Objective:
To analyze sex differences in preferred contact lens power under-correction among patients aged 20 to 79 years, highlighting the clinical significance of these differences.
Approach:
- Women aged 40 to 59 years preferred greater under-correction (0.41 diopters) compared to men (0.34 diopters), which may affect visual comfort.
- Near addition requirements were similar between sexes across all age groups, indicating consistent visual needs.
- Men had greater astigmatic error and anisometropia than women in the 40 to 59 age group, which could influence lens selection.
- Ocular surface parameters were generally worse in women, except for the Schirmer test, suggesting a need for targeted interventions.
- Retrospective design and single clinic population may limit generalizability, potentially affecting the applicability of findings.
- Lack of objective measurements of accommodation and lifestyle factors may overlook important influences on visual demands.
- Detection bias due to unequal sample sizes between sexes could skew results, although the sample size for men remains sufficient for statistical analysis.
Key Findings:
Interpretation:
The study indicates significant sex differences in preferred contact lens power under-correction, particularly in women aged 40 to 59 years, suggesting a need for tailored approaches in contact lens prescriptions to enhance patient satisfaction.
Limitations:
Conclusion:
The findings highlight that women prefer greater under-correction in contact lenses than men, particularly in the 40 to 59 age group, which may influence clinical practices in optometry and necessitate individualized patient care.
