The relation of astigmatism and hyperopia (more effective plus)
Journal of the American Optometric Association
|June 1, 1985
Summary
High astigmatism is clinically and theoretically linked to hyperopia. This review of 298 cases confirms a relationship between significant astigmatism and increased plus power in refractive errors.
Area of Science:
- Ophthalmology
- Optometry
- Refractive Error Research
Background:
- High astigmatism presents unique challenges in vision correction.
- Understanding its relationship with other refractive errors is crucial for clinical practice.
Purpose of the Study:
- To investigate the clinical and theoretical association between high astigmatism and hyperopia.
- To analyze the correlation between high astigmatic refractive errors and the degree of hyperopia.
Main Methods:
- Review of 298 cases with high astigmatic refractive errors.
- Analysis of clinical data to establish relationships between astigmatism and hyperopia.
Main Results:
- All analytical methods confirmed a positive correlation.
- A significant relationship was found between high astigmatism and greater plus power (hyperopia).
Conclusions:
- High astigmatism and hyperopia are demonstrably related.
- Findings support the clinical understanding of complex refractive error interactions.
