Symptoms and Causes
Nearsightedness, or myopia, is the primary symptom that leads patients to seek an evaluation for a laser procedure. If you have myopia, you can see objects clearly when they are close, but distant objects appear blurry or hazy.
These symptoms occur because light focuses in front of your retina instead of directly on it. This procedure reshapes the eye to bring that focal point back to the correct location.
Astigmatism is another common condition treated by this advanced technology. It occurs when your cornea is shaped more like a football than a round ball, causing light to scatter.
Many patients suffer from both myopia and astigmatism simultaneously. The laser is programmed to smooth out these irregular curves, providing a crisp outline to everything you see.
One of the subtle symptoms of uncorrected vision is chronic fatigue and “heavy” eyes. When your vision is not perfectly focused, the ciliary muscles inside your eye work overtime to try and pull images into focus.
While glasses help, they can also cause distortion or peripheral blur. Correcting the error at the source through relex smile eye surgery eliminates this constant muscular struggle, leading to a much more comfortable visual experience throughout the day.
For individuals with high degrees of nearsightedness, being “legally blind” without glasses is a significant safety and lifestyle concern.
A clinical evaluation for relex smile is often motivated by the desire to eliminate this vulnerability. The surgery provides a “permanent lens” inside your eye, ensuring you are never left without functional sight.
Poor vision in low light is a major symptom of refractive errors. Because the pupil dilates at night, it allows more light to pass through the irregular edges of the cornea, magnifying the blur.
Unlike older laser techniques that could sometimes worsen night vision, this minimally invasive method preserves more of the cornea’s natural optics, often resulting in superior contrast sensitivity after healing.
The causes of myopia and astigmatism are primarily anatomical. They are determined by the physical shape of your eyeball and cornea.
If your parents wore thick glasses at a young age, you are much more likely to develop similar vision symptoms. Genetic factors influence the thickness of your cornea, the length of your eye, and even your risk for dry eye. Because of this hereditary link, we encourage patients with a family history of high refractive errors to seek a clinical checkup as soon as their vision stabilizes in early adulthood. Knowing your genetic risk allows for a proactive approach to eye laser vision correction.
Not everyone’s cornea is the same thickness, and this is a crucial factor in choosing the right surgery. Some people have naturally thin corneas due to their genetics.
By understanding the physical cause of your corneal profile, specialists can provide a safer alternative that keeps your eye structurally sound.
Our modern environment contributes to the symptoms of eye strain. Constant interaction with smartphones, tablets, and computers forces our eyes into a state of constant “accommodation.” While this doesn’t “cause” the initial refractive error, it makes the symptoms much more debilitating. Professional laser care is designed to meet these modern demands, providing a stable visual result that can handle the stress of a digital lifestyle without the need for constant lens adjustments.
Vision often fluctuates during the teenage years and early twenties as the body grows. This is why surgeons require a stable prescription for at least 12 months. If your vision is still changing, it means the physical causes—like the length of your eye—are still evolving. Performing surgery during this unstable phase would result in a “regression” of symptoms. Waiting for stability ensures that once the relex smile is performed, the result lasts for decades, providing a long-term return on your investment in your sight.

In low light, your pupil opens wider, exposing more of your eye’s refractive errors; correcting these with a laser significantly improves nighttime clarity.
No, astigmatism is a physical shape issue of the eye, though stress can cause eye muscles to twitch or make you more aware of your existing blur.
No, it is a refractive error, meaning your eye is healthy but its dimensions are not perfectly aligned with its focusing power.
No, it is most commonly performed on patients between ages 18 and 40 who want to eliminate their reliance on glasses.
Most patients enjoy permanent results, though your eyes will still undergo natural age-related changes, like presbyopia (needing reading glasses), as you enter your 40s.
