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

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.

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.

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.

PRESBYOND Laser Blended Vision was a safe and effective procedure for the treatment of myopic and hyperopic presbyopia.
