Abstract Details


To report the long-term clinical outcomes including efficacy and safety after intraocular collamer lens (ICL) implantation for myopia.


Department of Ophthalmology, Samsung Medical Center, Seoul, KoreaSungkyngwan University School of Medicine


Medical records of 110 eye of 60 patients underwent ICL implantation at Samsung Medical Center, followed up more than 7 yearsPre- and postoperative uncorrected and corrected distant visual acuity (UDVA and CDVA), spherical equivalent, endothelial density (ECD), and intraocular pressure (IOP) were analyzed.Postoperative vault and the rate of complications including cataract and glaucoma were also evaluated.


There was significant increase in CDVA after ICL implantation, compared with CDVA before ICL implantation (P<0.01, t-test). There was no significant change in CDVA after ICL implantation.There was significant decreasing in the mean endothelial cell count after 10 years postoperatively ,but there was no significant change in IOP during follow-upDuring 10 years of follow-up, fourteen eyes developed lens opacity at 10-year follow-up. 6 eyes had taken ICL removal and phacoemulsification. Phacoemulsification was performed in 6 eyes at 10 years after ICL implantation. The rate of lens opacity and phacoemulsification are closely related with decreased vault height.


The long-term clinical follow-up after ICL implantation indicates that ICL implantation has long-term stability and good refractive outcome. However, the risk of cataract increases along with the time after ICL implantation.
