How do I back up all of my Medmont Studio 4 data?

You only need to make a copy of one folder on your PC, the Data folder, to back up your entire Medmont Studio 4 database. You can copy this folder to a USB stick, network location or external hard drive and use either a manual or scheduled backup system to back up or archive your patient data.

This folder can be found in the following location on your PC (Server PC if running a multi-computer setup):

C:\Program Files\Medmont\Medmont Studio 4

This location is the default Data location for Medmont Studio 4. If your installation has been customised, this location may be different and you will need to contact your IT professional.

To make a backup of the folder, follow common 'copy & paste' practice to move it to your desired backup drive, media or network location.

How do I transfer exam results from one patient to another?

Transferring results from one patient to another (for one-off exams) is very easy in Medmont Studio 4. Select the desired exam, click the View menu and choose Details. Next to the Patient field, click the Change button. Locate and select the desired patient and click OK. The exam will now be automatically moved to the selected patient.

There is currently no way to change the allocated patient for a batch of exams (all at once). They must be changed one at a time using this method.

Can I enter a patient's address in my Medmont database?

There is no dedicated Address field for entering Patient addresses into your Medmont database. Medmont Studio is not designed as a practice management database, however if you wish, you can use the comments field in Details View. Click View > Details to access this view. Click the Comments tab to access and edit the Comments field.

Can I share out my Medmont Studio database out over my network so other users can see the exam results?

The standard license you receive when you purchase Medmont Studio is for a single user only, but this single user can log in from any terminal on your network which has Medmont Studio installed in Client mode; the restriction of the license is that no more than one person can be logged in at a time.

For example, you could have four workstations connected to your Medmont Studio server running on a standard single license, but no more than one of these workstations can be logged into Medmont simultaneously. 

It is possible to increase the number of concurrent logins by the purchase of additional session licenses. Contact us for more info.

How do I send exam results to someone as an image, for them to view or print without needing Medmont Studio installed?

Exporting exams from Medmont Studio using the File > Export feature results in a propietary file that works very well for transferring data between Medmont Studio-equipped PCs, but that cannot be opened without the software being installed. To save exams as an image, for M700 and E300 exams, you must first generate a print preview of the exam. The preview will then be saved as an image.

To do this, select the exam and choose File > Print Preview. The preview will now appear in a new window. From here, choose File > Save as Image. This will allow you to save the full preview in BMP, JPEG or GIF format (JPEG is recommended for general use, where BMP provides better quality at the cost of a much larger file size) to anywhere on your PC, e.g Desktop.

I have captured an E300 image but the analysis is missing in a large section of the eye.

The software needs to be able to clearly identify the central ring to provide a good analysis.

The operator should check that the central ring can be clearly distinguished when capturing the images. If the central ring is obliterated by a cut or abrasion, try getting the patient to look slightly up or down (or to one side) until you get a clear image of the central ring.

What Chord is Eccentricity measured at?

The E-Value displayed at the top left of the map display is measured at a set chord, which can be changed in the Tools > E300 System Settings menu (software default is 4.675mm)

Back to Top

How are shape factors and K Values Calculated?

The Shape Factor (k) is defined as follows:

k = 1 - a^2 / b^2

Where a and b are the half axes of the equivalent elliptical surface (a is the radial half axis and b is sagital half axes). For a normal prolate eye b > a and therefore k > 0. A spherical eye would have k = 0 and and oblate eye would have k < 0

The Eccentricity of an ellipse is the standard mathematical definition:

E = {1 - Min(a,b)^2 / Max(a,b)^2}^(1/2)

Note that eccentricity does not give an indication of whether the eye is oblate or prolate.

There are numerous ways of determining the best fit equivalent elliptical surface. All of these are approximations because real eyes are rarely symmetrically elliptical. The Medmont E300 finds the ellipse that gives the same apical curvature and curvature at a specified chord. We have found in practice that this method gives repeatable and reliable shape factor readings. Finding the ellipse that has the same apical curvature and sag height at a given chord is another method - however we found that this tended to be more sensitive to noise and not as reliable.

Because our E and K values are not derived from height data we do not recommend using them to generate height values.

They are intended to provide measurement of the shape of the cornea. If you need corneal height data we recommend that you use the height data calculated directly as part of the analysis. This height data does not assume that the eye is a symmetrical ellipse and is much more accurate then calculating height data from an apical curvature and E value.

The Sim K values are calculated by simulating the optics of a real keratometer with an angle of 23.1 deg.

I am receiving a error "ComExcpection error: The application has failed to start because its side-by-side configuration is incorrect" when upgrading Medmont Studio on my Windows Vista machine 

How do I install Medmont Studio on a PC for the first time?

