Intraoperative wavefront aberrometry to determine planar endpoint for the repositioning of vaulted accommodative IOLs

Abstract

Accommodative intraocular lenses (IOLs) are suitable options for patients desiring less dependence on spectacles after cataract surgery. Accommodative IOLs do not require diffractive optics and, therefore, might be used in a wider range of patients who have mild comorbidities or wish to avoid photopsia associated with diffractive IOLs. However, a small percentage of patients have experienced vault, or capsular contraction syndrome (CCS), due to fibroblastic metaplasia of lens epithelial cells. Early detection of CCS might be managed with Nd:YAG capsulotomy; however, accommodative IOLs with significant CCS have required viscodissection of the fibrosis and placement of a capsular tension ring. A challenge with this maneuver is using the operating microscope to determine whether the accommodative IOL has returned to planar position. This article describes a new technique using serial intraoperative wavefront aberrometry measurements of lenticular astigmatism during accommodative IOL repositioning to determine a planar endpoint in the reduction of vault.
