IOL surface and bulk inhomogeneities have the potential to change the lens optical clarity and present as surface haze, subsurface nanoglistenings, or glistenings

Advancements in analog visualization technology have reached a plateau; Digital visualization provides several advantages that can be applied to multiple medical specialties that could not be realized with analog technologies;…

OVDs are essential surgical aids that create and maintain space, coat surfaces, protect ocular tissues, and facilitate the surgical procedure^1,2

Alcon WaveLight^® Topography-Guided LASIK and Zeiss small-incision lenticule extraction (SMILE^) treatments are fundamentally very different corneal refractive procedures.

Artificial tears aim to replicate the natural tears’ composition and physical properties.

Posterior corneal astigmatism (PCA) is important in the selection of the toric IOL power

Depth of focus extension elongates the focal region to provide a continuous range of vision from distance to intermediate, with some functional performance at near.

Astigmatism occurs when light entering the eye does not converge at a single focal point in the back of the eye, but instead focuses at two different locations.

Today’s SS-OCT Biometers employ two methods to measure the axial length: Sum-of Segments using individual refractive indices or a Mean Group Refractive Index
