Objective:

To provide an overview of various corneal GP lens designs and their appropriate applications based on corneal characteristics.

Key Findings:

• Spherical GPs are best for low-toricity corneas with minimal residual astigmatism.
• Front-surface toric designs can correct residual astigmatism but may have stability issues.
• Bitoric and back-surface toric lenses provide stable vision for higher astigmatism.
• Aspheric lenses improve centration for borderline toricity cases.
• Reverse geometry lenses are effective for specific post-surgical corneal shapes.

Interpretation:

Corneal GP lenses offer diverse designs tailored to specific corneal shapes and vision correction needs, with each design having unique advantages and considerations.

Limitations:

• The article does not provide empirical data or studies to support the effectiveness of each lens design.
• Potential for variability in individual patient responses to different lens designs is not addressed.

Conclusion:

Corneal GPs remain a valuable option in contact lens fitting, complementing the growing popularity of scleral lenses.
