Blurry vision that comes with advancing age has become a problem in elderly people until it is common for them to carry eye-glasses at all times. The most common eyes disorders are aged-related farsightedness and cataracts. These disorders result in blurry vision, not being able to read well or driving at night. In average, the lens of the normal eyes in people aged 40-year-old up become less flexible and the ability to focus the image decreases causing a defect in vision. Common symptoms aredeclining visual abilities such as eye fatigue when reading, trouble focusing on nearby objects, aged related changes. When the eyes’ lens become thicker and harder at the center, it has a direct impact on the focus ability which require reading glasses when reading newspaper or doing embroidery. While “cataract” are part of the normal aging process when the lens in your eye begin cloudy, you may begin to find that it interferes with your daily activities such as driving and reading. If no proper treatment is done, it may eventually lead to acute glaucoma and blindness.
Cataract symptom progression Gradually, as cataracts progress, you may have symptoms such as: sensitivity to light and glare; painless cloudy, blurry or dim vision. Sometimes cataract is caused by the effects of certain drugs such as steroids; other eye diseases like uvitis and genetic disorders as well as infections during pregnancy when mother got rubella during the first 3 trimester. Nowadays, people with cataract with or without natural farsightedness condition will be treated with surgery in order to remove eye's cloudy natural lens and replaced with a clear artificial lens implant. This method will help improve your vision without wearing eye-glasses.
Treating cataract can be done by surgery to remove the hazy lens and to replace it with a tiny artificial lens that is permanently implanted in the eye. Currently there are two surgery methods. Extracapsular cataract extraction (ECCE) in which the surgeon makes a tiny incision about 10 millimeters in the white of the eye near the outer edge of the cornea to remove natural lens. After that a prescription intraocular lens implant is placed behind the iris where the eye's natural lens used to be and the incision is closed. The other method is called Phacoemulsification where procedure involves using an ultrasonic to dissolve the lens into small fragments and then aspirating (suck out) the contents of the lens and irrigate the eye.
Phacoemulsification method is quite popular as the incision is so small only 2.2 to 3.0 mm. so no stitches are needed. The artificial lens can be folded as well as less time for surgery so the vision becomes normal within a short period. The skillful ophthalmologist can perform surgery using only anesthetic drops in specific area, hence no need for injections or anesthesia so the surgery is safer. The lenses are designed as multifocal lenses with new technology enhancing the focus ability in all activities and light conditions. Your vision quality will be improved and become young again. Eye-glasses are not required anymore when reading, working on computers or driving.
Different types of artificial intraocular lenses (IOLs) are available for patients who have undergone surgical lens extraction. They are divided into two types depend on material used. The rigid lenses made from Polymethylmethacrylate (PMMA). This type of lenses cannot be folded and are widely used with ECCE method. The other type is soft lens which made from various materials such as Silicone or Acrylic. It can be folded and inserted through small incision so it is widely used with Phacoemulsification method. New type of artificial lenses are developed to solved the farsightedness problem using “Full Diffractive Design” technology that handle incoming light in a more sophisticated way, allowing for clear vision at multiple distances. No need to use eye-glasses anymore.
Ophthalmologist will decide which surgery method as well as type of lenses used for each patient to provide proper treatment.
