A healthy combination

The move towards combination units has been ongoing for some years now. Desktop units providing a number of functions, such as non-contact tonometry, autorefraction and keratometry, are familiar in many pre-screening areas. Clear benefits include the freeing up of space in a busy practice along with improving the efficiency of the pre-screening process. If a unit can undertake several different measurements without the need for patients having to be moved from machine to machine, this not only speeds up the whole process but obviously will make the experience less onerous for the patient. The new Tonoref III (UK distributor Birmingham Optical) is a useful step up from the well-established Tonoref II unit familiar to many, with an expanded range of functions that should prove attractive to the practitioner.
