This chapter addresses the current status of phakic intraocular lens (PIOL)
surgery to correct refractive errors. Depending on the position, three types of PIOLs are
recognized: angle-supported anterior chamber, iris-fixated anterior chamber, and
posterior chamber PIOLs, which are usually fixated in the ciliary sulcus. The main
models of each type of PIOLs are introduced, also patient selection criteria, surgical
techniques and applications of anterior segment imaging techniques. Results of the
different models of PIOL are summarized, including specific PIOL or surgery related
complications. Implantation of PIOL is an effective, safe, predictable, and stable
procedure to correct moderate and high refractive errors. Complications are rare and
mostly related to the position and the type of the implant.
