Choosing the right IOL when considering cataract surgery
April 6, 2023
What’s the difference between Diffractive and non-diffractive EDOF IOLs?
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!
Blindness isn’t the most popular topic. Most likely, you’re already wanting to scroll past this page. As soon as you reach a certain age, though, the topic becomes quite fascinating.
Why? Because of things like age-related macular degeneration (AMD), which lead to blindness, especially in its “wet” form. It’s worse than a wet handshake.
AMD is a pathological growth of abnormal blood vessels in the retina. This affects the macula, causing it to pull away from its base. Consequently, you rapidly lose your central vision.
Not all is lost, though, because Lucentis treats AMD and has for a long time. The process slows down in 90% of cases.
Don’t forget that this requires an ophthalmology visit about once every two months. Injections go directly into the eye. Some forget, though, perhaps because of poor memory at that age.
This is why Genentech created a new delivery method, titled Port Delivery System.
This is the aforementioned grain of rice, as the device is about that size. Doctors implant it into the eye of the patient and it time-releases medication.
What happens when the medication runs out? It can be replenished.
It looks like a small dot on the surface of the eye, but is not visible because it hides underneath the eyelid.
So how well does it work? It keeps the “wet” form of AMD in check just as well as conventional injections. Furthermore, older patients may not have to see the doctor for at least 15 months! Then they get a top-off.
The method is also quite safe.
You may notice that we often describe products that aren’t yet on the market. So how long before this is available? About 3 years.
Project Manager Carl D Regillo believes that reducing the number of injections and doctor visits is a good in and of itself.
Their work wasn’t presented just anywhere, but at the 122nd annual meeting of the American Academy of Ophthalmology.

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.
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?
