Optical Analysis of Eyes Implanted With Cornea Inlays for Correction of Presbyopia
Narrative Responses:
Purpose
To report 1year follow-up data related to safety and efficacy.
Methods
Corneal Inlay (Presbia Flexivue Microlens, Presbia) 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
Twenty-two (22) patients have been enrolled to date in this ongoing study. The mean age is 49,16 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 76,2%. At the latest follow-up period, induction of corneal spherical aberration is statistically significant (as intended to improve near visual acuity). No intraoperative or postoperative complications are reported.
Conclusion
In this preliminary data analysis, Presbia Flexivue Microlens provided 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.
