The technology that we surgeons employ for the preoperative workup plays an important role in helping us achieve the best visual results. Nonetheless, a significant number of patients do not achieve a plano result after cataract surgery. Unfortunately, we still do not know if our IOL calculations, limbal relaxing incisions (LRIs), or placement of a toric IOL is accurate until we see patients postoperatively. IOL power calculations are especially difficult in eyes that have undergone RK, LASIK, or PRK. Moreover, we work under the assumption that every cataract incision will have the same effect on the eye’s cylinder. What has been missing is a tool that allows us to determine intraoperatively whether we have achieved our refractive goal.
The introduction of the ORange intraoperative wavefront aberrometer (WaveTec Vision, Aliso Viejo, CA) allows us to measure the impact of the cataract surgical procedure and to determine if the result is close to the intended postoperative correction. This article reviews the multiple applications of the aberrometer as well as the initial clinical experience of users including myself. ..Download
