An excimer laser, sometimes more correctly called an exciplex laser, is a form of ultraviolet laser which is commonly used in the production of microelectronic devices, semiconductor based integrated circuits or "chips", eye surgery, and micromachining.
Around 1980, Michael W. Berns, a professor of biology at the University of California, Irvine, founded an institute focusing on the then-new technology of lasers.After receiving a National Institutes of Health biotechnology grant, [3]: 328–331 he established a laboratory for laser microscopy, the Laser Microbeam Program (LAMP).

Rangaswamy Srinivasan and James Wynne filed a patent application on the ultraviolet excimer laser, in 1986, issued in 1988. [32] In 1989, Gholam A. Peyman was granted a US patent for using an excimer laser to modify corneal curvature. [33] It was, "A method and apparatus for modifying the curvature of a live cornea via use of an excimer laser.
By the end of the century, LCA-Vision was the third largest publicly held vision correction company in the United States, with 21 locations in the United States and two in Canada. [5] The company also continued to provide laser and minimally invasive surgery programs for hospitals and medical centers.
Treatment typically includes prescription of eye drops, medication, laser treatment or surgery. [1] [9] The goal of these treatments is to decrease eye pressure. [2] Glaucoma is a leading cause of blindness in African Americans, Hispanic Americans, [10] [11] and Asians. [12]
Following that, in 2022, a boat sent sonar pulses into Lake Oroville to map the underwater terrain. Engineers calculated that the reservoir had 3% less capacity — over 100,000 acre-feet — than ...
Laser surgery is a type of surgery that cuts tissue using a laser in contrast to using a scalpel. [ 1 ] Soft-tissue laser surgery is used in a variety of applications in humans ( general surgery , neurosurgery , ENT , dentistry , orthodontics , [ 2 ] and oral and maxillofacial surgery ) as well as veterinary [ 3 ] surgical fields.
The test maps a patient's cornea for raised areas and surface inconsistencies. LASEK and PRK are two different procedures. While both procedures interact with the epithelium atop the cornea, the PRK procedure removes this entirely, while LASEK brushes the material away for the procedure, before being placed back for healing after laser surgery.
