I purchased my OPD Scan III about a year ago. I’m using it in my practice to increase efficiency. I previously had the OPD Scan II and I upgraded to the OPD III for the increase in technology that this unit offers. One of the things I like about my Scan III is that it gives me better measurements. So, when I send patients out for surgery we can look for toricity, corneal toricity and see if they need a toric IOL and I can explain that to the patient. Also, in contact lens fittings, the information received allows me to fit contact lenses much faster because of the information provided. From a refractive point of view, it gives me my starting point much easier so that when I see my patient it only takes me about a minute or less to refine their prescription so that it can be used in my practice. Another advantage of my Scan III is that, with my staff, it is easy to use and learn. Also, when patients come in, there’s a “wow” effect from the technology that my office has that other offices in my area do not have.

I love the topo and the higher order aberrations calculations on the OPD. It helps me to show and explain to those difficult to refract patients why they can see as well as they want to be able to see. The OPD and TRS in series integrate seamlessly with our EMR. This allows us to import all that important data without the fear of data entry errors. Plus it is so much faster and efficient for the patient to have that data imported into our EMR.

I purchased the OPD-Scan III which replaced my OPD-Scan II. The old system gave me great results for six years but the new one is amazing! My office runs more efficiently and I believe it is much more accurate. There have been a number of times that I have put in the “wavefront” prescription and have gotten better results than the patients subjective. The patients like the blue light better - they say it is easier to look at. Thank you, Marco, for the new and improved OPD - I am saving more time and it does make the day more streamlined.

All of my patients have technician-guided topography and OPD-Scan III performed as part of a comprehensive eye examination. I then review the data with the patient in the examination room, making sure to connect any anomalies to his complaints. Having topography data available for every patient has shown me many cases of corneal conditions that I might not have detected otherwise. I’ve even saved marriages with it. A 60-year-old truck driver had a chief complaint of nighttime glare that was shaped like a cross. His wife thought he was making it up, but I was able to show her a point-spread function map that clearly demonstrated the cross-shaped glare that was being generated by the patient’s cataracts.

Marco’s OPD combines refraction, topography, wave-front analysis and a host of other features all into one ergonomic package. The OPD gives tremendously more information with one click than most traditional practices could ever hope to gain with any and all of their current equipment. Ultimately the diagnostic capabilities of the OPD not only aid the doctor in ascertaining a more complete picture of the visual system but also help to provide a more clear and concise explanation to the patient as well. Best of all, it feeds directly into my EHR, save me time and decreasing costly transcriptions errors.

Sometimes, I’m surprised by what the topography reveals, especially if I obtained a good refraction and the patient is seeing well. I’m reminded of the value of the OPD-Scan III every time I diagnose heretofore undetected pathology, such as keratoconus or pellucid marginal degeneration. This instrument simply helps me to be a better doctor.

The OPD-Scan III system is an integrated aberrometry system. It combines the attributes of a placido topographer, automated refractor, and automated keratometer, and adds the elements of wavefront aberrometry and pupillometry. By integrating these systems into one multifunctional unit, we can quantitatively evaluate how light is focused throughout the visual system. It provides us with both low-order aberrations, which in essence are the traditional refractive measures of sphere, cylinder (and axis), and high-order aberrations (such as spherical aberration, coma, trefoil, etc.). Furthermore, the OPD can identify the source of these aberrations and differentiate between external (typically anterior corneal and tear film) and internal aberrations (typically lenticular in origin, such as cataract, IOL anomalies, or posterior capsular opacities).

The highly precise measurement of higher (3rd and 4th) order aberrations with modern wavefront aberrometry can now identify and accurately measure a patient’s irregular astigmatism and spherical aberrations. At the “clinical awareness threshold” these “higher order” aberrations (HOAs) begin to decrease the “quality of vision” and undermine the likelihood of ⅛ D sensitivity.

I have found the OPD to be a most valuable asset in my practice. All I ever wanted in practice is an unfair advantage. That is what I feel I get with the OPD coupled with digital refractors. My well vision patients don’t have to answer "which is better, one or two" very much. In fact I have found the Wavefront refraction is so accurate I only need to flip cylinders a couple of times a day. I simply make small spherical adjustments and I am done. Digital refraction takes less than 30 seconds in most cases. My patients love the freedom from the stress of manual refraction and I love the unfair advantage OPD Scan and digital refraction gives me in the marketplace!

