Digital access to medical information has produced What presbyopia-mitigating options and approaches a well-informed patient generation with high expectations exist in the United States, and what are the for their health and treatment options. Patients today have limitations? these higher expectations because they are often paying Dr. Braga-Mele: We’ve been able to offer presbyopia- out-of-pocket costs for health care, prompting patients correcting intraocular lenses (PCIOLs) for well over a decade. to expect more than the good distance vision afforded by We have also seen a definite progression in premium IOLs monofocal IOLs.

The lens was designed to move anteriorly or and patients were happy. Today, we are posteriorly depending on the accommodative forces of doing an even better job, yet some patients the eye, thus providing distance and some intermediate seem not as happy. I think this is because vision. However, this technology has not been widely the bar of patient expectations has risen so high that it adopted because this lens type provided limited near and has become a different ballgame. We deliver outstanding intermediate vision improvements. 2 SUPPLEMENT TO CATARACT & REFRACTIVE SURGERY TODAY | JANUARY 2020
PanOptix Trifocal IOL The multifocal IOL splits light energy into two focal points. The two focal points are simultaneously presented to the retina providing distance and near or intermediate vision, depending on the add power. Essentially, we are talking about bifocal implants, which consequentially require patients to choose between having near or intermediate vision. The extended depth of focus (EDOF) IOL introduces an Figure 1. One approach to achieve trifocality is the application of sequential diffractive optics. elongated depth of focus and a range of vision from distance This is used with traditional trifocal IOLs. to intermediate. Yet, in order to achieve both functional distance and intermediate vision, we typically need to use some form of monovision to widen the depth of focus. What other approaches exist to provide a range of vision to our patients? Dr. Braga-Mele: Trifocal IOLs are the latest addition to the global PCIOL landscape. Trifocal IOLs produce a range of vision by splitting light energy into three focal points: near, intermediate, and far. Different optical approaches Figure 2. A theoretical IOL with four focal points (40 cm, 60 cm, 120 cm and distance) can be used to achieve trifocality in an IOL. Dr. Horn, may not provide sufficient light energy for distance, possibly effecting distance vision would you elaborate more on the distinct features of each performance, however when the 120-cm focal point is redirected to distance, you get optical approach and what it means to the patients? ENLIGHTEN technology. Dr. Horn: One way to achieve trifocality is to use the principal of sequential diffractive optics. Sequential diffractive optics creates an intermediate focal point that is located at 2 times the distance of the near focal point. For example, if the near focal point is at 40 cm, then intermediate is located at 80 cm (Figure 1). However, the most common intermediate vision activities are performed at arm’s length, or about 60 cm for the average height Figure 3. The PanOptix Trifocal IOL with ENLIGHTEN technology has three focal points (40 cm, 60 cm, and distance). person.2,3 Dr. Braga-Mele: How do we get to an intermediate focal result is a near foci at 40 cm, intermediate at 60 cm and point of 60 cm? distance, thus creating a way around sequential diffractive optics to optimize intermediate performance, while Dr. Horn: Using the principal of sequential diffractive maintaining excellent near and distance performance of the optics, one would need to place the near focal point at IOL. This design is ENLIGHTEN technology (Alcon). 30 cm to achieve an intermediate of 60 cm, which may The PanOptix Trifocal IOL utilizes 88% of the usable light be too close for the vast majority of patients.

A way around the ENLIGHTEN technology is designed to be less dependent on challenge is to use the non-sequential diffractive order pupil size or lighting conditions. The PanOptix Trifocal IOL approach, which leads to four focal points: a near at 40 cm, (Figure 3) allocates 50% of the available light to distance, 25% a first intermediate at 60 cm, a second intermediate at to intermediate, and 25% to near.5 120 cm, and distance (Figure 2). However, creating four foci may negatively impact distance performance.

At each simulated distance, Prof. Kohnen: Defocus curve studies comparing the the visual acuity of the patient is measured, which is plotted diffractive EDOF IOL to the PanOptix Trifocal IOL have as the defocus curve.
