Abstract Details

Purpose:

To present the visual outcomes and safety after implantation of the Presbia Flexivue Microlens Refractive intracorneal Inlay for the improvement of near vision in emmetropic eyes with presbyopia, and to evaluate the visual outcomes, safety and the interaction of the inlay with cataract surgery.

Setting:

Prospective non-comparative interventional clinical study in 70 emmetropic presbyopes with inlay implantation, and case series of 3 presbyopes with cataract surgery and inlay implantation. For the implantation, a corneal pocket was created using femtosecond laser at the Institute of Vision and Optics of the University of Crete in Greece.

Methods:

70 presbyopic patients (Group 1) were implanted with the Presbia Flexivue Microlens. In addition, 2 presbyopic patients underwent implantation of the inlay post-cataract surgery, and 1 patient underwent implantation prior to cataract surgery (Group 2). All inlays were implanted in the corneal stroma of the non-dominant eye. Mean age was 52.3 (± 3.3) years (range: from 47 to 58). Follow-up was 24 months for Group 1 and was 12 months for Group 2.

Results:

Group 1 had an uncorrected near visual acuity of more than 20/25 in 70% and more than 20/40 in 99% of the patients 24 months postoperative. Binocular uncorrected distance visual acuity was not affected significantly. One inlay had to be explanted due to stereoptic poor adaptation to monovision. In Group 2, all patients achieved a binocular uncorrected visual acuity 20/20 for distance and for near. The preoperative and operative workup of the patient undergoing cataract surgery after inlay implantation was not affected by the presence of the inlay. No additional adverse events were reported.

Conclusions:

The Presbia Flexivue Microlens Intracorneal refractive inlay for improvement of near vision for presbyopia is an effective and potentially reversible method for the corneal compensation of presbyopia in emmetropic presbyopes and in presbyopes that have had cataract surgery. Seems that the inlay can also be implanted prior to cataract surgery without inhibiting visualization of the anterior chamber.
