Objective

To establish a standardized sharpness index for the evaluation of the optic edge design of intraocular lenses.

Methods

Common intraocular lenses [a hydrophobic acrylic IOL made by TechnoMedTechnology (model AL-MP301), two hydrophobic acrylic IOLs made by Alcon (AcrySof® and AcrySof® MA30BA), two hydrophobic silicone IOLs made by Pharmacia & Upjohn (CeeOn® model 911A and CeeOn® Edge model 911), a silicone IOL (model SI 146), a hydrophobic silicone IOL made by Human Optics (model MS 612), a hydrophilic acrylic IOL made by Human Optics (model CF acrylic) and a hydrophilic acrylic IOL made by Corneal (model TZ 118 SE)] were evaluated in the same way as in the first part of this paper and the results as well as the outcome of clinical studies of these lenses were compared to results of our previous paper.

Results

The AL-MP301 as well as the AcrySof, AcrySof MA30BA, CeeOn 911A and the SI 146 showed edge design features similar to those we had found to be effective for the prevention of PCO. The CeeOn Edge 911 could not be evaluated. The edge design of the other 3 lenses was not sharp but the area above the edge measured more than 13,5μm2.

Conclusions

Results show a significant influence of optic edge design on the prevention of PCO. Further clinical studies need to verify the correctness of the sharpness index.
