New BCLA CLEAR Series on Presbyopia

The eight reports are part of the BCLA Continuous Learning Evidence-based Academic Report (CLEAR) Presbyopia initiative, under the direction of Professors James Wolffsohn, Philip Morgan, and Shehzad Naroo, alongside around 80 experts from around the globe.

Presbyopia is common, impacting around two billion people worldwide. Despite this there are knowledge gaps and differing approaches taken by researchers and clinicians when addressing presbyopia.

The BCLA CLEAR Presbyopia authors have agreed that presbyopia:

“Occurs when the physiologically normal age-related reduction in the eye’s focussing range reaches a point that, when optimally corrected for far vision, the clarity of vision at near is insufficient to satisfy an individual’s requirements.”¹

The BCLA CLEAR Presbyopia reports cover the following topics:

1. Presbyopia definitions, by panel chairs,¹
2. Mechanism and optics, Professor Leon Davies,²
3. Epidemiology and impact, Associate Professor Maria Markoulli,³
4. Evaluation and diagnosis, Professor James Wolffsohn,⁴
5. Management with spectacles and contact lenses, Professor Philip Morgan,⁵
6. Management with corneal techniques, Professor Jennifer Craig,⁶
7. Management with scleral and pharmaceutical techniques, Professor Shehzad Naroo,⁷ and
8. Management with intraocular lenses, Dr Christina Schnider.⁸

The reports are published in the BCLA’s peer-reviewed journal Contact Lens and Anterior Eye. Summaries of each of the publications will be published in mivision, starting with BCLA CLEAR Presbyopia: Epidemiology and impact.
