The fitting of soft contact lenses is a daily part of the workload of most contact lens practitioners. While there is much written on the topic, until recently there has been little scientifically derived evidence as to the key parameters with which to define soft lens fit. Most of the instruction on how to record soft contact lens fit can be found in common contact lens textbooks but, again, there is no consensus on soft contact lens fit evaluation and recording. This article reports on the schematic devised from the scientific research conducted at Aston University in the United Kingdom, to better understand which are the traditionally assessed features of soft contact lens fit independently contribute and hence are critical to record. The full description of the study can be found in the journal Contact Lens and Anterior Eye by the author.
