The personality factor in premium IOLs selection: quantifying Myers-Briggs personality types influence among cataract...

Phacoemulsification with intraocular lens (IOL) implantation is the standard treatment for cataracts. The surgeon's personality may influence IOL selection. Understanding whether Myers-Briggs Type Indicator (MBTI) personality profiles affect IOL selection accuracy and preferences can enhance patient satisfaction. Therefore, this retrospective single-center, cross-sectional study was conducted to evaluate the accuracy of IOL selection among cataract surgeons with different MBTI personality profiles and assess whether personality traits influence IOL preferences.

A total of 50 cataract surgeons with different personality profiles were involved to select IOL for 43 patients based on collected preoperative data. Surgeons' MBTI profiles were assessed, and their IOL selections were compared against clinical recommendations. Accuracy was analyzed across MBTI dichotomies (e.g., Extraversion/Introversion) and subtypes. Bland-Altman and consistency analyses evaluated preferences and agreement. Ocular biometric and comorbidity data were included.

No significant differences were found in IOL selection accuracy across the four MBTI dichotomous categories (P = 0.071, P = 0.178, P = 0.803, and P = 0.137, respectively). However, accuracy varied significantly across MBTI personality subtypes (P = 0.007). Consistency analysis revealed poor agreement across the four MBTI dimensions (Kappa = 0.012, Kappa = -0.013, Kappa = 0.001, and Kappa = 0.005, respectively). In contrast, Bland-Altman analysis indicated that Extraverted and Sensing surgeons showed a greater preference for multifocal and toric IOLs (all P < 0.05). Several ocular biometric parameters, ocular comorbidities, and systematic complications also significantly influenced the final choices (all P < 0.001).

While MBTI personality profiles influenced IOL selection preferences, they did not significantly impact the precision of IOL decision-making. Clinical practice guidelines for IOL selection should be validated further, and MBTI could serve as a predictor for understanding surgeons' IOL preferences. These findings suggest that IOL type preferences may vary among surgeons, which can help guide patients in choosing surgeons aligned with their specific needs.
