Presbyopia Correction During Cataract Surgery with Multifocal Intraocular Lenses
Introduction: The first generations of multifocal intraocular lenses (MFIOLs) were designed to provide patients good distance and near vision, but intermediate was not satisfactory. Trifocal, a bifocal of low-add and quadrifocal MFIOLs were invented, offering possibility to correct vision for distance, near, and intermediate tasks. The novel IOL, extended range of vision (EROV), is covering mostly intermediate and distance vision, with lower level of photic phenomena.

Perspective Chapter: Strategies for Achieving Full-Range of Vision – Multifocal IOLs and Surgical Options for Correcting Residual Refractive Errors
Currently, cataract is considered one of the leading causes of visual impairment and blindness globally. Due to the development of surgical techniques and intraocular lenses (IOL) design, patient’s demands for complete spectacle independence have grown continuously. Today, the procedure of multifocal IOL implantation is an option for providing a full-range of vision. Although technology has advanced, there are still some drawbacks, such as lower optical quality postoperatively and postoperative residual refractive error, which also greatly reduces spectacle independence, visual quality, and patient satisfaction. Basic options for residual refractive error are the prescription of glasses or contact lenses, but in patients who require life without optical aids, corneal refractive surgery has proven to be a safe and predictable solution. Predominantly, laser-assisted in situ keratomileusis (LASIK) and photorefractive keratectomy (PRK) correction methods are applied, with an emphasis on Aberration-free excimer ablation profiles that do not include wavefront-guided treatments, given the uncertain methods of analyzing higher order aberrations (HOA) in patients with implanted multifocal IOLs.
