Hypothesis : Phacoemulsification is superior to SICS with regards to: * Immediate unaided high and low contrast visual performance * Its impact on quality of life.
Phacoemulsification procedure * Infiniti Vision System with Software 2.03 or higher, OZil handpiece (HP) * Anaesthesia: topical * Incision: temporal clear corneal 2.2 mm single plane * CCC and hydrodissection, sculpting and division using step by step chop in situ and lateral separation, I/A. * Single-piece AcrySof IOL (SN60WF) in the bag SICS procedure * Anaesthesia: peribulbar * Incision: superior scleral tunnel 6.5 to 7 mm * CCC and hydrodissection * Nuclear expression: blumenthal technique using anterior chamber maintainer, manual cortical clean-up * Single-piece PMMA (MZ60BD) in the bag
