Two-Year Visual Outcomes And Satisfaction Following Presbyond Laser Blended Vision For Myopia Patients With Presbyopia

To evaluate the refractive and visual outcomes and satisfaction following PRESBYOND laser blended vision (LBV) for myopia patients with presbyopia, and to explore the key points of successful surgery. 

This retrospective study included 98 eyes of 49 patients (ranged from 39 to 52 years old) with myopia and astigmatism who underwent PRESBYOND LBV treatment between August 2021 and December 2023 at Beijing Tongren Hospital.

The patients were asked to attend a follow-up visit two years after surgery. Uncorrected distance visual acuity (UDVA), uncorrected intermediate visual acuity (UIVA), uncorrected near visual acuity (UNVA), subjective refraction, slip lamp, accommodative function, wavefront aberration, optical quality were measured. Questionnaires were completed to evaluate optical quality and satisfaction.

At the two-year follow up, mean UDVA, UNVA (log MAR) and SE for dominant and non-dominant eyes were 0.02±0.03, 0.10±0.05, -0.21±0.14 D; 0.13±0.03, 0.04±0.02, -0.60±0.25 D respectively. The binocular UDVA, UIVA and UNVA were -0.01±0.02, 0.06±0.03 and -0.01±0.01 (log MAR). PRA significantly decreased at 6 months (P<0.05) and recovered to preoperative level at 12 months postoperatively. The spherical aberration of dominant eyes was significantly higher than non-dominant eyes at the one-month visit and beyond (P<0.05). There was no significant difference in optical quality within the follow-ups. All the patients were satisfied with the clinical outcomes at the two-year visit.

PRESBYOND LBV could achieved safety, effective, and satisfactory visual outcomes for the treatment of presbyopia in myopia patients. Reasonable selection of surgical indications, sufficient tolerance testing, adequate communication, personalized surgical design, standardized implementation and meticulous postoperative care should be ensured to obtain satisfactory results.
