Advantageous effect of pupil dilation on the quality of optical biometry axial length measurement in individuals with dense cataract.

Pharmacologic pupil dilation improved the quality of SS-OCT biometrically measured AL in patients with low-quality AL measurement due to dense cataract. These results could potentially improve postoperative refractive outcomes after cataract surgery and reduce the need of additional AL measurements by more complicated alternative means in this group.
