The fight against aging is one of the characteristics of our society and in this line would be presbyopia or eyestrain. The fact of having to use glasses closely denotes a certain age, in addition to the inconvenience that supposes for the practice of the sport or other activities, something that can become a real problem for a wide group of people.
The causes of presbyopia have many nuances but in a general way we can say that it is due to the aging process of the structures related to the mechanisms of focus , the accommodation. With age, the elasticity of the natural lens of the eye, the crystalline lens, is lost, its volume increases and the macula-tendinous structure that regulates its shape and power loses efficiency, that is, presbyopia is a multifactorial process.
At present we can not say that there is a single treatment fully effective and with maximum safety (the origin is multifactorial), but those of us dedicated to treating presbyopia, we can say that in most cases there is a treatment that can be very effective and safe for each person even for those who are previously operated on for myopia, hyperopia or astigmatism .
The therapeutic possibilities are very varied as well as the requirements of the patients, the ophthalmologist must analyze the needs of each individual, the state of their eyes and even their general state and with it decide which is the best option or the combination of several of them .
A presbyopic specialist must be an expert in very different areas of ophthalmology , from pharmacology to handle eye drops that can help your treatment, multifocal contact lenses and visual therapies with exercises, to surgical techniques such as laser and intraocular lenses and more recently the implants in cornea and sclera , which requires a very experienced ophthalmologist and who has the necessary instruments to be able to carry out the adequate analysis for each individual and finally to be able to establish an accurate treatment.
These factors explain why there are still no specific centers to treat presbyopia , not so much because there are no treatments, but because there are few ophthalmologists who master all the techniques and because the cost of machinery and personnel for diagnosis and treatment are high .
