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"
