Developments in Accommodating Intraocular Lenses

Technical progress in cataract surgery has decreased the incidence of severe complications in this type of surgery. The introduction of micro\udincision cataract surgery (MICS) (sub- 2.0 mm incision) allow the surgeon to achieve better postoperative control of astigmatism and higherorder\udaberration (HOAs) with minimum induction of both. It is believed that multifocal lenses provide very successful results, however, there\udare limitations to these. Implantation of accommodating intraocular lenses (IOLs) is an option to treat presbyopia. The IOLs work by using\udthe continued functionality of the ciliary muscle after cataract removal. Accommodating IOLs were designed to avoid the optical side effects\udof multifocal IOLs. Two main design concepts exist. First, axial shift concepts rely on anterior axial movement of one or two optics creating\udaccommodative ability. Second, curvature change designs are designed to provide significant amplitudes of accommodation with little physical\uddisplacement. Accommodative IOLs to correct astigmatism and HOAs in the future are needed. (Turk J Ophthalmol 2012; 42: 288-93
