Opthalmic Microscope: Secondary Cataracts

Secondary cataracts are cataracts that are not brought about as a result of the aging process of a person. It is not a result of any prenatal malformation before birth either. This type of cataract can form after surgery for other eye problems, such as glaucoma.
An eye surgery utilizes an opthalmic microscope for clearer imaging.

Secondary cataract can also develop in people who have other health problems, such as diabetes, or as a result of deficiency in protein, such as the nutritional cataract.

Senile Cataracts

Senile cataract is the most common type of cataract. It is the kind of cataract that usually develops with a person’s age. The lens of our eyes grows all through out life. The lenses of our eyes are found to be growing in size as we age. There are major changes too in the clarity and resiliency our lenses. Later in life, our lenses will tend to become more rigid and less transparent. This is expected of everyone. This is normal as a result of the aging process, but the rate that it happens from one person to another varies. To verify the extent of the damage, the ophthalmologist may be in need of the assistance of an opthalmic microscope

Opthalmic Microscope: Cataract Symptoms

The most common symptoms of a cataract include cloudy, blurry, fuzzy, foggy, or filmy vision. Most cataract patients often commonly complain of too much glare, like when they are driving, from lamps, headlights, sunlight and other light sources. They might see these light sources as too bright compared to how a person with no cataracts could see them. As such, it is recommended that a patient sees an ophthalmologist for such problems. Surgery may be recommended and such would use the assistance of the instrument known as opthalmic microscope.

Opthalmic Microscope: Cataract Causes

There are numerous kinds of causes that trigger the development of cataracts. In most of the cases, they are one or more of the following factors associated with cataracts.

Age is the first factor. Most people when they age develop changes in their lenses, causing it to become rigid, hazy and cloudy. Age related cataracts are common.

Most cataract cases are found to be related to aging. Cataracts are very common in older people. The lens of the eye is normally clear, however, cataracts may also be present at or shortly after birth. These are referred to as congenital cataracts.

Severe cataracts can cause so many disabling effects in the patient’s life. Common cataract problems result to loss of independence for older adults as decreased vision may affect driving, working, reading, or just about anything they do everyday.

Opthalmic Microscope: Cataract

Generally speaking, cataract refers to any imperfection in the lens clarity of the eyes. It may be due to several reasons. More specifically, cataract is a painless clouding of the lens of the eye, which lies behind the structures called, the iris and the pupil.

The lens works by focusing light onto the retina at the back of the eye. The lens also adjusts the eye’s focus. Such is responsible for letting us see things clearly both up close and far away. The lenses in our eyes are mostly made up of water and protein. The protein is arranged in a specific kind of way that keeps the lens clear and allows light pass through it normally. But as we age, however, some of the protein may clump together. This clumping of protein could start to cloud a small area of the lenses of the eyes. This is then would result into a cataract.

Crystalline Lens

It is a scientific fact that our bodies, as we grow older, mature and change naturally. Within the aging eye, these changes often develop into conditions that impact the quality of your vision, related to clouding or infection or halo vision, we often need eyeglasses which works like a microscope. But if you are experiencing age related visual problems, with successful opthalmic treatment, it may be possible to have clearer, brighter and sharper vision than you have had for a long, long time. As the crystalline lens ages, it becomes harder and less flexible, and less able to change shape for near vision or accommodation. This process becomes clinically apparent at about age forty and continues until eye accommodation is lost, typically by age 65. Loss of accommodation of the lens is a normal aging process, known as presbyopia. Stronger reading glasses are necessary to compensate for the loss of ability to focus up close.
