Implantable collamer lens (ICL)


  • Implantable collamer lenses are a type of posterior chamber phakic intraocular lens (pIOL).
  • Advantages over corneal refractive surgery also include quicker recovery and reversibility.
  • Posterior chamber pIOL provide a more cosmetically appealing alternative to anterior chamber (AC) pIOL because they are less visible externally and create less risk of endothelial cell loss (ECL) as they are placed further away from the cornea.
  • They are a safer alternative to refractive lens exchange which carries a risk of retinal detachment and loss of accommodation.
  • pIOL are usually used for high degrees of refractive error or when corneal refractive surgery is contraindicated.
