Assessing the visual and refractive outcomes of PRESBYOND laser blended vision treatment in myopic and hyperopic presbyopic patients in Western Australia
Abstract
Purpose: To evaluate the 6-month refractive and visual outcomes following PRESBYOND Laser Blended Vision (Carl Zeiss Meditec) treatment using non-linear aspheric micro-anisometropia laser in situ keratomileusis (LASIK) for the correction of myopic and hyperopic presbyopia. Methods: This was a retrospective, non-comparative study of 125 consecutive patients with a mean age of 53 ± 6 years (range: 42 to 70 years) who underwent LASIK-induced micro-anisometropia using the MEL 90 excimer laser and VISUMAX 800 femtosecond laser (Carl Zeiss Meditec AG). Preoperative and postoperative assessments of visual acuity and refractive error were conducted over a 6-month period. The target refraction was plano for the dominant eyes and between –1.00 and –1.75 diopters (D) for non-dominant eyes. Results: A total of 250 eyes (76 myopic and 174 hyperopic) were analyzed. Mean postoperative spherical equivalent re fraction was –0.03 ± 0.24 D (myopic) and –0.03 ± 0.34 D (hyperopic) for distance eyes and –1.51 ± 0.34 D (myopic) and –1.61 ± 0.34 D (hyperopic) for near eyes. Mean binocular UNVA was +0.08 ± 0.02 logarithm of the minimum angle of resolution (logMAR) (both myopic and hyperopic). Mean binocular UDVA was –0.05 ± 0.05 logMAR (myopic) and –0.06 ± 0.06 logMAR (hyperopic). Treatment demonstrated high refractive predictability and stability. A total of 94.4% (myopic and hyperopic) reported improved visual function and reduced spectacle dependence after initial treatment. The re-treatment rate was 5.3% in the myopic group and 12.6% in the hyperopic group. After re-treatment, 100% satisfaction was achieved in the hyperopic group and 98.8% in the myopic group. Conclusions: PRESBYOND laser treatment effectively improves both distance and near visual acuity in patients with presbyopia, with predictable refractive outcomes and high patient satisfaction. The non-linear aspheric micro-anisometropia protocol resulted in safe and effective visual outcomes in patients with both hyperopic and myopic presbyopia.
