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.

Conditions

Cataract; Myopia; Myopic Astigmatism

Outcome Measures

Primary Outcomes (2)

• capability of iris recognition scanner

  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.

  1 day before the surgery

• capability of iris recognition scanner

  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.

  1 week after the surgery

Secondary Outcomes (2)

• pupil dilation

  1 day before pupil dilation

• pupil dilation

  1 week after the surgery
