The OPD-Scan III efficiently provides exam data, which keeps patients happy in a busy, one-ophthalmologist practice.

Our practice chose the OPD III because of its efficiency, ease of use for our staff, and the power in data gathering it combines that other machines don't offer.  In just a few seconds, I can have imaging that can be analyzed in a multiplicity of relevant ways for evaluating the best possible candidates for intraocular and corneal surgery, and also the undisclosed poor candidates preoperatively.

I have used other companies and their products. The attention to detail and the customer service AFTER the point of sale is what sets Marco apart and is why I will be a repeat customer.

The OPD-Scan III machine has been absolutely invaluable to my practice. I perform it on every single one of my cataract patients at their pre-op visit.  The information that it gives me is crucial when trying to determine the correct lens choice for the patient.  Obviously, the corneal topographer is very helpful in assessing the level of astigmatism and helping guide my patients to a Toric lens implant, if needed.  Also, the assessment of higher order aberrations in the cornea is very valuable when determining whether or not my patients are candidates for Multi-focal lens implants.  The angle kappa and angle alpha measurements are also very important when determining whether to implant a Toric or Multi-focal lens.  It is also helpful to look at the internal OPD map to make sure that everything makes sense with regards to the astigmatism axis and magnitude.  I have become so dependent on the machine in my pre-op evaluation that I feel lost if I am unable to obtain a measurement (which hardly ever happens.)

My staff loves the OPD-Scan III because it is easy to use and fast.  Patients love it because they don’t have to go from instrument to instrument and I can visually show them why we can correct their vision or why not. This amazing device supplies all in one Wavefront Aberrometer, Auto Refractor, Pupillometer, Auto Keratometer and Placido Disc Topography. Using this sophisticated technology gives my patients the highest quality of care and is why my patients have a high satisfaction rate and send their friends. My practice owes the success of my premium IOL conversions to the OPD III.

With one highly reliable and consistent device, the OPD, I can quickly measure multiple parameters that allow me to match the best IOL with the patient’s visual goals.

I think the OPD Scan is a wonderful tool, especially for patients who have had multifocal implants. I have certainly, as any other surgeon, had--have had a physician--a patient with an outcome that is less than ideal.  I can think of specifically one patient who presented after his surgery with a corrected vision of 20/25 in J1, a nicely done surgery with a nicely centered implant and was still unhappy. So, we went back and started looking at what could be the cause.  We looked at the posterior chamber implant, and it was clear with minimal posterior capsule fibrosis.  And we also looked at the cornea and everything was fine.  So, we went back to the OPD.  We noticed his preoperative measurements were very normal.  His cornea was clear.  He was a good candidate.  That was the case at one week postoperatively as well.  And then, we looked at the OPD, and the nice thing about OPD is that it really splits your aberrations into the cornea and the posterior segment, the internal OPD, and this is where it becomes really important.  It is truly an aberrometer of the entire eye.  And when we looked at his posterior, or the internal OPD, we noticed that there were quite a few aberrations there.  There were still less than before surgery, but it was very clear that the aberrations were coming from there.  So, we assumed that the aberrations were most likely coming from his minimal posterior capsule fibrosis but weren’t sure.So, we were able to convince him to wait a little bit and re-measure those aberrations in a few weeks.  In a few weeks those aberrations increased.  And indeed, we then knew that the aberrations were coming from the posterior capsule fibrosis and not from the lens.  And we were able to reassure the patient and explain to him that with a simple laser procedure he would be able to--we would be able to help him improve his visual outcome and do not need to worry about possibly explanting the implant.

It’s not easy to tell exactly which lens a patient needs, so it’s a very nice thing that the OPD III and IOL station software automatically chooses the best lens for the patient. There’s no one particular lens that’s good for all patients, but the software helps you choose the right one so you can address the spherical aberration and achieve what you want to achieve.

I am thoroughly enjoying using the OPD-Scan III. It has already become a fully integrated and invaluable tool in my office.  There are numerous ways that I use the OPD-Scan III in my every day clinical exams.  Immediately after becoming trained on it I was able to use it for patient education and diagnostic purposes.  I use it for preoperative evaluation of all refractive surgery and cataract patients. It is an amazing tool for both pre- and post-operative assessment of toric IOL patients.  I find that the autorefractions and wavefront refractions are spot on, and this has saved valuable time for my technicians in the clinic. Now that I have an OPD-Scan III, I can't imagine practicing without one.

The OPD-Scan III helps to measure the corneal spherical aberration, so we select the proper IOL to match the aberration.

Barrett Ginsberg

As a startup practice specializing in advanced cataract surgery and corneal surgery, the OPD-Scan Ill was one of my initial investments due to its multi-functionality. It has quickly become a quintessential piece of machinery used in our practice. Its execution of autorefractions and corneal topography is precise, granting shorter office visits and cost efficiency for our patients. Unlike other corneal topographers used in the past, aligning the patients whilst simultaneously maneuvering the OPD is smooth, making human error and patient uneasiness obsolete. Due to its precise measurements and accessibility, the OPD is a wonderful asset to our practice.

Arun Gulani

The OPD-Scan III helps us to understand the reasons patients complain whether they came for the first visit after getting glasses from the optometrist and looking into refractive surgery of a premium surgery so we can have a satisfactory outcome.  To me, practice efficiency is more important than seeing how many patients you can see in an hour, it also means consistent outcomes that you and the patients aim for.  So you get practice efficiency from the OPD for many reasons: 1) Takes up very little space with all-in-one tests in one station 2) The speed of doing the test and the ease of which the staff can get trained and comfortable is excellent with repeatable consistent data which is very important to me when using technologies like these.  I have happy patients, less re-treatments, more consistent outcomes - that is the higher level of excellency.

