Study Details

Study Description

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.

    Outcome Measures

    Primary Outcome Measures

    1. capability of iris recognition scanner [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 [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 [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 [1 week after the surgery]

      Patients will be examined whether iris recognition scanner of smartphone works well 1 week after before pupil dilation.
