Choosing the right IOL when considering cataract surgery
April 6, 2023
What’s the difference between Diffractive and non-diffractive EDOF IOLs?
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, as you know, can malfunction. For the first time in history, a robot participated in an operation of this nature. The system is called PRECEYES, and it does not, of course, wear a white coat or work alone.
It’s an extension of the eyes and hands of the surgeon, but in some ways more intriguing. Any surgery requires precision, but microsurgery of the eye – absolute accuracy.
In this case, we are talking about the impact of macular degeneration, responsible for loss of central vision and the disappearance of small, subtle details.
A team of Oxford specialists under the direction of Robert McLaren led patients through the dissection of a specific membrane in the macula, a yellow spot. Its degeneration creates the aforementioned problems. Results from six patients, operated on by robots, were compared with six others operated on by humans.
The number of micro-traumas was estimated, which cannot be avoided in retinal operations, and it’s clear that less is better. In this area, there wasn’t much difference between the two groups. But in terms of speed, you might be surprised that man won. Humans took about 1.5 minutes, while robots took 5.
Let’s not forget that this was the first robot operation in the world and their times will steadily decrease. Accuracy and safety will grow. Robots have the potential for growth, and there are no human factors like stress, unintentional mistakes, or extraneous thoughts about the health care system.
This was all the first stage. In the second, robots injected patients with a drug to stop bleeding. Here, everything was successful.
“‘This is a huge leap forward for delicate and technically difficult surgery, which in time should significantly improve the quality and safety of this kind of operation,” says Robert McLaren.

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.
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!
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?
