Types of Vision Problems Lasers Can TreatOctober 26, 2018
LASIK and other forms of laser eye surgery have become popular types of treatment for those with a variety of vision problems. Laser treatment has helped millions of people improve their vision and no longer to depend on glasses or contact lenses to perform their daily tasks.
Many of the common vision problems we experience are caused by misshapen corneas, the transparent layer that protects the front of our eyes. There are three common vision problems that occur because of irregular-shaped corneas. LASIK surgery, the most frequent type of laser treatment for eyes, works to correct these problems by reshaping the cornea and improving sight.
I Have Trouble Seeing Things in the Distance
Nearsightedness, or myopia, is the most common eye condition experienced today. For those with myopia, the length of the eye from back to front is too long, and often the cornea is curved too much to properly fit the eye. People with myopia find that objects near to the eye appear clear and easy to see, whereas objects that are further away appear blurry.
Myopia is often diagnosed during the teenage years and begins to stabilize as you reach adulthood. Symptoms of nearsightedness include headaches and eyestrain. Many people with myopia find that the ability to see distant objects worsens during dusk and at night.
I Have Trouble Seeing Things Up Close
Hyperopia, or farsightedness, occurs when the length of the eye is too short, and the cornea is too flat. Those with hyperopia are usually able to clearly see objects that are far away but find that closer objects appear blurry. Hyperopia can make tasks such as reading, drawing, or looking at a computer screen difficult.
Farsightedness can occur at any age but is more common among adults over forty years of age. Children diagnosed with hyperopia often grow out of the condition because their eyes grow bigger as they get older. Symptoms of hyperopia include headaches, squinting, and eyestrain.
Everything Looks Distorted
If you have been diagnosed with astigmatism, this means that your cornea does not have the correct shape necessary for clear vision. The cornea normally has a curve similar to the shape of a soccer ball. Astigmatism occurs when the cornea is flattened and takes on a shape that more closely resembles an egg.
Those with astigmatism will often have blurred vision and objects will have a distorted shape. Headaches, eyestrain, and squinting are also symptoms of astigmatism. Astigmatism is commonly inherited through our genes but can also occur after an eye injury or undergoing eye surgery. People with either myopia or hyperopia often have slight astigmatism as well.
Why Laser Eye Surgery?
LASIK surgery combines the use of two lasers to cut away small pieces of the cornea and give it the desired shape. Choosing laser treatment for vision problems can help improve your eyesight and enable you to see both short and long distances more clearly.
