About this briefing

About this briefing

Medtech innovation briefings summarise the published evidence and information available for individual medical technologies. The briefings provide information to aid local decision‑making by clinicians, managers and procurement professionals.

Medtech innovation briefings aim to present information and critically review the strengths and weaknesses of the relevant evidence, but contain no recommendations and are not formal NICE guidance.

Development of this briefing

This briefing was developed for NICE by King's Technology Evaluation Centre. The interim process and methods statement sets out the process NICE uses to select topics, and how the briefings are developed, quality‑assured and approved for publication.

Declarations of interest

  • David (Ted) Garway‑Heath has co‑authored peer‑reviewed scientific publications on the accuracy and precision of various tonometers (not including Icare). He is the International Glaucoma Association Professor of Ophthalmology, which has an interest in all aspects of glaucoma management. He is the Vice‑President of the European Glaucoma Society, which publishes practice guidelines and he sits on the guideline development group. Tonometry accuracy and precision is of fundamental relevance to the practice guidelines. He authored the response from Moorfields Eye Hospital to the draft NICE Guideline for the diagnosis and management of glaucoma and ocular hypertension. He is a co‑applicant on a successful NIHR i4i grant to develop a contact lens tonometer (due to be completed in 2016). If the development is successful, the contact lens tonometer could be a competitor to Icare in some (but not all) clinical scenarios (for example, home testing).

  • Peng Tee Khaw had a previous (one‑off) specialist consultancy on specific pharmaceutical issues relating to glaucoma and wound repair and regeneration from Celltech, Pfizer, Novartis, Alcon and Allergan and. He is co‑author in a research audit paper comparing Icare with Goldmann Tonometry in children (non‑sponsored).

  • No other relevant interests declared.
