Provided are a method, a device, and a computer program for providing a guide for multifocal intraocular lens implantation on the basis of an analysis of a patient's corneal state. The method for providing a guide for multifocal intraocular lens implantation on the basis of an analysis of a patient's corneal state, which is performed by a computing device, comprises the steps of: obtaining ocular data generated by scanning a patient's ocular area; analyzing the obtained ocular data to determine the patient's corneal state; and providing a guide for multifocal intraocular lens implantation to be performed on the patient on the basis of the determined corneal state of the patient.
