| Measure | Time frame |
|---|---|
| Main Objective: The primary aim of this study is to evaluate mydriasis obtained with T2380 on patients with small pupils. The primary efficacy variable is the ability of the surgeon to perform a circumlinear capsulorhexis with a stable pupil size of at least 5 mm without using any other method to dilate the pupil.;Secondary Objective: The secondary efficacy variables are: • Pupil size measured at the times T1, T2, T3, T4 and T5 • Total surgical time (first incision to IOL implantation) • Assessment of patient’s discomfort at T1 to T5 • Assessment of the surgeon satisfaction of each stage (2nd incision, capsulorhexis, phacoemulsification, cortex aspiration, IOL implantation). ;Primary end point(s): The primary efficacy variable is the ability of the surgeon to perform a circumlinear capsulorhexis with a stable pupil size of at least 5 mm without using any other method to dilate the pupil. ;Timepoint(s) of evaluation of this end point: In order to realise the measurement of pupil size at specific times, surgery will be divided into 5 time periods according to the scheme mentioned in the protocol. Nota Pupil size measurement: The exact pupil size during surgery will be obtained following the formula: Pupil size = photo pupil size X corrective factor* (*) corrective factor = real HVID / photo HVID with HVID = Horizontal Visible Iris Diameter (i.e. horizontal white to white). Real HVID will be measured using IOL master during the selection visit. Photo HVID will be measured on each photo taken at 5 stages during the surgery. | — |

| Measure | Time frame |
|---|---|
| Secondary end point(s): Principal secondary end point of surgery will be T1, T2, T4 and T5 ;Timepoint(s) of evaluation of this end point: The pupil size will be measured on photos taken from surgery video recordings at the 5 times of surgery: • Just before the first incision (T1) • Just before OVD injection (T2) • Just before capsulorhexis (T3) • Just before IOL injection (T4) • Just after IOL implantation (T5) | — |
