Introduction: Cataracts, a protein buildup that clouds the lens of the eye, is the leading cause of blindness around the world. In most cases the patient will eventually need surgery to replace the clouded lens with an artificial one, and sometimes it doesn’t always fully repair their vision. Today researchers have designed a surgical technique that uses the body’s own stem cells to regenerate a functional lens, a less invasive method than the prevalent remedy. This is not a typical contact lens, because the lens is made up of cells removed from common cornea bonds. These special mesenchymal stem cells encourage the injured eye to repair their wounds. The lens can be damaged in a few hours in the eye and it seems easier and cheaper to use it than current treatments. Also, this treatment method it can be promising for patients with chronic diseases such as corneal ulcers and frequent eye defects that do not respond to common treatments.
Methods: The researchers, using sophisticated techniques, were able to produce a biodegradable sheet that could be placed on the cornea. This page is full of stem cells that can reproduce and allow the body to naturally repair the eye. One of the features of this new page is that it contains small packages containing stem cells that hold them together and put them together. Another benefit of this page is that it is degradable and its material is similar to the material used in the eye structures, so there will be no problem with the immune system.
Results: The researchers developed a method that helped them to keep the functional stem cells in the lens while removing the non-functional lens. When they tested this on rabbits, the results showed that the animals’ eyes had regenerated functional lenses without cataracts in a short time. Based on the new proposed approach, the cells needed to prepare the lens are provided with a donor cell and then used to make the lens. This form of treatment can be more effective than current therapies due to the use of amniotic membrane that is provided from human placenta and due to its rapid application and its different therapeutic properties.
Conclusion: Scientists hope that derived stem cells can reduce inflammation of the corneal abnormalities and provide the possibility of a natural regeneration of the wounds. Patients after transplantation of stem cells can, depending on the severity of their visual impairment, get.

The new Method should be faster and cheaper. Approval and ensuring the effectiveness of these types of lenses requires several years of extensive testing and clinical examinations to be made available to the general public. However, the initial results of these experiments are promising. these lenses have not yet been completed and should not forget the importance of using them.
