Catarats


CATARACTS – PHACOEMULSIFICATION

The loss of transparency and mobility of the lens is called a cataract. The lens is a lens placed inside the eye, behind the pupil and their function is to focus clearly objects to change their shape and position.

Cataracts can occur at any age but are more frequent in people over 60 years due to the passage of time. There congenital cataracts in children born with cataracts caused by hereditary factors or diseases during pregnancy; others have cataracts at an early stage due to metabolic diseases. It can also be associated with severe myopia and ocular trauma.

With the passage of time or by disease (occasionally), the lens loses its transparency and natural elasticity and becomes opaque and rigid lens. Thus, the crystal loses its function. The waterfall can be mild or advanced as the loss of the lens is less than or greater. Consequently, the visual quality will suffer in proportion to the progress of the cataract.

 What is the treatment for cataracts?

Treatment of cataracts is surgical. The latest technique is called phacoemulsification and involves removal of the lens, which is opaque, ultrasound and is then replaced by an intraocular lens is placed in the same spot of the lens allowing the person, in most cases, regain lost vision.

It is usually an outpatient surgery is performed under local anesthesia (drops); ie, the patient returns home the same day. The intraocular lens or artificial implant is soft and pliable, which passes through a hole of about 3 mm.

 When should cataract surgery?

A time in which it was stated that there was a wait that “matured” to be operated cataract ago. Today, thanks to the modernization of the surgical techniques and advances in technology, the situation is exactly the reverse: the less “mature” is the cataract surgery is less complex.

This is a very low complication surgery and a short recovery period where the person can return to their activities in a short period of time.