Usually we will send out a technician to install your software for you when you purchase a Medmont instrument, but if you ever have to install Medmont Studio by yourself, you can follow the steps below:

IMPORTANT NOTE: Do not plug in your Medmont Instrument/s or USB License Dongle or install any Medmont hardware on your PC (such as the Leutron Capture Card for use with E300, or the USB cable connected to an M700 Automated Perimeter) until after installing the Medmont Studio software.

• Insert the Medmont Studio installation disc into your CD-ROM or DVD-ROM drive and wait for the menu to appear. From this menu, choose "Install Medmont Studio". Click 'Next' when the Welcome screen appears, then choose 'Everyone' and click 'Next' twice again to begin the installation.
• Soon the Configuration Tool will appear. Select Standalone as your configuration on the first screen (unless setting up a client/server setup; if so, select appropriate option for that PC, making sure to install Medmont Studio on the Server before installing on any clients). Click Next.
• Click Next twice. If you wish to integrate with a Practice Management System, choose it on this screen and click Next, specifying the data path for your system if prompted. If not, click Next with nothing selected.
• Click Next, then select the appropriate instrument/s for your practice. Click Next.
• On this screen
  - For M700 Automated Perimeter, select USB interface and Fixation Detection Camera.
  - For E300 Corneal Topographer, choose Leutron Card. 
  - For DV2000 Diagnostic Video Imaging, choose whichever drivers are appropriate for your own setup (these will vary depending on your setup - you may require IT assistance if you are unsure of your hardware.
• Insert the Medmont USB License Dongle into a free USB port on PC2. You will be presented with a Windows dialog that asks if you want Windows to connect to Windows Update to search for a driver. Choose No, then click Next. You will be asked if you want Windows to install the device automatically. Choose the default option (“Install the software automatically”), then click Next. This will install the appropriate driver for you automatically.·
• Plug in your Medmont instrument/s and install their drivers in the following manner:
  - For M700 Automated Perimeter: Turn on the M700 Automated Perimeter and connect the USB cable running from the perimeter into the PC. You may be prompted with a Windows dialog that asks if you want Windows to connect to Windows Update to search for a driver. Choose No, then click Next. You will then be asked if you want Windows to install the device automatically. Choose the default option (“Install the software automatically”), then click Next. This will install the appropriate driver for you automatically. Follow these same steps for any subsequent ‘Add New Hardware’ screens that follow.
  - For E300 Corneal Topographer: Turn off the PC and install the Leutron capture card into a free PCI slot on PC2 (this requires that you open your PC - you may require IT assistance if unsure how to install a PCI device). Plug the cable running from the E300 Corneal Topographer into the matching port on the Leutron card. Turn your PC back on. Follow the ‘Add New Hardware’ wizard in the same manner as for M700 above.
  - For DV2000 Diagnostic Video Imaging: Install any relevant software and drivers for cameras that you use with Medmont DV2000 software.
• Open Medmont Studio 4 from the desktop icon or the Start menu. It will not yet recognise your license (you have not yet entered your activation key), so the software will be in Single User Review mode, a mode in which new exams cannot be launched. Click into the Tools>License Manager menu. A Dongle ID should already be visible (if it is not, Windows has not correctly installed your license dongle and you will need to seek IT help
• Click the Edit button next to the Activation Key field and enter your Activation Key as provided by Medmont, then click Ok. You will now see your licensed components listed in the License Manager screen. Close the license manager. Your setup is complete. You can now begin using Medmont Studio.

How do I update Medmont Studio to a newer version?

Updating your Medmont Studio 4 software to a newer version is much simpler than installing it from scratch. This is because of all your imstrument drivers and data exist on your system already and only the software itself requires updating.

To update your software to the newest version of Medmont Studio 4, follow the steps below:

• Back up your current database on your server by making a copy of the folder C:\Program Files\Medmont\Medmont Studio\Medmont Studio 4\Data as per your own regular backup procedures.
• Go to our Downloads page and download the latest version of our software, choosing to Save (rather than Run) when prompted. Choose Desktop as the destination. If you are updating from a version prior to v4.9.0, you will also need to download the Microsoft .NET Framework v2 software. If you have Medmont Studio installed on multiple PCs, download the updater onto your server first. This same file can then be transferred over the network or via a USB stick or other media to allow other PCs to run the update without downloading it again.
• When you have downloaded the file/s to your desktop, run the Microsoft .NET installer first if required (only required if upgrading from a version prior to v4.9.0), then run the Medmont Studio updater. Choose the default selections all the way through the installer (this applies to both installations). Medmont Studio will remember the configuration of your previous version and automatically default to those selections, allowing you to simply click 'Next' all the way through the setup unless something specific has changed in your setup (NOTE: you do not need to tick the boxes regarding drivers for your instruments. These will default to an unticked state as they have already been installed).
• Click Finish when prompted.
• If running a multi-computer setup, repeat these steps for all client machines (except for the first step; only the Server needs to be backed up).
• Your software is now up to date. To verify that the new version has been installed correctly, open Medmont Studio and click the Help menu, then choose About Medmont Studio. The new version number will appear.

