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 fi tting.
Hence, the evaluation of soft contact lenses varies greatly between individual practitioners and the record of lenses trialed is often limited to descriptions such as “good” or “poor” which is highly subjective and of limited use in future patient aftercare. It is acknowledged that practitioners have limited time for evaluating and recording contact lens fit. However, accurate recording of contact lens fit characteristics is important, for example:
- Legally, particularly in case of future contact lens complications
- To assist in reducing the risk of contact lens discontinuations
- To allow the practitioner the advantage of being able to read comprehensive clinical records on previous lens fit attempts which were ultimately unsuccessful and to avoid these issues with subsequent lens fitting.
The May article on our online Green Club platform, by Prof. James S Wolffsohn, 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 that independently contribute and hence are critical to record.
