Cataract is quite common in old age. A cataract is a kind of clouding that envelops the crystalline lens of the eye. Varying in degree from slight to complete opacity, cataract happens to obstruct the passage of light, Although it is much common in old age, it can sometimes be caused due to eye injury, exposure to radiation or may be a birth defect in children. This is generally caused due to gradual discoloration or protein clumping. Both eyes can be affected due to this condition, but there are cases of one eye being affected by a cataract. Some factors that are responsible for the development of cataracts at an early age include excessive medications, such as oral, topical or inhaled steroids.
The common symptoms of cataract are blurred vision, difficulty with glare, dull color vision increases nearsightedness accompanied by frequent changes in eyeglass prescription, and occasionally double vision in eye. If not treated on time, cataracts may lead to serious conditions such as vision loss and blindness too.
Therefore, it is important to visit doctor at the earliest before it is too late. Surgery is often suggested to successfully remove cataract. The standard cataract surgery in Miami and Boca Raton FL is performed in eye clinic which is well-equipped with latest advances of technology. Here, the cloudy lens will be removed with an artificial lens. There are mainly three procedures of doing cataract surgery namely Extracapsular cataract surgery, Phacoemulsofication (Phaco), and Intracapsular cataract surgery.
Phacoemulsification process requires a small incision in the surface of the eye or near the cornea. A thin ultrasound probe is inserted into the eye to break the cataracts into fragmented pieces which are the carefully suctioned through the same probe.
Extrcapsular cataract surgery is usually recommended for those having advanced cataracts where the lens is too dense to dissolve into fragments. The surgeon makes a longer incision on the side of the cornea and the lens removed in one piece. Visual recovery is quite slower and discomfort is usually high compared to phaco.
Intracapsular cataract surgery is even larger than Extracapsular surgery. It requires the removal of the entire lens and the surrounding capsule all together. The surgeon removes the cataractous lens and puts a plastic lens which stays in the eye permanently.
Of all IOL implants, the most popular is the monofocal lens. This lens is particularly prescribed to the patients having difficulty with distant vision. However, it is very poor in near vision especially when reading. For this, corrective glasses or contact lenses are required for near vision. Monofocal lens cannot correct astigmatism.
In contrast, multifocal lens in Miami and Palm Beach FL has different regions of magnification that allow the patient to see in different distances. Unlike monofocal lens, it is good in near vision, allowing the patient to read and write, but the multifocal lens does not correct astigmatism. For this reason, some patients need corrective glasses or contacts.
With advancements in laser and probe surgery, cataract patients can usually seek treatment for other eye problems after the cataract has been removed.
After the surgery is over, patients are prescribed eye-drops and wear protective eye wear to keep their eyes safe from dust, allergy or glare.
