Choosing the right IOL when considering cataract surgery

What’s the difference between Diffractive and non-diffractive EDOF IOLs?
Researchers observed a sizable population for 15 years, which demonstrated that the probability of developing macular degeneration was 60% lower in orange lovers than in orange haters. Flavonoids, according to the study's author, are most likely what cause this impact. Numerous authors adore the word "flavonoids" because it is so lovely. However, what are they?
What’s the deal with oranges and blindness? And what does this have to do with gibberish? New research shows that people with a weakness for oranges are less likely to develop macular degeneration than those who hate them.
Macular degeneration is a common cause of blindness among relatively elderly folks.
For 15 years, researchers monitored a large group of people. They showed that orange-lovers were at 60% less of a risk than orange-o-phobes.
If you eat oranges once a day, then you fall in that first group. Even if you only eat them once a week, though, you’ll still see benefits.
The study’s author says that flavonoids are most likely responsible for this effect.
Perhaps you’re tired of reading the superficial, pop-science notes about the latest discoveries. But do we have a chance to get further into the subject? I’m afraid not.
For example, “flavonoids” is a beautiful word admired by countless authors. But what are they?
“Flavonoids are the largest class of vegetable polyphenols” (wiki). It doesn’t help to read more, because we then learn that they’re “hydroxy derivatives of flavones”. What’s a flavone? We’re not going to advance more than two turns here.
Or maybe we can learn a little about phenols. After all, you’ve encountered this magical formula – “The polyphenols in green tea are a powerful antioxidant”. Obviously, though, in order to understand polyphenols, we have to start with phenols. Let’s look at the literature:
“Phenols are organic compounds composed of aromatic rings,” but then what? A knowledge of chemical sciences is needed. Or perhaps you know what an “aromatic carbon ring” means? For the rest of us, it’s gibberish. It sounds scientific, at least, but it makes no sense to the common man.
Therefore, the average reader here decides rather quickly that it’s incomprehensible. They take the scientists’ word for it, and this is where science intersects with faith.

We’re content with simply knowing that many flavonoids are the pigments that color plants red, purple, yellow, or whatever. And that some of these pigments have a positive effect on health.
It’s also that “flavonoids are the strongest antioxidants”. We won’t worry about this anymore, though. The word has been beat to death, but a quick survey of the population will show you that few people know what it is.
Ultimately, the main thing worth remembering is that oranges are good for the eyes.
“Why didn’t you just come out and say that immediately, then?” “You wouldn’t have believed it”.
S.V.
What’s the difference between Diffractive and non-diffractive EDOF IOLs?
We will open up about whether there is at least something beautiful behind these magic words – macular degeneration and diabetic retinopathy. What kind of unpleasant disease lies under such an interesting "keratoconus" and what is the connection with the cone?
Despite the fact that Macular Degeneration considered as a disease of kings, now it affects and leads to blindness not only to a privileged society. The light of hope was received from a group of American ophthalmologists who saved four patients from blindness with a new method that’s described in the Journal of Translational
Medicine.
For the first time in history, a robot called PRECEYES participated in an operation. The task was to dissect a specific membrane in the macula, a yellow spot of patients with macular degeneration. Results from six patients, operated on by robots, were compared with six others operated on by humans, but in terms of speed, you might be surprised that man won. Humans 1.5 minutes against robots 5.
The retina is a portal to your brain. According to new data, Alzheimer’s can show itself through some eye diseases that affect the retina. If problems begin in retina, it could be a symptom of physiological abnormalities in the brain. Also, retinal problems can indicate such diseases as diabetes, atherosclerosis. etc.
Future is officially here! Optos is the modern diagnostic equipment for systemic and ocular retinal diseases. With the assistance of Optos, ophthalmologist can take a fundus photo and see the rear of the eye for potential retinal tears.
Genentech has created a new delivery method for medications needed to prevent age related macular degeneration (AMD) called Port Delivery System. It resembles a small grain of rice that goes directly into your eye and time-releases medication. Genius!
Finally, there’s a light at the end of the tunnel in the treatment of macular degeneration (MD). Scientists have discovered that the main culprit is an enzyme and trying to determine the level of them in the patient's eyes. This enzyme plays an important role in the destruction of retinal cells and ultimately blindness. But does it mean it's time to throw our hats in the air?
