Abstract
Provided are a method for predicting a Vault after phakic intraocular lens and an electronic device. After a thickness of a to-be-corrected crystalline lens, and a horizontal sulcus-to-sulcus value and a vertical sulcus-to-sulcus value corresponding to the to-be-corrected crystalline lens are obtained, a diameter ICL Size and an axial position ICL Ax of a preset ICL lens are collected, an effective sulcus-to-sulcus value, a lens thickness influence factor LTF, a Vault chord height h and the Vault are sequentially calculated according to the obtained data, and whether the diameter ICL Size and the axial position ICL Ax of the currently adopted ICL lens meet the Vault requirement or not is judged according to the Vault. The predicting accuracy and precision of a lens position after ICL lens implantation is reduced, postoperative complications are reduced, and the convenience of clinical operation and the safety of ICL operation are improved.
