Cataract Surgery

What are cataracts?

 

Cataract is the loss of transparency of the crystalline lens.  

Together with the cornea, the crystalline lens (which is a transparent intraocular lens located behind the pupil) has the function of focusing light rays sharply on the retina. Due to various circumstances, the most common being advanced age, the crystalline lens may lose transparency and may become an opaque lens. The cataract will affect vision more and will be more advanced depending on its location in the crystalline lens and the loss of transparency it produces.  

According to the location of the cataracts, they can be:

  • Nuclear (in the nucleus of the crystalline lens)

  • Sub-capsular (under the capsule)

  • Cortical (located in the cortex).

 

Symptoms of cataracts

  • Loss of color intensity, predominantly yellowish tones.

  • Glare and reduced nighttime visibility.

  • Blurred and sometimes double vision.

Causes of cataracts

  • Aging process.

  • Congenital (inherited or born).

  • Diabetes.

  • Use of corticosteroid-type drugs.

  • Eye injuries (either from a blow, puncture, cut, burn or intense heat).

Como se realiza una cirugía de cataratas

Cataract treatment?


The most modern method for cataract removal is phacoemulsification.


Ultrasound is used to dissolve the crystalline lens, which is absorbed through a small cannula. Then, through a 2.8 mm incision, we introduce an intraocular lens through intraocular lens lens, which will compensate for the lens’ graduation as well as the possible myopia. myopia o hyperopia preoperative that the patient had.


The operation is performed on an outpatient basis does not require hospitalization, the duration of the surgery is approximately 20 minutes and is performed under local anesthesia. Once the procedure has been performed, the patient can go home on his or her own, with a very rapid visual recovery.
