➣ What is a cataract?
A cataract is the cloudiness of the natural lens of the eye, responsible for focusing light and producing sharp images. With age all natural lenses called crystalline lens becomes cloudy and hardens, resulting in a loss of visual function. The lens of the eye is clear at birth, but as we age it gradually looses its transparency. A cataract is painless and usually develops gradually over several months or years. Normally, the onset of a cataract in one or both eyes may cause decreased night vision, impaired depth perception, difficulty reading and reduced color discrimination.
➣ Who is affected?
Cataracts are the leading cause of vision loss among adults age 55 and older. In fact, poor vision from cataracts affects 60 percent of all adults over age 60. However, cataracts affect all ages as they also can result from traumas, heredity, and inborn errors of metabolism or medication usage.
➣ How are cataracts diagnosed?
There is no single, valid, objective test that indicates the presence of an operable cataract. At Airala Lazer and Cataract Institute, we analyze patient symptoms, perform a comprehensive eye exam and may test for glare disability and contrast sensitivity to make a diagnosis. The final decision to proceed with the surgery lies with the patient.
➣ How are cataracts treated?
Cataract may be treated with prescribed glasses, medication or surgery depending on the symptoms, complaints and age of the patient. Initially glasses are recommended. In cases in which glasses do not provide the visual acuity necessary to perform your daily activities with comfort, surgery may be indicated.
➣ What is cataract surgery?
Cataract Surgery involves the removal of your cloudy natural lens using a procedure called phacoemulsification. The procedure usually involves dissolving the natural cloudy lens using high frequency ultrasound through less than a 2.5-millimeter clear corneal incision. An artificial lens is then implanted. The surgery continues to improve with such recent developments as no-stitch surgery, topical anesthesia, surgical correction of astigmatism and new upgraded lens designs. In all successful surgeries, the patient is able to return to normal activity almost immediately after surgery and usually sees well within days.

As we age, the natural lens in our eye becomes less flexible. This lack of flexibility compromises the eye’s ability to switch from one focal point (objects at a distance – driving) to another focal point (objects that are close – reading). As a result, the eye remains focused at distance all the time and readers are required to do near work after age 40. This is called presbyopia.
Presbyopic Lensectomy is a great alternative for patients who are seeking LASIK surgery but are not good candidates because they are out of the treatment range. The surgery involves the removal of the eye’s natural lens that focuses the incoming and outgoing light rays. This natural lens is replaced with a new technology intra-ocular lens. This technology has been used around the world for many years with excellent results. It is a great treatment for patients who require not only distance glasses, but near glasses as well. The most common implants used are: Tecnis multifocal, Restor, Crystalens and Rezoom. We use all the implants depending on the patients needs and eye characteristics.
FDA studies on the Presbyopic implant have shown that over 93% of patients will not need to wear distance or computer glasses and that over 84% of patients will not need reading glasses, whereas 100% of these patients needed distance and reading glasses preoperatively; and, since the FDA studies, as we have gained more experience, the results are even better! We also use these high technology implants in upgraded cataract surgery.
