Retrospective Comparison of Visual Outcomes After KAMRA Corneal Inlay Implantation With Simultaneous PRK or LASIK.

Purpose: To report a retrospective study of simultaneous LASIK versus photorefractive keratectomy (PRK) with accompanying small-aperture cornea inlay implantation (KAMRA; AcuFocus, Inc., Irvine, CA) in treating presbyopia.

Methods: Simultaneous LASIK/inlay and simultaneous PRK/inlay was performed on 79 and 47 patients, respectively.

Corneal Hydrops Secondary to Intrastromal Corneal Ring Intrusion into the Anterior Chamber 7 Years after Implantation: A Case Report.

Introduction: This report describes the first known case of late-onset intrusion of an intrastromal ring segment into the anterior chamber due to posterior migration of a ring segment. To our knowledge, intrastromal ring segment penetration has only been shown to occur in the intraoperative or immediate postoperative period. We postulate that the perforation in this case is due to progressive thinning of the cornea, possibly in combination with habitual eye rubbing.