I am receiving the error "Dongle Not Detected" when I open Medmont Studio 4 and I am now unable to create new exams.

This error indicates that your Medmont license dongle is not being detected by your PC. In this case, the software automatically switches into a mode called Single User Review, in which exams can be viewed and printed but new exams cannot be created. To resolve your issue, your valid license information needs to be present and viewable in the License Manager screen, which is accessible from the Tools menu in Medmont Studio.

Follow the steps below to resolve your issue:

I am receiving the error "Could not connect to server on 192.168.XX.XX" when I try to open Medmont Studio.

This error indicates that you are running Medmont Studio in a networked environment and your PC cannot establish a connection with the Server. 

The first thing to check when you receive this error is whether you have an active network connection. Any easy way to test this is to try to open a web page in Internet Explorer. If it fails to open, you have a basic connectivity problem and should consult your IT professional immediately for assistance. 

The next thing to consider is whether your AntiVirus or firewall software may have recently updated itself or changed its settings, inedvertantly blocking Medmont Studio. To see if this is the case, try completely disabling your antivirus and firewall on both the server and client PC/s on your network. 

Be aware that you are disabling your PC's protection against malicious attacks and viruses when you turn off these systems. Ask your IT person to disable your internet connection during this testing if this greatly concerns you. Also, ensure that you immediately turn these systems back on after testing.

If access to Medmont Studio is restored with these systems disabled, something has happened in your Antivirus or Firewall software which has blocked Medmont Studio, and you will need to get your IT person to configure the software to restore access to Medmont Studio.

If you are still receiving the same error, please contact us for assistance

I am receiving an error when I try to open Medmont AT20R; "The AT20R software could not find the BlueTooth Dongle"

It is quite common for Windows XP to install the wrong driver when you insert the Medmont AT20R Bluetooth Dongle.

To see if this is the case, open the Control Panel, then click into System > Hardware > Device Manager. From here, you may see a section at the top called 'Bluetooth Radios', with a device inside called 'Microsoft Bluetooth Enumerator' or 'Generic Bluetooth Radio'. If so, Windows has incorrectly installed its own driver.
To resolve the issue, right-click on the item 'Generic Bluetooth Radio', then choose 'Update Driver', and elect to manually search your computer for the appropriate driver. When prompted, select 'CSR BlueCore BlueTooth as the correct driver from the list, then proceed and complete the wizard.

You will now find the device name 'CSR Bluecore Bluetooth' in the Universal Serial Bus Controllers section rather than the Bluetooth Radios section. Your device is now installed correctly. Restart your PC and double click on the AT20R icon to begin using your software.

I am receiving the error 'Unable to initialise video hardware' when I start a new M700 exam

*NOTE: This article only relates to the above error if the following error details are also displayed:

                    Title: Unable to initialise Video Hardware
                    Error: DeviceError
                    Reason: Connect(CapturePin, vmr9InputPin) failed 

This error is caused by a conflict between Microsoft's DirectX drivers and some video cards; particularly legacy video cards and low end or on-board/integrated graphics cards. When you update to a new version of Medmont Studio, this error may be triggered if your PC uses such a card.

The only way to fully resolve this issue is to install a more modern video card into your PC, specifically one that fully supports Microsoft DirectX 9 (VMR9 Support is the precise feature requirement).

Alternatively, you can work around the issue by disabling the crosshairs used for alignment reference without the need for a new video card. This will allow you to conduct exams, but the alignment crosshairs in the video feed will no longer appear.

To do this, you will need to have Medmont Studio v4.11.2 or newer installed. Close Medmont Studio and download the VMR9 Disabler here. Save the file to your Desktop and extract and run the file 'Disable.reg’ once downloaded. When prompted, click Yes and OK. Restart Medmont Studio. Your fixation window will be restored.

If you wish to reverse this fix, you will need to re-enable VMR9. To do this, Close Medmont Studio and download the VMR9 Enabler here. Save the file to your Desktop and extract and run the file 'Enable.reg’ once downloaded. When prompted, click Yes and OK. Restart Medmont Studio. Your alignment crosshairs will be restored, but the exam screen will only function if you have installed supported video hardware.

I am receiving the error "An unexpected error (Unable to cast transparent proxy to type 'Medmont.Data.DataObjectServer')" when I open Medmont Studio.

This error indicates that not all PCs which run Medmont Studio on your network are running the same software version. For example, if you have recently run a Medmont Studio software update on a client PC but have not run the update on the server PC, this error will occur. 

To resolve this error, simply install the latest version of Medmont Studio 4 on all PCs on your Medmont Studio network. The latest version of Medmont Studio 4 can be downloaded here.
