Nearsightedness, also known as myopia, is a common cause of blurry vision. People with nearsighted vision see distant objects as blurry and out of focus. They may need to squint at times to try to improve their focus. Nearsightedness is caused by changes in the shape of the eyeball. Sometimes it can occur when there has been a change in the cornea or the lens.
When these problems happen, light entering the eye, focus in front of the retina not on it as is normal. While nearsightedness cannot be prevented, it can be corrected with surgery – with Optical Express as best laser eye surgery provider.

When used to correct nearsightedness, laser surgery uses a laser to correct the shape of the cornea. The goal of the procedure is to restore vision so that corrective lenses are no longer needed.
Not everyone with nearsightedness is eligible for laser surgery. There are some criteria that first must be met. For instance, a candidate’s vision must been stable for at least one year. The patient must have no corneal diseases or abnormalities. If a patient has an irregular astigmatism, they will not be able to have the surgery. People with moderate or severe dry eyes may also not be eligible for surgery. People younger than 18 and pregnant women also may need to wait for this kind of surgery.
Qualifying patients can opt for different types of laser surgery. The two main types are LASIK and PRK. LASIK makes a small flap in the cornea. Then the tissue beneath it is removed. This particular procedure is quick and has an equally quick recovery time. PRK is a bit more invasive. With this procedure, the cornea’s surface is removed so that the reshaping of the cornea can occur. Patients undergoing this procedure to cure nearsightedness can expect a longer recovery time and mild pain. Your optician can provide you with more information about these procedures.
