1182: the J&J Tecnis Eyhance IOL

I am thankful to the engineers who continually improve our surgical products through technical advances. These engineers are usually smarter than the doctors (definitely smarter than me) and they give their best effort to push the envelope of what is possible. I always welcome new technology and innovations for cataract surgery because they allow us to offer our patients more options to deliver the desired visual results. As ophthalmologists, we must also separate the marketing and the push from the sales representatives from the actual optics and the science. We never want to be in the position where patients believe that a magical outcome is possible and that we can mysteriously cheat physics. Let’s be straight here: we cannot cheat physics and there is no free lunch when it comes to optics!

Today we are talking about the new (for USA) Johnson & Johnson (J&J) Tecnis Eyhance IOL for cataract surgery, models are Tecnis DIB00 for pre-loaded or ICB00 for the stand-alone IOL. This is a new monofocal IOL which is built on the previous Tecnis ZCB00 platform (ZCBOO is colloquial speak) and, in my opinion, is an incremental improvement to that lens. In this press release from J&J Vision, the Eyhance is clearly labeled as a monofocal IOL “designed to slightly extended depth of focus” — the key word there is slightly. The Eyhance is not classified as a presbyopia-correcting extended depth of focus (EDOF) lens implant.

This article and video are entirely my personal opinion and figures are presented under the fair use educational review criteria. I do not have any disclosures or financial relationships to J&J (many years ago when the Tecnis platform was part of AMO: Advanced Medical Optics, I was a paid consultant to them). The Tecnis Eyhance comes with Directions For Use (DFU) which you can find at the manufacturer’s website here.


Should you click on the link and go through the DFU? Reading the DFU is not optional for surgeons, but rather it is required — at least in my view. While the patient has done “Google homework” and the sales rep has given her/his pitch, the bottom line will be found in the DFU. Note that there was NO separate FDA study done for the Tecnis Eyhance DIB00 / ICB00. In an email to a J&J representative I learned that, “There was no FDA study for the Eyhance as it was a level A modification that did not require clinical data.” Got it — an incremental improvement and not a revolutionary change. Let’s keep that in mind and temper our expectations.

The typographical error “dept of focus” instead of “depth of focus” is present in the actual DFU from J&J Vision.

This DFU reveals that the incremental change in the Tecnis monofocal (ZCB00 or ZCBOO) is a central 1 mm diameter zone of the aspheric anterior surface that creates a small continuous increase in central lens power. This is shown in the picture above which is from J&J and is presented here under the fair use for educational review (this is important in the USA when we use materials from others).

In the DFU for the Tecnis Eyhance DIB00 & ICB00 (colloquially called Tecnis Eyhance DIBOO and Tecnis Eyhance ICBOO) it clearly states that “clinically meaningful extension of depth of focus has not been demonstrated in clinical trials” (boldface/italics of the ‘not‘ is by me, but the official text definitely says “not”). It goes on to state that “in general, extended the depth of focus negatively affects the quality of vision at far distances,” which correlates well to our knowledge that you cannot cheat the physics of optics.

I think that the Tecnis Eyhance is a good incremental upgrade over the standard Tecnis ZCB00 (ZCBOO in colloquial terms) and that it is a really good monofocal IOL. It is NOT an extended depth of focus IOL like the J&J Tecnis Symfony (diffractive technology) or the Alcon AcrySof Vivity (beam-shaping technology), and patients should absolutely NOT expect to get an extended depth of field sufficient for reading vision (20 inches or closer) with this lens.

As you can see, there is no free lunch when it comes to the physics of optics. The total number of photons that enters the eye is going to be the same, but we can change how we distribute this light energy. In this MTF graph we can see that light energy is taken away from the red zone and then added to the green zone in order to increase the depth of focus by a slight amount. This is NOT an extended depth of focus lens and unless you have really, really long arms (1 meter), it will NOT give reasonable reading vision without glasses.

Data from this publication (which was sponsored by Johnson & Johnson as a promotional piece) shows that there is about 0.5 diopters (at most) of increased depth of focus compared to the J&J Tecnis ZCB00 (ZCBOO) which also comes with a mild drop in the vision at far distance. Note that both of these options, Tecnis ZCB00 and Tecnis Eyhance, offer MUCH better vision and MUCH better range than the cataracts that they replaced. If you are a patient reading this, stop now and go to a trusted cataract surgeon and just ask for the “omakase” option where the surgeon will give you her/his best. There is no way that a patient can do enough “Google homework” to become a junior ophthalmologist!

