Summary

The newest generation Lucia 621 has a step vault design that is claimed to provide excellent positional and refractive predictability. In order to explore the positional stability, anterior chamber depth stability is examined as marker for haptic buckling comparing positional behaviour after conventional and femtosecond-laser assisted cataract surgery.

Detailed description

In order to explore the positional stability, anterior chamber depth stability is examined as marker for haptic buckling comparing positional behaviour after conventional and femtosecond-laser assisted cataract surgery. Furthermore, the refractive outcome of CT Lucia 621P/PY is examined, providing optimized (en bloc optimization) formula constants for both, conventional and femtosecond-laser assisted cataract surgery for Haigis, Hoffer Q, Holladay I, SRK/T and Castrop formulae. Besides ACD, further parameters for IOL stability are examined (IOL tilt/decentration) and consequences for the aberration profile are described.
