How To Tell If You Have Cataracts

Cataracts are a common condition that becomes more prevalent as we age. In fact, it’s estimated that by the age of 80, virtually everyone will either have cataracts or will have had surgery to have them removed.

But how can you tell if you have them? What are the signs and symptoms and what can be done about them?

Read on to discover more about the condition and the treatments that are on offer.

Cataract Symptoms and Diagnosis

Cataract symptoms 

Cataracts form very slowly over several years. However, in the early stages, they typically have no symptoms. They don’t cause pain, they don’t cause any vision issues, and the only way they can be diagnosed at this stage is by a comprehensive eye examination.

This makes it essential to go for regular checkups even if you have no symptoms or visual changes.

As the condition progresses, subtle changes begin to occur, and the condition starts to become symptomatic. These signs might include: 

• Sensitivity to light
• Reduced nighttime vision
• Seeing halos (rings) around a light source
• Gradual fading or yellowing in the vibrancy of colors
• Difficulty reading in low light
• Increased prescription changes

Cataract diagnosis

An ophthalmologist will diagnose cataracts with a comprehensive eye examination. This includes various types of tests such as:

• Tonometry: A way of measuring the fluid pressure within the eyes
• Slit-lamp examination: Allowing the doctor to observe the internal structures of the eye under magnification.
• Retinal exam: After placing drops in the eyes that cause the pupil to dilate, the doctor can use an ophthalmoscope to examine the lens more clearly.
• A visual acuity test: You’ll be asked to read a series of letters on a chart that decrease in size a line at a time. This will be carried out on each individual eye.

 There are other tests available if the doctor considers them necessary. However, these are the most common ones used.

Treatment Options: Cataract Eye Surgery

The different types of cataract eye surgery

There are two types of cataract surgery: traditional and laser. 

 Both have the same result, which is to replace the diseased lens with an artificial one. However, the procedure to do so differs.

 In traditional surgery, the surgeon uses a tiny scalpel to make a manual incision in the eye. A probe is then inserted behind the pupil and into the capsule that contains the lens. A special process is used to blast the lens into tiny pieces, and these are then suctioned out. The surgeon then places the artificial lens into the capsule and seals the incision using a special liquid.

With laser surgery, the same procedure is carried out, but it’s guided and performed via a computer program and laser. The unique pattern of the eye is mapped out using a special device. This determines not only the best location for the incision to be made but the exact depth that the new lens should be sited. In addition, if astigmatism is present, this can be carried out at the same time.

The benefits of laser treatment include the more accurate siting of the lens, meaning you can take advantage of the latest lenses on offer. It’s also faster than the traditional procedure and astigmatism can also be treated simultaneously.

 Your cataract surgeon will discuss which type of treatment is best for you and help you decide on the best artificial lens to insert for your lifestyle needs.
