Purpose

To evaluate the initial clinical outcomes of presbyopia correction using a sterile corneal allograft inlay combined with LASIK for simultaneous ametropia correction.

Setting

Laser Eye Clinic Vienna

Methods

Interventional case series of 8 eyes undergoing combined femtosecond LASIK and stromal allograft implantation. A LASIK flap was created using the SCHWIND ATOS femtosecond laser, followed by excimer ablation with the SCHWIND AMARIS to correct manifest refractive error. The sterile allograft lenticule was implanted stromally prior to flap repositioning. Pre- and postoperative assessments included binocular uncorrected distance visual acuity (UDVA), binocular uncorrected near visual acuity (UNVA), manifest refraction, and anterior segment OCT.

Results

Binocular UDVA improved in all eyes due to refractive correction. Postoperatively, all patients achieved binocular UNVA of 20/40 or better. Anterior segment OCT confirmed proper graft positioning and interface clarity without flap- or graft-related complications. Optimal refractive planning required a mild hyperopic target in the non-dominant eye and plano in the dominant eye to achieve balanced binocular distance and near performance. Patients reported high functional satisfaction.

Conclusions

Combined LASIK and sterile allograft corneal inlay implantation is feasible for treating presbyopia in patients with low ametropia. The procedure allows simultaneous refractive correction and near vision enhancement while preserving binocular distance vision. This tissue-based approach expands the indication of allograft presbyopia correction beyond emmetropic patients and offers a potentially reversible surgical option.
