Basic forms of eye surgery can be tracked back to the late 1890s and early 1900s. By the 1970s, doctors were researching methods on how to utilize lasers to help advance eye surgery. The initial form was patented by Dr. Steven Trokel in the 1980s. This method utilized the Excimer laser, and the first eye surgery was performed in 1987. The Excimer laser was used to correct the cornea. The techniques and methods of this particular type of surgery have continued to evolve over the following decades, and eventually it was determined that the Excimer laser was better utilized for ophthalmic refractive surgery.
Decades after the first laser eye surgery was completed, techniques continue to advance. Photo refractive keratectomy (PRK) was invented in the early 1980s. This method utilizes the Excimer laser to remove bits of tissue from around a patient’s cornea. In 1990, two Italian doctors, Dr. Lucio Buratto and Dr. LoannisPallikaris, developed the technique known as LASIK eye surgery. This technique is based on two previous utilized techniques, PRK and Keratomileusis. Keratomileusis is the reshaping of a patient’s cornea. PRK is typically a better option over LASIK for patients with larger pupils or thin corneas. To find the best local eye doctor for more information consult our directory.
The LASIK technique works because it reshapes the cornea to fix refractory errors that the eye is experiencing. Different types of refractive errors are myopia, hyperopia and astigmatism. Helping to further advance the LASIK technique, in 1990, Dr. Jose Barraquer of Columbia developed the Microkeratome device. This device, in along with the Excimer laser, cuts flaps in the cornea which alters the cornea’s shape, and therefore the patient’s vision. Most variations of LASIK on the market are based on the different types of laser ablations. Laser ablation is the method which the laser reshapes the cornea. These ablations include conventional laser eye surgery treatments, wavefront-guided treatments, and wavefront-optimized treatments.
There are other refractive eye surgeries available other than LASIK. These surgeries include advance surface ablation, phakic intraocular lenses, conductive keratolasty and intracorneal ring segments. The most effective treatments for patients experiencing typical near or farsightedness is LASIK. Phakic intraocular lenses are best for patients with extreme myopia and are not candidates for LASIK or advance surface ablation. Conductive keratolasty is the best option for patients with hyperopia or presbyopia. Finally, intracorneal ring segments is best for patients with low myopia and keratoconus.
If you find yourself in need of some type of eye surgery, make sure to talk to an eye doctor in your area. They will help you determine what is best for you, as well as review any risks associated with the procedure. Before proceeding with any surgery make sure you are comfortable with the doctor performing the procedure.
