Portable tonometer for glaucoma prevention

Provide a one-line summary of your solution.

HealTech+ consists of a compact and affordable tonometer that uses an innovative method to detect and facilitate treatment of glaucoma.

What specific problem are you solving?

We are addressing the specific problem of limited access to eye care services and late diagnosis of glaucoma, particularly in underserved communities. 

Glaucoma is a critical problem affecting millions of people globally, especially those in rural areas or low-income regions with limited access to quality eye care. According to the World Health Organization (WHO), glaucoma is the second leading cause of late onset blindness in the world, and the primary cause of blindness for people over 60. In 2020, about 76 million people aged 40 to 80 were diagnosed with glaucoma, of which almost 8 million people could have been prevented or have not yet been treated. 

In Mexico alone, approximately 1.5 million people are affected by glaucoma, and up to 50,000 cases of blindness are attributed to late detection. The burden of visual impairments, including glaucoma, is more prevalent in Africa, Latin America, and the Caribbean, with higher rates among people of African and Latin American descent.

Access to quality eye care is an important factor in the risk of glaucoma progression and the results of its treatment. It is estimated that around 111.8 million people will be affected by glaucoma by 2040. And if this projected increase is not accompanied by greater access to eye care services, the number of people with glaucoma and blindness will increase substantially, especially in third world countries.

Early diagnosis is critical to preventing vision loss, but glaucoma often progresses asymptomatically and remains undetected until later stages. One of the current methods of identifying glaucoma is intraocular pressure (IOP) measurement, which can be done using a tonometer.

Our solution focuses on early diagnosis through the development of an affordable and easy-to-use patient-operated tonometer. This addresses the limitations of current tonometers that can only be used in clinical settings by healthcare professionals. By empowering patients to measure their own intraocular pressure outside of traditional healthcare settings and office hours, we aim to improve accessibility and quality of health services, especially for underserved groups like older adults and those with limited mobility. This approach enables early treatment for glaucoma without imposing significant expenses on users.

By ensuring more people receive timely diagnosis and appropriate care, we aim to improve continuity of care, reduce the likelihood of vision loss, and ultimately reduce the burden of visual impairments like glaucoma.

What is your solution?

My solution, called E.T. (Eye Tonometer), is a portable and accessible patient-operated tonometer that is easy to use, affordable, and reliable. E.T. uses an air puff to measure the pressure of the eye (IOP), providing early diagnosis, prevention, and ongoing screening to facilitate the treatment of glaucoma. Additionally, E.T. is paired with a mobile application that receives the IOP results and stores them in a digital file shared with the user's ophthalmologist, allowing for constant monitoring and prompt attention from the doctor.

The objective of E.T. is to democratize and make visual monitoring services more accessible, offering integrated and person-centered eye care. Furthermore, E.T. aims to change the perception about the importance of visual health.

If you require more specialized information about the technology, feel free to contact me via email.

Who does your solution serve, and in what ways will the solution impact their lives?

Both E.T. and the mobile application are focused on improving the quality of life of:

  • Glaucoma patients 

  • Patients at risk of glaucoma:

    • Developing country populations  

    • Older Age Groups (over 60 years)

    • Family Members with Glaucoma

    • Diabetics

    • People with high blood pressure

    • Myopic and hyperopic

Specifically, the target population of the solution are people over 60 years of age who suffer from glaucoma or are at risk, who must periodically attend an ophthalmologist for monitoring. However, they may face difficulties in following up on their treatment due to factors such as travel distance, limited mobility, financial costs, invasiveness of regular tonometers, or even situations like pandemics. Additionally, they may feel disappointed by the news of their illness and fearful of losing their sight.

My solution will give these people a portable and accessible tool with which they can remotely monitor their IOP, improving their treatment and reducing economic and travel difficulties. At the same time it will make them feel more confident with their medical follow-up and less fearful. 

As indirect beneficiaries, the aim is to generate a social benefit by favoring the relatives or individuals who share a household with the target population, who will also be able to monitor their intraocular pressure. Additionally, ophthalmologists and health systems will benefit by doubling or tripling the number of patients they can attend to, thus optimizing their time.

More About Your Solution

What makes your solution innovative and sustainable?

Our solution, HealTech+, is innovative and sustainable due to its unique approach to addressing the problem of limited access to eye care services and late diagnosis of glaucoma. We have developed a patient-operated tonometer that allows individuals to measure their own intraocular pressure (IOP) outside of traditional healthcare settings and office hours. This empowers patients, particularly older adults and those with limited mobility, to take control of their own health and enables early detection and treatment of glaucoma.

What sets our solution apart is its affordability, simplicity, and reliability. By leveraging technological advancements, we have created a tonometer that is easy to use, cost-effective, and provides accurate IOP measurements. This innovative approach eliminates the need for frequent visits to healthcare professionals and reduces the burden on healthcare systems. It also addresses the issue of late diagnosis by enabling individuals to monitor their intraocular pressure regularly, leading to earlier detection of glaucoma progression and improved treatment outcomes.

Our solution catalyzes broader positive impacts by democratizing access to glaucoma monitoring and care. By enabling individuals to measure their own IOP, we reduce barriers related to geographic location, financial constraints, and limited availability of healthcare professionals. This allows underserved communities, including those in rural areas and low-income regions, to receive timely and affordable glaucoma screening and monitoring. As a result, more individuals can receive early interventions, reducing the risk of vision loss and improving their quality of life.

Furthermore, our solution has the potential to change the market by disrupting the current model of glaucoma management. Traditional tonometers are primarily used in clinical settings by healthcare professionals, limiting accessibility and creating bottlenecks in the healthcare system. Our patient-operated tonometer shifts the paradigm by empowering individuals to take an active role in their own eye health. This not only improves efficiency and scalability but also transforms the patient experience, fostering a sense of empowerment and engagement in their own care.

In addition, the scalability of our solution allows it to be adapted for monitoring other ophthalmological conditions beyond glaucoma. By leveraging the same patient-operated approach, we can expand our impact to a broader range of eye health issues, further enhancing the sustainability of our solution.
