Cataracts are the clouding of the lens. The most common type of cataract is senile, associated with aging. Generally, cataracts are formed over the years as it loses crystal transparency and becomes opaque, so that the main cause of cataracts is age.
There are different types of less frequent falls, as congenital cataracts, traumatic cataracts or toxic cataracts, caused by certain drugs. There are also diseases such as diabetes, which can cause cataracts develop at an earlier age.
Symptoms of cataracts
Cataracts cause a progressive loss of vision, both far and near, and generate the feeling of having blurred vision and halos around lights that generate a growing discomfort when exposed to conditions of high luminosity.
Cataract diagnosis is made by the ophthalmologist by scanning with a slit lamp after dilating the pupils, visualizing the lens and assessing the degree of opacity present.
Treatment of cataracts
The only way to remove cataracts and restore vision is through surgery. This procedure can be performed using local anesthesia, anesthetic drops or a periocular injection into the eyelid.
After emptying the cloudy lens with an intraocular lens that can correct distance vision through a monofocal, or distance vision and near, intraocular lens by a multifocal intraocular lens is inserted. The high astigmatism can be corrected also using a toric intraocular lens.
Since it is an outpatient procedure, the procedure does not require hospitalization. Furthermore, the use of femtosecond lasers for cataract surgery makes the operation count with the following advantages: better centering of the intraocular lens, especially those demanding as the multifocal lens to eliminate the need for glasses both near and far, as well as minor ocular trauma, more accurate and safe and quick surgery.
