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

Yonsei University25 enrolled

Overview

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.

Outcomes

Primary Outcomes

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.

Time frame: 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.

Time frame: 1 week after the surgery

Secondary Outcomes

pupil dilation

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

Time frame: 1 day before pupil dilation
