Outcomes Of Presbyond In A Population Of 1,544 Myopic Patients

To report the refractive and visual outcomes of PRESBYOND Laser Blended Vision in a large population of myopic patients with presbyopia.

London Vision Clinic, London, UK

This was a retrospective analysis of myopic patients with presbyopia who underwent PRESBYOND using the MEL 80 or MEL 90 excimer laser and VisuMax femtosecond laser (both Carl Zeiss Meditec) between October 2009 to August 2023. The refractive target was plano for the distance eye and between -0.50 and -1.75 D for the near eye, as determined by the micro-anisometropia acceptance test. Inclusion criteria was patients with bilateral myopic manifest refraction, preoperative CDVA 20/20 or better in both eyes, and underwent PRESBYOND. Standard outcomes analysis was performed using the data at 12 months or at the last visit if a retreatment was performed earlier. Patients with no data at 12 months were lost to follow up and excluded.

A total of 1,544 patients (3,088 eyes) were included. Mean age was 50±6 years (range: 40 to 77 years). Mean attempted SEQ was -2.47±1.71 D (range: -11.13 to +1.00 D). Mean cylinder treated was -0.88±0.70 D (range: 0.00 to -5.50 D). Preoperative CDVA was 20/20 or better in 100% in all eyes. Binocular UDVA was 20/20 or better in 92% and 20/25 or better in 97% of patients. Binocular UNVA was J2 or better in 90% and J5 or better in 99% of patients. Postop SEQ relative to target was +0.04±0.36 (range: -3.50 to +1.50 D), within ±0.50 D in 89% and ±1.00 D in 99% of eyes. There was 1 line loss of CDVA in 6% and 2 lines loss in 0.1% of eyes. There was a statistically significant improvement in contrast sensitivity at 3, 6, 12, and 18 cpd (P<.001).

PRESBYOND Laser Blended Vision LASIK achieved excellent binocular vision and distance and near for myopic patients with presbyopia. Safety in terms of CDVA and contrast sensitivity was also demonstrated. Further improvement in visual outcomes can be achieved with retreatment (not reported here).
