To examine instillation success rates of glaucoma eye drops across different products and patient characteristics, and to develop predictive models aimed at improving patient outcomes based on product features.
Approach:
Key Findings:
Instillation success rates varied significantly across different glaucoma eye drop products, indicating a need for product improvement.
Patient characteristics such as age and sex influenced the success rates, highlighting the importance of personalized treatment.
Product design features, including squeezing force and container shape, were critical in determining instillation success, suggesting areas for design enhancement.
Interpretation:
The findings highlight the importance of both patient and product characteristics in achieving successful glaucoma eye drop administration, suggesting that targeted product design improvements could significantly enhance patient outcomes.
Limitations:
Survey responses may be subject to bias, as they rely on self-reported data, which could affect the accuracy of success rates.
Exclusion of patients using assistive devices limits the generalizability of the results, potentially overlooking a significant patient demographic.
Conclusion:
Improving the design of glaucoma eye drop products could potentially increase instillation success rates, thereby enhancing treatment efficacy for patients.
