Instruments: A thorough examination

I was able to try out the new dry eye assessment option recently made available for the latest incarnation of the Visionix, the 120+ (see Optician 07.02.2020). While I had the chance, I took the opportunity to assess a few patients using the full armoury of tests on offer, and here present some of the results achieved.

The main selling point of the Visionix 120+ (figure 1) has to be the wide range of tests it is able to undertake. After entering the usual patient data, or selecting an existing patient on the database, you can then select from a range of diagnostics, each with set associated tests. For example, as shown in figure 2, selecting the ‘corneal application’ tells the machine to undertake wavefront analysis (aberrometry), topography and pachymetry. ‘Refraction’ triggers autorefraction and wavefront analysis. It is also here where the new ‘dry eye’ function’ is selected and which is a standalone battery of tests.
