Post Surgical

Post-refractive fitting may require a two-step fitting process for those corneas which are significantly reverse geometry in shape.
  1. Optimize peripheral fit.
  2. Optimize central fit, using VA. Refer to fitting manual for more detailed guidelines.

First Checks

Next

Info

Expand the collapsable boxes to view some signs that would require immediate lens removal.

OK
Check the lens immediately after insertion for the following characteristics. (Expand the collapsable boxes for information.)

Bubbles

Indication:The lens is very TIGHT.
Action:Flatten the base curve by 0.40.
Guidance:Bubbles very close to the edge of the lens could indicate the lens is lifting in that location, i.e the lens is flat. Look for other fit characteristics, such as centration.

Fluting (lens lifting at the edge)

Indication:The lens is very FLAT.
Action:Steepen the base curve by 0.40.

Rotation > 10°

Stable straight ahead and upwards gaze

Indication:The lens is TIGHT
Guidance:For irregular corneas, compensating for an axis rotation over 10 in the prescription will mean the final powered lens will rotate to another position. The best fit is obtained when the laser mark is as near vertical as possible.
Action:Flatten the base curve by at least 0.20.

Unstable straight ahead and upwards gaze

Indication:The lens is FLAT.
Note:If all lenses demonstrate unstable rotation, Sector Management Control may be required. For more information about SMC, go to Ultravision KeraSoft IC product information.
Action:Steepen the base curve by 0.20.

If you observe any of these characteristics click back to select a new lens, otherwise click next.

Info

After assessing Movement, Rotation and Centration, the app produces this intermediate report which indicates whether the lens is showing signs of being a sub optimal fit. If this is the case, you can either proceed to gain more information from Comfort and VA or remove the lens and choose a more suitable one.

OK
Before assessing Comfort and VA with over refraction, review the fit so far. Click the info button for more information.
The fit appears to have some red lights. You can either proceed to comfort and VA to gather more information or you can select a new lens now.

MoRoCCo Va (Post Surgical)

Next

Info

Comfort is an important indicator of fit. A generally "edgy" lens indicates a flat fit whereas a lens that is initially comfortable, but becomes uncomfortable over time, indicates a tight fit. Patients who have been experiencing discomfort with other lens types may feel a flat lens is comfortable until they experience an optimally fitting KeraSoft IC lens.

OK

Info

Over Refraction VA should be better than spectacle VA and be relatively close to that achieved with other lens types. If VA is very much worse than with other lens types, does not improve with other STD lenses the cornea may have a flat periphery and require a lens with a FLT peripheral change.

MoRoCCo Va

Next

Info

You have now reached the final report page. The app shows all the results from each of the observations for the lens on eye. Although all five MoRoCCo VA characteristics have to be taken into consideration, rotation and VA and their stability take priority in assessing overall fit and this is reflected in the overall advice.

It is also useful to note that if you order a lens with rotation more than 10 degrees, the laboratory may request you reassess the fit. When fitting an irregular cornea, rotation shows that the fit is sub-optimal and that the final powered lens will rotate to another position.

About

The MoRoCCo VA App is designed to assist with fitting KeraSoft IC lenses from the 8 lens Fitting Set. The App will allow you to directly input, via interactive screens, exactly what you observe during your fitting assessment. From this, an indication can be given whether the fit is optimal or sub-optimal and advice on what steps to take next.

In cases of more complex corneal shapes, more advice may be required from technical support from the laboratory. In these cases, the report can be emailed to yourself so that you have a record to forward on if needed.

After assessing Movement, Rotation and Centration, the app will produce an intermediate report indicates whether the lens is showing signs of being a sub optimal fit. If this is the case, you can either proceed to gain more information from Comfort and VA or remove the lens and choose a more suitable one.
