PromTime is commissioned by the French Ministry of Health and funded by the National payer to participate in the transformation of health system

The French national payer has allocated €0.9 million to PromTime’s experiment

to launch a pioneering ecosystem that incentivizes practioners on high-value care for cataract surgery (decree published in the Journal Officiel de la République Française on July 30, 2020 and updated in the Journal Officiel de la République Française on November 10, 2023).

Health gains

Health gain measures the impact of a surgery on patients' visual quality of life in daily activities.

The goal is to compare health gains from 18,700 cataract surgeries for 11,000 patients by 2025. 

The objective is to demonstrate that value of care increases when patient outcomes are measured and shared

Health gains measure the clinical benefit of cataract surgery for patients. It is the difference between the patient’s visual abilities in everyday activities before and after surgery.


Through this experiment, PromTime introduces two pioneering innovations

Transparency model

The average health gains of medical teams are shared with patients, surgeons, independent professionals, payers, providers, and industrial partners.

A fee for sharing health gains

A Financial Incentive for Advanced Transparency (FIAT) encourages practitioners to generate and share patient health gains (€30 per case).

This experiment aims to demonstrate that transparency on health gains contributes to reducing the number of inappropriate surgeries, i.e., those associated with low visual benefits for patients.

The objective is to improve the health system efficiency by optimizing the number of cataract surgeries, which grew by nearly .
