摘要:
Described is an accommodating intraocular lens with a bi-convex, bi-aspheric, smooth surfaced optic held inside an anterior annulus via tabs. A second larger diameter annulus is positioned posteriorly and connects via a sloped surface to where the annuluses are at a maximum separation when viewing NEAR objects and minimum separation in the FAR position. The sloped surface is cut into ribbons, tabs and/or other annuluses without pushing the surfaces into the capsule when implanted therefore, only the anterior and posterior annuluses have a force component against the capsule. The proximal edge of the anterior annulus is anterior to the apex of the anterior surface of the optic. The anterior capsule resting on the annulus leaves space for hydration of the capsule and reduces potential warpage of the optic. The annulus edge is designed to scrape posterior capsular opacification from the capsule.
