Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The cataract surgery (550 000 operations per year in France) is to replace the cloudy lens with a refractive implant. Two colors of implants are available: white implants, filtering out ultraviolet and yellow implants, filtering and more blue light. No clinical data are available to assert the superiority of an implant according to its color and the choice is made according to the preference of the surgeon and / or "markets".

It is established in humans that blue light has an important role on the secretion of melanopsin, a key mediator of the circadian cycle. This "clock" regulates most neuroendocrine functions in the nycthémère (sleep, mood, temperature, cortisol, ..). The question of the impact of these neuro endocrine functions of the installation of a blue light filter into the eyes of patients operated thus arises.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Group 1 : white implant

Randomization will determine the color of the implant to be used for each patient for interventions in both eyes, white or yellow to know.

Group Type EXPERIMENTAL

white implant

Intervention Type OTHER

1. st intervention (in the month following the inclusion): Randomization of the color of the implant
2. nd operation (1 to 3 months after the first surgery): Installation of a same color as the first implant operated eye

Group 2 : yellow implant

Randomization will determine the color of the implant to be used for each patient for interventions in both eyes, white or yellow to know.

Group Type EXPERIMENTAL

yellow implant

Intervention Type OTHER

1. st intervention (in the month following the inclusion): Randomization of the color of the implant
2. nd operation (1 to 3 months after the first surgery): Installation of a same color as the first implant operated eye