In the real world, this incremental improvement to the Tecnis monofocal platform means that you will likely get just 1 additional line on the eye chart without glasses as compared to the Tecnis ZCB00 (ZCBOO) at the 66 cm mark. Yes, that is 66 centimeters which is about 26 inches for our USA friends. Extend your arm, straighten your elbow, point far away from you, and the tips of your fingertips are at about 66 cm if you are my height (181 cm). If you are shorter than average, then your extended fingertips are not long enough to show what 66 cm is and you should use a tape measure! At this range of 66 cm, there is only 1 additional line on the intermediate vision chart and that is a very mild or very modest upgrade. In J&J Vision’s words, this is “sightly” better than the Tecnis ZCB00 that we have used for many years.

The J&J Tecnis Eyhance is a good choice for a MONOFOCAL lens implant, keeping in mind that it is NOT a true Extended Depth of Focus (EDOF) presbyopia-addressing lens implant. If patients are willing to tolerate a little bit of myopia (such as -0.5 diopters), then choosing that as a refractive target will give more useful intermediate and perhaps near vision. The patients who insist on sharpest distance vision (0.0 or plano in both eyes) will be more reliant on reading glasses for intermediate and near vision.

I really LIKE the Tecnis Eyhance and I think that I would choose it over the standard Tecnis ZCB00 (ZCBOO) for 95% of my patients who want a Tecnis monofocal (single-focus) IOL. These patients will get great distance vision and a slight increase in the vision at 66 cm, which is the range of looking at someones face across a dinner table, with only a small decrease in visual quality at far distance. Without glasses, these patients CANNOT expect to gain any useful reading vision, computer laptop vision, cell phone vision, or even chopping vegetables vision with this lens while maintaining optimal distance vision. To the patients who expect a free upgrade to reading vision without glasses with the Tecnis Eyhance while having sharp distance vision, your lofty expectations will not likely be met. Sorry, but we all know that you cannot cheat the physics of optics!

click below for the full video about my opinion of the J&J Tecnis Eyhance IOL:


  1. Have done about 200 DIB00’s. So far my patients are generally pleased and my surgical techs love the pre- loaded feature.

  2. Biggest problem is the nontoric Eyehance is reimbursed as a basic nontoric monofocal but JNJ is pricing it to the ASC above the cost of other monofocals and the pt can’t be balanced billed for it, so the facility is screwed JNJ did not think that through well

  3. Thank you, this was a great review of the lens and I understand it better. I have the same issue with the cost of the lens. I would have to charge the patient for the lens because the reimbursement of standard lens is lower than this lens. I will try to use it with toric so I can charge patient for an upgraded lens.

    1. I agree that J&J Vision needs to take a step back from the marketing and the push for much higher costs when the actual change and optical benefits are very modest. Even the J&J Eyhance toric is being priced at 33% higher than the J&J Tecnis toric.

  4. Went to my ophthalmologist in Reading, Pennsylvania last week. I told him I was doing internet research and considering the Eyhance or Vivity. He took a memo pad and wrote “Uday Devgan MD” and told me to look at your pages. I already had. As a patient working on my ‘junior ophthalmologist’ merit badge, I really do appreciate the work you do as a public intellectual, presenting the facts with candor and in terms that a layperson can understand. -Kevin McCloskey

    1. Kevin … Did you go with the Vivity, the Eyhance, or something else? I like the idea of both eyes Vivity doing a -.5D monovision instead of both eyes Eyhance with -1.25D on the second eye to do monovision.

  5. I need to have surgery on both my eyes and i’ve been reading your IOL lens reviews.I’m opting for a Monofocal lens.Which lens do you think is better ? The J&J Eyhance or Alcon Acry Soft IQ lens?

    Thank you for all the information for provide.

  6. Thank Dr. Devgan for your most excellent review of the Enhance IOL and comparing it to the standard monofocus IOL, and making it understandable. I finally understand what has been placed in my eyes. My surgeon implanted the standdard J&J monofocus lens and I’m okay with that as I requested the best distance vision possible.
    You are absolutely right, we can’t cheat optical physics, it is what it is. As I understand one can’t improve intermediate and near vision without impacting far (plano) vision at least a little. Correct me if I am wrong.

  7. Surgeon originally recomended Vivity for me. In researching this I found I would loose dim and nightime contrast which is unacceptable for me. Being a part time rancher I do a lot of work at night. Asked to drop back to monofocal lenses, but the sugeon suggested this Eyhance lens as it would give 30% better low light contrast over the monofcal. I am thinking this maybe a mix up and what was meant was a 30% increase over the vivity.
    Do you know which is correct?

  8. Choose a different surgeon. Why choose a surgeon who won’t respond to you?!?! Come to LA and see me if you want the best.
