Choosing the right IOL when considering cataract surgery

What’s the difference between Diffractive and non-diffractive EDOF IOLs?
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.
The retina is kind of a portal to your brain. According to new data, Alzheimer’s can show itself through some eye diseases that affect the retina.
There are so many people on Earth with dementia that they could start their own country. 46 million. In another 30 years, the population of that country will swell to 130 million.
It very much appears to be that glaucoma, macular degeneration, and diabetic retinopathy are related to the development of this problem.
Scientists monitored a number of elderly patients who did not have Alzheimer’s at the time of their first examination.
By the end of the study, however, 1 out of 5 developed dementia. It seems that those who have had these three eye diseases are at a 40-50% higher risk than others.
Primary care doctors should send such patients to be checked for dementia.
Another group of scientists confirmed this observation. A recent article in the Neurology journal cited a connection between retinal problems and a reduction in mental faculty.
Fortunately, there does not seem to be a relationship between cataracts and dementia: it is just an age-related opacification of the lens.
But with other eye diseases, which we have written about many times, they are not solely associated with dementia.
The retina is the window to the brain. If problems begin there, they are a symptom of physiological abnormalities in the brain.
For example, the optic nerve ends in the retina, and if there is swelling in that area there might be a tumor in the brain.
The mechanism is simple. The tumor presses on the brain, creating intracranial pressure, which leads to swelling of the optic nerve. You can see this on the retina, especially if you have the best diagnostic equipment in the world, like at BEI. Not everywhere has such amazing equipment, though.
Diabetes. If you have partial vision and the rest is blurred, it is likely you have diabetic retinopathy.
Or another variant – hypertensive retinopathy.
What else? Atherosclerosis also depletes the optic nerve, leading to a loss of vision. This is also seen in the retina.
If the patient has Graves disease, the ophthalmologist can tell just by looking at their face. This is an autoimmune disease that causes swelling and inflammation of the eyes.
As you can see, the retina is a more reliable method of diagnosis than palm-reading, or even reading internet forums.

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.
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!
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?
