摘 要：AIM:To evaluate the causes of phakic implantable collamer lens(ICL)exchange/explantation in patients with and without keratoconus(KC)at two tertiary hospitals in Riyadh,Saudi ***:A retrospective chart review of all patients who underwent ICL(model V4 c with central port)exchange/explantation was performed using the electronic medical record *** available preoperative and postoperative data were documented for each ***:Over 7 y,2283 ICL implantation procedures were performed;46 implants(2%)required exchange(21 implants)/explantation(25 implants),of which 14 cases(30.4%)were patients with *** for ICL exchange/explantation in non-KC group were vault measurement,cataract formation,increased intraocular pressure,inaccurate refraction,and patient dissatisfaction in 22(68.75%),4(12.5%),3(9.37%),2(6.25%),and 1(3.12%)case,*** most common indication for ICL exchange/explantation in the KC group was inaccurate vault sizing in 11 patients(78.57%),inaccurate refraction in 2 patients(14.28%),and patient dissatisfaction postoperatively in 1(7.14%)***:ICL implantation results in predictable refractive outcomes over the long term with exchange/explantation rates comparable to previous *** vault size is the most common cause of ICL exchange/explantation among patients with or without KC.
