Create A New Patient and Capture Map Video 2


This is Video 2 on creating a new
patient as well as capturing a Corneal Topography with your Medmont E300. Start by creating a new patient in the
top left hand corner clicking on the, ‘New’ button. Entry into your patient details, Last Name, First Name, tab to the ‘Date of Birth’ using the arrow keys you can scroll
through day, month, and year, or you can click on the pull down menu and scroll through to find the appropriate Month and Date of Birth. with the arrow keys you can tab over to the Year or click your cursor on the Year and enter the appropriate year of birth. Next you can click on ‘Clinical’ and entry
any procedures such as ‘Lasik’ that this patient may have you can click on ‘Conditions, to select any conditions that apply you could create your own categories to separate your patients into different groups, anyone of these columns can be changed to add specific
procedures, conditions, or categories that you would like specific for your practice. You can also entry in the patient RX, in this window, it’s not required but if you were designing contact lenses
from the Medmont Contact Lens Module if you enter the RX here it
automatically imports every time you create a contact lens from the module of the software you can also click on ‘Comments’ and add
any additional information on the patient. When you’re done click save and the patient will be created on the
database side of the window, on the left hand side. Once that patient is highlighted in blue to capture topography click on the ‘Corneal Topography’ icon along the top. Once the capture window is up you’ll notice is live video a running in
the bottom lefthand corner. Take your joystick and moving the joystick left or right you can center that green cross hair
to the Apex Ring of the Placido Reflection off the
Calibration Ball or off the eye the red line tells you how close are far
away you are, well the red line is at the top of the
Runway the instrument is too far away from the
eye, while the red line is that the bottom of the Runway, the instrument is too close to the eye move the instrument back until the
redline lines up on top of the green cross hair. Place the green cross hair by moving the joystick bringing the two, both the distance
indicator, the red line, and the green cross hair, controlled by
the joystick, over the Central Ring. Once the two line up over the Central
Ring you’ll notice the instrument automatically captures you do not need to click a capture
button the instrument is a continuously running video that automatically grabs images when they are ideal. You’ll note that along the top we now have
four images presented from ninety nine percent through ninety
nine percent the rightmost image will always be your best percentage capture, or the highest confidence the instrument has in the reading you’ve taken. Anything over ninety five is considered
valid. So any readings above ninety five and
you may save those to the file. Anything below ninety five you want to
continue to better center the instrument to idealize the capture. Before saving make sure that you right click, select your ‘Zoom’ tool, and zoom in on the central ten to
fifteen rings. You want to be sure that there isn’t any tear film break-up that happened during the point when that photo was taken. Tear film break-up will distort the
accuracy of the topographer by distorting the rings, when the rings are not parallel and even the instrument could have extrapolation
error, or it could have error in calculating the shape or elevation of the eye. If the rings are parallel and even, such
as you see here, this would be a quality reading. You can click ‘Save’ and now that map is saved into the patient file. Nothing is in the patient file until you
click ‘Save’. If you’re not satisfied with the images click, ‘Clear’ images, and go back in and capture again. Capturing on the human eye is very fast just simply center that green cross hair
and that red distance indicator it should take only seconds with an experienced user. At present were capturing on the
Calibration Ball this is an excellent way to learn how to do the calibration when you’re new to the Medmont Topographer. The Calibration Ball doesn’t move and it
doesn’t blink like the human eye and it doesn’t have moving tear film like the
human eye, so this is an excellent way to capture and improve your skills prior to
capturing on patients. Make sure again that with each
capture you take you zoom in and ensure that the central rings look
parallel and even. On the Calibration Ball of course the
rings will be utterly parallel and even. Click ‘Save’ if you’re satisfied with your
image and that image has now been saved to the patient file. This concludes the video on Creating a New Patient and Capturing a
Corneal Topography