Faisal Haq

When I do an OPD measurement, it actually gives me refractions under mesopic and photopic conditions. Depending on the patient, I’ll give them a night pair of glasses or I’ll give them one pair for nighttime driving and one for the day. The OPD really helps us to accomplish this and helps us really help our patients in a way that we weren’t able to do so before.

The OPD-Scan III performs many functions in seconds. If a practitioner understands its multiple scanning methodologies they will raise their level of care to their patients. Pupillometry, IOL positioning, retro illumination of cataracts, angle kappa, tear film evaluation, corneal topography, corneal power assessment for post refractive patients, and other functions makes this instrument a fundamental requirement to practice in the 21st century. All of this is collected in seconds! We have come to recognize in our practice that OPD is a necessity - not luxury. After you learn how to use the myriad of functions that is collected in seconds, you can use them to educate your patients and enhance their confidence in you - their 'expert'.

Bonnie Henderson

Of all the technologies that I utilize for preoperative evaluation of my cataract patients, I believe the OPD-Scan III is one of the most important. I depend on the OPD III to evaluate the astigmatism, aberration, and topography of the cornea. It is also extremely useful to check the toric IOL placement after surgery if rotation is suspected. I use the OPD III on every single one of my preoperative patients.

Bonnie Henderson, MD

Richard Hoffman

I have found the OPD to be an invaluable tool for both pre-operative and post-operative evaluation of our patients. The diagnostic summary allows me to assess and confirm the need for toric IOLs and limbal relaxing incisions and we now perform this as part of our preoperative work up in most of our cataract patients. The wavefront refractions have also been extremely reliable and helpful for our difficult refractions in pathologic eyes. Our technicians find it easy to use and everyone is pleased with the additional diagnostic information available.

Mitchell Jackson

We added the OPD-Scan III to increase efficiency in the practice and capture as many data points as possible in the shortest amount of time. It delivers corneal topography, wavefront analysis, higher-order aberration data and angle kappa for both eyes in 20 seconds or less. That indirectly allows us to see more patients per hour, which improves our bottom line. It gives me a lot of bang for my buck and a superior understanding of the total visual system.

Mark A. Jank

The OPD-Scan III amasses in a single source a multitude of information that is necessary for modern IOL selection and cataract surgery. Instead of moving patients around for testing, we take them to one workstation. From their perspective, it’s one test. The OPD-Scan III not only gathers the essential data more efficiently, but it also gives us data that we didn’t even know were essential until now.

Cynthia Matossian

I use the OPD-Scan III to help me best customize the implant to each patient. By looking at the data the OPD III provides, I can select which implant best suits the eye of the patient.  Sometimes we use a different implant in one eye and in another eye, it all depends on the eye’s quantitative number that I’m able to obtain from the OPD. Also, I am able to demonstrate these maps in the exam room to the patient so both the patient and/or family member is able to understand it; a disease process or their ocular numbers so they can best accept my recommendation whether it be a toric implant or monofocal implant or multifocal or even an accommodative implant.

Marguerite McDonald

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.

JC Noreika

Assessing the patient’s visual system beyond mere refractive error, the OPD-Scan III sets itself apart from basic auto-refraction technology. It is an elegantly designed, sophisticated instrument enabling the provision of enhanced vision care to a broader, more discerning and challenging patient population.

Larry Patterson

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.

Richard Prince

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.

Richard Prince, MD

James Salz

The OPD helps me achieve the desired outcomes for both cataract and laser refractive surgeries.Before I choose an IOL or decide on limbal relaxing incisions, I need answers. Does the patient have astigmatism? Is it corneal or lenticular? Is it symmetrical or asymmetrical? What size is the pupil? Are there corneal aberrations? The system also lets me show patients a map of the aberrations in their visual system. They see how much spherical aberration they have, and I explain what that means in terms of halos and glare, which helps us agree on an appropriate treatment.

James Salz, MD

Jonathan Solomon

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.

Kerry Solomon

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.

Kerry Solomon, MD

Jonathan H. Talamo

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.

Toby Tyson

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.

Paolo Vinciguerra

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

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.

Kim Castleberry

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!

Lou Catania

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 D sensitivity.

Barry Eiden

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).

Ben Gaddie

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.

April Jasper

The OPD is more accurate than any autorefractor I've ever worked with and the wavefront analysis is fabulous. It's important to know why those challenging patients don't refract to 20/20. The system has improved the accuracy of RGP fits (even pellucid and keratoconus), with most fits correct the first time. The OPD has solved many a dilemma for me and saved my patients from unnecessary referrals.

Lori Lippiatt

For relatively uncomplicated refractive cases, this technology speeds up workflow, eliminates transcription errors, and improves the patient experience. For more complicated or difficult cases, this technology can pull the curtain back on why a patient can't achieve 20/20 vision (due to higher-order aberrations) and has trouble with night vision (refractive differences in corneal power as pupil size increases).

Scot Morris

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.

Brett M. Paepke

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.

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.

John Warren

Not only does the OPD-Scan III provide information more quickly and have the tracking horizontally, vertically and in and out to provide better and quicker data acquisition, but the sheer amount of data that is delivered is quite amazing.  There’s really not a facet of the patients’ refractive system that’s not evaluated by the OPD. Topography has wonderful coverage and I get a little bit bigger of a shot through the large pupils, especially for some of my younger patients.  This allows me to understand their night vision shifts and how their vision changes as the pupil gets larger in those patients.

Troy White

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.

Michael Wood

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.

This machine is a game changer. With the OPD-Scan, you’re not going to have many returned prescriptions. You see the difference. You have confidence.
