  1. Examples of Accommodation Evaluation with the Tracey 3-D Difference Maps Tracey Technologies, Corp.

  2. Normal Accommodation – 30 Y/O Refraction Map DISTANCE NEAR NEAR DIFFERENCE

  3. Normal Accommodation 3D Refraction Map (Tilted) DISTANCE NEAR DIFFERENCE

  4. Normal Accommodation 3D Refraction Map (Vertical) DISTANCE NEAR DIFFERENCE

  5. Normal Accommodation 3D Refraction Map (Vertical) DISTANCE Hyperopia Mean = +0.4D 1.2D Refractive Range Myopia

  6. Normal Accommodation 3D Refraction Map (Vertical) NEAR Mean = -4.2D 3.5D Refractive Range

  7. Normal Accommodation 3D Refraction Map (Vertical) DIFFERENCE Mean = -4.75D 2.4D Refractive Range

  8. Observations in Normal Accommodation and Near Point Focus • Refraction shifts to More Myopia as Accommodation is defined as a purely Spherical offset • Refractive Range Increases (i.e. More Depth of Field – Psuedo Accommodation)

  9. Monofocal IOL 3D Refraction Map (Vertical) DISTANCE NEAR DIFFERENCE

  10. Monofocal IOL 3D Refraction Map (Vertical) DIFFERENCE No Refractive Difference 0.6D Refractive Range

  11. MONOFOCALPSF @ 33 cm. ACCOMMODATIVE EFFORT DISTANCE NO DIFFERENCE IN PSF

  12. MONOFOCALImage SimulationView @ 33 cm. ACCOMMODATIVE EFFORT DISTANCE NO DIFFERENCE IN IMAGE

  14. Acc. IOL in Other Eye 3D Refraction Map DISTANCE +2.8D 4.1D Refractive Range Mean = +1.6D -1.3D

  15. Acc. IOL in Other Eye 3D Refraction Map NEAR +3.8D Mean = +1.1D 8.6D Refractive Range -4.8D

  16. Acc. IOL in Other Eye 3D Refraction Map DIFFERENCE +1.1D 5.5D Refractive Range Mean = -0.4D -4.5D
