Three-month outcomes of PresbyEDOF: A retrospective case study evaluating a laser-based corneal solution for presbyopia correction

PURPOSE: To evaluate the safety, efficacy, and refractive predictability of PresbyEDOF, an individualized corneal laser technique for presbyopia correction. METHODS: In this retrospective, single-center case series, 114 eyes of 57 patients (mean age 54 ± 4.7 years) were treated with PresbyEDOF using the SCHWIND AMARIS 1050RS. The treatment induced approximately 1.5 D of extended depth of focus in both the near-dominant and far-dominant eye, with a planned anisometropia of 1.5 D. Primary outcomes at 3 months included binocular uncorrected distance visual acuity (UDVA), uncorrected near visual acuity (UNVA), refractive predictability, change in corrected distance visual acuity (CDVA), residual astigmatism, retreatment rate, and visual disturbances. RESULTS: Binocular UDVA of 0.0 logMAR was achieved in 92% of patients. UNVA of ≥0.0 logMAR was achieved in 40% and ≥0.2 logMAR in 93% of patients. CDVA remained unchanged in 38% of eyes, decreased by one line in 27%, and improved by one line in 35%. Residual astigmatism >0.5 D occurred in 4% of eyes. Retreatment was required in three patients (5.3%), including two cases retargeted for improved intermediate vision. No intraoperative complications, ectasia, or infections were observed. All patients reported improved visual quality, with photic phenomena described as rare and transient. CONCLUSIONS: PresbyEDOF demonstrated favorable distance and near visual outcomes, high visual quality, and low residual astigmatism at 3 months. The technique appears to be a safe and effective corneal approach for presbyopia correction, warranting further prospective studies with longer follow-up.