Though we knew little about the new OPD-Scan III, I’m very glad we were able to experience all of the advantages of the new device. I’ve been very happy with it for numerous reasons, the most important being that the information it provides has helped dramatically in determining which IOLs are best for our patients. We have a much better idea, for example, who will have satisfying outcomes with multifocal lenses.

One of my patients had IOL calculations that reflected a lot of cylinder. This would have been a toric patient, but as soon as I saw my OPD III printout, the top showed me this very interesting asymmetric astigmatism. It looked like a “C” right in the middle of the cornea. It happened to be the perfect size for a Goldmann tonometer, so the OPD III was able to pick it up. If I hadn’t seen that, I would have operated on this patient and put in the wrong lens. Luckily, the OPD III showed me what was going on, so I was able to bring the patient back on a later date, get the right IOL Master measurements, and perform the correct surgical procedure.

You’re getting this in a single instrument, not multiple instruments. Without the OPD-Scan III, you have to use a topographer, move the patient to the aberrometer, and then move the patient again to do pupillometry. With the OPD III, you get everything in one shot with perfect registration, so you see exactly what the curve is, and you see the interior-internal-posterior dimension in the same location

We wanted something that would combine and automate testing in an inline fashion that allowed comparisons between important aspects of the refractive and anatomic states of the eye. It also had to be quick and efficient to use so we could screen every patient who came into the practice. The OPD-Scan III fulfills those needs.

I purchased the OPD because I wanted to have a number of diagnostic devices and wanted to find a way to have it presented in a fairly efficient manner. For me it provides an autorefraction, a wavefront refraction, a topography, and lets me look at high order aberrations of the eye and cornea all under one setting.

The OPD-Scan III helps me reach a goal of zero spherical aberration with my cataract patients. A few years ago, I studied how accurately and predictably dynamic skiascopy, the wavefront technology used measures spherical aberrations and guides IOL choice. When I chose from three different IOLs based on data from the device, postoperative spherical aberration for 40 patients was just +0.019±0.051 μm. When we can virtually eliminate spherical aberration for our cataract patients, we increase patient satisfaction. In particular, when patients have other visual problems that we can’t correct, even a relatively small change, such as reducing nighttime glare, can make a big difference in their lives.

The reason I got the OPD to begin with, we were having a lot of people who we put multi-focal implants in, and most of them were happy but a sizable minority were unhappy. And I learned later that part of that reason is that some of these people who are unhappy had some problems with their eye that we weren't picking up. It might be a large angle kappa, it might be corneal coma, it might be dry eyes. And my original reason for buying the OPD was to help me with those patients. With a very quick OPD scan, I'm getting exactly what their mesopic and photopic pupils are. I can see what the angle kappa is, I know their spherical aberrations, their corneal coma. We have a beautiful scan where I can see their placido rings on the cornea, it gives us an idea of how much dry eye there is. There is a lot more information and you can see it all on one sheet. It's really helpful. We probably do fewer multi-focals than we used to, but we have happier patients now.

The Marco OPD-Scan III is very useful - if you do a lot of refractive cataract surgery you can't live without it. We use it pre-op on all patients and I look at spherical aberration, topography, K's, angle kappa, etc. Shame one cannot get reimbursed for its use mostly, but we love it! For toric and multi-focal IOLs it’s an absolute MUST HAVE. The training by Marco is also secondary to none. We just bought our second OPD.

The OPD-Scan III is a great way to check your surgical technique post-operatively and one of the most common post op problems, whether its LASIK or PRK, is dry eye. You can show a patient, on the OPD, that they are perfectly centered, no prescription but you see all these little speckles? That means your eye is bone dry and it is ruining your optics. You can also subtract out corneal aberrations from the whole eye aberrations so you can find out if there is an early cataract that is going to make a 50 year old patient unhappy after a LASIK procedure. The OPD is such an invaluable tool - being able to sort that out; it educates me and it educates the patient and that maybe we should be talking about a refractive lens exchange instead.
