Symfony Lens Refractive Target

[yulpaka]

I have cataract in one eye and have decided upon getting the Symfony lens. I know it isn't perfect, but I am attracted to the possibility of intermediate vision, as I am a developer and work on my laptop alot.

But I'm struggling to decide upon the refractive target I should ask for. My wish is that I would be able to see clearly from about 55cm (21.5 inch) onwards. I won't mind blurriness for anything nearer, but I want to see 'quite comfortably' at this range and onwards, even without the aid of my other untouched eye. I am struggling to decide between targeting for 0D, -0.5D, or maybe -0.25D...

Could anyone share their experience on target refraction for the symfony and their results? I know people's experiences vary alot, but I would be grateful for any suggestions or advice.

Thank you

Use the search feature and archives there are some quite lengthy discussions by people both very disappointed and some quite pleased with the Symfony.  Also the formula for determining IOL power and correlation with predicted and actual post operative refractive error do not approach plus or minus 0.25 diopters
