Evaluating the Efficacy and Safety of the LASIK Nonlinear Aspheric Micro-Monovision Surgery (Laser Blended Vision Surgery) in Correcting Presbyopia Among the Saudi Population.

BACKGROUND/

OBJECTIVES

To evaluate the monocular and binocular visual outcomes for patients who underwent PRESBYOND Laser Blended Vision (LBV) surgery.

METHODS

A total of 46 patients participated in this study (mean age 47.5 yrs ± 4.7) with various refractive errors. Patients were treated using the MEL 90 excimer laser to correct their refractive errors. The patients were asked to attend follow-up sessions at intervals of 1, 3, and 6 months. A self-developed binary (Yes/No) satisfaction survey was then conducted at the end of the 6-month visit.

RESULTS

The mean preoperative spherical equivalent for the distance eyes was -0.42 ± 1.53, and for the near eyes was -0.4 ± 1.76. The mean logMAR for the uncorrected distance visual acuity after treatment and follow-up at one month, three months, and six months was 0.016, 0.037, and 0.028 (20/20 to 20/22 range), respectively. After treatment, 81% of patients achieved 20/22.5 vision or better, and 94% achieved 20/25 vision or better. For near vision, 100% of patients reached J2 print. After treatment, 97% of patients achieved 20/25 or better at distance and J2 or better at near. Patient satisfaction was 92%, with only 8% of patients reporting dissatisfaction.

CONCLUSIONS

This protocol has demonstrated stable, well-tolerated, effective, and acceptable results in patients with presbyopia. The safety and efficacy of the procedure were demonstrated, with strong outcomes.
