In recent years, laser eye surgery has revolutionised the way people correct their vision, providing a life-changing solution for those tired of relying on glasses or contact lenses. One of the most common questions patients have is, “How long does laser eye surgery last?” In this blog post, we’ll explore the factors that influence the longevity of laser eye surgery and what you can expect after undergoing this transformative procedure.

Understanding Laser Eye Surgery

Laser eye surgery comes in various forms, with three of the most prominent procedures being SMILE (Small Incision Lenticule Extraction), LASIK (Laser-Assisted In Situ Keratomileusis), and PRK (Photorefractive Keratectomy). Each type has its unique characteristics and considerations, but they all share the common goal of improving vision by reshaping the cornea.

Factors Influencing Longevity

Prescription Stability:
The stability of your prescription plays a crucial role in determining how long the effects of laser eye surgery will last. If your vision prescription has remained relatively stable for at least a year, you may be a good candidate for the procedure.

The age at which you undergo laser eye surgery can impact its longevity. Generally, the ideal candidates for the above laser surgery are between the ages of 25 and 45, as the eyes tend to be more stable during this period.

Health of the Cornea:
The health and thickness of your cornea are essential factors. Individuals with a thicker cornea may have better long-term results. Your eye surgeon will assess the condition of your cornea to determine your suitability for the procedure.

Post-Operative Care:
Following your surgeon’s post-operative care instructions is crucial for a successful outcome. Proper care, including using prescribed eye drops and avoiding activities that could irritate the eyes, contributes to the longevity of the surgery.

Individual Variability:
Each person’s eyes respond uniquely to the surgery, and factors such as healing ability and tissue response can influence the long-term outcome.

What to Expect After Laser Eye Surgery

Immediate Improvement:
Many patients experience improved vision almost immediately after the procedure, with optimal results typically achieved within a few days to a few weeks.

Potential Changes Over Time:
While laser eye surgery is designed to provide long-lasting results, some individuals may experience changes in their vision over the years. This can be addressed through enhancements or other vision correction methods. When you have laser eye surgery as a young person it won’t prevent the need for reading glasses which usually comes in the mid 40s. For those already in their 40s-60s we have specific laser strategies than can help with the near as well as the distance vision.


Laser eye surgery, whether SMILE, LASIK, or PRK, has a high success rate and offers a lasting solution to common vision problems.
