Evaluation of ChatGPT-4o, Claude 3.5 Sonnet, and Google Gemini 2.0 Flash as Patient Education Resources for Upper Blepharoplasty Patients.

Purpose: This study aimed to evaluate the effectiveness, accuracy, and readability of the leading large language models (LLMs) from 3 different companies, ChatGPT-4o, Claude 3.5 Sonnet, and Google Gemini 2.0 Flash, as patient education resources for upper blepharoplasty.

Methods: Twenty frequently asked questions about upper blepharoplasty were posed to the 3 LLMs. Two ophthalmologists recorded the responses to the questions and independently evaluated the accuracy of the LLMs using a 5-point Likert scale with scores ranging from 1 to 5. The readability of the analyzed texts was assessed using the SMOG index and the Coleman-Liau index.

Results: All models demonstrated high accuracy, with mean Likert scores exceeding 4.5. No statistically significant difference in Likert scores was observed among the 3 models (P=0.097). Claude 3.5 Sonnet generated the most complex responses (Coleman-Liau index: 17.34; SMOG index: 23.82 points), whereas Google Gemini 2.0 Flash produced the most comprehensible texts (Coleman-Liau index: 13.27; SMOG index: 15.04 points).

Conclusion: Large language models hold great promise as tools to educate patients about upper blepharoplasty. Future research should focus on simplifying language models without compromising accuracy, keeping models up-to-date, and minimizing bias to improve patient care and safety.
