IPCL implantation showed a reliable visual outcome with an efficacy index of 1,06. The average post-operative UDVA (0,23 logMAR) is worse compared to the ICL (UDVA -0,01 logMAR) but can be attributed to the suboptimal average pre-operative CDVA (0,29 logMAR). The diffractive IPCL, implanted in a presbyopic population (average age 48 years), provided good post-operative UDVA (0,06 logMAR) and UNVA (0,04 logMAR) with little visual side effects.
