Objective:

To evaluate whether a simple preoperative vision test can predict which patients with presbyopia will successfully adapt to laser blended vision.

Approach:

• Preoperative Testing: A standard phoropter-based assessment was used to maximize binocular distance vision, followed by defocusing one eye to simulate short-sightedness. Patients rated their vision quality, and those maintaining at least 80% vision quality with one eye defocused we…

Key Findings:

• 1.66% of patients were identified as unsuitable for treatment based on preoperative testing.
• 96.9% of patients who proceeded to surgery successfully adapted to laser blended vision.
• The assessment demonstrated high predictive value for tolerance of blended vision.

Limitations:

• The study was limited to a specific patient population and may not be generalizable.
• The assessment relies on subjective patient ratings, which could introduce variability.
