title: [Light adjustable lens. New options for customized correction of presbyopia].
abstract: OBJECTIVE
  The aim of this study was a prospective evaluation of new algorithms for the treatment of presbyopia using a light-adjustable intraocular lens (LAL).
  
  
  METHODS
  A total of 15 patients scheduled for routine cataract surgery were included in the study. Following cataract removal a LAL (CalhounVision, Pasadena, CA) was implanted. At approximately 2 weeks after implantation the IOL was adjusted to correct any residual refractive error (sphere and cylinder) followed by the creation of a customized near add (CNA) that was based on the individual patient pupil size in one eye. The fellow eye was corrected for emmetropia. A final lock-in treatment was then performed.
  
  
  RESULTS
  There were no complications observed during the surgery or power adjustments. All patients demonstrated an improvement in near vision (0.97 ± 0.18) and distance vision (0.78 ± 0.18) with good intermediate vision (0.92 ± 0.12) months after the final lock-in.
  
  
  CONCLUSIONS
  This preliminary study showed that the creation of a CNA based on the individual patient's pupil size, provided patients with a good range of near, intermediate and distance vision following implantation of the LAL.
