What is Presbyopia definition/concept

It is a very common eye pathology and popularly known as eye strain. Presbyopia is the difficulty of looking closely and, as a general rule, it occurs after the age of 40 years.

In a normal situation, every individual has the ability to see from a distance and up close, without the slightest problem until the age of 40, but from this age onwards, problems related to the ability to focus the eyes begin to appear. This is because the lens no longer works with the same precision and the ability to focus on objects diminishes.

It can be said that lens zoom is damaged from 40 onwards as a natural process , so presbyopia is not an eye disease, but lens sclerosis (its wear) is what hinders the quality of vision.

It is not possible to prevent its appearance, but there is a corrective treatment

Although presbyopia cannot be prevented with any treatment or drug, ophthalmologists advise living a healthy life to delay its negative effects.

In relation to their treatment, the most common is to use corrective lenses. However, in recent years, laser eye surgery has allowed the lens to be corrected. Another technique used is the introduction of an intraocular lens that replaces crystalline wear and thus avoids the use of glasses.

To find out which technique is best, ophthalmologists perform a thorough examination of the patient to assess the condition of the cornea, lens and eye in general, then there is a series of additional tests, especially the ocular topography.

The information obtained and the patient’s personal circumstances allow a conclusion to be drawn as to which procedure would be the most appropriate to correct presbyopia. As the percentage of success of this type of corrective treatment increases, the more common is for the patient to regain normal vision.

With regard to the recovery phase after surgical correction of presbyopia, within a few days the patient will have normal vision again.

Common Eye Problems and Rare Diseases

In the field of ophthalmology, some diseases present themselves very frequently, such as astigmatism, myopia, farsightedness, conjunctivitis, cataracts and macular degeneration. On the other hand, there are diseases that are less common, such as glaucoma, trachoma, diabetic retinopathy and amaurosis.
