Waiting for a Cataract Surgery? Here are some Basic Stuff to Know

Ophthalmology has advanced largely over the last few decades and many of the troublesome eye and vision pathology can be now corrected through non- or minimally invasive procedures.

Cataract surgery is a very common procedure among these, which  everyone may have heard about. But, when it comes to you being placed on the cataract surgery table, people tend to get nervous about it. For those have impending cataract surgery, here we will just have an overview of it to alleviate your fear.

What is cataract?

What makes vision possible to us is s small lens located inside our eyes. Just as in case of a camera, the eye lens helps us to focus properly on things at different distances and enjoy a complete visual experience. In order to work properly, these lenses must be fully clear and functional. But, as people age, the lens may tend to become cloudy. This condition is called cataract. The result of cataract is blurred vision as you are seeing things through fog.

Cataract is identified as the major cause of vision loss in people above 55. The basic symptoms of cataract development are blurry vision, dullness or fading of colored, impaired night vision, light sensitivity etc. The major risk factors to develop cataract include trauma to eye, diabetes, burns, injury, toxins such as tobacco or alcohol, constant exposure to radiation, hypothyroidism etc. Heredity is also a risk factor to cataract.

Cataract surgery

Cataract surgery is a simple day surgery procedure, which is conducted at most of the surgical center and hospitals. The course of the prep and surgery may last for about three hours. Anesthesia given while performing cataract surgery is primarily topical anesthesia with dilating drops. An IV line may also be placed during the procedure. An expert surgeon will then accomplish the procedure in the following steps;

Step 1: Once after the local sedation is accomplished, the surgeon will make a small incision to gain access to the cloudy lens. A tiny instrument (as small as one-eighth of an inch or smaller) will be entered into the eye will be then used to break the cataract into small pieces so as to easily remove with the help of a mini vacuum cleaner.

Step 2: A new lens will be then implanted into your eyes. The surgeon will conduct a final check to ensure excellent positioning of the lens. The lid support speculum will be removed once after ensuring the wound is watertight.

Step 3: The patient will be moved to the postoperative holding area to be monitored for a few hours before discharging. You can view a number of cataract surgery videos online to see how it is done.

Your new lens

The new lens implanted during cataract surgery is an artificial lens, which is primarily made of plastic-like materials. Similar to your natural eye lens, the newly implanted lens can help restore your eyes’ ability to adequately focus. These artificial implants now come in different strengths and features. Experts will perform various tests and measurements to identify which is the most appropriate lens suited to your eyes.
