Preparing for 2nd Cataract Surgery (Synergy), Need help better understanding the IOL Master Numbers.

Well, finally went in for my cataract eye exam for my 2nd cataract surgery.

When I did my first cataract surgery 4 years ago I had studied up, but after coming to this forum and doing more research I know just how little I knew back then and how little I still know.

They had actual put my records into storage which they are going to dig out. I want to use the old numbers, because my cataract is so bad I worry how accurate the new numbers are. I could not even make out the 20/200 Big Letters.

They pulled out the old IOLMaster, but did both the Laser and Ultrasound measurements. They actual take a pencil like device with a blue light and touch your eye. Not sure how accurate that is when they might indent when pushing it in.

Anyone with knowledge about the difference in readings these 2 methods produce. It seems like the Axial Length AL was different from the 2 methods. Also should the right and left eye AL be close?

The reading for Cyl was .78D. Am I correct in that is the Astigmatism? I hope that do not mean I need a toric IOL.

The readout provides A Cont, which I think are diopter IOL power for various monofocal IOL. They just used the Tecnics Monofocal for my numbers. I guess same manufacture and IOL structure is the same.

From that chart I was a 13.5 to get -0.19D or Plano (I think) or 13.0 to get to .11. Being I am planning on Synergy maybe safer to go with the 13.0.

I am not sure how that 13.0 relates to refractive error as it seems huge to me and very nearsighted.

Not sure how it compares but my contact prescription for that lens was power -4.5.

Any suggestions on what other numbers to read that are important from the readout? There are numbers like K1 and K2 and so forth.

Next topic cost. I was told it was $2300 for the Synergy. I have no idea what that lens should cost. Does that sound about right? It seem a bit unfair that insurance fully pays for a monofocal, yet you must pay full cost for the premium. Seems to me it should be an upgrade only cost of whatever the cost difference is.

Finally he has only implanted 5 people so far the Synergy IOL, but says they all are happy. He advised if close vision is most important go with Synergy and if less Dysphotopsias is most important go with PanOptics. I should that is if one wants a defractive IOL as he is still a fan of monofocals as he was when I had my first surgery.

He was actual a trial doctor for Symfony and was not thrilled with the Symfony saying his experience with that IOL was people got dysphotopsias and did not get good close vision.
