YAG Laser Eye Surgery: What It Is & Who It’s For

By David Anderson

YAG laser eye surgery, or Yttrium Aluminium Garnet laser eye surgery, is a common and highly effective procedure primarily used to treat posterior capsule opacification (PCO), a complication that can arise after cataract surgery. 

This surgery is a straightforward outpatient procedure that significantly improves vision by addressing the clouding that can develop in the lens capsule, where an artificial lens has been placed.

What is YAG Laser Eye Surgery?

YAG laser eye surgery involves using a specialised laser to create a small opening in the cloudy capsule. 

This opening allows light to pass through the lens properly, thereby restoring clear vision. The procedure is quick, usually taking only a few minutes, and is performed under local anaesthesia.

Patients typically experience little to no discomfort, and recovery is swift, with most individuals resuming normal activities almost immediately.

Who is Suited for YAG Laser Eye Surgery?

This procedure is particularly suitable for patients who have previously undergone cataract surgery and are experiencing a decline in vision due to PCO. 

Symptoms of PCO include blurred vision, glare, and difficulty seeing in bright light. 

It is essential for patients to have a comprehensive eye examination to confirm the presence of PCO and determine the appropriateness of YAG laser eye surgery.

In addition to those with PCO, individuals with certain types of glaucoma may also benefit from YAG laser procedures, as it can be used to create a small hole in the iris to improve fluid drainage and reduce intraocular pressure.

How Does YAG Laser Eye Surgery Compare to Other Types of Laser Eye Surgery?

While YAG laser eye surgery is a post-cataract procedure, other types of laser eye surgeries, such as LASIK and PRK, are primarily performed to correct refractive errors like myopia, hyperopia, and astigmatism.

LASIK (Laser-Assisted In Situ Keratomileusis): LASIK involves creating a thin flap in the cornea and using a laser to reshape the underlying tissue.

This reshaping corrects the refractive error, allowing light to focus correctly on the retina. LASIK is renowned for its quick recovery time and immediate improvement in vision. 

However, it is not suitable for everyone, particularly those with thin corneas or certain eye conditions.

PRK (Photorefractive Keratectomy): PRK, like LASIK, reshapes the cornea but does so without creating a flap. Instead, the outer layer of the cornea is removed entirely, and the underlying tissue is reshaped with a laser. 

The recovery time for PRK is longer than that of LASIK, and patients may experience more discomfort during the healing process. 

PRK is often recommended for individuals with thinner corneas or those who are not suitable candidates for LASIK.

YAG Laser Eye Surgery: Unlike LASIK and PRK, YAG laser eye surgery is not performed to correct refractive errors but to address the secondary issue of PCO following cataract surgery.

Its role is more about maintenance and restoration of vision post-cataract removal rather than primary vision correction.

In summary, YAG laser eye surgery is a highly effective, minimally invasive procedure designed to treat complications arising after cataract surgery, particularly PCO.

It offers a quick and painless solution to restore vision clarity, making it an invaluable tool in modern ophthalmology.

For those considering laser eye surgery, it is crucial to have a detailed discussion with an ophthalmologist to determine the most suitable procedure based on individual eye health and vision needs.
