Common Questions About Cataract

Most patients who need cataract surgery often ask many questions about the intervention. The operation is being done to remove the cloudy lens (cataract) is called phacoemulsification.

To try to answer your questions about this type of surgery, we conducted this survey with answers compiled from the questions that other patients have done as you wanted surgery.

What are Cataracts?

Cataracts are the progressive development of a clouding of the lens (lens) of the eye that interferes with the passage of light to the retina, causing decreased vision.

Persons affected by cataracts complain of poor vision and / or glare, and undergo frequent changes in glasses graduation.

At first, when the cataract is very dense, it shows a blurring of the vision. Also, the lights (such as from the sun, lamps, car headlights, etc.) can cause more glare than usual.

As the cataract develops, vision becomes blurred, preventing progressively performing daily activities

What is the solution for Cataract?

The only solution is surgery.

When should operate and why?

A few years ago the indication for operation was when the vision was weak. Today to be able to benefit from the latest techniques, you do not get completely lost vision, but it is more beneficial when cataract surgery is not very advanced, which will allow us to remove it using ultrasound.

This is an innovative technique that involves inserting a probe of about 3.2 mm. inside the eye. This probe emits ultrasound responsible for "spraying" CATARACT.

With this technique you will get:

  • An eye opening lower, with the possibility of implanting a lens to be less pliable and incision, the procedure is safer and faster functional recovery.
  • This technique allows us to intervene with topical anesthesia (drops only) without pricking in the eye, it is virtually painless and the patient leaves the operating room with the eyes uncovered and having quickly recovered normal vision.
  • In this way the patient does not have to enter the clinic, the procedure is faster and functional recovery and this has a positive impact on patient satisfaction.
  • By implanting an intraocular lens, rather than the cloudy lens, we can select the dioptric power of the lens that will be putting together a post with what the patient will not have to wear glasses, and if it does it will be a small graduation.

How cataract blindness occur?

The lens is placed inside the eye that normally should be transparent. Its function is to change the focus of the eye for near and far objects. When the lens loses its transparency prevents light from objects properly focus on the retina. When this occurs decreases the quality and quantity of vision to the point of producing blindness.

What are the different types of cataracts?

There are different types of cataracts, but among the most common are the so-called senile cataracts. They occur in people over 50 years. The lens becomes cloudy due to damage suffered its fibers over time. This is because the lens fibers are not replaced during the life of an individual but new fibers are added to the outermost layer of the lens. In this way the center of the lens fibers are older than the same person as they are in that position before birth.

Oxidant molecules could be damaging the lens fibers. It has also been associated with cataract formation increased exposure to ultraviolet radiation (the type of sunlight).

What are the symptoms that cause cataracts?

The main symptom is decreased vision. They are also associated with loss of color saturation (the colors look less 'alive') and poor vision at night. Cataracts do not cause burning, tearing, or headache.

What is the treatment for cataracts?

So far has not discovered a drug that will restore transparency to the lens. The glasses also improve vision as to be opaque lens, does not allow the passage of light and would be like trying to wear glasses to see through a wall. The only solution now is to remove the cloudy lens (cataract) by surgery. There are different types of cataract surgery being the most safe and effective technique called phacoemulsification.

How to detect cataracts?

When you notice any of the symptoms described above should go to the ophthalmologist. Performing a full scan, the ophthalmologist will know whether or not if you have cataracts.

What is phacoemulsification?

Using ultrasonic energy, the cloudy lens (cataract) is sprayed into microparticles which are sucked inside the eye. This is accomplished with a fine terminal, which is inserted into the anterior chamber through a minimum opening (which varies between 2 to 3 millimeters). In this way the recovery of the patient is much quicker. This is known as minimally invasive surgery.

When should I have surgery?

Intervention is generally recommended when the patient begins to find difficulty in performing everyday tasks.

Will I feel pain during or after the operation?

Phacoemulsification technique is not painful during or after surgery. In fact performed under topical anesthesia (drops) without injections. Most patients report a sensation of pressure only due to the devices that immobilize the eye when performing surgery, and slight sting in the hours following it.

When I can start a normal life after surgery?

After surgery, the patient should be at home resting about 24 hours. The next morning, the visual improvement is so important that most patients can start doing your normal life.

What kind of precautions should I take after surgery?

The patient will use eye drops (antibiotic and anti-inflammatory) for 15 days. It is totally counter rubbing your eyes for at least a month after surgery, and should be avoided over six months. Sports activities can be practiced whenever used protective goggles. Makeup will be avoided during the month after the intervention.

Are there any risks using this technique?

As with any surgical procedure there are always risks, but these are minimal. Phacoemulsification is one of the safest surgical techniques and accurate that exist today, and provides the patient the option to return to normal duties almost immediately after the intervention.

Can operate both eyes at the same time?

Usually both eyes are not in the same surgical session, unless the patient's own medical reasons so recommended. Although the possibility of complications is minimal, being not recommend intraocular surgery involved both eyes at once.

Do I need to wear glasses after surgery?

The improvement in quality of life of cataract patients today is extraordinary. Most patients can perform normal activities far vision without using glasses. You will need to use reading glasses unless you have decided, on the advice of the surgeon, to opt for monovision or multifocal intraocular lenses.

What is monovision?

If you wish not to rely on glasses after cataract surgery, it is possible with monovision, it can get focus an eye for and one for close distance, placing in each eye the IOL appropriately. Ask about it before surgery.

What are multifocal lenses?

Another possibility to not depend on glasses after cataract surgery is to implant multifocal or progressive lenses, which allow as multifocal glasses focus at different distances. This type of lens is not indicated in all patients, but maybe you if you can benefit from them.

I have another question that has not been clarified in this questionnaire. How I can solve it?

I am interested in surgery? What should I do now?
