The Future of Eye Care: Exploring Online Cataract Tests

With aging, it is natural for vision problems to arise. Among them is the cataract which requires online cataract test. The good news is that cataract surgery returns the patient’s clear vision and can even help correct the degree in some situations.  If you have been diagnosed with cataracts and your doctor has indicated that you have surgery, there is no need to worry. This is a common problem; the procedure is quick, simple, and painless.


In this guide on Discover Vision, we explain more about the subject and even give you a super tip at the end: how to have cataract surgery without health insurance and at more affordable prices with the help of Vidia.  We are remembering that our goal is to inform you. In case of symptoms, look for an ophthalmologist, agreed?

What Is It?

Cataracts are one of the most common vision problems of aging.

Over time, this lens becomes opaque, which prevents the passage of light for the formation of images.  Because it is a progressive disease, if not treated, the cataract increasingly blurs the vision until the person can no longer see anything. The good news is that cataract surgery can completely reverse this process, as the lens is replaced with an artificial lens.

What are the warning signs?

Difficulty seeing that gets worse over time and does not resolve with the use of glasses is the main sign of cataracts. Do you have this symptom? Look for an ophthalmologist for the correct diagnosis and treatment.

When To Operate?

The only treatment for cataracts is surgery. Therefore, the patient must operate as soon as the disease is diagnosed. If the procedure is not performed, the disease progresses to total blindness.

What Exams Are Required?

Preoperative tests are ordered to assess the patient’s cataract and general ocular health. In addition to clinical exams, the following are usually on this list:

Corneal Specular Microscopy

Allows the study and counting of cells lining the deepest layer of the cornea.

Applanation Tonometry

They are used to diagnose ocular hypertension and assess for glaucoma.

Fundus Of The Eye Or Fundoscopy

Evaluates veins, arteries, and nerves of the eye to identify if some injuries or scars compromise vision.

Corneal Topography

It identifies corneal distortions and is used for cataract surgery planning.

Retinal Mapping

Scans the surface of the retina and surrounding structures to identify damage.

Macular Acuity Potential (MAP)

Evaluates the degree of sensitivity of patients with cataracts to luminous signs projected directly into the back of the eye. In this way, the surgeon can understand the patients’ vision potential when the opacity and irregularities caused by the disease are removed. Thus, predicting damage and establishing a visual acuity prognosis is possible after surgery.

Contrast Sensitivity Test

It tests the quality of vision in different light levels because cataracts decrease this sensitivity due to the opacity of the lens. The examination aims to determine the degree of impairment of this function. These are the most common preoperative exams for cataracts. But the list can vary according to the case, and the ophthalmologist can suggest others, if necessary.

Preoperative Care

Care before cataract surgery may vary from case to case. But some recommendations are common, such as using eye drops prescribed by the surgeon and suspending contact lenses in the determined period. In addition, on the day of the surgery, the patient must not wear makeup and must fast as recommended.
