Abstract
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.
