How to Perform Laser Eye Surgery
Ophthalmologists have been reshaping the cornea for over fifty years. The two most common types of laser eye surgery today are Laser Assisted in-Situ Keratomileusis (LASIK) and Photorefractive Keratecomy (PRK). How was the concept of laser eye surgery developed and continue to develop today? How is laser eye surgery performed?
The idea of being able to reshape the cornea and improve vision has been developing over the last one hundred years. During the 1930’s Japanese and European doctors recognized the possibility of being able to cut onto the cornea and realized the potential for correcting the visually impaired (The History of Lasik Surgery). The practicality of being able to correct vision by lasers and surgical tools was introduced in 1970 by Dr. Fyodorove of Russia (Information About Laser Eye Surgery). Dr. Fyodorove was treating a young patient who had fallen off of his bike. His glasses had broken and a glass particle had cut into his eye. Instead of the glass injuring the patient it shaved off the outermost surface of the eye. This corrected the hyperopia of the young patient. Dr. Fyodorove documented and conducted further research of the incident. Due to better funding and advanced medical equipment in 1978 American doctors realized the potential accuracy a laser could introduce to the procedure. Up until this date more than 2 million surgeries around the world had been performed with no more than surgical tools and anastesthetic drops (The History of Lasik Surgery). By November 1994 more than 1,000,000 laser eye surgeries had been performed in 40 different countries.
Before surgery the doctor will determine if the patient’s eyes are fit to undergo the operation. The doctor will generally not perform the surgery if the patient has a very high prescription because of the excessive amount of corneal tissue that would have to be removed from the surface of the eye. Thin corneas also cause a...
