Scientists have developed a new microscopy technique that could one day be used to improve laser vision correction, LASIK, and eliminate the &quot;surgery&quot; aspect of the procedure.<br />”<br />”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. <br />”<br />”While LASIK has a very high success rate, virtually every procedure involves an element of guesswork, according to the study published in the journal Physical Review Letters.<br />” &nbsp;<br />”This is because doctors have no way to precisely measure the refractive properties of the eye. Instead, they rely heavily on approximations that correlate with the patient's vision acuity — how close to 20/20 he or she can see without the aid of glasses or contacts.<br />” &nbsp;<br />”<span style="color: #222222;">Giuliano Scarcelli, an assistant professor with the University of Maryland in the US developed a microscopy technique that could allow doctors to perform LASIK using precise measurements of how the eye focuses light, instead of approximations.</span><br />
