monofocal IOLs. It also de- livers a dysphotopsia profile similar to monofocal IOLs while reducing spherical ab- errations to nearly zero. As for image contrast, the TECNIS Eyhance IOL modulation transfer function (MTF) show similar MTF at distance in photopic con- ditions (3mm pupil) and at least 31% better MTF in mesopic conditions (5mm pupil) in comparison to oth- er monofocal IOLs. 1 In a prospective multi-center bilateral ran- domized study conducted in EMEA, TECNIS Eyhance IOL was compared to the TECNIS 1-Piece IOL ZCB00 (control). The objective was to evaluate the clinical performance of the TECNIS Eyhance IOL at 6-months. The results from this study showed that monocular distance vision with the TECNIS Eyhance IOL was comparable to that of the control IOL. Regarding contrast sensitivity, TECNIS Eyhance provided distance contrast sensitivity com- parable to the monofocal control IOL; the differences in contrast sensitivity be- tween the two IOLs were not statistically significant under both photopic and mesopic conditions. Similarly, the dysphotopsia profile of the TECNIS Eyhance was similar to that of the 1-piece con- Figure 4. The TECNIS Eyhance IOL delivers intermediate vision with monofocal optics for the first time with statistically significant improvement. trol IOL. However, for mon- ocular intermediate vision at 66 cm, TECNIS Eyhance showed statistically signifi- cant improvement. 2 With these results, it is promising to see what TECNIS Eyhance can achieve since it is able to deliver 20/20 BCDVA, offer significantly enhanced inter- mediate vision at 66cm, and has similar photic phenome- na to the control IOL. Regarding patient care and counseling with the TECNIS Eyhance, Dr. Findl said that he does not suggest ex- plaining the intricate details and expected outcomes of the TECNIS Eyhance IOL with his patients. “I think you should not try to [ex- plain]. If you tell the patient they will have better in- termediate vision, you are raising [their] expectations. Usually, I don’t tell the pa- tient about the lens. We just give the patient the lens. I don’t promise anything.” For patients around 55- 60 years old, they may have a life expectancy of about 90 years. These patients may develop one of the diseases that cause legal blindness later in life, such as AMD, DME or glaucoma. Thus it may not be ideal to implant a multifocal lens in their eyes. The procedure for exchanging lens in a patient after about 10 years is not ideal and not great for these diseases that may de- velop in the elderly. For the TECNIS Eyhance IOL, “I tell patients that you will need reading glasses for reading at great lengths of time, for small print, and for low light.” These are the three most important aspects for patients to be aware of post-operation, and typically patients will have no prob- lem adjusting with these constraints in their daily life.
