Cataracts

Say goodbye to blurred vision

Don’t let the waterfall dim the brightest moments of your life.

Symptoms

Cataracts can develop in one or both eyes. They always develop slowly and progressively, so depending on the size and areas of clouding in the lens, a person may not realize they are developing a cataract. These are the main symptoms:

· Glare, especially at night, making driving difficult.
· Alteration in the perception of colors.
· Diplopia or double vision.
· Blurred or opaque vision.
· Frequent changes in your glasses or contact lens prescription.

Cataract surgery is the safest and most common ophthalmic procedure in the world.

Causes of presbyopia

Cataracts appear due to the aging of the lens. However, there are some risk factors that can lead to the development of cataracts and, consequently, vision loss:

· Suffer from diabetes.
· Eye trauma.
· Inflammation of the eyes (uveitis).
· Family history.
·Long-term use of corticosteroids or other medications.

High-definition vision: from screen to real life, without limitations.

How can it be diagnosed?

There are various tests for the diagnosis of cataracts, such as the determination of visual acuity. 

During an examination, the doctor can detect a cataract while examining the eye with a slit lamp that allows the cataract and its degree of opacity to be seen.

Thanks to the biometer, the diopters of the lens to be implanted can be calculated.

What treatments are available?

The only truly effective treatment is surgery. This technique basically involves removing the cloudy lens. During the procedure, a small incision of less than 3 millimeters is made in the cornea. The cataract is then removed using ultrasound, and an intraocular lens is inserted through the same incision to replace the cloudy lens.

Waterfalls out, clear vision in: innovation that changes your everyday life.

When is the best time for surgery?

At PRESBIT, we work with our patients to decide the best time to undergo surgery, which is typically when vision loss affects their quality of life.

Currently, cataract surgery is performed as soon as possible, when the patient begins to notice symptoms and perceive a deterioration in the quality of his or her vision (regardless of whether or not he or she has other refractive problems such as myopia, hyperopia, astigmatism or presbyopia).
