Radial Keratotomy
The history of laser eye surgery goes back almost 100 years. Lans, a Dutch Ophthalmology professor, explained the basic principles of keratotomy in 1898. Sato, a doctor from
Radial keratotomy was put in practice by Dr. Fyodorov in
Dr. Leo Bores was the one to bring the technology to the
The discovery of certain limitations of radial keratotomy determined doctors to research alternative forms of eye surgery.
The Excimer Laser
The use of the Excimer laser was another important step in the history of laser eye surgery. Dr. Srinivasin was the first to discover its potential in interacting with biological tissue while working in the IBM research labs. Dr. Steven Trokel was the one to use it for the first time in reshaping corneal tissue. This laser device emits a cold beam that when interacting with corneal tissue, destroys carbon-carbon bonds between molecules, causing tissue ablation.
The excimer laser has been used in refractive surgery worldwide since 1987 and proved a high level of effectiveness and safety. Millions of patients suffering from various eye conditions have undergone this procedure.
Photorefractive Keratectomy (PRK)
Photorefractive keratectomy was also an important progress in the history of laser eye surgery. The first PRK surgery was held in 1988 in
Laser Assisted In-situ Keratomileusis (LASIK)
LASIK is a more recent discovery in the history of laser eye surgery. The surgeon uses a blade to cut a flap of the cornea and then a laser to remove tissue underneath the flap. Compared to PRK, this procedure allows the cornea to remain mostly intact. Therefore, the patients who have LASIK feel more comfortable and recover better and faster after surgery.
Surgeons have been performing LASIK for about 15 years now. The first surgery was performed in
In 1996, the FDA approved the laser treatment for myopia up to -6.00 diopters and in 1997; this procedure was approved for treating astigmatism up to -4.00 diopters.
Recent progress in the history of laser eye surgery includes advanced procedures to overcome the risks associated with laser treatment. Current technologies such as IntraLense use an extra laser instead of a blade and provide better safety and faster recovery. Other techniques allow an advanced level of accuracy and predictability, increasing the chance for a successful procedure.
