YAG Laser Capsulotomy in Moorfields, London

What is YAG Laser Capsulotomy?

YAG Laser Capsulotomy is a quick and painless treatment to restore eyesight to how it was immediately after cataract or refractive lens exchange surgery, where the vision has become blurry due to misting of the capsular bag (termed posterior capsule opacification).

During the treatment, a YAG laser creates a tiny opening in the cloudy capsule, allowing light to pass through clearly again. Most patients notice an immediate improvement in vision, bringing clarity back to the level experienced right after their original surgery.

How Does YAG Laser Capsulotomy Work?

A YAG laser capsulotomy takes about 5 minutes per eye. The laser removes misting on the back of the intraocular lens (IOL) following laser cataract surgery. The misting is termed posterior capsule opacification (PCO), or “secondary cataract” and is relatively common, with up to about 20% of patients who have had cataract or RLE surgery needing this simple procedure within the first few years after surgery.

The treatment is carried out while sitting at a machine similar to the clinic slit-lamp microscope. Local anaesthetic drops are used, and there is no need to worry about blinking or keeping still.

The vast majority of people get an excellent, almost immediate, improvement in their vision following laser without experiencing any issues. Serious side effects are very rare, occurring in less than 1 per 1000 procedures.

How to Prepare for YAG Laser Capsulotomy?

Preparation for YAG Laser Capsulotomy is straightforward. Before your procedure, your eye surgeon will perform a thorough eye examination to confirm that posterior capsule opacification (PCO) is the cause of your blurred vision.

To get ready for treatment:

• Arrange transportation: You may notice temporary blurred vision immediately after the procedure, so you cannot drive home after.
• Follow pre-procedure instructions: You may be asked to avoid wearing contact lenses on the day of your appointment.

The procedure is a fast outpatient treatment performed using local anaesthetic eye drops, and is usually completed in just a few minutes.

Is YAG Laser Capsulotomy Painful? 

Most patients experience no pain during the procedure. You may feel mild pressure or a brief flashing light in your vision, but the treatment is quick and well tolerated.

Is YAG Laser Capsulotomy Safe?

Yes, YAG laser capsulotomy is a very safe and commonly performed procedure with a high success rate. Complications are rare but can include temporary eye pressure changes or minor inflammation, which are easily managed with medication if needed.

What is the Aftercare for YAG Laser Capsulotomy?

After your treatment:

• Vision may be slightly blurry for a few hours, so plan to rest and avoid driving immediately.
• You may be prescribed anti-inflammatory eye drops for a few days to support healing.
• Avoid rubbing your eyes and follow all post-procedure instructions provided by your surgeon.
• Attend any recommended follow-up appointments to check eye pressure and ensure your vision has fully recovered.

Most patients notice clear, improved vision immediately or within a day, and normal activities can usually be resumed the following day.
