Safety and Efficacy of an Intrastromal Transform Corneal Allograft (TCA) for Presbyopia Correction - Long Term Follow-up

The participants will undergo the following assessments: 1. Pupil size measurement 2. Manifest refraction (no autorefraction) 3. Monocular in both eyes and binocular uncorrected visual acuity (photopic): * Distance (4 m) * Intermediate (80 cm) * Near (40 cm) 4. Monocular best corrected visual acuity (photopic): * Distance (4 m) * Near (40 cm) * Distance-corrected near (40 cm) 5. Monocular and binocular mesopic (with and without glare) and photopic (without glare) contrast sensitivity testing (subgroup) 6. Slit lamp examination 7. Tear breakup time 8. Placido Corneal topography, keratometry and pachymetry 9. Optical coherence tomography including epithelium mapping (subgroup) 10. Applanation intraocular pressure 11. Cycloplegic refraction 12. Dilated fundus examination 13. Wavefront aberrometry (subgroup) 14. Adverse events
