How is farsightedness corrected?
To correct farsightedness, you must change the way the light rays bend when they enter your eye. Glasses, contact lenses, or refractive surgery can all be used to correct farsightedness.
Depending on the extent of your condition, you may need to wear your glasses or contact lenses at all times, or only when you need to see objects up close, like when reading or sewing. With farsightedness, your prescription is a positive number, such as +3.00. The higher the number, the stronger your lenses will be.
If wearing contacts or glasses isn't for you, refractive surgery can reduce or even eliminate your dependence on glasses or contact lenses. The most common procedures to correct farsightedness are:
- Photorefractive keratectomy (PRK): During a PRK, a laser is used to flatten the peripheral cornea so that light rays can focus closer to or even on the retina.
- Laser-assisted in situ keratomileusis (LASIK): During LASIK, a laser is used to make a flap through the top of the cornea. After the flap is lifted, the laser is used again to remove a small layer of the peripheral cornea. The flap is then dropped back into place. LASIK is the most commonly performed surgery to correct farsightedness.
