What is a cataract?
A cataract is a general clouding that develops in the midsections of the crystalline lenses of the eyeballs. Cataracts can vary is severity from quite mild to causing complete opaqueness. Light rays are obstructed from entering the eye for processing and the result is disrupted vision that worsens over time.
Cataract surgeries are some of the safest and most performed eye enhancement operations across the planet.
A step-by-step guide to cataract surgery:
First, the surgeon will create a very entry point at the outer edge of the cornea;
Entry point is only big enough for surgical instruments to be able to fit through;
After making the entry, the surgeon gently peels away the top layer of the lens;
This allows access to the inner areas of the lens where the cataract has developed;
Next, the cataract is broken into smaller segments and removed with a special surgical tool like an ultrasound;
A replacement lens is inserted into the space where the natural lens used to be;
There are various types of advanced lens that can be used. These lenses have the ability to correct distance, near and intermediate vision also there is a lens that can correct astigmatism.
Many patients are able to reduce their need for glasses after cataract surgery with the availability of advanced lenses that are multi-focal (distance, near and intermediate vision).
The entry point is so small that it is often watertight and requires no suturing whatsoever;
Healing is rapid and complications are rarely experienced.
Other facts about cataracts and cataract surgery:
Early cataract development may cause a shift in prescription, such as increased myopia (nearsightedness);
The gradual "yellowing" associated with cataract development often causes patients to ineffectively perceive blue hues and white paper often looks dingy;
The condition most often affects both eyes, although one eye normally is affected before the other;
Left untreated for too long, cataracts can and do cause a dramatic decrease in vision;
Cataract surgery is a safe, cost-effective method to alleviate the debilitating symptoms of cataracts. It's advisable to consult with a cataract surgeon and make sure that all of your questions and concerns are addressed prior to committing to the procedure.
