Objective: In a prospektive international clinical study the AcuFocus ACI 7000 corneal implant is evaluated regarding its improvement of near reading ability in emmetropic presbyopic patients.
Methods: The corneal implant (which is only 10 microns thick) is placed under a corneal flap that can either be created with the microkeratome or the femtosecond-laser. It improves the depth of focus using small aperture optics and is implanted in the non-dominant eye only.
Results: In the part of the study with one year follow-up (Istanbul) uncorrected distance visual acuity was unchanged from pre-operative and uncorrected near VA improved significantly from pre-op Jg 6 to Jg 1+. Patients also experienced an improvement in intermediate VA and dependence from glasses for near and intermediate tasks was decreased.
In 3 other European study centers the 3-month-results were very similar to those observed in Istanbul.
The results of the 19 Salzburg patients - also regarding the Salzburg Reading Desk (SRD) will be presented. A single localized epithelial ingrowth could be healed by a partial flap lift, no other problems were observed in the Salzburg series.
Conclusions: The AcuFocus ACI 7000 corneal implant improves depth of focus and thereby increases reading ability and spectacle-independence significantly without seemingly compromising distance visual acuity. Long-term follow-up, however, is needed to come to final conclusions on this very promising method.
