¿What is cataract

?

A cataract is a physiological change that sooner or later affects everyone and is the clouding of the lens, we have a natural lens inside the eye. Let's understand a little better: a model eye ( an eye where there has been a cross- cutting ) we see the retina and nerve in the back of the eye. In the front is situated the cornea, which is transparent, behind the iris is found, ie the part that provides the color of the eye, and behind this, surrounded by the ciliary muscle, the lens. Crystal under the effect of the eye muscle, the next focus objects. Initially the lens is transparent and flexible, but over the years lost its flexibility and that's when we started to need glasses to see the next objects. This refractive error is known as presbyopia. Unfortunately the process of degeneration of the lens goes beyond its flexibility and lens, initially transparent, this feature is lost gradually becoming opaque crystal. That is when we talk about Falls. What happens is that the light entering the eye is scattered by the clouding of the lens and the patient noticed difficulty in vision, especially in situations of changes in light or driving, even though there are remedies before the phenomenon reaches these extremes

¿How can we solve the problem of cataract

?

There is no treatment with drops or laser that you can solve the falls: the only solution is surgical. The surgery is to restore the cloudy lens for clear lens. This is done by introducing two small ultrasound needles that allow us to undo the lens inside the eye and replace it with another transparent. We restored so that light passing back through the eye pupil. The procedure is performed through a very small incision of less than 2 mm sutureless, without anesthesia and without punctures; This allows the patient to quickly reintegrate into their daily lives. No need for a post -operative itself.

¿What are the risks of surgery and how old is recommended for application

?

There may be a fairly significant risk of infection. Unfortunately all surgical interventions have it. No clutch in ophthalmology for this risk is very low, in fact it is less than one in five thousand surgery. But it is still a risk, so before, during and up to two weeks after the intervention the patient will be subjected to a treatment with antibiotics. For any questions or any situation should consult with your ophthalmologist. The recommended age to have cataract surgery is when the patient actually manifest symptoms;is not necessary, contrary to what is popularly believed, expect cataracts are ripe. In contrast to current techniques is recommended undo inside the eye when not too made ​​-that limits the energy we use and therefore it facilitates the immediate postoperative period

¿They will have to wear glasses after intervention

?

The patient does not need glasses for distance vision. Depending on the type of lens we implant may have to need glasses for close vision. Since some years we have new lenses, called multifocal lenses that create two images inside the eye: an image from far and near another. The brain must be able, depending on the circumstances, to choose which of the two images is appropriate at all times for a vision nitida. Unfortunately not all patients are willing or get used to the difficulties of adaptation that requires the implantation of these lenses. Also, not all patients are candidates for implantation of these multifocal lenses. The valuation is very important for your eye doctor and the patient understands the limitations and expectations of this type of treatment.
