Clear, lasting vision correction is one of the most exciting benefits of LASIK eye surgery. However, achieving those long-term results depends on one critical factor: vision stability. Before undergoing LASIK, it’s essential to understand how stable vision impacts your candidacy and the procedure’s success.
Vision stability means that your prescription has remained consistent over time, typically for at least one to two years. When vision fluctuates, the benefits of LASIK might go to waste as further changes in your eyes can lead to regression or the need for enhancements.
This blog explores everything you need to know about vision stability and LASIK to ensure you meet this fundamental requirement.
What is Vision Stability and How is it Measured?
Vision stability refers to a consistent prescription for glasses or contact lenses over a given period—generally 12 to 24 months. Stability means no further changes in refraction—be it due to errors like nearsightedness or other reasons—will occur.
Long-lasting LASIK results depend on working with a prescription that reflects the eye’s final, stable state. Patients who meet this criterion are far more likely to enjoy sharp, dependable vision for years.
How is Vision Stability Diagnosed?
Eye care professionals use advanced diagnostic tools and comprehensive eye exams to assess vision stability. Some techniques include:
- Standard eye exams. Frequent exams provide a historical record of prescription changes, helping determine whether your vision has stabilized.
- Corneal mapping. This technology creates a detailed map of the cornea, revealing any irregularities that may indicate ongoing changes.
- Wavefront analysis. Wavefront-guided technology captures precise data about how light travels through your eye, ensuring that even minor fluctuations are detected.
These diagnostic methods ensure LASIK candidates are well-prepared for the procedure, minimizing risks and maximizing outcomes.
Why Vision Stability Is a Key Factor for LASIK Success
Stable vision is critical for LASIK because the procedure reshapes the cornea to correct existing refractive errors. If your vision’s still changing, the correction from LASIK might no longer match your future needs. This can result in a loss of clarity or require additional procedures.
For instance, a patient whose prescription worsens shortly after surgery may need enhancements or return to wearing corrective lenses. While these situations are rare when stability is confirmed, they highlight the importance of timing your procedure when your vision is steady.
Noting the factors that could affect your vision in the time leading up to your ideal date for the surgery can help keep it stable.
Factors That Can Affect Vision Stability
Various factors can affect vision stability, from hormonal changes to age. This section breaks down each factor so you can watch out for and address it in collaboration with your eye doctor.
Age and Maturity
The first and most crucial factor affecting vision stability is age. Typically, your doctor will advise you to wait until you’re at least 18 years old before undergoing LASIK. That’s because your eyes will fully develop at this age, and vision should be stable.
However, there are still some critical factors to consider regarding age. These are:
- Changes can still occur in your early 20s. While your eyes generally mature and vision stabilizes at around 18, some people may still experience changes until their 20s. This case is more common in people with progressive conditions like myopia.
- Older individuals and age-related changes. Patients over 40 may experience presbyopia or other age-related changes. While LASIK can still correct distance vision, it won’t prevent conditions like presbyopia from developing.
By considering age and prescription history, LASIK surgeons can better assess stability and recommend the optimal time for surgery.
2. Underlying Eye Conditions
The next most obvious factor that might affect your vision’s stability is underlying eye conditions. These conditions can cause various symptoms that can impact vision stability.
Here are other underlying eye conditions that might impact your vision stability and, similarly, your candidacy for LASIK:
- Keratoconus. This eye condition is a progressive case where the cornea becomes thinner and develops a cone-like shape instead of a smooth, dome-like curve. This irregularity can cause distorted vision and increased sensitivity to light. Because LASIK reshapes the cornea, performing the procedure on someone with keratoconus could further weaken the cornea and lead to complications.
- Progressive myopia. Also known as nearsightedness, this condition causes a gradual worsening of distance vision. It occurs when the eyeball grows too long, preventing light from focusing correctly on the retina. Since LASIK corrects vision based on your current prescription, undergoing the procedure while your myopia is still progressing increases the risk of regression, where the vision may deteriorate again over time.
To ensure the best results, eye care professionals recommend waiting until your vision stabilizes. This typically means observing your prescription over one to two years without significant changes. Stabilized vision ensures that LASIK provides a long-lasting correction, minimizing the likelihood of needing future enhancements.
- Dry eye syndrome. This condition occurs when your eyes don’t produce enough tears or the quality of the tears is poor. Dry eye syndrome can lead to discomfort, blurry vision, and an increased risk of infection. Because LASIK temporarily disrupts the corneal nerves responsible for tear production, pre-existing dry eye can worsen after the procedure, potentially leading to prolonged healing and discomfort.
Addressing dry eye syndrome before LASIK is crucial for a smoother recovery and better overall outcomes. Treatments like specialized eye drops, warm compresses, or punctal plugs (which help retain tears) can improve tear production and eye hydration. Once dryness is under control, you’ll be better positioned for a successful LASIK experience.
Thorough pre-operative evaluations ensure these conditions are managed appropriately, paving the way for safe and effective LASIK treatment.
3. Life Events and Hormonal Changes
Not many know that hormone levels in your body can affect vision. Pregnancy hormones, for instance, can alter the shape and thickness of your cornea, causing vision instability. But it’s not just pregnancy that does this.
These hormonal changes can contribute to vision instability as you go through certain life events like:
- Pregnancy and breastfeeding. Hormonal fluctuations during pregnancy can alter the cornea’s shape and thickness, leading to prescription changes. To ensure stability, it’s best to wait at least six months after childbirth or breastfeeding.
- Menopause. Similarly, hormonal changes during menopause can cause dry eyes and subtle shifts in vision. Addressing these factors before LASIK ensures smoother recovery and optimal results.
Ensuring Vision Stability Before LASIK
To improve your LASIK readiness, consider these tips for monitoring and maintaining vision stability:
- Get regular eye exams. Consistent eye exams are essential for monitoring your vision and ensuring it remains stable. Aim to schedule comprehensive eye exams annually so your doctor can check for prescription changes, detect early signs of conditions like dry eye or keratoconus, and evaluate overall eye health.
If you wear corrective lenses, bring them to your appointment to help track your vision history. Keeping up with these exams gives you and your doctor a clear picture of whether your prescription has stabilized and if you’re ready for LASIK.
- Promptly communicate symptoms with your doctor. If you notice unusual changes in your vision, like sudden blurriness, difficulty focusing, or increased sensitivity to light, don’t hesitate to share them with your eye care provider. These symptoms could signal underlying issues, such as dry eye or progressive myopia, affecting your LASIK candidacy.
Open communication helps your doctor address concerns early and create a tailored plan to manage them, improving your overall readiness for LASIK. Keeping a journal of vision-related changes can help you discuss patterns or trends during your visits.
- Maintain healthy eye habits. Simple daily habits can make a big difference in maintaining eye health and promoting vision stability. Some things you can start practicing are:
- Hydrating to support tear production and keep your eyes moist.
- Eating leafy greens, carrots, and omega-3 fatty acids supports corneal and retinal health.
- Limit screen time when possible, and follow the 20-20-20 rule: every 20 minutes, look at something 20 feet away for at least 20 seconds to give your eyes a break.
- Protecting your eyes from UV rays with sunglasses and wearing appropriate eyewear to prevent unnecessary strain.
