<p>The most common type of refractive surgery is called <strong>LASIK</strong> (laser-assisted in situ keratomileusis). Most types of refractive surgery, including LASIK, use lasers to change the shape of the cornea. Some use other tools, like implants.</p>

<p>LASIK uses a laser (a strong beam of light) to change the shape of the cornea and help make vision clearer. It works best for adults with nearsightedness, farsightedness, or astigmatism. It can’t fix presbyopia. For LASIK to work correctly, your vision needs to be stable (meaning your eyeglass or contact lens prescription stays the same over time).</p>

<p>To find out if LASIK is right for you, you’ll need a comprehensive dilated eye exam. The exam is simple and painless. Your eye doctor will ask you to read letters that are up close and far away. Then they’ll give you some eye drops to dilate (widen) your pupil and check for other eye problems.</p>

<p>After LASIK, most people see well enough to stop wearing their eyeglasses or contact lenses for most of their daily activities. Since everyone gets presbyopia as they age, and LASIK can’t fix presbyopia, most people will still need single vision glasses or contact lenses at some point.</p>

<p>LASIK can cause side effects, just like any surgery. Common side effects include:</p><ul><li>Dry eye</li><li>Seeing a glare or halo around bright lights</li><li>Double vision</li><li>Blurry vision</li><li>Sensitivity to light</li></ul><p>These side effects usually go away after a few months. Your eye doctor may give you eye drops or other medicines to help with these side effects. Rarely, these problems can be permanent.</p><p>Other risks of LASIK include:</p><ul><li>Infection</li><li>Problems with corneal healing</li><li>Vision loss, or seeing less clearly than you did before surgery</li></ul><p>If LASIK causes vision loss, you may need another surgery to fix it. Rarely, vision loss from LASIK may be permanent.</p><p>If you see clearly with eyeglasses or contacts, you may decide that the risks of LASIK outweigh the benefits. Talk with your eye doctor about the risks and benefits and decide together if surgery is right for you.</p>

<p>During an eye exam before the surgery, your eye doctor will use a scanner to make a detailed image of your cornea. This image will guide the laser during surgery.</p><p>Just before surgery, your doctor will put drops in your eye to make it numb. They may also give you a medicine to help you relax.</p><p>During the surgery, your doctor will cut a small flap in your cornea and fold it back. Then they’ll shine a laser into your eye. The laser will be programmed to change your cornea into the correct shape. Then they’ll put the corneal flap back in place.</p>

<p>Right after surgery, your eye might be irritated and your vision will be blurry, so you’ll need someone to give you a ride home from the doctor’s office.</p><p>Your eye doctor may give you medicine or special eye drops to help with any pain after the surgery. You may also need to wear a special patch over your eye for several nights, to protect it while you’re sleeping.</p><p>You’ll be able to see after surgery, but it takes 2 to 3 months for your eye to finish healing. Your vision will get clearer as your eye heals. Ask your doctor about when you can go back to your normal activities.</p>
