Scientific journals described the new innovation that scientists have recently come up with, as it may seem at first glance like a horror movie, but it is necessary and effective in many medical treatments related to eye diseases.
Scientists confirm that some eye diseases caused by needles not only look terrible, but there are diseases that may cause many risks, such as endophthalmitis, a bacterial infection that occurs due to bacteria that enter the eye through the holes made by ordinary needles (eye injection). .
In addition, repeated injections may cause severe damage to the eye tissue, and worse, cancer cells can float out of the newly made hole and spread to other areas of the human body.

In order to avoid these cases and reduce their incidence as much as possible, an international team of researchers has developed a new system that is likely to be the best to date, with the aim of delivering drugs into the eye without these complications.
According to the article published in the scientific journal “sciencealert”, the new technology has performed well in preclinical tests, but unfortunately for our “human nightmares”, the eye needle is still well deservedly at the top of its list, as the ordinary needle causes concern for many around the world, but that Eye intervention, this is a great challenge for the patient.
“This new improvement in drug delivery therapy can avert the problems associated with using needles to treat serious eye diseases,” said Ali Khadem Hosseini, one of the researchers on the project and director of the Terasaki Institute for Biomedical Innovation.

As the scientific term for an eye injection, scientists call it “intravitreous injection”, where the drug is placed in the vitreous (the gel-like fluid that fills the eyeball). It is used to treat a number of diseases, including age-related macular degeneration (AMD) and diabetic eye disease.

To avoid repeated injections, the team created an ultra-thin microneedle that stays true inside the eye and eventually dissolves.

The micro-needling contains a ‘stopper’ (hydrogel) to close the opening created with the goal of gradually releasing the encapsulated medication while it is inside the eye area.

Scientists have proven the effectiveness of this needle on a number of animals, including pigs, where the microscopic needle distributed the drug inside the eye with good efficiency and great effectiveness, which the researchers confirmed is an exciting discovery, which may provide a less terrible solution to the horror related to the eye needle.
