title: Advances in Refractive Surgery.
abstract: OBJECTIVE
  The objective of this study was to review advances in the field of refractive surgery as reported in the peer-reviewed literature over the previous year.
  
  
  METHODS
  This was a literature review.
  
  
  METHODS
  We conducted a PubMed search for terms related to refractive surgery and reviewed prominent international ophthalmic journals published from May 2012 through April 2013. All pertinent articles were reviewed, and selected articles with the greatest relevance were included.
  
  
  RESULTS
  Many studies over the previous year have highlighted progress in the field of refractive surgery; topics included keratoconus screening, photorefractive keratectomy and laser in situ keratomileusis, corneal cross-linking, small-incision lenticule extraction, phakic intraocular lenses, corneal inlays, presbyopic corneal treatments, and femtosecond laser-assisted astigmatic keratotomy.
  
  
  CONCLUSIONS
  The field of refractive surgery continues to provide exciting developments. Improvements in established procedures and promising new surgical options make the current climate an appealing one for refractive surgeons and patients.
