Abstract Details

Purpose:

This prospective study set out to study the safety and efficacy of human corneal collagen inlays for the treatment of presbyopia in emmetropic patients. 45 patients from this site (1 site out of 5 European sites) are included in this analysis.

Setting:

The Wellington Eye Clinic, Dublin, Ireland

Methods:

45 patients were treated at this site by implanting a 2.65mm 22-micron thick corneal collagen inlay under a 110-micron LASIK flap for the correction of presbyopia in the non-dominant eye. Visual and refractive results were analysed as well as topographic and anterior segment OCT findings. Wavefront analysis was also performed and bio-compatibility was monitored.

Results:

The average preoperative unaided reading vision was N12 and the average unaided reading vision at 6-months is N4.9. The binocular UDVA is unchanged while the average UDVA in the implanted eye is 0.75. The inlay is very well tolerated from a bio-compatibility point of view. Two eyes were explanted due to patient dissatisfaction in terms of ocular balance, without any side-effects.

Conclusions:

Corneal human collagen implants from Allotex worked very well for improving uncorrected near vision, having minimal impact on the UDVA in the implanted eye and no impact on binocular UDVA. The two eyes that were explanted had no sequelae from the surgery or explant whatsoever. The Allotex inlay is a safe and effective corneal inlay and solution for presbyopia correction in carefully selected candidates.
