Cataract

Cataracts affect over 50% of people over the age of 65.

The most common vision loss occurs due to the opacity of the crystalline lens, known as cataracts. This problem is solved with surgery, which we perform on an outpatient basis (without hospitalisation) and under local anaesthesia (with anaesthetic drops). Furthermore, this surgery does not require to cover the operated eye. This surgery consists in making small incisions in the cornea that allow us to remove the opaque crystalline lens and replace it with an intraocular lens. After the cataract surgery, the intraocular lens will carry out the functions that previously corresponded to the crystalline lens. This is why making a good lens choice is essential.

At Clínica Oftalmológica Castro the choice of the best lens type is made after a careful assessment of the patient's needs.

Types of lens

Standard Lens:

Monofocal lens (single focus): For long-distance vision. Compensates for spherical dioptres, requiring glasses for near vision.

Premium Lenses:

The aim is to improve the quality of intermediate and near vision, reducing or even avoiding the use of glasses.

  • Comfort: For long-distance and intermediate vision. Compensates for spherical dioptres, requiring glasses for near vision.
  • Trifocal (more than one focus): For long-distance, intermediate and near vision. Sometimes trifocal lenses can produce more halos (glare, brightness, etc.), so they are not recommended for night drivers. As with all trifocal lens implants, a neurosensory settling period is necessary. In rare cases when the patient is unable to adapt, the explantation of the lens may be necessary.
  • Premium toric: Compensates for astigmatism and sphere. Recommended from 1.5 dioptres of corneal astigmatism, to compensate for this astigmatism.
