Primary Outcome Measures:
  • Foreign body sensation [ Time Frame: 1 month postoperatively ]
    Foreign body sensation will be assessed by a direct 5-scale, Likert type question that will be addressed to the participants at the 30th postoperative day

Secondary Outcome Measures:
  • Ocular Redness [ Time Frame: 7 days postoperatively ]
    Ocular redness will be assessed by means of a validated photographic chart

  • Corneal Sensitivity [ Time Frame: 1 month postoperatively ]
    Corneal Sensitivity will be assessed by Cochet-Bonnet esthesiometer at the 7th and 30th postoperative day

Enrollment: 80
Study Start Date: January 2015
