[Research advances on size selection and vault prediction of posterior chamber phakic intraocular lens].

Posterior chamber phakic intraocular lens (pIOL) implantation has been widely adopted for the correction of refractive errors. Among pIOLs, the Implantable Collamer Lens is the most common choice. The selection of the appropriate pIOL size and achieving the desired postoperative vault to minimize complications has consistently been a focal point in academic research. With the advancement of ophthalmic biometric measurement technology and the application of artificial intelligence in the field of medicine, numerous new technologies and methods for pIOL size selection and vault prediction have emerged in recent years. This paper provides a comprehensive review on the topic of how to choose the pIOL size and predict the vault.
