Tetraflex accommodating intraocular lens

The other thing the Symfony does is to correct for "chromatic aberration", an issue which is discussed in this industry publication which quotes one prominent surgeon noting: Cataract surgery with an IOL with an Abbe number greater than that of the natural lens (47) can improve CA, so that our cataract patients could actually experience better vision quality than they did as young adults." Although the Symfony uses a high Abbe material (I'm assuming its the same Tecnis material that article lists as having a 55 Abbe), it also has other features to to correct for CA to improve image quality.

There is also concern I'd read among some over whether over decades of aging anything would interfere with the physical movement of the lens, something non-accommodating lenses don't require.I'm assuming the RX for your right eye of -8.25 is for glasses.Contact lens powers are a bit different since the lens is at a different distance from your eye, so a conversion chart shows a -8.25D glass prescription is about a -7.75D contact lens prescription.I had originally only planned on having 1 eye done (since the other was 20/20 correctible still), but when the patch came off the next day I discovered it might be hard to adapt to the difference in vision between the two eyes even with a contact lens in the other eye.I might have quickly adapted if I'd taken the time, but I decided I didn't want to risk it, so I had the 2nd eye operated on a few hours later.
