search information related to IOL, biometry, corneal topography, etc.

This article provides insights into the different modern IOL power calculation formulas like the Barrett Universal, Kane and EVO formula

The following table will help in the choice of EDOF IOL based on spherical aberration of the cornea of the patient and the induced spherical aberration by the IOL

This article provides an understanding of circle of least confusion or best focus in presence of spherical aberration and what kind of spherical aberration may provide a better depth of focus

finding the cut off value for mesopic pupil size may be important for clinicians to ensure that patients have a good distance vision even in low light

How does the Panoptix Pro utilize more light and reduce light scatter.

Why some patients may not be happy with an EDOF IOL.

Explains how does the Tecnis PureSee IOL provide depth of focus and intermediate vision to patients.

Difference between the Snellen chart and the ETDRS chart based on logmar

standard way of diffractive trifocal IOL manufacturing has been to use the 0 order for distance, & the +1 & +2 orders intermediate & near

Since the launch of the RayOne Galaxy lens, there has been a significant amount of attention focused on spiral optics and how such design provides multiple focal points to provide depth of vision to patients. The adoption of spiral optics to provide such multifocality in IOLs or contact lenses is new, and not many literature is available that would help a layman like myself, to comprehend. So here I set out to reflect what I have understood whatever reading material is availa

This is a video explanation on negative dysphotopsia, its causes, symptoms, and treatment options.
