3 Introduction and Basics: Bi-Focality Advantage/Comfort Clear foci; i.e. two sharp images on the retina Disadvantage/Discomfort Disturbing vision because of steps between zones Does typically not cover the whole distance range, especially not the intermediate part Pupil size critically dependent OR intermediate N Introduction and Basics: Q-value adjusted Advantage/Comfort Extended depth-of-focus The Q-value describes the shape between the cornea centre and periphery Disadvantage/Discomfort The Q-value is no predictor for visual performance Influenced by the change in radius of curvature (dioptric power); i.e. kind of unpredicted Unilateral (non-dominant eye) intermediate 3
4 Introduction and Basics: Multifocality Advantage/Comfort Covers the whole distance range due to different foci for distance, intermediate, Typically bilateral which keeps stereopsis Disadvantage/Discomfort Pupil size dependent Time of (neural) adaptation Possibly reduced contrast sensitivity OR intermediate N SCHWIND PresbyMAX vs. Competing Multifocal Technologies micro-monovision (ZEiSS) Aspheric (Nidek) PresbyMAX PresbyMAX µ-monovision Dominant Eye Non-dominant Eye intermediate 4

6 Alternative Presbyopic Solutions: Corneal Inlay Intracorneal inlays have been designed to create a small aperture effect or central steepening. The implant is intended to be placed intra-stromally either under a corneal flap or into a corneal pocket. Placement of the CI will be centered over the pupil, typically in the non-dominant eye. I. The AcuFocus Kamra corneal inlay (US): Ø 3.8 mm, 10 µm thick, central opening of Ø 1.6 mm, thousands of small laser openings for good corneal nutrition transport II. Flexivue Micro-Lens (NL): clear circular implant of Ø 1.5 mm, 10 µm thick in the periphery, increase of 24 to 40 µm to the centre, out of hydrogel (hydrophilic polymer) III. PresbyLens (US): clear circular implant of Ø 2 mm like a tiny contact lens out of hydrogel Advantage/Comfort Easily removed or replaced Increased depth-of-focus without tissue removal Disadvantage/Discomfort No refractive correction procedure, i.e. for emmetropes only Really fast recovery PresbyMAX - Unique Treatment Range Before PresbyMAX With PresbyMAX Limited treatment range e.g. only hyperopic patients e.g. only patients with minor astigmatism e.g. no presbyopia treatment of emmetropic or myopic patients e.g. only in combination with standard treatments e.g. only in combination with wavefront guided treatments Presbyopia software that offers a broad treatment spectrum for different indications: Treatment of emmetropic, myopic, hyperopic, and astigmatic eyes Correction of these visual defects can be performed as Aberration-Free or Customized treatments Any treatment method possible: PRK, TransPRK, LASEK, LASIK and FemtoLASIK 6

Trial with multifocal contact lenses (centre for, periphery for distance) could be done prior to surgery or easier, even if no influence/effect in multifocality (SphAb) can be demonstrated, simulate a vision of 1 to 2 lines less than BSCVA and ask for the postoperative acceptance (e.g. simulate distance refraction 0.25 to 0.50 D less than BCVA to the patient; simulate refraction with addition to less than BCVA to the patient). Most satisfied patients are hyperopes, then high astigmatics, then high myopes, then emmetropes, then low myopes. 10

Do both eyes simultaneously since otherwise the binocular vision will suffer from the multifocality on only 1 eye (anisometropia and aniseikonia). Perform treatments on the corneal vertex to reduce induction of coma aberrations disturbing vision at all distances. 11

15 Re-treatment Options PresbyMAX can be repeated if reading-spectacles demands renew. PresbyMAX can be repeated if reading quality (multifocality) is not sufficient but distance vision is satisfying. Aberration-Free treatment (with equal optical zone size to previous PresbyMAX procedure) can be performed on top for improved distance correction if reading quality (multifocality) is satisfying. PresbyMAX Reversal option with distance best corrected refraction included can be performed if the patient does not accept the PresbyMAX concept at all (too much compromise for the individual). Due to healing process and neuronal adaptation, a re-treatment procedure shall not be performed prior 6 months after surgery. PresbyMAX The Reversal Concept 15
16 PresbyMAX after Previous Refractive Surgery Previous Corneal Refractive Surgery (with the aim of emmetropic distance vision) Decision shall be equal to patients with virgin corneae. Futhermore, the SCHWIND decision tree for Aberration-Free, Corneal and Ocular Wavefront treatments might be considered Previous cataract surgery (natural lens exchange) Multifocal enhancement can be performed on the patient s cornea. Intraocular Surgery after PresbyMAX Aspheric IntraOcular Lenses: Properly calculated aspheric lenses (in the sense of aberration-neutral) after PresbyMAX provide the best quality of vision without compromising the already achieved pseudoaccommodation. (No decentration and tilting of the IOL and correct IOL power assumed) Spheric IntraOcular Lenses: Spheric Ienses induce positive spherical aberration and thus would remove in part or in total the already achieved pseudo-accommodation. Multifocal IntraOcular Lenses: Multifocal (refractive, diffractive, or accommodative) lenses induce negative spherical aberration and multiple foci and thus would enhance the already achieved pseudoaccommodation. But centration issues of the lenses become critical and may induce large amounts of coma from the misalignment between the PresbyMAX multifocal cornea and the multifocal IOL. 16
