LASIK surgical treatment deals with vision problems because of refractive errors.
Refractive errors take place when light rays cannot take a trip through the cornea as well as the lens to send signals from the retina to the brain. This causes the image formed on the retina to be indistinct, causing blurred vision. LASIK Eye surgery [ศัลยกรรมตา, which is the term in Thai] procedure can permanently transform the form of the cornea so that light rays can focus on the retina.
The LASIK treatment treats:
- Farsightedness
- Nearsightedness
- Astigmatism
It is important to note that LASIK may not have the ability to deal with presbyopia, a refraction error as a result of older age that causes several to put on reading glasses to remedy.
Prior to proceeding with the LASIK surgical procedure, a doctor will review a person’s eye health, as well as determine the cornea, students, as well as refractive mistakes. Individuals that wear contact lenses might require to switch to glasses for as much as several weeks before the medical professional takes these dimensions. This enables the cornea to go back to its natural shape as well as minimizes dimension errors.
Throughout the procedure, a cosmetic surgeon will cut a flap into the cornea, exposing the stroma, the center area of the cornea. They will then utilize a pulsing laser to vaporize components of the stroma before replacing the flap.
Surgeons embrace either strategy for developing the flap in the cornea. Conventional LASIK utilizes a mechanical blade, while all-laser LASIK treatments utilize a tool called a laser keratome. A 2015 study found no statistically considerable distinction in the result of either technique, as well as both, are risk-free and efficient.
The procedure takes no more than 30 minutes, as well as people are awake throughout the surgery. Prior to the procedure, a medical care specialist will numb a person’s eyes and hold their eyelids open with a speculum.
