Symptoms and Causes
The most common symptom that leads a person to a lasik clinic is persistent blurred vision. Depending on the type of refractive error, this blur can affect your life in different ways. If you struggle to see street signs while driving or find it difficult to recognize faces from across a room, you are likely experiencing myopia. Conversely, if you find that reading a book or looking at your smartphone causes the text to appear fuzzy, hyperopia is the probable cause. These symptoms are signs that your eye’s natural focusing system is not aligned with its physical shape, making daily tasks frustrating and physically tiring.
Distortion is a key indicator of astigmatism, a condition that often accompanies other vision problems. Unlike simple blur, distortion makes objects look stretched, tilted, or smeared.
This happens because the cornea is shaped like a football rather than a round basketball. A professional lasik eye surgery evaluation includes measuring these irregularities to ensure the laser can smooth them out and provide a crisp, clear image.
Many patients ignore the subtle symptoms of eye strain, thinking it is just a result of a long work day. However, chronic headaches, especially around the forehead and temples, are often a symptom of uncorrected or under corrected vision. When your eyes are not focusing correctly, the ciliary muscles inside the eye work overtime to compensate for the blur.
Correcting the sight through lasik eye surgery reduces the physical effort required to see, often leading to a significant reduction in tension based headaches.
Difficulty seeing in low light is a significant symptom that impacts safety. Many people with high prescriptions experience intense glare and halos around headlights and streetlamps at night. This “night blindness” or sensitivity occurs because the large pupil at night allows more light to enter through the peripheral, often more irregular, parts of the cornea. During your evaluation, specialists check your pupil size and how your vision reacts to dim light to ensure that the surgical plan improves your vision in all lighting conditions.
The underlying causes of vision errors requiring lasik are primarily anatomical. They are determined by the physical dimensions of your eyeball and the curvature of your cornea.
These structural traits are largely genetic. If your parents wore glasses at a young age, you are much more likely to develop these symptoms yourself. While lifestyle factors like excessive screen time can contribute to eye strain, the root cause is usually the shape you were born with.
When determining the cause of your visual symptoms, a clinician also looks at the physical health of your cornea. Some patients have symptoms of vision loss but also have naturally thin or irregular corneas. This is where the choice of prk vs lasik becomes vital.
Understanding the physical causes behind your corneal thickness allows the specialist to provide the safest possible path to clear sight.
Age is a universal cause of change in the human eye. While laser procedures are excellent for fixing distance vision, they cannot stop the natural aging of the internal lens, a condition called presbyopia.
Many patients choose to have a “Monovision” or “Blended Vision” treatment where one eye is set for distance and the other for near, allowing them to bypass this age related symptom and maintain independence from reading glasses.
Your environment can be a direct cause of eye discomfort that mimics or worsens vision symptoms. Chronic exposure to dry air, wind, and smoke can lead to dry eye syndrome.
A comprehensive checkup ensures that any dry eye symptoms are treated before your lasik eye surgery to ensure the best possible healing environment. Healthy tears are essential for the clear, high definition vision that the laser is designed to provide.
For many, the “cause” for seeking surgery is the failure of traditional correction in their professional lives.
These occupational needs are recognized as valid reasons for clinical intervention. By treating the anatomical cause of the blur, patients can perform their jobs with greater precision and less risk to their physical safety.
Ignoring worsening vision can lead to secondary problems like amblyopia (lazy eye) in children or increased risk of accidents in adults. Furthermore, sudden changes in vision symptoms can sometimes be signs of other health issues like diabetes or high blood pressure. By seeking a professional evaluation at a facility like Liv Hospital, you are not just looking for a way to get rid of glasses; you are receiving a full health check for your eyes. Early intervention ensures that your eyes remain healthy and that your vision is protected for decades to come.
