Cortical cataracts are a kind of cataract that develops in the edges of the lens and then make their way towards the center in a spoke-like manner. A cortical cataract occurs in the edges of the lens – the cortex – hence the name cortical cataracts.
As the condition of the cortical cataract worsens, the light entering the eye is scattered, causing a hazy vision. Cortical senile cataract progress in two manners — they either develop slowly and stay the same for a long period or progress very rapidly.
There are two varieties of cortical cataract – posterior cortical cataract, and anterior cortical cataract.
Posterior cortical cataract is when the opacity develops in the layer that is right under the lens capsule. Similarly, anterior cortical cataract occurs in the front of the lens capsule, or inside it. It generally occurs due to a head or eye injury, rather than simply develop over time.
Hazy vision
Severe glare from sources of light
Difficulty in telling similar colours apart
Difficulty in judging how far an object is placed
Possible double vision in the affected eye – monocular diplopia
Some of the key causes of cortical cataract are:
Progressing age
Any eye injury
History of cataract in the family
Apart from the general causes, some of the risk factors which could to cortical cataract include:
Lifestyle diseases such as diabetes, hypertension
Severe myopia
Smoking
While preventing the development of cortical cataracts may be difficult, you can reduce the risk factors by taking the following steps:
Stop smoking
Protect yourself from harmful UV rays while stepping out
Get your eyes tested regularly
Keep diabetes and other lifestyle-related disorders under check
A doctor looking to treat a person for cortical cataracts will undertake three tests predominantly.
These are:
Also known as the generic ‘reading test’, the test requires the patient to read a set of letters in varying sizes from a fixed distance.
The doctor uses a special microscope-like device with a light on it to examine different parts of the eye – the cornea, iris, and the lens, which is where the cataract is bound to develop.
The doctor administers drops into the patient’s eye to widen the retina. Once the eyes are adequately dilated, the doctor examines the retina along with the cataract to detect any abnormalities.
While surgery is often the chosen for cortical cataracts treatment, early stages of the disorder can be managed with prescription glasses. Getting spectacles with a stronger lens will help make the vision better for a while.
However, one cannot put off surgery for too long. While there are several kinds of procedures to resolve cataract, the method in every procedure remains the same — the cloudy lens is replaced with a normal lens to make the vision clearer. The procedure usually lasts 15 to 20 minutes and does not require admission to a hospital.

Typical symptoms of cortical cataracts include blurred vision, glare, difficulty seeing in bright light, and changes in color perception.
Cortical cataracts develop when the lens of the eye undergoes changes in the lens cortex, resulting in opacity or cloudiness.
Risk factors associated with cortical cataracts include aging, diabetes, smoking, prolonged exposure to sunlight, and certain medications like corticosteroids.
Cortical cataracts are distinguished by the presence of opacities in the lens cortex, which can appear as wedge-shaped or spoke-like patterns radiating from the periphery of the lens towards the center.
Diagnostic procedures used to identify cortical cataracts include visual acuity tests, slit-lamp examination, and dilated eye examination by an ophthalmologist.
Treatment options for cortical cataracts at Dr. Agarwals may include prescription eyeglasses, contact lenses, or surgical intervention such as phacoemulsification with intraocular lens implantation.
