Objective: The new generation of aspheric foldable lenses is implantable over smaller incisions and facilitates beneath the biaxial also microcoaxial phacoemulsification.
Methods: We investigated 30 consecutive patients with an ADAPT AO implantation on one eye, Akreos MI-60 on the other eye, randomised.
Exclusion criteria were beyond others corneal scars and iris pathologies. 6 weaks post op we determined objective refraction, subjective refraction, UCVA, BCVA, contrast sensitivity (CSV 1000), corneal and total aberrations (Wavescan and Pentacam), corneal topography (Oculus Keratograph and Pentacam) and IOL-centration (photograph and digital evaluation)
Results: The variance of the target refraction (A-constant 118.9; IOLMaster) was 0.001 D. for the MI60. Contrast sensitivity at 3,6,12 und 18 cpd without glare was equal in both lenses, with glare results were slightly better in ADAPT AO, but not statist. significant. BCVA was 20/20 for both lenses. Spherical aberration (WASCA) valued 0.24 µm (ADAPT AO) and 0.25 µm (MI60) in mean. There was no statistically significant difference according to the intraocular IOL-centration.
Conclusions: Both intraocular lenses presented excellent results regarding visual acuity, contrast sensitivity, spherical aberrations and IOL-cenetration. The A-constant of 118.9 (IOLMaster) for the MI60 intraocular lens is confirmed by our results.
