Abstract
The invention relates to the field of ophthalmic systems and procedures. In particular, the invention relates to the determination of the post-operative position of an intraocular lens (termed “IOL”) in an eye of a patient undergoing lens replacement surgery, which involves determining the position of the existing crystalline lens in the pre-operative eye of the patient and using that information and a single numerical constant to predict the post-operative intraocular lens position. Related methods, and computer programs for performing the methods of the invention, are also disclosed.

A method for predicting the post-operative position of a replacement intraocular lens in an eye of a patient, the method comprising the steps of:
- (i) measuring the position of the existing crystalline lens in the pre-operative eye of the patient;
- (ii) measuring the thickness of the crystalline lens in the pre-operative eye of the patient;
- and
- (iii) calculating the post-operative position of the intraocular lens relative to the position of the crystalline lens in the pre-operative eye of the patient, as a proportion of the thickness of the crystalline lens in the pre-operative eye of the patient,
- wherein the proportion is defined by a single numerical constant (C) which is determined by the intraocular lens type.
