Abstract Details

Purpose:

To evaluate impact of personality type of patients on patient-reported quality of vision post refractive surgery.

Setting:

Narayana Nethralaya Bengaluru India

Methods:

200 myopes visiting our refractive department were administered the validated Eysenck’s Personality inventory (EPI) questionnaire before surgery. EPI questionnaire classifies patients as sanguine(S), phlegmatic(P), melancholic(M) or choleric(C) personality traits. Six months post-surgery, these patients underwent ray-tracing aberrometry and orthoptic evaluation apart from distance vision assessment. QIRC (Quality of life impact on refractive correction) questionnaire was filled by these patients to assess the quality of life as a numeric score.

Results:

All patients had an uncorrected distance visual acuity of 20/20 post-operatively. Based on EPI, there were 87 phlegmatic, 57 sanguine, 43 melancholic and 13 choleric patients. Ray-tracing aberrometry derived median(95% CI) modulation transfer function for similar pupil zone was 0.4(0.15,0.45), 0.29 (0.14,0.34), 0.23 (0.1,0.32) and 0.24 (0.14, 0.33) in C, M, P and S groups respectively and there was no statistical difference (p=0.18). Near point of accommodation and convergence was similar across the groups. Mean(SD) of numeric QIRC scores were 39.0(4.70), 45.08(2.80), 53.86(3.03) and 52.0 (2.82) in C, M, P and S groups respectively and they were significantly different (p<0.05). C group patients had significantly higher number of outpatient visits than M, P and S groups.

Conclusions:

With similar quantity and aberrometric quality of vision post-refractive surgery, choleric group had significantly poorer quality of life related to vision. Utilisation of EPI questionnaire as a pre-operative tool can help in better pre-operative counselling or deferring surgery in the choleric subset of patients.
