Purpose

To report the visual outcomes of PRESBYOND Laser Blended Vision in a cohort refractive surgeons.

Setting

London Vision Clinic, London, UK

Methods

This was a retrospective analysis of 14 refractive surgeons who underwent PRESBYOND Laser Blended Vision using the MEL 80 or MEL 90 excimer laser and VisuMax femtosecond laser (both Carl Zeiss Meditec) between September 2011 to December 2022. The refractive target was plano for the distance eye and between -1.00 and -1.75 D for the near eye, as determined by the micro-anisometropia acceptance test. A further LASIK enhancement was performed for patients if improvement could be deemed to be achieved. Standard outcomes analysis was performed using the data at 12 months after all treatments.

Results

Mean age was 53±7 years (41 to 63 years). The attempted SEQ was -4.88 to +3.00 D (-0.53±2.55 D). Cylinder was 0.00 to -1.25 D (-0.52±0.31 D). Preoperative CDVA was 20/20 or better in 100% and 20/16 or better in 75% of eyes. An enhancement was performed for 2 eyes (7.1%) of 2 patients (14.3%). Final outcome after PRESBYOND including enhancements provided binocular UDVA of 20/20 or better in 100% and 20/16 or better in 83% of patients. Binocular UNVA was J2 or better in 90% and J5 or better in 100% of patients. Postoperative SEQ was within ±0.50 D in 85% and ±1.00 D in 88% of eyes. Postoperative cylinder was within ±0.50 D in 93% and ±1.00 D in 100% of eyes. There was 1 line loss of CDVA in 27% of eyes, and no eyes lost 2 or more lines CDVA.

Conclusions

Refractive surgeons operate in a visually challenging environment, PRESBYOND Laser Blended Vision LASIK provides an effective method of correction for refractive surgeons by providing clear and continuous vision for tasks at distance, intermediate and near.
