Laser eye surgery
Laser Eye Surgery
Laser eye surgery (pronunciation: /ˈleɪzər aɪ ˈsɜːrʤəri/), also known as refractive surgery, is a type of eye surgery used to correct vision problems. The surgery works by reshaping the cornea, the clear front part of the eye, so that light entering the eye can be properly focused onto the retina.
Etymology
The term "laser eye surgery" is derived from the acronym LASER, which stands for "Light Amplification by Stimulated Emission of Radiation". The term "surgery" comes from the Greek "cheirourgia", meaning "hand work".
Types of Laser Eye Surgery
There are several types of laser eye surgery, including:
- LASIK (Laser-Assisted In Situ Keratomileusis)
- PRK (Photorefractive Keratectomy)
- LASEK (Laser-Assisted Sub-Epithelial Keratectomy)
- SMILE (Small Incision Lenticule Extraction)
Each type of surgery has its own benefits and risks, and the best option depends on the individual's specific vision problems and overall health.
Risks and Complications
Like all surgeries, laser eye surgery carries some risks. These can include:
- Dry eyes
- Glare, halos and double vision
- Undercorrections or overcorrections
- Astigmatism
- Corneal infection or corneal scarring
- Vision loss or changes
It's important for anyone considering laser eye surgery to discuss these risks with their ophthalmologist before making a decision.
