Abstract Details

Purpose:

To report 1year follow-up data related to safety and efficacy

Setting:

University-based refractive clinic

Methods:

Corneal Inlay (Presbia Flexivue Microlens&trade, Presbia Coöperatief U.A., Netherlands) was implanted in the non-dominant eye of emetropic presbyopic patients (0.75 SE 1.00SE) after the creation of a 300 microns depth stromal pocket using a femtosecond laser. Patients were followed according to a clinical protocol including refraction, anterior segment imaging analysis(Oculiser,Alcon) and wavefront evaluation (Nidek OPD Scan).

Results:

Thirty (30) patients have been enrolled to date in this ongoing study. The mean age is 50,83 years (range 45 to 60 years); 70% female, 30% male . The mean UNVA improved to jagger 1 in 90,5% of eyes treated with the Microlens. All eyes improved four lines in all date. The binocular UDVA is 20/20 in all cases. Patients reported near vision to be good or excellent in 86,4%. At the latest follow-up period, induction of corneal spherical aberration is statistically significant (as intended to improve near visual acuity).We had only one late complication and the implant was removed.

Conclusions:

In this data analysis, Presbia Flexivue Microlens&tradeprovided patients with improved near vision as a function of a myopic shift and negative spherical aberration. This intracorneal inlay appears to be an effective alternative to other procedures for the correction of presbyopia.
