What is Laser Eye Surgery?
Laser eye surgery is also known as LASIK in medical fields. It refers to an operation by which laser is used underneath the corneal flap to correct refractive errors. It can also be used to improve vision or even eliminate the need for glasses and contact lenses. This medical procedure was first conducted in Greece at around 1991.
How It Works
Laser eye surgery makes use of excimer laser to remove the thin layer on the corneal tissue of the eye. This, therefore, gives the eye a new shape so that light rays reflect correctly on the retina in order to improve eyesight. The cost of laser eye surgery is approximately $2,246 per eye. This outpatient procedure takes about 15 to 20 minutes to be completed.
Types of Laser Eye Surgery
Notably, there are different types of laser technologies that can be used to improve eyesight. While the underlying principle of operation is similar, different manufacturers have different application protocols. The type of laser technology used on a patient’s eye depends on a number of factors including the extent of the damage on cornea and intended results of the surgery. Notable types are LASIK, PRK, LASEK, and PRELEX.
Wrapping it up
Laser eye surgery is a game changer in the medical field that was previously marred with uncertainty. With this technology, treatments on the cornea are now easy, straightforward and indeed more affordable. Additionally, laser surgery procedures are relatively accurate as compared to the traditional operation procedures that would leave patients bedridden for over a month in the course of recovery.
