Eye surgery system and method of inserting an intraocular lens

An eye surgery system, comprising:

• a user interface;
• a measuring system configured to determine at least the following values of an eye:
• a value representing a curvature of a cornea of the eye,
• a value representing a distance between a corneal apex of the eye and a retina of the eye, and
• a value representing a distance between the corneal apex of the eye and a crystalline lens of the eye, and
• a value representing a distance between the corneal apex of the eye and the intraocular lens;
• a first computing module configured to determine a first value representing a property of an intraocular lens, wherein the first value is determined based on at least the following values:
• the value representing the curvature of a cornea of the eye,
• the value representing the distance between the corneal apex of the eye and the retina of the eye, and
• the value representing the distance between the corneal apex of the eye and the crystalline lens of the eye;
• a second computing module configured to determine a second value representing a postoperative visual defect of the eye, wherein the second value is determined based on a simulation performed on an eye model, and wherein the eye model includes at least the following parameters:
• a parameter representing a curvature of a cornea of the eye,
• a parameter representing a distance between a corneal apex of the eye and a retina of the eye, and
• a parameter representing a distance between the corneal apex of the eye and a crystalline lens of the eye,
• a parameter representing a distance between the corneal apex of the eye and the intraocular lens of the eye;
• a parameter representing a refractive power of the intraocular lens;
• a controller configured
• to receive at least the following preoperative values determined by the measuring system:
• the value representing the curvature of the cornea of the eye,
• the value representing the distance between the corneal apex of the eye and the retina of the eye, and
• the value representing the distance between the corneal apex of the eye and the crystalline lens of the eye;
• to trigger the first computing module to determine the first value representing the property of the intraocular lens, based on the determined preoperative values;
• to trigger the user interface to display the first value representing the property of the intraocular lens;
• to trigger the measuring system to determine at least the following intraoperative values:
• the value representing the distance between the corneal apex of the eye and the intraocular lens;
• to trigger the second computing module to determine the second value representing the postoperative visual defect of the eye, wherein:
• the preoperative value representing the curvature of the cornea of the eye is assigned to the parameter of the eye model representing the curvature of the cornea of the eye,
• the preoperative value representing the distance between the corneal apex of the eye and the retina of the eye is assigned to the parameter representing the distance between the corneal apex of the eye and the retina of the eye, and
• the intraoperative value representing the distance between the corneal apex of the eye and the intraocular lens is assigned to the parameter of the eye model representing the distance between the corneal apex of the eye and the intraocular lens;
• to trigger the user interface to display the second value representing the postoperative deficiency of the eye.

A method of inserting an intraocular lens into an eye, the method comprising:

• determining preoperative values of an eye;
• selecting an intraocular lens based on the preoperative values;
• inserting the intraocular lens into the eye;
• determining intraoperative values of the eye;
• providing an eye model, wherein the eye model includes plural parameters;
• determining the second value representing a postoperative visual defect of the eye using the eye model, wherein the preoperative values of the eye are assigned to a first subset of the plural parameters of the eye model and wherein the intraoperative values of the eye are assigned to a second subset of the plural parameters of the eye model;
• and
• correcting the position and/or the orientation of the inserted intraocular lens or inserting a different intraocular lens based on the value representing the postoperative visual defect of the eye.
