Cataracts: Causes, Symptoms, and Modern Treatment Options

Causes of Cataracts

Several known factors can contribute to the development of cataracts.

Age-Related Cataracts

Most cataracts are age-related, developing gradually over the years. The human lens is made mostly of water and proteins. As we age, some of these proteins cluster together, causing clouding in small areas.

Congenital Cataracts

Congenital cataracts are present from birth or form in a baby's first year. These cataracts are typically caused by an infection or disease the mother had during pregnancy, or they can be inherited.

Traumatic Cataracts

Traumatic cataracts form after an injury to the eye. The better you can protect your eyes from injury, the lower your risk.

Common Symptoms and Impact

Often, in the initial stages, cataracts have little effect on vision. Symptoms progress over time and can include blurry vision, diminished night vision, increased sensitivity to light and glare, needing brighter light for reading, and seeing "halos" around lights. This can affect daily tasks such as driving, especially at night, reading, or even recognizing faces.

Diagnosis and Evaluation

Cataracts are usually diagnosed with an eye exam. Your doctor will review your medical history, perform a visual acuity test, and conduct a dilated eye exam. Once cataracts are detected, your healthcare provider can gauge the extent of the cataract development and any accompanying conditions for comprehensive treatment.

Modern Treatment Options

When cataracts interfere significantly with vision, doctors often recommend cataract surgery, during which the foggy lens is removed and replaced with an artificial one called an intraocular lens (IOL). Intraocular Lens (IOLs) options include the following.

• Monofocal IOLs that offer vision correction at a single distance (near, intermediate, or far)
• Multifocal IOLs that provide vision correction at multiple distances
• Accommodating IOLs that adjust their position in the eye, allowing for clearer vision at different distances.

Modern technological advancements have paved the way for procedures like Phacoemulsification and Femtosecond Laser-assisted cataract surgery. Both involve tiny incisions and quick recovery times.

Recovery and Aftercare

Recovery from cataract surgery is generally quick, with many resuming most of their normal activities within a day or a few. Post-surgery, patients might need to use eyedrops containing antibiotics and anti-inflammatory drugs. It's also crucial to avoid any strenuous activity or anything that might put pressure on your eye while you recover.
