Purpose: : To customize IOLs with high repetition rate-focused femtosecond pulses using the Phase Wrapping Algorithm to allow higher diopter changes within a limited space.

Methods: : Focused femtosecond laser pulses can increase the refractive index of the lens material. Different patterns of refractive index modifications can provide different diopters within a limited space when using the Phase Wrapping Algorithm.

Results: : Refractive Index Shaping (RIS) has been utilized to modify the optical property of IOLs, the phase wrapping algorithm can be used to allow the shaping of higher diopter powers within the limited space inside the IOL. The necessary refractive index change can be achieved in Aaren’s standard hydrophobic 150ppm yellow dye / 0.8% UV absorber IOLs.

Conclusions: : Results suggest that customized IOLs can be generated with focused femtosecond laser pulses using the Phase Wrapping Algorithm.
