Here is a tool that will help you to analyse the root cause of refractive surprise and what you could do for the second eye by taking into account the refractive surprise of the first eye.

The clinical dilemma Imagine planning an EDOF or diffractive multifocal IOL in a patient with borderline corneal astigmatism. The astigmatism is too low to justify a toric IOL Yet high enough to potentially degrade visual quality, especially with premium optics The real-world scenario In this case in image 1 below Keratometry shows ~0.81 D astigmatism The IOL of choice highlighted is 26.50 against a spherical equivalent (SE) of -.11 with the SRK T formula. This falls into a

This tool helps you to optimize/personalize a-constant for better refractive outcomes.

Recently, Filomena and co-authors ( https://doi.org/10.1097/j.jcrs.0000000000001502 ) presented evidence based scientific classification of partial and full range vision lenses. Based on their classification, I could summarize the following: a) IOLs that provide more than 2.3 diopter of pseudo-accommodation at .2 log mar (6/9.5 or 20/32) in the defocus curve can be classified as full range of vision IOLs b) IOLs that provide less than 2.3 diopter of pseudo-accommodation at

Objective: This tool helps you to find following things: What is the true size of the diameter of the central bull's eye of the diffractive multifocal IOL Where is the light passing through the bull's eye dedicated to How to Use: A. Enter the add power of the diffractive IOL B. Enter the wavelength of light ( usually 550 or 555 nm of light is the industry standard) Example: A diffractive multifocal IOL of 3.75 add power claiming its central bull's eye zone to be .769 should d

This tool helps you to calculate the lens power based on thick lens formula. It also helps locate principal plane in the optic

This tool will help you to use Haigis L formula for post lasik patients. As first step it helps you to convert K readings.

This calculator helps you to predict near add power in corneal or spectacle plane based on patient details and multifocal IOL add in lens

This calculator gives you an idea about post operative ACD or ELP by predicting it based on preoperatve ACD with optional lens thickness....

How CMAL may be the answer to traditional optical biometry measuring axial length on the basis of group refractive index

f you had a more than .50 diopter of refractive error in the first eye, here is a calculator to to consider IOL power for the second eye ba
