Objective:

To discuss the differences and clinical significance of aspheric and extended depth of focus (EDOF) multifocal contact lens designs for presbyopia.

Key Findings:

• Aspheric multifocal lenses provide simultaneous optics for distance and near vision but may cause glare and halos, particularly in higher add powers.
• EDOF lenses offer a continuous focal range, reducing glare and halos but may compromise retinal image quality, especially for higher degrees of presbyopia.
• Both lens types can leverage the eye's natural higher-order aberrations to enhance vision, but practitioners should consider individual patient profiles.

Interpretation:

The choice between aspheric and EDOF lenses should be based on individual patient needs, considering both the benefits and limitations of each design, and how to assess these needs effectively.

Limitations:

• Aspheric lenses may lead to symptomatic glare and halos, especially at higher add powers, which should be monitored.
• EDOF lenses may not provide sufficient near power for higher degrees of presbyopia, necessitating careful patient evaluation.

Conclusion:

Understanding the functional differences and clinical implications of aspheric and EDOF multifocal lenses can empower eye care providers to recommend optimal options for presbyopic patients, highlighting the need for ongoing education in lens technology.
