There has been an evolution in surgical techniques, expected outcomes, and patient expectations for cataract surgery in the past 15 years. Nevertheless, issues such as previous corneal refractive surgery,¹ contact lens use before corneal curvature measurement,² extremely high myopia or hyperopia,³ and false assumptions in the use of ultrasonic axial length measurements⁴ can lead to unexpected postoperative refractive results. In 2003, incorrect lens power was the most common cause of lens explantation in both 1-piece and 3-piece hydrophobic acrylic lenses.⁵

A case can then be made for the development of an adjustable intraocular lens (IOL) that would allow modification of any unexpected postoperative refractive results in adults. Several designs of such a lens have been described, but there are essentially 2 types.⁶ One type relies on actual refractive power change of the IOL, eg, the light adjustable lens⁷ or the Werblin lens system.⁸ The second type . . .
