Cortical Cataracts occur when one’s eye lens becomes cloudy due to excess water and clumping of proteins.

As time passes, the Cortical Cataract gets closer to the center and causes vision problems.

It is a common age-related condition that affects many individuals around the world.  

The article explores more about Cortical Cataracts, its symptoms, causes, stages, and various treatment options.

Cortical Cataracts symptoms

Cortical Cataract is a specific type of Cataract that affects the edges of one’s eye lens.

The eye lens is present behind the iris and helps focus light on the retina. 

The Cortical Cataract affects the top layer of the lens and may affect one’s vision. 

The patients may not notice any symptoms in the early Cataract stage.

However, as the Cataract gets more severe, one may notice the following symptoms:

  • Blurry vision
  • Glare sensitivity
  • Double vision
  • Difficulty in telling the distance of objects
  • Appearance of white lines like spokes
  • Trouble while looking at bright light

Cortical Cataracts can also impact contrast sensitivity and make it difficult to distinguish between shades of color.

Consult a doctor if you experience any of the above symptoms.

Consult a doctor for frequent changes in eyeglasses or contact lens prescriptions, as Cortical Cataracts can affect the eye’s ability to focus properly.

Cortical Cataract treatment options

The treatment of Cortical Cataracts depends on its severity and how it affects one’s daily life. 

Mild early-stage vision loss can be treated by changing the prescription for glasses. 

Also, lifestyle choices like reducing night driving and using anti-glare eyewear may also help the eye condition.

However, the doctors may suggest different Cataract surgery like Phacoemulsification and Femtosecond Cataract surgery for advanced Cortical Cataract cases. 

Phacoemulsification is a common Cataract surgery that uses ultrasonic vibrations to break up and remove the cloudy lens.

On the other hand, Femtosecond Cataract surgery uses laser technology for precise cuts to improve the accuracy of the process. 

The surgical options replace the natural cloudy lens with a clear artificial lens.

Consult an eye expert before choosing any Cataract treatment option.
