Primary Outcome Measures

Name	Time	Method
1. Postoperative uncorrected and best-corrected visual acuity for far distances is assessed with LogMar and ETDRS charts for each eye at 1 day, 7 days, 1 month, 3 months and 6 months <br>2. Postoperative uncorrected and best-corrected visual acuity for intermediate distances (60 cm) is assessed using the Jeager eye chart for each eye at 1 day, 7 days, 1 month, 3 months and 6 months <br>3. Postoperative uncorrected and best-corrected visual acuity for near distances (33cm) is assessed using the Jaeger eye chart for each eye at 1 day, 7 days, 1 month, 3 months and 6 months <br>4. Additional correction (diopters), in order to achieve best-corrected binocular visual acuity at intermediate and near distances, assessed with trial lenses during visual acuity examination with Jaeger eye chart for both eyes at the preoperative time and 6 months after surgery
