Higher Order Aberration Following Implantation of 4 Foldable

Higher Order Aberration Following Implantation of 4 Foldable Lens Designs Robert G. Martin, MD Donald R. Sanders, MD, Ph. D

Study Objective v Objective Of The Study Was To Determine If Implantation Of Different Foldable Lens Designs Resulted In Different Amounts Of Higher Order Aberrations

Study Design v Patients Had Tracey VFA Performed On Eyes To Undergo Cataract Extraction v Patients Were Randomly Assigned To Receive 1 Of 4 Foldable Lens Designs v Tracey VFA Was

Pupil Size v All pre and postoperative measurements of higher order aberrations were done with a 4. 5 mm pupil size

Foldable Lens Designs v STAAR Collamer v STAAR Plate Haptic Silicone v ALCON SA-60 v AMO Sensar

Preoperative Total Higher Order (HO) Aberrations No Significant Difference Between IOLs

One-Week Postoperative Total Higher Order (HO) Aberrations Collamer significantly better than STAAR plate and Alcon SA-60 (p< 0. 005) N = 21 N = 24 N = 19 N = 16

Collamer IOL v Collamer Had Significantly Less HO Aberrations Than STAAR Plate And SA-60 (P 0. 005). v Difference With Sensar Was Not Significant.

Note v 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

Pre-op – Average H. O. Aberrations STAAR Collamer STAAR Plate Alcon SA-60 AMO Sensar

Postop – Average H. O. Aberrations STAAR Collamer STAAR Plate Alcon SA-60 AMO Sensar

Summary v Three Other Foldable Lenses Tested Had Between 55% and 117% More Higher Order Aberrations at 1 Week Postoperatively than the STAAR Collamer IOL

This Is A Study Of Optical Aberrations v Is it clinically significant? v Is this especially significant in patients with large pupils? v Do we need a bigger implant? v Do we need a different shaped lens? v Do we need a different Robert G. Martin, MD Donald R. Sanders, MD, Ph. Dedge?
