Cataracts: Recognition, Diagnosis, and Treatment

Cataracts are an eye condition where the lens becomes cloudy, causing vision loss. As people age, the risk of developing cataracts increases. It is the leading cause of blindness worldwide.

Causes of Cataracts

• **Age-related **: Most common; lens gradually becomes cloudy with age.
• **Congenital **: Present at birth or during infancy
• ** Traumatic **: Caused by injury to the eye
• ** Concurrent **: Caused by other eye diseases or systemic conditions
• **Drug-induced **: Long-term use of certain medications (e.g., corticosteroids)

Common Symptoms

• Vision gradually blurs, as if looking through a fog.
• Light sensitivity and reduced night vision
• Double vision
• The color appears yellowed or darker.
• Insufficient light to read

Diagnostic Methods

• **Vision Exam**: Assess degree of vision loss
• **Slit-lamp examination of **: Assess lens opacity
• ** Eye Exam **: Rule out other eye conditions

Treatment Options

No medication can reverse cataracts. Surgery is the only effective treatment.

Phacoemulsification

• Minimally invasive surgery with incisions as small as 2-3 mm.
• Surgery duration: approximately 15-30 minutes
• Restore vision with an artificial lens implant
• Rapid postoperative recovery; most patients resume normal activities the following day.

### IOL Selection

• ** Single-focus lens **: Clear vision for distance or near, glasses required.
• ** Multi-Focal Lens **: See clearly at all distances, reducing dependence on glasses
• ** Astigmatism-Correcting IOL **: Corrects astigmatism simultaneously
