Custom V Design Options
There is an option on the Crossbows software to allow a variable inset, and this only applies to the Custom V design. When this is enabled in the CrossBows calculator (from the Tools|Options menu), then for Custom V, the inset will be calculated based on variables like NWD, lens power, BVD etc. In this case the LMS should send the NWD, IPD, SPH, CYL, AX and BVD. If some values are missing, then defaults will be used or calculated.
The manual inset is to cater for the eye doctor who wants to have a specific inset for his or her patient and in this case the ERNRIN value should be used to directly specify the inset required. From the CrossBows documentation:
ERNRIN | numeric; | For supported designs, may be used to specify the addition inset between limits of 1.5 and 3.5mm. If a non-zero value is specified, this will override the AutoInset feature. |
To request a specific inset in Rx-Universe, use the VCA Overrides on the order (available beginning in 6.38.00):
For the automatic corridor selection the length of the corridor is returned in CORRLEN, the inset is returned in ERNRIN.
