Experiencing Blurry Vision After Cataract Surgery? It Might Be a Normal Change — and It’s Easy to Treat

If you’ve had cataract surgery and are now noticing blurry vision again, or your eye doctor mentioned something called a YAG laser procedure, there’s no need to worry. This is not uncommon, and in many cases, it’s a consequence of how some eyes heals over time.

One possible cause is something called posterior capsule opacification (PCO) — sometimes referred to as “secondary cataracts.” This is not a return of your cataracts, and it’s not the result of anything going wrong with your original surgery.

Instead, some patients experience a cloudy film developing behind the new lens implant — and when that happens, a quick and painless in-office procedure using a laser can help restore clear vision.

At Sweeney Eye Associates, our cataract specialists — Dr. Patrick Sweeney and Dr. Vincent Venincasa — regularly perform this safe and effective procedure for patients across North Texas.

What Are Secondary Cataracts?

After cataract surgery, your natural cloudy lens is replaced with a clear artificial lens (IOL). Over time, some patients develop a cloudy film on the back of the capsule that holds this new lens in place. This condition is called Posterior Capsule Opacification (PCO) — often referred to as “secondary cataracts.”

It’s not a recurrence of the original cataract, but it can cause similar symptoms, including:

  • Blurry or hazy vision
  • Glare or halos around lights
  • Difficulty reading or seeing clearly

PCO is one of the most common side effects of cataract surgery, affecting about 20% to 30% of patients within 2 to 5 years after the procedure, according to the American Academy of Ophthalmology.

What is the YAG Laser Procedure?

To treat PCO, we use a YAG laser capsulotomy — a quick, in-office procedure that uses a laser to create a small opening in the cloudy capsule behind your lens implant. This allows light to pass through clearly again, restoring your vision.

Key Facts:

  • No injections, stitches, or downtime
  • Procedure takes about 5 to 10 minutes
  • Most patients experience improved vision within 24 hours
  • You can return to normal activities the same day

When Should I Consider a YAG Procedure?

Not everyone will need a YAG laser treatment after cataract surgery, but your optometrist or ophthalmologist may recommend it if:

  • Your vision has gradually worsened since your surgery
  • You’re noticing increased glare or difficulty seeing clearly
  • An eye exam confirms clouding of the posterior capsule

This isn’t a reflection of anything going wrong with your initial surgery — it’s simply how the eye heals in some cases, and the fix is straightforward.
