or two. Mild blurred vision, irritation, light sensitivity, or visual disturbances may sometimes continue for several days.

However, laser peripheral iridotomy recovery time varies from person to person. Your recovery may depend on your eye condition, whether one or both eyes were treated, your response to the laser, and any other glaucoma treatment you are receiving.

Important: Do not judge recovery only by how comfortable your eye feels. Attend the follow-up appointments recommended by your ophthalmologist so that eye pressure and the treated area can be assessed.

Laser Iridotomy Aftercare: What Should You Do?

Following your doctor’s instructions is the most important part of laser peripheral iridotomy recovery. Practical aftercare may include:

• Use prescribed eye drops: Follow the exact dose and schedule provided by your ophthalmologist.
• Give your eyes some rest: If your eyes feel tired or uncomfortable, reduce prolonged reading and screen use during the first day.
• Wear sunglasses: Sunglasses can make outdoor light more comfortable when your eyes are sensitive.
• Avoid rubbing your eyes: Keep your hands away from the treated eye unless instructed otherwise.
• Keep follow-up appointments: Eye-pressure monitoring is an important part of post-procedure care.
• Stay hydrated and maintain your normal healthy diet: Continue your usual balanced meals and adequate fluid intake unless your doctor has advised otherwise.

What Can’t You Do After an Iridotomy?

Many patients ask what they should avoid after laser treatment. Your ophthalmologist’s instructions should always take priority, but common precautions may include:

• Do not rub or press the eye.
• Do not drive until your vision has stabilised and you have been advised that driving is safe.
• Avoid strenuous exercise immediately after treatment unless your ophthalmologist says it is appropriate.
• Avoid heavy lifting or intense physical exertion during the initial recovery period if your doctor has advised restriction.
• Avoid eye makeup while the eye is irritated or until your doctor says it is safe to resume.
• Do not stop prescribed eye drops on your own.

Can I Exercise After Laser Iridotomy?

This is one of the most common questions about laser iridotomy recovery. Light activities such as gentle walking may be suitable for many patients, but strenuous exercise, heavy lifting, or intense workouts may need to be avoided temporarily.

The exact time when you can return to gym workouts, yoga, running, or other physical activities depends on your individual situation. Ask your ophthalmologist when it is safe to resume your normal exercise routine.

Common Laser Iridotomy Side Effects

Most post-procedure symptoms are temporary, but knowing the difference between expected discomfort and warning signs is important.

Mild and Temporary Symptoms

• Mild eye redness
• Temporary irritation or watering
• Light sensitivity
• Mild headache or eye ache
• Slightly blurred vision
• Glare or halos around lights

These symptoms generally improve as the eye settles after treatment. If symptoms are worsening, severe, or not improving as expected, contact your ophthalmologist.

Laser Iridotomy Risks: When Should You Contact Your Doctor?

Laser iridotomy is generally considered a safe procedure, but complications can occur. Contact your eye specialist promptly if you experience symptoms that are severe, worsening, or significantly different from what you were told to expect.

Seek Prompt Medical Attention If You Experience:

• Severe or increasing eye pain
• Sudden or significant reduction in vision
• Marked redness or swelling
• Eye discharge
• Persistent or worsening halos or flashing lights
• A sudden increase in floaters or black spots
• Any symptom that causes significant concern after the procedure

Do not wait for symptoms to become severe if you are concerned about your vision. Prompt assessment can help identify and manage potential complications.

After Laser Iridotomy: What Happens Next?

Laser iridotomy is an important treatment for eyes with narrow angles, but follow-up care remains important. Your ophthalmologist may monitor your eye pressure and examine the treated area to determine how well the eye is responding.

The follow-up schedule varies depending on your diagnosis and individual risk factors. Some patients may require additional glaucoma treatment or ongoing monitoring even after a successful iridotomy.

Does Laser Iridotomy Hurt?

The eye is usually numbed with drops before the laser treatment. During the procedure, patients may notice pressure, a brief stinging sensation, or flashes of light rather than significant pain.

Some mild soreness, irritation, or headache can occur afterward. If pain becomes severe or continues to worsen, contact your ophthalmologist rather than assuming it is part of normal recovery.

Can You Wash Your Face After Laser Iridotomy?

Follow your ophthalmologist’s specific instructions regarding washing your face and caring for the treated eye. During the early recovery period, be gentle around the eye and avoid rubbing or pressing on it.

Can You Work or Use Screens After Laser Iridotomy?

Many patients can return to normal daily activities relatively quickly, but temporary blurred vision or light sensitivity may make reading, computer work, or prolonged screen use uncomfortable.

If your eyes feel strained, take regular breaks and reduce screen exposure during the first day. Do not resume activities such as driving until your vision is sufficiently clear and you have been advised that it is safe.

Laser Iridotomy Recovery: Important Tips for a Smooth Healing Process

• Follow your prescribed eye-drop schedule.
• Attend all recommended follow-up appointments.
• Protect your eyes from uncomfortable bright light.
• Avoid rubbing or pressing the treated eye.
• Give yourself time to rest if vision is temporarily blurred.
• Ask your ophthalmologist before returning to strenuous exercise.
• Contact your doctor if symptoms become severe or worsen.
