The ReLEx SMILE technique is the most modern treatment for myopia and astigmatism. At Laservisión we are leading experts in the use of this technique.
It becomes an additional lens in the ocular system. The ICL
is designed in such a way that it can correct myopia and hypermetropia. The toric ICL
can also correct a stigmatism when it presents associated with myopia.
The lens works by changing the focus point of light on the retina.
A cataract is total or partial opacification of the crystalline lens (the eye’s natural lens) that progressively reduces vision. A cataract is normally associated with age, although it can be congenital or occur through trauma.
There are different techniques for seeing close-up without glasses, all have advantages and disadvantages
The retina and thus the macula also rest on another layer of the back of the eye called the choroid. This provides oxygen and nutrients to the retina and is responsible for cleaning the waste products generated by the retina.
All these exchanges must be made through a very thin membrane that exists between the retina and the choroid, the Bruch membrane. Well, it is precisely the anomalies in this latter structure that initially cause AMD.
Thus, these changes may impede the proper nutrition of the retina resulting in the secondary degeneration of the retina that is supported on that area, which is known by dry or atrophic form of the disease.
The other possibility is that as a stimulus to the lack of nutrients and oxygen, the growth of abnormal vessels will develop and eventually destroy the surrounding structures as they grow, which is known as a wet or exudative form.
Pterygium is the abnormal growth of tissue on the conjunctiva, which tends to go from the tear ducts towards the cornea.
The endothelium is a layer of uniformly sized cells with hexagonal shape, which acts as a semipermeable membrane that allows the flow of aqueous humour that supplies the cornea with glucose and other nutrients. Its main function is removing water from the cornea to maintain its transparency.
