Abstract Details


To report 6 month follow-up data related to safety and efficacy


University-based refractive clinic


Inlay (Presbia Flexivue Microlens™, Presbia Coöperatief U.A., Netherlands) was implanted in the non-dominant eye of presbyopic patients 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 and wavefront evaluation.


Twenty-two (22) patients have been enrolled to date in this ongoing study. The mean age is 50,3 years (range 45 to 60 years); 77,3 % female, 22.7% male . The mean UNVA improved four lines in 73% of eyes treated with the Microlens, and three lines in all eyes to date. The binocular UDVA is 20/20 in all cases. Half of the patients reported vision to be good or excellent. At the latest follow-up period (3 months postoperatively), induction of corneal spherical aberration is statistically significant (as intended to improve near visual acuity). No intraoperative or postoperative complications are reported.


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.
