Refractive surgery can lead to a life free from glasses, but not everyone is a candidate. Factors like corneal thickness and overall eye health influence your suitability.
Refractive surgery can offer life-changing benefits and a pathway to glasses-free vision, but not every patient is an ideal candidate for procedures like LASIK, PRK, or SMILE. Some individuals face unique ocular characteristics or broader systemic challenges that can limit their suitability for these surgeries. By understanding what prevents some patients from undergoing refractive surgery, you can be better informed and work with your eye doctor to choose the safest, most effective treatment plan.
The foundation of many refractive procedures is the reshaping of the cornea. For surgeries like LASIK, the laser ablation requires a healthy amount of corneal tissue that is both uniformly thick and regular in shape. If your corneas are too thin or abnormally curved, then the removal of tissue may compromise structural stability and increase the risk of complications such as flap-related issues or post-surgery ectasia.
Here’s what your eye doctor will assess:
In cases where these factors are less than ideal, procedures such as photorefractive keratectomy (PRK) might be considered as they remove only the outer epithelial layer while leaving most of the cornea intact, although they often come with a longer recovery period.
Age plays a significant role in determining whether refractive surgery is a viable option. Individuals who are younger and have stable vision correction needs are typically ideal candidates. However, as patients reach their 40s and beyond, subtle age-related changes in the eye can complicate the picture.
Key age-related factors include:
An optimal ocular surface is critical for precise measurements during the pre-surgical evaluation. Conditions such as dry eye syndrome can lead to distorted readings of the tear film, resulting in an inaccurate assessment of your eye’s optical properties.
Before undergoing refractive surgery, your eye care provider will assess:
Addressing dry eye and related conditions with topical medications or other interventions before surgery not only protects your eye’s optical quality but also contributes to a more predictable surgical result.
If you have been wearing contact lenses on a long-term basis, your corneas may adapt and exhibit temporary changes in curvature or thickness. This phenomenon is especially important because even subtle corneal alterations can lead to skewed measurements during the preoperative evaluation.
Your eye doctor may advise you to stop wearing contact lenses for a couple of weeks before an evaluation. This waiting period allows your corneas to revert to their natural shape and ensures that all diagnostic tests, such as topography and refraction, are as accurate as possible.
For some patients, the uncertainty about refractive surgery candidacy can be alleviated with a trial simulation using contact lenses. These temporary lenses help simulate the outcomes you might expect after surgery. By experiencing improved vision without glasses or long-term contacts, you can decide if surgical correction seems beneficial.
This trial period also gives your eye doctor valuable insight into your overall tolerance and adaptation to a new visual correction method, guiding the recommendation for surgery or alternative treatments.

Your overall health is as important as the specific measurements of your eyes when considering refractive surgery. Systemic conditions such as diabetes or autoimmune disorders can affect how well your tissues heal after surgery.
When evaluating your candidacy, your eye doctor will carefully consider:
Refractive surgery can greatly improve your vision and lessen dependence on glasses or contact lenses. However, it cannot prevent future age-related changes like presbyopia or the eventual development of cataracts. This understanding is crucial for setting realistic expectations from the outset.
Your eye doctor will discuss how your eyes might continue to change over time, ensuring that you appreciate the importance of continued eye care and regular follow-up visits after the procedure. This comprehensive approach to long-term ocular health builds trust and underscores the need for collaborative care even after surgery.
One of the reasons some patients do not pursue refractive surgery is that the conversation may not be initiated early enough during routine eye exams. When an optometrist brings up the possibility of refractive surgery proactively, it demonstrates that they stay current with new technologies and options, and positions them as a comprehensive resource for all your vision correction needs.
Initiating this discussion helps:
Beyond the medical and anatomical factors, non-medical issues can also prevent patients from undergoing refractive surgery. Financial concerns, geographic limitations, and systemic barriers within the healthcare system are significant factors that can make surgery seem out of reach for some individuals.
Some of the nonclinical barriers include:
Emerging solutions such as telemedicine consultations and subsidized surgical programs are beginning to address these barriers, but they may not yet be widely available in every community.

Refractive surgery, including LASIK, offers new paths to glasses-free vision, but candidacy depends on individual factors and eye health.
