§01Overview

Brief overview

This study evaluated four pretrained convolutional neural network (CNN) facial-analysis platforms — Face++, Betaface, Facelytics, and Everypixel — to quantify perceived age reduction after brow lift and blepharoplasty using standardized pre- and postoperative facial photographs from 153 patients at a single cosmetic surgery practice. Across all platforms, mean age-estimation error was 10.6%, with algorithms generally underestimating true age. AI analysis found an average perceived age reduction of 1.03 years after periorbital rejuvenation surgery, with brow lift independently associated with the greatest reduction (1.43 years). The study used proprietary third-party CNN systems rather than a newly trained model. No code, weights, external validation, regulatory clearance, or clinical deployment were reported.

§02Performance
Headline performance

Platforms generally underestimated true age; preoperative percentage errors ranged 4–18%.

Full metrics — as reported
Platforms generally underestimated true age; preoperative percentage errors ranged 4–18%.
Overall AI-estimated age reduction: −1.03 years (P < .001).
Brow lift independently associated with −1.43 years (P = .031); blepharoplasty alone not significant.

Why this score?

The APPRAISE-AI tool grades AI/ML medical studies across 24 items in 6 subdomains, scored independently by two reviewers. The total reflects the methodological transparency of the publication — not the underlying clinical value of the model.

How to read this: high scores in clinical relevance and reporting with low scores in methodological conduct, robustness, or reproducibility is the dominant pattern in ophthalmic AI today.

Quality bands: Low <40 · Moderate 40–59 · High 60–79 · Very High 80+. Most published ophthalmic AI sits in the Low–Moderate band; studies that break into High typically combine multi-center datasets, prospective evaluation, and open-source release.
