Accommodating IOLs may very well transform the practice of cataract and refractive lens surgery.This is because accommodative IOLs can potentially provide unaided near visual acuity without the optical aberrations and image degradation that may accompany multifocal IOL implantation.
Yet, despite a mean accommodative amplitude of 1.08 ± 0.54 D (range 0-2.25), 86% of patients in this study required no correction for near vision during routine daily activities.
Not only will this enhance cataract surgery results, but it will also enable refractive surgeons to offer their patients a procedure that is unhindered by the restrictions of corneal refractive surgery and presbyopia.
Accommodating lenses can currently be classified into 3 categories: (1) single-optic, (2) dual-optic, (3) and deformable optic IOLs.
The Sarfarazi Elliptical Accommodating IOL and the Visiogen Synchrony are examples of dual-optic lenses.
Both of these IOLs utilize a positively powered biconvex front lens connected to a negatively powered concave-convex lens.
