| Summary: | Currently, there are four general approaches to correct refractive errors: refractive corneal surgery, crystalline lens surgery, and implantation of an intraocular lens (IOL) in the anterior or posterior chamber. In any case, the main goal of refractive surgery is the smallest residual refractive error preserving vision quality with the same visual capacity. In this review, the current status of phakic intraocular lens (pIOL) surgery to correct refractíve errors is reviewed. Phakic IOL includes any lens located between the cornea and the anterior surface of the crystalline lens, which is left undisturbed inside the eye. The insertion of an implant in a phakic eye must be simple, precise, and reproducible and must produce successful optical results. In addition, implantation of a phakic IOL allows retention of accomodation and is reversible. Current IOL choice includes angle-fixated anterior chamber IOLs, iris-fixated anterior chamber IOLs, and the posterior chamber phakic IOL |
