Lee 1 1 ASA-Vision Clinics Seoul Comparative Analysis Preliminary Results of a Multicenter Study. 2 year follow-up Presbyopia Correction with AcrySof ReSTOR, Customvue Monovision and Wavefront-guided Monofocal Advanced-Surface-Ablation ( ASA-80 ® )
S. Lee/M.Kim 2010 Study Design Add requirement (mean): +2.20D ± 0.51D ( Near Vision < Nieden 4 ) Prospective multi-center clinical trial. 3 sites (between 08/2008 and 03/2010) Total of 360 eyes of 180 consecutive patients: Age (mean): ± 5.81 years Follow up after 1, 6, 12 and 24 months AcrySof ReSTOR: n = 120 (eyes) with bilateral implantation of ReSTOR multifocal IOL (Alcon) CustomVue Monovision Lasik: n = 120 (eyes) treated with the VISX STAR S4 Excimer Laser and the Femtosecond Intralaser FS60. ASA80 : n = 120 (eyes) Wavefront Guided Advanced Surface Ablation with the MEL80 Spotscanning platform (Carl Zeiss Meditec)
S. Lee/M.Kim 2010 Statistical Analyses SPSS v.15.0 All tests used were nonparametric, based on Kolmogorov- Smirnov-Test: no parametric t-test for significance; instead: Wilcoxon, Mann-Whitney-U, Kruskal-Wallis-Test.(p< 0.05) Advanced Surface Ablation (ASA80 ® / ASA-Lasek ® ) MEL80 Ablation Profiles: –TSA – (Tissue Saving Ablation) Type Munnerlyn-profile with k- value compensation –ASA – (Aberration Smart Ablation) Type TSA plus aspheric component = SAP: Standard Ablation Profiles –NAP: New-individual-Aspheric-ablation-Profiles ASA + Z(4,0) ▬ Addition of negative spherical aberration ▬

S. Lee/M.Kim 2010 Summary Acyrsof Restor IOL Implantation shows the best results regarding combined Far and Near Vision, thus leaving the patient postoperatively with a reduced intermediate Vision and reduced values for glare vision and mesopic contrast sensitivity. Customvue Monovision shows statistically significantly disadvantages of the clinical outcomes, especially regarding binocular visual acuity for Far and Near Vision. Respectively, after 6 months results improve, probably due to the learning curve, to use the eyes separately: one for Far and one for Near. (ASA80®ASA-Lasek®) Advanced Surface Ablation (ASA80®/ASA-Lasek®) : adequate combined Far and Near and IntermediateVision, additionally with a statistically significantly increase in Contrast Sensitivity und daylight and mesopic conditions. Conclusion Restor IOL´s and ASA80 are promising approaches for the treatment of presbyopia in patients with and without a cataract.
