How Long Does Laser Eye Surgery Last? What You Need to Know
Laser eye surgery has become a well-known vision correction option for people looking to reduce their dependence on glasses or contact lenses. But how long does laser eye surgery last?
While laser eye surgery can deliver lasting improvements to your vision, the exact duration of results can change depending on many factors, including the type of procedure, your age, and natural changes in your eyes over time.
This guide explains what to expect, how long laser eye surgery typically lasts, and what can influence your long-term results.
Understanding Laser Eye Surgery
Laser eye surgery, also called laser vision correction surgery, refers to a group of laser-assisted procedures designed to change the shape of the cornea and correct refractive errors such as short-sightedness (myopia), long-sightedness (hyperopia), and astigmatism.
During laser refractive surgery, an excimer laser or femtosecond laser is used to reshape the corneal tissue to enhance how light is focused onto the retina. This adjustment can help achieve clearer vision without needing glasses or contact lenses for many daily activities.
Types of Laser Eye Surgery Procedures
Several forms of laser eye surgery procedures exist, each designed to address specific refractive errors and suit different eye conditions.
While all aim to improve how light focuses on the retina, the techniques and recovery experiences can vary. Understanding these distinctions can help you make an appropriate decision during your comprehensive eye exam.
LASIK (Laser-Assisted In Situ Keratomileusis)
LASIK surgery is one of the forms of laser vision correction. A precise laser-assisted instrument creates a thin flap in the cornea during the procedure.
The tissue is then reshaped using an excimer laser to fix refractive errors such as Short-sightedness, Long-sightedness, and Astigmatism. The corneal flap is gently repositioned, allowing it to heal naturally without suturing.
Because the corneal reshaping is performed beneath the surface, LASIK is typically associated with smooth recovery and minimal discomfort. This procedure is often suitable for good candidates who have adequate corneal thickness and stable prescriptions.
PRK (Photorefractive Keratectomy)
PRK, or Photorefractive Keratectomy, was the first widely used form of laser refractive surgery and remains a well-established option. In PRK, the outer layer of the cornea (epithelium) is taken out to expose the treatment area. The underlying tissue is then reshaped with an excimer laser to correct vision. The surface naturally regenerates over the following days.
PRK can be a preferred alternative for individuals whose corneas are too thin for LASIK or those with specific corneal characteristics. Although the initial healing period is slightly longer than LASIK, PRK offers comparable long-term results once the eye fully recovers.
SMILE® (Small Incision Lenticule Extraction)
SMILE®, or Small Incision Lenticule Extraction, is a recent advancement in laser eye treatment. This minimally invasive technique uses a femtosecond laser to make a small lens-shaped piece of tissue (lenticule) within the cornea, which is then taken out through a micro-incision.
Unlike LASIK, SMILE does not involve making a large corneal flap. This may help preserve more of the cornea’s natural structure and may reduce the likelihood of dry eye symptoms for some individuals. Recovery is generally efficient, and the procedure is suitable for correcting short-sightedness and certain cases of astigmatism.
How to Prepare for Laser Eye Surgery
Preparation involves a comprehensive eye exam and discussing your vision problems and lifestyle. You’ll be advised to stop wearing contact lenses before your surgery, as they can temporarily affect your cornea’s shape.
Is Everyone a Good Candidate?
Not everyone is a candidate for laser eye surgery. Factors such as corneal thickness, general health, age, and eye disease can determine whether you’re suitable for LASIK surgery or another type of laser correction.
A comprehensive eye exam is important to determine which procedure best suits your needs.
How Long Does Laser Eye Surgery Last?
For most people, laser eye surgery results last many years. LASIK patients usually enjoy improved vision for at least a decade or longer. However, the duration of your results can vary depending on other factors such as your age, eye health, and lifestyle.
While the corneal reshaping achieved during surgery is permanent, natural changes in the eye, like the development of presbyopia (age-related near-vision loss), can affect your vision later in life.
What to Expect in the First Few Weeks
In the first few weeks after surgery, your vision may fluctuate slightly as your eyes heal. People can return to normal activities within days, but full visual stabilisation can take several weeks to a few months.
Why Results Can Vary
Several factors influence how long your laser eye surgery results last:
- Age at the Time of Surgery: Younger patients may experience more natural vision changes over time.
- Degree of Refractive Error: Those with higher prescriptions before surgery may notice changes earlier.
- General Health and Eye Health Conditions: Conditions like dry eyes, eye disease, or eye injuries can impact results.
- Lifestyle and Habits Eye Strain: UV exposure, or certain occupational environments, can influence long-term clarity.
- Natural Ageing: As you age, your eye’s lens may change, affecting how you see near objects.
Maintaining Clear Vision After Surgery
To help your laser eye surgery results last longer, it’s important to maintain good eye health:
- Attend all follow-up appointments.
- Use eye drops or artificial tears as directed.
- Wear sunglasses to shield your eyes against harmful UV rays.
- Avoid rubbing your eyes excessively.
- Follow your surgeon’s instructions about resuming activities like swimming or using hot tubs.
When to Have a Follow-Up Appointment
Your surgeon will usually schedule follow-up appointments to track your recovery progress. Attending these visits helps your care team ensure your laser eye treatment results remain stable and your eyes are healthy.
Frequently Asked Questions
What if vision changes after surgery?
If your vision changes years after surgery, you may benefit from a LASIK enhancement or follow-up procedure. Your eye surgeon can evaluate your corneal thickness and eye health to determine whether another laser correction is appropriate.
Can vision changes be corrected after surgery?
Yes, if your vision changes over time, a LASIK enhancement or follow-up procedure may help refine your vision.
Can I wear contact lenses again if my vision changes?
Yes. If your vision changes, you can still wear contacts or glasses as needed.
Conclusion
So, how long does laser eye surgery last? The results are long-lasting for many people, with the corneal reshaping remaining permanent. However, your vision may change naturally over time due to ageing or other factors.
Proper care, attending follow-up appointments, and maintaining good eye health can help you achieve clearer vision for many years to come.
