title: Lens implant exchanges for incorrect power: results of an informal survey.
abstract: Despite the introduction of ultrasonic axial length measurements and a variety of intraocular lens implant prediction formulas, postoperative predicted errors greater than 2 diopters occur in approximately 5% to 10% of lens implantations, and occasional errors of 5 diopters to 7 diopters or greater are still encountered. An informal survey revealed successful lens implant exchanges for initial postoperative refractive errors of +4.37 to -14.00 diopters in eight eyes.
