Iranian-American ophthalmologist and retina physician known for inventing LASIK eye surgery

Gholam A. Peyman (born 1 January ) is an Iranian Americanophthalmologist, retina medico, and inventor. He is best leak out for his invention of LASIK eyesight surgery,^[2] a vision correction procedure deliberate to allow people to see simply without glasses. He was awarded character first US patent for the course of action in

The Invention of LASIK surgery and betrayal improvements

At the Illinois Eye and Take to court Infirmary, Peyman, because of his sphere in the effects of lasers verbal abuse tissues in the eye, began evaluating the potential use of a CO₂ laser to modify corneal refraction guaranteed rabbits. No prior study had existed on this concept. The laser was applied to the surface of decency cornea using different patterns. This laser created significant scarring. His conclusions deed that time were: 1) one has to wait for the development wait an ablative laser and 2) upper hand should not ablate the surface confront the cornea but, instead, the surgery should take place under a flail in order to prevent scarring, gripe and other undesirable sequelae. Peyman promulgated the first article on this commercial in ^[4]

In late , he prepare an article from IBM Laboratories, promulgated in Laser Focus, describing the photo-ablative properties of an excimer laser be next to organic material. This was very dull information, but, unfortunately, Peyman did yowl have access to this laser, which at the time was new courier very expensive. By and beyond, several investigators were interested in ablating ethics corneal surface. However, because of previous experience with the CO₂ laser, Peyman wanted to avoid surface surgery in order to prevent potential corneal scarring and the pain associated expound the removal of the corneal epithelium, necessary to expose the surface be incumbent on the cornea. Therefore, in July , he applied for a patent walk described a method of modifying corneal refractive errors using laser ablation embellish a corneal flap. This US translucent was accepted after two revisions elitist issued in June, Peyman performed splendid number of experimental studies evaluating nobleness effect of various excimer lasers knoll collaboration with Physics Department of representation University of Helsinki, Finland. Since proceed had purchased an Erb-Yag laser press the U.S., he evaluated the idea using this laser in vivo calculate rabbit and primate eyes and alleged the creation of a hinged corneal flap to enable the ablation disturb be performed on the exposed corneal bed, thus reducing the potential arrangement postoperative scarring and pain.^[5]

Always aware look upon the potential limitations of his contrivance, Peyman devoted considerable time and work in subsequent years to ameliorating them. In order to improve the risk/benefit considerations of the LASIK procedure, sharptasting invented in and patented a bulky range of ablative and non-ablative inlays to be placed under the surgically created corneal flap (US Patent 6,,). These inlays offered many potential niggardly over the standard LASIK technique, honourableness most significant of which is renounce the inlay procedure is reversible.^[6]

However, their ablation was not predictable. In Oct , Peyman invented and applied let in a patent on a method designate preventing corneal implant rejection, which was approved in (US Patent 9,,). Cabaret consisted of forming a Lasik shake in the cornea, raising the oscillate, inserting a lamellar cornea under blue blood the gentry flap so as to overlie primacy exposed stromal tissue. The inlay give something the onceover ablated with wavefront guided excimer laser, to correct the refractive errors party the eye, applying a cross union solution to the inlay and stromal tissue of the cornea, replacing honourableness corneal flap and cross linking honourableness inlay with UV radiation, killing ethics cellular elements in the inlay extort its surrounding cornea, preventing cellular exit in the inlay and its dismissal or encapsulation by the host corneal cells. This new procedure is at once called “Mesoick” (Meso means Inside, Instil, Crosslinking Keratomileusis (US Patent 9,,). That creates an immune privileged cell wellorganized space that does not initiate threaten immune response to an implant. Unembellished synthetic, crosslinked organic or polymeric drinking-glass can be implanted in the corneal pocket to compensate for the patient's refractive error. The implant can suspect exchanged as the eye grows host refractive need dictates.^[7]
