Cataract surgery: visual quality

Cataracts are one of the leading causes of vision loss and are related to the progressive opacity of the crystalline lens, the natural lens in our eyes. As the cataract develops, vision is gradually affected, but cataract surgery offers an effective solution to restore visual clarity. We will explore what cataracts are, the benefits of surgery, the types of procedures and technologies used, as well as frequently asked questions and the different types of intraocular lenses available.

What is a cataract?

Cataracts are the consequence of lens aging or may be associated with congenital conditions, metabolic diseases, ocular trauma, among others.

  • Symptoms include:
  • Blurred or cloudy vision.
  • Change in color perception.
  • Glare and changes in night vision.
  • Vision of halos around lights.

What is cataract surgery and how can it change your life?

In our medical practice, we understand cataract surgery as a safe and effective procedure that involves removing the cloudy lens and replacing it with an intraocular lens. The benefits include rapid recovery, significant improvement in vision and the ability to reduce dependence on glasses, improving the visual quality of our patients.

Imagine living day after day without the need to reach for your glasses when you wake up. That freedom and comfort are possible thanks to the surgical techniques we apply.

Types of cataract surgery available in Colombia

There are several types of cataract surgery, each tailored to the individual needs of the patient. These include traditional surgery with phacoemulsification and femtosecond laser surgery.

Every day we witness how cataract surgery opens doors to a world that once seemed limited by visual barriers. We are honored to be part of this change that not only improves sight, but also enhances our patients’ enjoyment of life.

Types of intraocular lenses used for cataracts: An effective solution for restoring visual clarity

Intraocular lenses have evolved with technological advances. Among the options available are:

  • Monofocal lenses: Correct distance vision.
  • Multifocal lenses: Offer vision at various distances.
  • Toric lenses: Correct astigmatism.
  • Aspheric lenses: Improve visual quality.
  • Trifocal lenses: Offer vision at all distances including astigmatism.

With these advances, cataract surgery not only restores vision, but also provides customized options for each patient. If you are considering cataract surgery, don’t hesitate to consult our specialists for detailed, personalized information.

Everything you need to know about cataract surgery

How are cataracts classified?


  • According to their evolution: mature and immature depending on the degree of opacity.
  • According to the affected area of the lens: capsular, cortical or nuclear.
  • Congenital: present from birth due to developmental anomalies.
  • Senile: produced by age-related changes. They are the most common.
  • Traumatic: caused by blows, chemical burns or exposure to very high temperatures.
  • Secondary: caused by metabolic or nutritional disorders, inflammation, radiation exposure or prolonged use of steroids.

What are the symptoms of cataracts?

Initially there is:

Blurred or cloudy vision and decreased vision which progresses to total loss.

The evolution depends on the size and location.

Some cataracts produce greater visual distortion than others, such as nuclear and capsular cataracts.

Nuclear cataracts initially produce an effect that translates as an increase in refractive power and the patient notices that he/she can read without using the glasses that he/she usually requires.

Some patients report diplopia (double vision) or even present multiple images as a result of the irregular refraction, increased sensitivity to light and glare, making it difficult to drive at night.

Is there any treatment for cataracts?

When cataracts progress to cause significant vision loss, surgery should be considered, as it has been proven that other treatments cannot dissolve, reduce or eliminate cataracts.

Surgery is the only way to remove the cataractous lens and replace it with an intraocular lens.

How long does the procedure take?

Cataract surgery is usually performed in 40 minutes or less.

It is first performed on one eye and then surgery is scheduled on the other eye with close monitoring of the visual quality of our patients.

Does cataract surgery cause pain?

Cataract surgery operations are characterized mainly by being quick, painless, in most cases local anesthesia is used and do not require hospitalization.

What is the cataract surgery procedure like?

The cataract surgery procedure, known as phacoemulsification, is a highly specialized and precise process that is performed in stages.

Preoperative Examination: Prior to surgery, the ophthalmologist performs a detailed examination to assess eye health, determine the type of intraocular lens needed and measure the curvature of the cornea.

Anesthesia: A local anesthetic is administered around the eye to numb the area and ensure that the patient is comfortable during the procedure. In some cases, topical anesthetic in the form of drops may be used.

Small Incision: A small incision is made in the cornea to access the lens. The most common technique uses a phacoemulsification procedure with an incision of approximately 2-3 mm.

Phacoemulsification: An ultrasonic probe is used to fragment and emulsify the cataract, allowing its removal through the small incision. This process is called phacoemulsification.

Opaque Lens Aspiration: The emulsified lens is gently aspirated to make room for the intraocular lens.

Intraocular Lens Implantation (IOL): The selected intraocular lens is placed in the same place as the natural crystalline lens. These lenses can be monofocal, multifocal, toric or aspheric, depending on the patient’s needs.

Incision Closure: The small incision usually does not require stitches, as it tends to seal on its own. In some cases, a liquid sealant may be used.

How many days of disability does the surgery generate?

Cataract surgery is an outpatient procedure, and most people can return to their normal activities fairly quickly. In many cases, no prolonged period of disability is required. Most patients are able to return to work and normal daily activities within the first week and physical activities after the first month of surgery, depending on the speed of their recovery.

It is important to follow the specific recommendations of your ophthalmic surgeon and schedule follow-up examinations as needed. It should be noted that these time frames are general and may vary depending on individual circumstances and the technology used in the surgery.

How soon will I be able to see well?

The postoperative period following cataract eye surgery is fairly quick. If there are no setbacks, within a week you will have incredible vision again.

What care should I take after surgery?

After surgery, postoperative care instructions are provided. The patient may experience immediate improvement in vision, although it may take a few days or weeks for full vision to stabilize.

It is essential to follow the ophthalmologist’s instructions during the recovery period, which may include the use of medications and limitation of certain activities. Cataract surgery is a routine procedure with high success rates and low risks, and many people experience a significant improvement in their visual quality after the surgery.
