E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Primary efficacy variableThe primary efficacy variable is response based on the realisation of the capsulorhexis without use of any additive mydriatic treatment. A responder is defined as a patient for whom the capsulorhexis is performed without use of any additive mydriatic treatment.Additive treatments are for both groups any supplementary drug with a mydriatic action other than planned by the protocol, and/or the use of medical device for opening the pupil, between the first instillation of study product and the capsulorhexis.Co-primary efficacy variableThe co-primary efficacy variable is response based on the realisation of the capsulorhexis without use of any additive mydriatic treatment and the measurement of pupil size just before capsulorhexis (T3). A responder is defined as a patient for whom the capsulorhexis is performed without use of any additive mydriatic treatment and for whom the pupil size at T3 is greater than or equal to 5.5 mm. |
|
E.2.2 | Secondary objectives of the trial |
Secondary efficacy variables
-Pupil size measured at the time T4.
-Pupil size measured at the times T1, T2, T3 and T5.
-Assessment of patient's discomfort at T1 to T5.
-Time necessary for obtaining sufficient mydriasis :
-For T2380 group : Delay between the first injection and T3-For reference group : Delay between the first instillation of mydriatic and T3
-Questioning about the number of supplementary drops or injection necessary to maintain mydriasis
-Questioning about the number of supplementary drops or injection necessary to maintain anaesthesia.
-Delay between the first instillation (mydriatic for reference group, tetracaine for T2380 group) and the first incision.
-Delay between T3 and cefuroxime injection
-Total surgical time (first incision to cefuroxime injection)
-Assessment of the surgeon statisfaction of each stage (2nd incision, capsulorhexis, phacoemulsification, cortex aspiration, IOL implantation).

E.5 End points |
E.5.1 | Primary end point(s) |
The primary efficacy variable is response based on the realisation of the capsulorhexis without use of any additive mydriatic treatment. The co-primary efficacy variable is response based on the realisation of the capsulorhexis without use of any additive mydriatic treatment and a pupil size just before capsulorhexis (T3) greater than or equal to 5.5 mm. Patients for whom the data are not available to determine responseare considered to be non-responders.The statistical hypothesis tested is the non-inferiority of T2380 to the reference treatment. A two-sided 95% confidence interval on the difference in responder rates between the T2380 group and the reference treatment (T2380 minus reference treatment) will be derived to assess the hypothesis.T2380 will be declared to be non-inferior to the reference treatment if the lower bound of the 95% confidence interval on the difference in rates between the two treatment groups is greater than or equal to -7.5%. |
