Operational intervention is one of the most common methods of restoring sight to people. It is hard to imagine that about 650,000 operations are performed in front of the eyes every year. In Russia alone, I perform eye surgery on more than 30 thousand patients a year.
Nowadays, eye surgeries are not difficult. But in the postoperative period, some complications are also possible. After all, the operated eye must be treated with special medications.
It's hard to calculate the dosage
The difficulty is that it is very difficult to calculate the dosage of the drug needed in the postoperative period. And the most important thing is that it is necessary to apply the drug exactly in a certain place, affecting the eye tissues nearby. Therefore, doctors acted, as it is called, with a margin. And this can lead to an overdose of the drug and even to an increase in recovery time.
Microcrystalline cellulose as a drug guide
Microcrystalline cellulose was proposed as a carrier of the drug. Thanks to its use, the drugs get exactly where they are needed and in exactly the amount that is needed.
Who suggested this method
Proposed this method in Samara - at the Samara National Research University. The method was developed jointly with the staff of the Scientific Research Institute of Eye Diseases at the Samara Regional Ophthalmological Hospital.
Significantly cheaper than imported drugs
The most important thing is that the drug developed in Samara is as good as its imported analogs. Or rather, it is inferior. But only in price. For it costs six to seven times cheaper than imported drugs aimed at the same thing. The packaging of imported drugs costs more than 350 dollars.
Um, it is not difficult to calculate that patients' recovery period after surgery in front of their eyes will cost much cheaper. Despite all our insurance medicine, I very much doubt that the Samara patients did not have to pay for the medicines necessary for a speedy recovery after surgery.
I hope that after the clinical trials, the surgery to restore vision will be cheaper.
In the eye - through micro-cutting and without ultrasound
While Samara is deciding how to shorten the recovery period after eye surgery, Nizhny Novgorod is trying to reduce the time of the operation itself and minimize any complications that may arise. After all, cataract is now removed through micro-cutting. And even without ultrasound.
How to remove cataract earlier
Lens blur was previously considered a disease of the elderly, as well as people with diabetes mellitus, and some others. Today, cataract is young and can appear even in young people without any reason. Or rather, the preconditions in the form of certain diseases.
In order to remove dense cataracts, older people used to have a three-millimeter incision. Now - from 2.2 to 2.5 mm. Used and ultrasound, because the lens becomes hard and destroys it without laser energy is impossible. That is, the crystalline lens was crushed through the incisions, removing its fragments, and then the artificial lens was implanted.
One wrong movement of the doctor - and there were quite a few unpleasant consequences. The patient's recovery took a week to complete.
What is the method of
Medics have not only reduced the size of the incision required to remove the cataract. It was reduced to 1 and 1.5 mm. Scientists have eliminated the need to use ultrasound. They also invented and made a model of the lens. Introduced new surgical instruments, which are themselves developed. Vacuum is used to remove lens fragments. The operation takes five to ten minutes. The recovery period does not take more than a day. After all, with a smaller incision and a shorter recovery period.
Whose development
We proposed a new method, as already mentioned, in Nizhny Novgorod. Namely in Nizhny Novgorod State Academy. Therewith already the second decade spend operations with micro cut, for what artificial lens, special toolkit for work with micro cut are created and patented.
To introduce the method everywhere, alas, for today speech does not go. In Russia for such operations simply there is no necessary tool. So far only Nizhny Novgorod citizens are lucky. And they have also developed revolutionary methods of glaucoma treatment there.
