Abstract — We describe an optics‐based technique for non‐contact measurements of the thickness parameters of intraocular lenses (IOLs). The technique is based on time‐domain low‐coherence interferometry (LCI) using a beam of light directed to a point on the measurement surface. We show how this technique can be used to measure the difference in thickness of the opposite haptics, and to measure the center thickness of the IOLs located on a mandrel or suspended in a solution.
