NHS YAG Capsulotomy

At Optegra, our expert ophthalmic surgeons provide YAG laser capsulotomy for NHS patients across our nationwide eye hospitals. This short, pain-free laser procedure clears the clouding of the posterior lens capsule that can develop after cataract surgery, restoring your vision quickly and safely.

What is YAG Laser Capsulotomy?

A YAG laser capsulotomy is a quick, non-invasive procedure that uses a precision laser to clear the capsule, allowing light to reach the back of your eye once more.

What is YAG Capsulotomy?

How do I know if I need NHS YAG laser treatment?

Posterior capsular opacification (PCO) can develop months or years after cataract surgery. If you notice your sight becoming cloudy again, it may feel like your cataract has returned, – but this is a separate and easily treatable condition.

Common posterior capsule opacification symptoms include:

  • Blurred or hazy vision
  • Increased glare or halos around lights
  • Difficulty reading or driving
  • Faded colours or reduced contrast
  • Sensitivity to bright light

If you experience any of these symptoms, your optometrist or GP can refer you to Optegra for NHS YAG laser capsulotomy treatment.

What Happens During YAG Laser Capsulotomy?

YAG capsulotomy uses a sophisticated laser to remove the thickening. This facilitates light to pass through to the back of the eye to help you see clearly. YAG laser treatment lasts only a few minutes and involves no surgical cuts.

Here’s what to expect at your NHS appointment:

  1. Referral: If you think, visit your local optician or GP who can refer you to Optegra for YAG treatment. 
  2. Consultation: You’ll see one of our consultant ophthalmic surgeons, who will assess your vision and confirm that YAG treatment is right for you.
  3. Preparation: Eye drops are used to dilate your pupils and numb your eyes.
  4. Laser treatment: The YAG laser creates a tiny opening in the cloudy capsule behind your lens to let light through again.
  5. Quick recovery: The treatment takes around 5 minutes and is completely painless. However, we do advise patients to wait until the following day to resume normal activities. 

Your Vision After YAG Laser Treatment

After the treatment is finished, your eyes may feel a little dazzled from the laser. Your vision will gradually return over a period of 5 to 10 minutes. Expect your vision to remain blurry for a few hours following treatment, from the dilating drops. 

Most patients notice significant vision improvements within one day of the procedure.

Most patients are fine to return to work the day following treatment.

Typically, it is fine to drive the day after your YAG laser treatment. It is advised not to drive on the day of your YAG laser treatment, because dilating drops will be applied which will blur your vision for a little while.

You may be required to apply drops for a few days after treatment to soothe any inflammation.

Yes, generally it is possible to have both eyes treated on the same day.

No, recovery is fast, and patients can go home shortly after the YAG treatment is complete.

As eye drops are applied your vision may be blurry for several hours after treatment. It’s therefore useful to bring a friend or family member along to your appointment, though not mandatory.

Stronger glasses may help partially however if the thickening is extreme this is unlikely to be of much use. In this event YAG laser capsulotomy is the only solution for vision restoration.

Typically, a thickened capsule will gradually worsen, having a negative impact on your vision over time.
