Cortical cataracts are one type of age-related cataract that is also common in patients with diabetes. A cortical cataract forms in the cortex, which is one layer of the eye's natural lens; these cataracts tend to look like spokes and can cause problems with decreased vision and glare. Cataract extraction is the definitive cure for a cortical cataract, but there are some other measures that a doctor might prescribe until the cataract is advanced enough for removal. There are no scientifically approved medications that can treat or heal cataracts.
Prescription Glasses
Since cortical cataracts can result in decreased visual acuity, the eye doctor may prescribe stronger glasses or bifocals to help a person with cortical cataracts see better, according to the All About Vision website. The progression of the symptoms of the cataract will influence how long the new glasses may work for the patient. Once stronger lenses are unable to improve the vision sufficiently for the person to function, other alternatives such as cataract surgery should be considered.
Tactics to Reduce Glare
As noted on the Kessler Optical website, the use of anti-glare coatings on the lenses of a pair of glasses may lower the amount of glare during night-time driving. Managing the levels of light used for reading and performing everyday tasks may also help patients manage problems with glare that may be caused by cortical cataracts.
Cataract Extraction Surgery
When the vision problems caused by the cortical cataract are too significant to be managed with new prescription strength glasses or anti-glare coatings, the treatment for a cortical cataract is cataract extraction and artificial lens placement in the eye. Cataract surgery is an outpatient procedure and involves the eye surgeon removing the cloudy lens of the eye in the operating room. The surgeon then places the artificial lens into the eye. The surgeon prescribes several eye drop medications for the patient to use at home and the patient generally will go home later that same day. The patient will then follow up with the surgeon as scheduled. Cataract surgery is effective at improving vision, and according to the All About Vision website, cataract surgery is the most common procedure in the United States.
