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

Not Applicable

Completed

• Conditions: Cataract; Myopia; Myopic Astigmatism
• Interventions: Device: iris recognition scanner

• Registration Number: NCT02939001
• Lead Sponsor: Yonsei University

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.
