Categories of advanced-technology IOLs: overview.


Cataract patients have long benefited from the improvement in vision that the intraocular lenses (IOL) provide since they were first introduced by Dr Harold Ridley in 1949. However, significant problems such as dense capsular fibrosis and lens dislocation arose with the initial IOLs, necessitating further advances in their design. Although the first IOL was approved by the US Food and Drug Administration in 1981, it is the developments within the past decade that have presented physicians and their patients with the most options and successful outcomes to date. Recent lens technology now allows the patient to choose a lens that can correct spherical error, astigmatism, presbyopia, and higher order aberrations. Although exciting, this advancement in lens technology makes the decisions surrounding lens selection and cataract surgery considerably more complex for both the patient and physician. Physicians must bear in mind that conditions such as presbyopia, astigmatism, and corneal aberration are likely not part of a patient’s vernacular. Therefore, careful explanation, confirmation of patient’s understanding of these terms, along with confirmation of any other pertinent ocular conditions must be made before final lens selections and surgical decisions are made. Furthermore, physicians must ensure preoperatively that patients have realistic expectations regarding their surgical outcomes in terms of likely postoperative vision, lens limitations, and potential complications. Thus, the importance of patient education and understanding surrounding IOLs and cataract surgery are imperative in maximizing patient satisfaction. For these reasons, the preoperative discussion is lengthy and involved. It is the goal of this article to clearly and systematically delineate the advantages and disadvantages of the various types of IOLs currently
