[Validity of prediction after standard implant and the implant calculated according to the SRK formula]

The purpose of this study is to appreciate post-operative ametropia in pseudophakic patients (EEC and posterior chamber IOL). Two groups were implanted either with a standard 21 D IOL (group 1) or after calculation of implant power according to the SRK formula (group 2). Results show residual refractive errors over 2 D in 7% of case in group 2 and 22.3% of case in group 1.
