Inside the eyeball, there is a structure called crystalline lens, which is what allows us to see clearly at different distances when we are young. Precisely, thanks to the modification of its curvature and its diameter, it contributes to our being able to see clearly at near vision.
This accommodation mechanism, which acts in a similar way to the zoom function of a camera, facilitates the performance of everyday tasks such as reading on cell phones, tablets, computers or even paper texts, among others… However, with age the accommodation capacity of the crystalline lens deteriorates, leading to presbyopia, which hinders near vision.
When does presbyopia appear and why does it occur?
With age, near vision accommodation capacity deteriorates due to internal variations that occur in the ciliary body and the loss of elasticity of the crystalline lens itself. This loss of accommodation capacity begins to manifest itself at approximately 45 years of age, making it difficult to see objects in near vision in the process known as presbyopia or presbyopia.
Is there any way to prevent the manifestation of presbyopia?
Presbyopia is a condition that occurs in all people with age due to the aging of the crystalline lens and the decrease in the accommodation capacity of the ciliary muscle that contributes to the contraction and relation of the crystalline lens. These age-induced changes cannot be prevented because they are manifested by the aging of the structures of the eyeball itself, in a similar way as it could happen in other parts of the human body.
What are the symptoms and when should you see an ophthalmologist?
Presbyopia may not initially cause the patient to notice any symptoms in the quality of vision. However, as the accommodative ability of the crystalline lens continues to deteriorate, a decrease in the quality of vision at near distances during reading will begin to manifest itself.
One of the most characteristic symptoms at the onset of presbyopia is the need to move texts farther away in order to read them clearly. However, as presbyopia progresses and accommodative ability is reduced, the arm’s length will no longer be sufficient to read clearly. When the first symptoms of presbyopia begin to appear, it is advisable to visit a specialist in ophthalmology to analyze the optical quality of the eyeball and plan treatment.
Which ophthalmologic operation is the most advisable one?
There are different treatments for presbyopia, either ophthalmic lenses, treatments that act on the corneal surface or intraocular surgery. However, the implantation of Premium Intraocular Lenses is one of the most recommended options due to the innovations developed in its technology. The treatment of presbyopia using Premium Intraocular Lenses is one of the most frequently performed procedures at the Dr. Cristóbal Auladell Ophthalmology Center in Huelva due to its excellent results because it not only improves near vision. Likewise, its technology allows correcting the visual defect if the patient has myopia, hyperopia or astigmatism.
In addition, the design of the Premium Intraocular Lenses also allows for improved vision at night, added to the advantage that it is considered a minimal incision surgery in which no sutures are necessary. Among its many advantages, it is also noteworthy that in the future it will not be necessary to perform a second surgery to remove the opacified crystalline lens in the well-known cataract process, since the crystalline lens has been replaced by an intraocular lens for the treatment of presbyopia.
