LASIK

March 16, 2019

Scientists have developed a new microscopy technique that could be used to improve laser vision correction, LASIK, and eliminate the "surgery" aspect of the procedure.

LASIK (laser-assisted in situ keratomileusis):  

  • Surgical procedures aimed at improving the focusing power of the eye are called refractive surgery. 

  • In LASIK surgery, precise and controlled removal of corneal tissue by a special laser reshapes the cornea changing its focusing power. 

  • When performed on both eyes, the entire procedure of LASIK surgery takes about 20 minutes and can rid patients of the need to wear glasses or contact lenses. 

Recent development: 

  • While LASIK has a very high success rate, virtually every procedure involves an element of guesswork, because doctors have no way to precisely measure the refractive properties of the eye. 

  • Now an assistant professor with the University of Maryland in the US developed a microscopy technique using Brillouin spectroscopy – a light-scattering technology – that could allow doctors to perform LASIK using precise measurements of how the eye focuses light, instead of approximations.
