Abstract Details


To evaluate the clinical outcomes, complications and management of intrastromal corneal ring segment (ICRS) explantation in KKESH.


King Khaled Eye Specialist Hospital


Retrospective study (2007- 2017). Two groups were analyzed: Group 1: ICRS surgery done in KKESH (n: 41) and Group 2: surgery done elsewhere (n: 29). Causes of removal, POP outcomes and management were analyzed.


Causes of ICRS removal were visual disturbances (45-27%), ICRS extrusion (38-41%), corneal neovascularization (9-14%) and infection (6-16%). In Group 1: the elapsed time between implantation and explantation was 30 months. Refraction and keratometry were reversible when management was done with CL or glasses. Pre- implantation sphere of -8 can predict keratoplasty (p 0.02). Management was done with contact lens (45- 45%), observation (15-14%), glasses (15-23%) and keratoplasty (27-21%).


After explantation, most of the patients (60-68%) can be managed with glasses or CL. ICRS is a reversible surgery when the patients don't need PKP.
