System and Methods for Customizing an Intraocular Lens Using a Wavefront Aberrometer

A method of using an optical eye tracking instrument for dynamically measuring eye parameters, and for using a 3-D wavefront-customized phakic or pseudophakic intraocular lens (IOL) for correcting a person's vision, comprising the following steps, in the order presented:

• (1) measuring wavefront aberrations of a bare eye with a wavefront aberrometer;
• (2) implanting an uncorrected IOL into the eye;
• (3) determining a final position of the implanted, uncorrected IOL by optically measuring one or more fiducial marks located on the IOL;
• (4) designing a 3-D wavefront-customized correction profile for the implanted IOL;
• and
• (5) modifying in-vitro the un-corrected IOL with the 3-D wavefront-customized correction profile after the IOL has been implanted in the eye.

A method for correcting aberrations in an eye that uses a wavefront-customized phakic or pseudophakic intraocular lens (IOL), comprising the following steps, in the order listed:

• (1) designing and fabricating a phakic or pseudophakic intraocular lens that corrects for a base refraction of the eye;
• (2) implanting the intraocular lens in the eye;
• (3) measuring wavefront aberrations of the eye including the implanted lens;
• and
• (4) modifying in-vivo the aberrations of the implanted intraocular lens.

An optical instrument used for improving a person's vision, comprising a combined aberrometer, corneal topographer, and iris imaging camera, wherein the optical instrument comprises three paths:

• (b) a quarter wave plate (QWP);
• (c) a pair of beam splitters;
• (d) a pair of lenses, LENS1 and LENS2, configured as a telecentric teleobjective in the iris imaging path;
• (e) a telecentric stop (TSA) disposed in-between LENS1 and LENS2;
• and
• (f) an on-axis ins imaging camera;
• and
• wherein the wavefront sensor path #2 comprises:
• (i) a wavefront sensor camera;
• (ii) a collimated light source;
• (iii) a polarizing beam splitting cube;
• (iv) a third lens;
• and
• (v) a Range Limiting Aperture (RLA);
• and
• wherein the fixation target path #3 comprises a micro-video-display fixation target.

An optical instrument for tracking and treating an eye in-vivo comprising:

• (a) a femtosecond laser system for delivering low energy pulses to an eye;
• (b) an eye interface system for fixing the eye;
• and
• (c) a tracking system for determining and monitoring one or more positions of an IOL.
