Brief Summary:
This study included patients who visit for refractive surgery (photorefractive keratectomy, photorefractive keratectomy with with corneal collagen cross linking, laser in situ keratomileusis, small incision lenticule extraction), phakic Intraocular Lens implantation (Implantable Collamer Lens, artiflex), and cataract surgery. Patients will be examined whether iris recognition scanner of smartphone works before and after surgery. In addition, before and after pupil dilation (5mm, 6mm, 7mm, 8mm), patients will be examined whether iris recognition scanner of smartphone works well.

Primary Outcome Measures :
  1. capability of iris recognition scanner [ Time Frame: 1 day before the surgery ]
    Patients will be examined whether iris recognition scanner of smartphone works 1 day before refractive surgery (photorefractive keratectomy, photorefractive keratectomy with corneal collagen cross linking, laser in situ keratomileusis, small incision lenticule extraction), phakic Intraocular Lens implantation (Implantable Collamer Lens, artiflex), and cataract surgery.

  2. capability of iris recognition scanner [ Time Frame: 1 week after the surgery ]
    Patients will be examined whether iris recognition scanner of smartphone works 1 week after refractive surgery (photorefractive keratectomy, photorefractive keratectomy with corneal collagen cross linking, laser in situ keratomileusis, small incision lenticule extraction), phakic Intraocular Lens implantation (Implantable Collamer Lens, artiflex), and cataract surgery.


Secondary Outcome Measures :
  1. pupil dilation [ Time Frame: 1 day before pupil dilation ]
    Patients will be examined whether iris recognition scanner of smartphone works well 1 day before pupil dilation.

  2. pupil dilation [ Time Frame: 1 week after the surgery ]
    Patients will be examined whether iris recognition scanner of smartphone works well 1 week after before pupil dilation.
