Visual and Refractive Outcomes After Laser Blended Vision (PRESBYOND) in Patients With Myopia and Hyperopia

Area of Science:

• Ophthalmology
• Refractive Surgery
• Corneal Surgery

Background:

• Presbyopia, an age-related condition, affects near vision and necessitates reading glasses or multifocal contact lenses.
• Laser vision correction aims to provide spectacle independence for various refractive errors.

Purpose of the Study:

• To evaluate visual and refractive outcomes of PRESBYOND Laser Blended Vision for myopic and hyperopic presbyopia.
• Assess the efficacy of non-linear aspheric profiles and micro-anisometropia LASIK for presbyopia correction.

Main Methods:

• Retrospective analysis of 116 patients (232 eyes) treated with PRESBYOND Laser Blended Vision.
• Dominant eyes targeted for plano, non-dominant for myopia (-0.50 to -1.50 D).
• Postoperative data at least 3 months, including visual acuity and refraction.

Main Results:

• Hyperopic group: Mean SEQ improved from +1.49 D to -0.06 D (dominant) and -1.29 D (non-dominant).
• Myopic group: Mean SEQ improved from -4.52 D to +0.12 D (dominant) and -1.04 D (non-dominant).
• Binocular UDVA: 90.5% of hyperopic and 87.1% of myopic patients achieved 20/20 or better distance vision; near vision was also significantly improved.

Conclusions:

• PRESBYOND Laser Blended Vision is a safe and effective treatment for both myopic and hyperopic presbyopia.
• The procedure demonstrates high patient satisfaction with improved distance and near visual acuity.
