For you to see properly, the cornea and the lens in your eyes need to refract light rays in order that them to focus on the retina. The retina will likely convert these light rays into impulses and will be delivered to the brain to identify images. However, if the light rays will not be focused on your retina, the images you see will be blurry. This disorder is known as refractive error. To reduce these errors and to help you see better, you need to wear eyeglasses or contacts, or undergo a surgery like LASIK surgery. This will make light rays focus on the retina correctly.
Refractive errors have different types and are brought on by imperfectly shaped eyeballs, corneas, or lens. These types of refractive errors are:
- Astigmatism – this condition happens when the images are appears blurry whether they are close to you or far from you. Symptoms are eye strain and recurring headaches, especially after doing a prolonged visual task like reading or watching television. Astigmatism often manifests early in life, that’s why it is important to have the kids scheduled for an eye exam avoid this sort of vision problems. It can be detected during a regular eye exam using the same instruments or techniques for the detection of nearsightedness and farsightedness. Your eye doctor will perform a Refraction test to determine the amount of astigmatism you have.• Myopia or nearsightedness – within this refractive error, only nearby objects appear clear or distinct as the far objects are blurry or distorted. For those who have nearsightedness or myopia, you usually have difficulty seeing distant road signs and any other distant objects clearly. However, your eyesight is good when you are performing close-up tasks like reading a novel or an article on a computer. Other signs to watch out for are eye strain, squinting, and headaches.• Hyperopia or farsightedness – such things happen when the objects that are far away from you are clear or distinct while the nearby images are blurry or distorted. People with this condition sometimes experience recurring headaches or eye strain. They might also often squint or feel tired when or after performing work at a close range. If you are tired of wearing eyeglasses or contact lenses, you may consider a surgery in order to correct your vision. Among the solutions for these problems is a LASIK or laser-assisted in situ keratomileusis procedure. In this surgery, the doctor will be employing a laser to reshape the cornea – the round dome shaped transparent structure at the front of the eyes. This is done to improve the way a patients’ eye focuses light rays onto their retina.
However, not every person is qualified to undergo LASIK surgery. Here are the standards that need to be met before you choose to undergo this treatment:
• You must have healthy eyes.
• Your overall health has to be of good condition. Patients who may have health conditions such as rheumatoid arthritis, diabetes, lupus, herpes infections of the eye, glaucoma, cataracts, retinal disease, and disorders of the cornea may not be suitable to undergo LASIK. When you have any of these conditions, ask your medical professional what other options you have to treat your eyes.
• Your eye prescription need to be stable
• You should be at least 18 years of age. If you are younger than 18 then there’s still a chance that your vision or eye condition will change.
• You must not be nursing or pregnant. People who are expecting or nursing may have varied measurement of their eye degree.
• You ought not to be taking medications such as oral prednisone or Accutane.
• You should not have severe dry eye condition. If you are taking medications that can result in dry eyes, ask your eye specialist about since it can affect the outcome of LASIK.
