Evaluating the Effect of Laser Vision Surgery, Phakic Intraocular Lens Implantation, Cataract Surgery, and Pupil Dilation on the Iris Recognition Scanner Function of Smartphone

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 outcomes

  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 outcomes

  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.
