LASIK eye surgery is a refractive procedure that was once a high risk option, but is now one of the most common ways to correct vision issues as cataract. The process of LASIK eye surgery has come quite a long way since the idea first came to vision pioneers many years ago.

History of Refractive Surgery

A Netherlands ophthalmologist, Lendeer Jans Lans was the first person to suggest a use for refractive eye surgery back in 1896. Lans’ theory called for the use of penetrating cuts into the eye’s cornea in an attempt to correct astigmatism.

In 1963, when Jose Barraquer developed the next major breakthrough in refractive eye surgery. He developed a process called keratomileusis, which involved the removal of the corneal layer, freezing the removed layer, reshaping the it to the desired size for vision correction of myopia and hyperopia, and re-insert the layer back into the eyeball. The procedure was hit and miss during it’s use, until further development of the process was mastered.

In 1983, R. Srinivasan along with Columbia University scientist Stephen Trokel performed the first procedure that didn’t require the removal of the corneal layer, called Photorefractive Keratectomy. Upon receiving a patent for the procedure in the United States in 1989, this earlier procedure is considered to be the very first LASIK surgery ever conducted.

Different Refractive Surgical Techniques

There are many different types of techniques and procedures used to correct vision maladies such as cataract, astigmatism, nearsightedness and several others. Some of the procedures used to correct these common vision conditions include flap procedures, surface procedures, and corneal incision procedures.

Flap Procedures

There are to primary types of flap procedures used to treat common vision issues such as cataract. The first is known as an ALK, which stands for automated lamellar keratoplasty. This type of procedure uses a mircokeratome, and involves cutting a flap into the corneal tissue of the eye, repairing of the affected tissues are performed, and the flap is replaced.

The second common procedure that is used is called Laser assisted in-situ keratomileusis, better known as LASIK. LASIK procedures involve utilizing an instrument called a femtosecond laser that cuts a flap into the corneal tissue using the excimer laser. Such as the ALK, the flap is replaced upon completion of the procedure.

Surface Procedures

There are many more types of surface procedures, but basically the difference between flap and surface procedures using the excimer laser is how the skin layer of the affected area is handled. Some of the surface procedures include: EPI- LASIK, photorefractive keratectomy, customized transepithelial, no-touch procedures and laser assisted sub-epithelium keratomileusis,. These are generally outpatient procedures for the treatment of vision issues such as cataract.
