Design outcomes

Primary

MeasureTime frame
Primary end point(s): Primary end point is evaluate the mydriasis at capsulorrhexis (limiting procedure during cataract surgery). Mydriasert will be efficient if just before the capsulorrhexis pupil diameter is equal or higher than 6.5 mm. Also stability of the mydriasis will be evaluated from t30 to t90 and during full surgery time. Mydriasis obtained with topical treatment will be compared with mydriasis obtained using Mydriasert and it will be asessed if mydriasis obtained in both cases is continous in the time, especially during surgery time: this could facilitate a more confortable surgery filed for the investigator. Surgery will be divided in 5 different times for measuring pupil dilatation: T1: before 1st incision T2: before the use of viscoelastic T3: before the capsulorrherxis T4: after the phacoemulsification T5: after intraocular lens implant ;Timepoint(s) of evaluation of this end point: Primary end point will be evaluated at inclusion visit, surgery visit or D0;Main Objective: -Determine pupilar diameter induced by Mydriasert at capsulorrhexis (equal or higher than 6.5 mm). -Determine pupil diameter and mydrisis stability induced by Mydriasert at t30, t45, t60 and t90 after the use of the ocular insert in the eye of the patient. Determine if Mydriasert is able to induce a mydriasis equal or higher than the topical treatment used as comparator. Measurement of mydriasis stability also will be determined not only at previously mentioned times but also during surgery time: surgery has been divided in 5 times when investigator must measure pupilar dilatation.;Secondary Objective: -Determine if there is a relationship between the use of Mydriasert for pupil dilatation and presence of macular oedema. Identify the number of cases of macular oedema at each group of treatment, the macular thickness and stability of the dilatation for each patient. Investigator will perform the measurements during the surgery at 5 different times. -Determine systemic and local tol

Secondary

MeasureTime frame
Secondary end point(s): -Systemic tolerability of the IMP: determine cardiovascular parameters before, during and after surgery. -Local tolerability of the IMP: determine ocular symptoms. Patients should describe symptoms associated to Mydriasert (placing, maintenance and removal of the insert). During the long of the study investigator will evaluate ocular signs and symptoms. -Local and systemic safety: adverse events will be monitored. Local adverse event related with macular oedema will be especially monitored -Investigator assessment related to efficiency and satisfaction -Suitability of Mydriasert by the nurse assessment;Timepoint(s) of evaluation of this end point: -Local tolerability will be evaluated at D0, surgery visit or inclusion visit. Also at D1, D14, D30 and D90 -Local and systemic safety will be evaluated at D0, D1, D14, D30 and D90. Macular thickness measurement will be done at D1, D30 and D90 -Investigator assessment will be evaluated at D0 -Suitability of Mydriasert will be evaluated at D0
