PurposeHere, we report the results of a 3-year follow-up analysis of the outcomes of the Flexivue Microlens corneal inlay.PatientsNon-dominant eyes (n=31) of emmetropic presbyopic patients (spherical equivalent: −0.5 to 1.00 dioptre).MethodsA Flexivue Microlens corneal inlay was implanted after the creation of a 300 μm deep stromal pocket using a femtosecond laser. Patients were followed up according to a clinical protocol involving refraction, anterior segment imaging analysis (Oculyser), optical quality analysis (OPD-Scan), monocular binocular uncorrected and corrected visual acuity tests, contrast sensitivity measurements (photopic and mesopic), satisfaction questionnaire results and adverse event reporting.ResultsThirty patients were examined at the 3-year follow-up in this ongoing study. The mean uncorrected near visual acuity improved to Jaeger 1 in 76.9% of eyes treated with the inlays (vs 87.1% at the 1-year follow-up). All eyes improved four lines in all visits, except for four patients for whom the inlay was explanted. Patients reported that their near vision was good or excellent in 73.3% of cases (vs 90.3% in the first year). The UDVA remained stable over time. Three patients were explanted due to blurred vision for near-point and far-point distances. One patient developed a superficial corneal ulcer after 20 months. Two patients underwent cataract removal. Four patients underwent inlay exchange to increase near power correction.ConclusionsThe Presbia Flexivue Microlens provided presbyopia treatment by improving near vision. Manageable complications may occur over the long term.Clinical trial registration numberU1111-1185-5684 and 0310451200000550.

This paper is to show that the increase in the convexity of the lens, when accommodated for near vision, is effected by compression of the equator of the lens by an erectile cushion composed of the ciliary processes turgid with blood, the ciliary muscle being the motor agent; also that the iris aids accommodation by increasing its rapidity, but that accommodation of vision can be effected slowly without the assistance of the iris. The author states that, by dissection of human eyes, he has determined the existence of an erectile mass attached to the interior surface of the ciliary muscle from which the ciliary processes proceed, and that in dissections of injected specimens the vessels of the ciliary processes and of the erectile mass can be seen to pass through and between the fibres of the ciliary muscle near to the apex of that muscle.
