Drs. Elizabeth Yeu and William Wiley explore the fundamentals of small-aperture optics for presbyopia patients, focusing on the impact of pupil size, aperture size, refractive error, and residual accommodation on surgery and visual outcomes. Drs. Yeu and Wiley emphasize the importance of considering these factors during refractive evaluations and pharmacological and small-aperture optics interventions. This dialogue builds upon a conversation involving 12 optometrists and ophthalmologists previously published in a collaborative CE/CME supplement to CRST and Modern Optometry in April 2023.
