In this episode Dr Melissa Barnett – a Fellow of the BCLA and Global Ambassador for the BCLA – interviews Dr Deborah Jacobs about medical use of contact lenses which is a solution for many complex ocular conditions, including high refractive error, irregular astigmatism, primary and secondary corneal ectasia, disfiguring disease, and ocular surface disease. The development of highly oxygen permeable soft and rigid materials has extended the suitability of contact lenses for such applications. There is consistent evidence that bandage soft contact lenses, particularly silicone hydrogel lenses, improve epithelial healing and reduce pain in persistent epithelial defects, after trauma or surgery, and in corneal dystrophies.

Drug delivery applications of contact lens hold promise for improving topical therapy. Modern scleral lens practice has achieved great success for both visual rehabilitation and therapeutic applications, including those requiring retention of a tear reservoir or protection from an adverse environment. This report offers a practical and relevant summary of the current evidence for the medical use of contact lenses for all eye care professionals including optometrists, ophthalmologists, opticians, and orthoptists. Topics covered include indications for use in both acute and chronic conditions, lens selection, patient selection, wear and care regimens, and recommended aftercare schedules. Prevention, presentation, and management of complications of medical use are reviewed.

Dr Barnet and Jacobs cover some of these aspects in this episode, but don’t forget that you can access the full report – which contains more in depth coverage of this research – from the BCLA website.

BCLA CLEAR is an initiative that has drawn together thousands of research papers on many different aspects of contact lenses into one place. The findings were published in, Contact Lens and Anterior Eye, the BCLA's scientific journal, in April 2021 under ten reports. BCLA CLEAR was facilitated by the BCLA, with financial support by way of Educational Grants for collaboration, publication and dissemination provided by Alcon and CooperVision.
