Objective:
To evaluate the visual and refractive outcomes of eyes implanted with the Crystalens HD and the
Crystalens AO intraocular lens.
Methods:
We retrospectively reviewed the records of 159 eyes of 100 patients implanted with the Crystalens
HD IOL and 108 eyes of 66 patients implanted with the Crystalens AO IOL. Visual and refractive outcomes preoperatively and postoperatively were assessed and compared between the lenses.
Results:
At 1 year, uncorrected distance VA was 20/30 in 78% of eyes in the HD and 76% of eyes in the AO
groups. Uncorrected intermediate VA was 20/30 in 90% of eyes in both groups. Uncorrected near VA was J3 in
92% in the HD and 90% in the AO groups. Comparing the two groups, the difference in uncorrected distance
(p=0.60), intermediate (p=0.77), and near (p=0.64) vision was not statistically significant. Spherical equivalent was
-0.42D +/-0.51D in the HD and -0.6 +/-0.48D in the AO groups (p=0.10).
Conclusion
Refractive outcomes were similar between the Crystalens HD and AO groups. Mild myopic refractive
outcomes were targeted and achieved in both lens groups. These refractive outcomes provided good uncorrected
distance, intermediate, and near vision postoperatively.
