LASIK is a laser eye surgery that corrects vision issues and frees you from wearing glasses or contacts. It involves using custom lasers to reshape the cornea, improving how light is focused on the retina. Surgeons utilize this procedure to address conditions such as nearsightedness, farsightedness, and astigmatism. Here are some vision issues addressed with laser eye surgery:
1. Nearsightedness
Nearsightedness causes distant objects to appear blurry while close-up objects remain clear. The condition occurs when the cornea becomes too curved or the eye itself is longer than normal. This causes light rays to focus in front of the retina instead of directly on it. During LASIK eye surgery, a laser flattens the central cornea to reduce its focusing power. Light rays then come to a focal point on the retina, producing clearer distance vision.
2. Farsightedness
Farsightedness makes nearby objects blurry while distant objects remain clear. Laser surgery can correct this by steepening the central curvature of the cornea, which enhances its focusing power. This improvement allows for clearer vision at near, intermediate, and distant ranges. By reshaping the cornea, the surgery helps direct light more accurately onto the retina, resulting in sharper vision.
3. Astigmatism
Astigmatism results in blurred or distorted vision at all distances. It occurs when the cornea is oval-shaped instead of spherical, causing light to focus on two points rather than one on the retina. The laser reshapes the meridians of an irregular cornea during surgery. This is to achieve a clearer, more symmetrical form. Before correcting any existing astigmatism, surgeons measure the precise degree and axis to guide treatment planning. This step helps make sure the treatment is tailored precisely to each patient’s level of astigmatism, which can vary from mild to severe.
4. Presbyopia
Presbyopia results in blurry near vision as the eye’s focusing power decreases with age. By steepening the central cornea, laser surgery can restore some of this lost ability to change focus. Laser eye surgery helps presbyopic patients see both distance and near by creating monovision. Using blended vision techniques, surgeons customize the treatment by creating a slight prescription difference between your two eyes. One eye is set for clear distance vision, while the second eye compensates for close-up vision.
5. Combined Vision Issues
Some patients may have combined vision issues, such as nearsightedness with astigmatism or mixed astigmatism. Mixed astigmatism occurs when one part of the eye is nearsighted while the other is farsighted. This can lead to both near and distance vision problems. Custom laser surgery can treat several vision problems at once, allowing patients to achieve clear, unaided eyesight across a full range of distances.
Address Vision Issues With Laser Eye Surgery
Laser eye surgery uses detailed mapping to guide precise treatment. This mapping highlights areas of the cornea that need correction and reshaping. By sculpting the cornea, the procedure directly addresses the root cause of blurry vision. Advanced technology customizes the laser treatment, enhancing the eye’s ability to focus light clearly.
