Robert G. Martin, MD Donald R. Sanders, MD, PhD Following Implantation of 4 Foldable Lens Designs Higher Order Aberration Higher Order Aberration
2
Study Objective Objective Of The Study Was To Determine If Implantation Of Different Foldable Lens Designs Resulted In Different Amounts Of Higher Order Aberrations
3
Study Design Patients Had Tracey VFA Performed On Eyes To Undergo Cataract Extraction Patients Were Randomly Assigned To Receive 1 Of 4 Foldable Lens Designs Tracey VFA Was Repeated At 1 Week Postoperatively Patients Had Tracey VFA Performed On Eyes To Undergo Cataract Extraction Patients Were Randomly Assigned To Receive 1 Of 4 Foldable Lens Designs Tracey VFA Was Repeated At 1 Week Postoperatively
4
Pupil Size All pre and postoperative measurements of higher order aberrations were done with a 4.5mm pupil size
5
Foldable Lens Designs STAAR Collamer STAAR Plate Haptic Silicone ALCON SA-60 AMO Sensar STAAR Collamer STAAR Plate Haptic Silicone ALCON SA-60 AMO Sensar
6
Preoperative Total Higher Order (HO) Aberrations No Significant Difference Between IOLs
7
One-Week Postoperative Total Higher Order (HO) Aberrations Collamer significantly better than STAAR plate and Alcon SA-60 (p< 0.005) N = 21N = 24N = 19N = 16
8
Collamer IOL Collamer Had Significantly Less HO Aberrations Than STAAR Plate And SA- 60 (P 0.005). Difference With Sensar Was Not Significant. Collamer Had Significantly Less HO Aberrations Than STAAR Plate And SA- 60 (P 0.005). Difference With Sensar Was Not Significant.
9
Note Sample size may be too small, especially with the Sensar group, and results could change with a larger sample. However, we have strong clinical indications that less higher order aberrations are induced with the Collamer lens as compared to plate lenses and AMO lenses.
10
Pre-op – Average H.O. Aberrations STAAR Collamer Alcon SA-60 STAAR Plate AMO Sensar
11
Postop – Average H.O. Aberrations STAAR Collamer Alcon SA-60 STAAR Plate AMO Sensar
12
Summary Three Other Foldable Lenses Tested Had Between 55% and 117% More Higher Order Aberrations at 1 Week Postoperatively than the STAAR Collamer IOL
13
This Is A Study Of Optical Aberrations Is it clinically significant? Is this especially significant in patients with large pupils? Do we need a bigger implant? Do we need a different shaped lens? Do we need a different edge? Do we need a different material? Is it clinically significant? Is this especially significant in patients with large pupils? Do we need a bigger implant? Do we need a different shaped lens? Do we need a different edge? Do we need a different material? Robert G. Martin, MD Donald R. Sanders, MD, PhD
