This innovation is helping to ensure that those patients who cannot attend physical screenings frequently do not miss out on the opportunity to be screened.
- Government spending and technological funding: Many developed countries that spend a significant amount per capita on health care are now directing more funds towards the development of advanced ophthalmic diagnostic systems. For instance, the U.S. spends the most on healthcare per capita in the world, and tonometer are used in most basic eye examinations. In September 2023, OCULUS brought to the clinics in the U.S. the DARWIN and LUCENT systems to provide enhanced eye treatment. These technologies, coupled with the funding for AI-based diagnostics, are making way for the use of multifunctional tonometry devices in clinical environments.
Challenges
- Skewed access in low-income regions: The availability of tonometry is still a challenge in the underserved and rural populations, which reduces the chances of early management of avoidable blindness. According to WHO, while there are actually 2.2 billion people with low vision or blindness, 1 billion of them could have been treated if they had been diagnosed at an earlier stage. Such discrepancies are mainly attributed to the absence of infrastructure, clinical equipment, and qualified healthcare workers in these areas, which underlines the importance of utilizing novel and affordable approaches to address this issue.
- Regulatory compliance and standardization issues: The tonometer market faces challenges due to ongoing changes in the safety and performance standards of medical devices, which results in constant updating and adjustment of standards to meet safety concerns and product outcomes. Also, variations in the regulatory environment across the world may lead to the slow deployment of devices across the global markets, which affects the tonometer market growth and timely availability of innovative tonometry solutions for patients around the world.
