摘　　要：AIM:To evaluate the visual outcomes of implantable collamer lenses(ICLs)and identify the possible risk factors for ICL axis misalignment,and consequently,repositioning,explanting,or exchanging at a specialized eye hospital in Saudi Arabia.METHODS:The medical records of 813 eyes with different refractive errors corrected with ICL implantation were identified and included in this single-arm retrospective cohort study.The following data were collected:demographic characteristics,primary diagnosis,preoperative refraction,anterior chamber depth(ACD),white-to-white(WTW)measurement,endothelial cell density(ECD),and axial length.Patients’satisfaction and complaints,and their postoperative refraction,vault depth,and axis alignment with the preoperative target,were reviewed during the postoperative period.Collectively,these data were correlated with symptomatic axis rotation and the need for repositioning,explantation,or exchange due to high or low ICL vaults.RESULTS:Of 813 eyes,27(3.32%),13(1.59%),and 11(1.35%)required ICL repositioning,ICL explantation only without exchange,and ICL explantation with the placement of a new ICL,respectively.The mean follow-up period was 37.5mo.The main cause of explanation or exchange was incorrect WTW measurement in seven(29.17%)eyes,followed by high vault in four(16.56%)eyes.ICL repositioning was required in 27(3.32%)eyes with considerable rotation.Only 2(0.24%)eyes developed cataracts that required ICL removal,and retinal complications were reported in 7(0.86%)eyes.Long-term glaucoma and corneal decompensation were not observed in this cohort.CONCLUSION:With a high safety profile and reversibility,ICL implantation is a good alternative to corneal-based refractive surgery in eyes unsuitable for laser vision correction.The rate of secondary procedures in our study was 6.26%.Old age is a risk factor for secondary surgical interventions in the repositioning group,whereas abnormal vault and toric ICL rotation in the explantation group necessitated subsequent surgical procedures.Overall,ICL
