Visual and Refractive Outcomes After Laser Blended Vision (PRESBYOND) in Patients With Myopia and Hyperopia

PURPOSE: To report visual and refractive outcomes after treatment with PRESBYOND Laser Blended Vision (Carl Zeiss Meditec AG) using non-linear aspheric profiles combined with micro-anisometropia laser in situ keratomileusis (LASIK) for the correction of myopic and hyperopic presbyopia. METHODS: This was a retrospective analysis of patients treated binocularly with PRESBYOND Laser Blended Vision using the MEL-90 excimer laser and VisuMax femtosecond laser (Carl Zeiss Meditec AG), and with at least 3-month postoperative data. Dominant eyes were targeted for plano and non-dominant eyes were targeted for myopia between -0.50 and -1.50 diopters (D). Manifest refraction, monocular and binocular uncorrected distance visual acuity (UDVA), monocular corrected distance visual acuity (CDVA), and binocular uncorrected near visual acuity were measured. RESULTS: The study included 232 eyes of 116 patients (170 hyperopic eyes and 62 myopic eyes). In the hyperopic group, mean spherical equivalent (SEQ) was reduced from +1.49 ± 0.67 D preoperatively to -0.06 ± 0.39 D postoperatively in dominant eyes, and to -1.29 ± 0.57 D in non-dominant eyes, with 96.5% of eyes within ±1.00 D of target. Binocularly, mean UDVA was -0.06 ± 0.08 logarithm of the minimum angle of resolution (logMAR) with 90.5% of patients 20/20 or better at distance and 98.8% reading N8 or better. In the myopic group, mean SEQ was reduced from -4.52 ± 2.28 D preoperatively to +0.12 ± 0.49 D postoperatively in dominant eyes and to -1.04 ± 0.54 D in non-dominant eyes, with 96.8% of eyes within ±1.00 D of target. Binocularly, mean UDVA was -0.07 ± 0.09 logMAR with 87.1% of patients 20/20 or better at distance and 87.1% reading N8 or better. CONCLUSIONS: PRESBYOND Laser Blended Vision was a safe and effective procedure for the treatment of myopic and hyperopic presbyopia.
