Today's Cataract Practice: Evolving technology to optimize patient’s outcomes I n an EyeWorld Asia-Pacific Corporate Symposium, support- ed by an educational grant from Johnson & Johnson on Saturday July 31, 2021, key oph- thalmologists presented on evolving technology in both the intraocular lens (IOL) world and advances in vision systems. A First in the Enhanced Monofocal Category Gerd Auffarth, MD, PhD, FEBO, Germany There have been many technological advance- ments with new IOL plat- forms, and the future is bright for cataract pa- tients. There has been much development in the past coming from a 3-piece lens to a 1-piece lens and from spherical to aspherical. Now, Gerd Auffarth, MD, PhD, FEBO, Germany says, “We have this TECNIS ® IOL platform that really increases the quality we expect from a good monofocal IOL.” In this new refractive lens design, the TECNIS Ey- hance TM IOL uses the lens design of the TECNIS 1-piece Platform, though visually it cannot be distin- guished from the TECNIS 1-piece IOL. The basic geometry is identical to all the other TECNIS 1-piece lenses, but there is an additional refractive de- sign without rings and a smooth defocus curve. These features provide an increase in depth of focus and other small advantages. Dr. Auffarth discussed how this new design has slightly enlarged the depth of focus made possible by a high order aspheric anterior surface that cre- ates a continuous power progression. This refrac- tive profile increases the power of the enhanced monofocal IOL continu- ously from the periphery to the center of the lens to extend the depth of focus. The higher order aspheric design of TECNIS Eyhance TM , at the same time, compensates corne- al spherical aberrations of -0.27 microns. The European “Quantum” clinical study on TECNIS Eyhance TM is a prospec- tive, multicenter, bilater- al, randomized, 6-month clinical trial that was pub- lished in the Journal of Cataract Refractive Sur- gery. This study included 140 patients who were bilaterally implanted with TECNIS Eyhance TM and compared to patients im- planted with the TECNIS 1-Piece IOL. At the 6-month visit, results were collected on 67 patients implanted with TECNIS Eyhance TM and 72 sub- jects implanted with the 1-Piece model. The results from this trial showed that Supported by an educational grant from Johnson & Johnson Vision “ TECNIS Eyhance is a new standard in monofocal lens with a larger ‘landing zone’ and enhanced depth of focus. ” Gerd Auffarth, MD, PhD, FEBO “ TECNIS Eyhance IOL provides statistically significant improvement in monofocular intermediate vision at 66cm. ” Gerd Auffarth, MD, PhD, FEBO
