A New Extended Depth of Focus Intraocular Lens Based on Spherical Aberration

CONCLUSIONS:</span><p>The new IOL with double spherical aberration in the central 3-mm zone offered good MTF over a wide dioptric interval, suggesting good visual acuity between 4 m and 50 cm. This extended depth of focus IOL with no diffractive rings is expected to produce lower unwanted optical phenomena than current multifocal IOLs.</p><p><b>[<i>J Refract Surg.</i> 2017;33(6):389 –394.]</b></p></div>
