YAG Laser Treatment Following Cataract Surgery


Can My Cataracts Grow Back After Surgery?

Having cataract surgery may feel confronting, as we agree that our eyes are precious. One of the most frequently asked questions we hear is “Can my cataracts grow back?” And although they cannot ‘grow back’, other opacities can occur following surgery that might require treatment.

What Happens During Cataract Surgery?

During surgery, an intraocular lens (IOL) is placed within the eye. The artificial lens sits inside a natural bag called the lens capsule. Intraocular lenses are designed to last a lifetime and you should also expect the results of your cataract surgery to remain stable.

Why Your Vision Might Become Blurred Again Following Surgery

However, approximately 30% of patients who undergo cataract surgery will develop posterior capsule opacification (PCO). It can cause significant visual symptoms and is often referred to as a “secondary cataract.” PCO occurs due to the formation and movement of epithelial cells that causes the capsular bag to become cloudy. This is more likely to develop in younger patients.

Treatment For PCO is Simple!

The good news is that PCO can be easily treated with a laser. It is a quick five minute procedure performed in a clinical room.  Your ophthalmologist will use an anaesthetic eye drop to numb your eyes. This procedure is known as a YAG laser treatment. Once the PCO is treated with laser, it is extremely rare for it to reoccur. Vision in the eye will recover very quickly following treatment.

Most patients will notice a significant improvement by the next day. However, due to the effects of the dilating drops, you will not be able to drive for 2-4 hours following the treatment. Few people may experience a red, sore eye for a day or two after the procedure, but in most cases there is no pain. You can expect to see ‘floaters‘ as small shadows across your vision afterwards. These usually disappear within weeks.

Complications following PCO treatment are rare but may include:YAG LASER AFTER CATARACT SURGERY

  • Swelling of the retina (macular oedema) causing blurred vision (This usually improves with time but may require treatment)
  • Damage to the intraocular lens implant
  • Increased eye pressure
  • Retinal detachment

These complications can all be successfully treated if they were to occur.

We understand if you wish to delay your surgery until your symptoms become more prominent. Cataract surgery is usually not urgent. It is safe to delay treatment until you feel comfortable to proceed.

However, your vision will continue to deteriorate over time due to the cataracts and can largely impact your quality of life.

If surgery is delayed for too long, the cataract can become advanced and very dense. This can make surgery more difficult and increase the risk of complications. If you feel that the cataracts are affecting you, then having surgery is a great benefit and you should plan to have them removed before they advance.
