Study design l.jpg
Study Design Crystalens HD Patients

  • Retrospective analysis of 80 patients

  • Single surgeon (UD)

  • Examination of the distance vision eye only

    • To avoid benefit of mono-vision / mini-mono

  • Near vision measured through best-corrected distance vision


Evaluation l.jpg
Evaluation Crystalens HD Patients

  • Patient Age: <65 65+

  • Prior LASIK: yes no

  • Axial length: <26mm>26mm

  • Capsulorrhexis: <5.5mm >5.5mm

  • IOL Orientation: vertical horizontal


Age younger or older l.jpg

Problems with my study l.jpg
Problems with my Study Crystalens HD Patients

  • Patients fell into multiple categories:

    • Prior LASIK more common in younger patients

    • Long Axial Length more common in younger patients and prior LASIK patients

  • Not enough patients

  • Post-op timing of results should have been consistent

  • Need longer follow-up in post-op period

  • Near vision not always measured at 16 inches


Conclusions l.jpg
Conclusions: Crystalens HD Patients

  • No statistically significant answers

  • Suggestions (Not Proven):

    • Prior LASIK patients may do better perhaps due to other ocular aberrations

    • Patients with an Axial length > 26 mm may do better due perhaps due to thin IOL, optics.

  • Needs further analysis
