History of LASIK Surgery
Laser vision correction was first approved by the U.S. FDA in October 1995 after more than 10 years of clinical trials, but the achievements that led up to this revolutionary treatment reach further into history. The success of LASIK surgery fuses the historical advances in both refractive eye surgery and laser technology.
Refraction refers to the way in which your eye bends light, permitting you to see. As early as the sixteenth century, Leonardo da Vinci speculated that vision impairments were due to the eye’s refractive errors.
Lasers have been used in ophthalmology since the 1970’s for conditions like glaucoma and retinal tears, but 1975 brought the advent of the excimer laser. This ultraviolet laser (on the cool end of the light spectrum) neither burns nor cuts but actually breaks the molecular bonds using light, allowing separation without heat. This type of gentle laser was found to be the perfect solution for refractive eye corrections.
The Evolution of LASIK
Excimer lasers were first used in Germany in 1985 and then the U.S. in a procedure called photorefractive keratectomy. PRK was approved by the FDA in 1995 and was one of the first successful procedures to correct vision using a laser; a refined version of the procedure still provides many patients who may otherwise be ineligible for LASIK surgery with clear vision.
Approved by the FDA in 1999, LASIK differs from PRK by creating a flap in the corneal epithelium to access and shape the corneal substance. Historically, LASIK procedures utilized a bladed microkeratome to create the epithelial flap. While some doctors still perform bladed LASIK, at LasikPlus, we consider our All-Laser LASIK approach a precise and comfortable LASIK option. Millions of people worldwide have opened their eyes to a clearer day thanks to LASIK treatment.
