Choosing the right IOL when considering cataract surgery
April 6, 2023
What’s the difference between Diffractive and non-diffractive EDOF IOLs?
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?
THE VICTORY OVER MACULAR DEGENERATION – COMING SOON!
“If macular degeneration (MD) were a country, it would be the eighth most populous country in the world,” said one scientist.
Yes – 200 million people would live there. Remember, this is the primary reason for loss of vision. Finally, there’s a light at the end of the tunnel!
They’ve discovered a trigger that leads to this inflammation. It turns out that the main culprit is an enzyme. This enzyme plays an important role in the organism’s immune response to infection, as it detects foreign DNA, but it also has a negative role in the dry form of MD, usually associated with age.
In a sense, this is surprising, because MD has nothing to do with viruses or bacteria. Nevertheless, the enzyme sounds the alarm, leading to the destruction of retinal cells and ultimately blindness.
This enzyme reacts not only to pathogens, but also to other dangerous problems that require an immune response, and it’s possible that it plays a similar role with diabetes, lupus, and obesity. Physicians are already working on drugs that block this mechanism which pits the immune system against its own organism.
But let’s not throw our hats in the air just yet – it will be another couple of years before this treatment is ready, and then there will be checks for effectiveness and safety…
In the meantime, scientists are trying to determine the level of the enzyme in the patients’ eyes. This will give them the opportunity to decide when to start blocking it, and it will have a level of accuracy down to a single molecule.
Here at BEI, as you know, accuracy is highly prized, so we will be following these events closely.

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.
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?
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!
