curves, excellent contrast sensitivity, similar daytime contrast performance, and superior nighttime con- trast performance com- pared to competitor IOLs and monofocal IOLs. In one case report Dr. Auffarth presented, a 62 year-old healthy male with previously implant- ed refractive segmental multifocal IOL complained of difficulties adapting to bright and dark chang- es, extreme glare during car driving, large halos around light sources, and general extreme dyspho- topsias. Though his visual acuity was 20/20, he was unhappy due to the dys- photopsia he experienced. Dr. Auffarth conducted an IOL exchange and anterior vitrectomy in the right eye and IOL exchange with TECNIS Eyhance TM in the left eye. Two weeks after surgery, the patient had excellent visual acuity (un- corrected distance visual the TECNIS Eyhance TM IOL provided statistically significant improvement in monocular intermediate vision at 66 cm as well as statistically significant improvement in binocular intermediate vision. Al- though contrast sensitivity and the dysphotopsia pro- file was similar for patients in both groups, the Ey- hance IOL delivered better refractive outcomes than the 1-Piece IOL measured by the mean defocus curve. In the Asian population, a study conducted by Kang et al. (2021, Korean J Ophthalmol) showed a broader and wider defocus curve with significantly better visual outcomes in patients implanted with TECNIS Eyhance TM . In Dr. Auffarth’s personal experience with approx- imately 400 lenses im- planted in 308 patients, he found similar defocus acuity [UCDVA] binocu- lar 20/20). However, the patient was most satisfied with the improved visual quality (no halo or glare) from the lens exchange. In comparison to aspher- ic monofocal IOLs, Dr. Auffarth has seen pa- tients benefiting from the TECNIS Eyhance TM IOL with enhanced interme- diate visual acuity and a comparable profile of photic phenomena to other multifocal IOLs. “All the benefits from the hydrophobic material of the TECNIS IOL platform remain unchanged,” says Dr. Auffarth. Patients do not experience glisten- ing, thus no light scat- tering, and there is no risk of calcification due to hydrophilic materials. “What is more important than looking at this lens as a premium lens is that we have a new standard in monofocal lens with a larger ‘landing zone’ and enhanced depth of fo- cus,” concludes Dr. Auf- farth.

Premium IOL Innovation for Your Presbyopic Patients Han Bor Fam, MD , Singapore Current IOL innovation provides many solutions to all vision care patients, and Han Bor Fam, MD, Singapore says, “I have implanted multifocal IOLs for many years. As the years progress, we are moving away from good near vision to good inter- mediate vision. This is be- cause near vision tends to give more glare and halo with a shallow depth of field.” Dr. Fam shared with the audience the challeng- es and outcomes of new multifocals in his presen- tation. Regarding challenges with new multifocals, patients may want to participate in a variety of activities including reading, working on a computer, walking up stairs, and traveling, and this encompasses near, intermediate, and distant vision. “Most multifocals give us some near and some distant vision but at the expense of glares and halos. The worst case sce- nario is that there is also a loss of contrast,” says Dr. Fam. “Ideally, we want an IOL to give us good distant vision all the way to near vision. At the minimum, we need good distant vision and
