# Seeing Things Differently (DD-454)

> Laser vision correction aims to reduce dependence on glasses or contacts by reshaping the cornea. The main procedures are LASIK (laser-assisted in situ keratomileusis), PRK (photorefractive keratectomy) and SMILE (small incision lenticule extraction). They treat refractive errors such as myopia, hyperopia and astigmatism. The footage, credited to life_withmedical, shows an eye during laser surgery.

### Transcript

Did you know? Specs removal surgery, commonly referred to as laser vision correction surgery, is designed to reduce or eliminate dependence on eyeglasses or contact lenses. The most common procedures include LASIK or laser-assisted in situ keratomileusis, PRK or photorefractive keratectomy, and SMILE or small incision lenticule extraction. These surgeries reshape the cornea using advanced lasers to correct refractive errors such as myopia, hyperopia, or astigmatism. NOW YOU KNOW!
