Study Notes
Cataract
Symptoms
- Blurry or cloudy vision
- Double vision or ghosting
- Sensitivity to light
- Difficulty seeing at night or in low light
- Fading or yellowing of colors
- Need for brighter light to read or perform tasks
- Difficulty seeing details or small print
- Difficulty driving at night due to glare from oncoming headlights
Treatment Options
- Surgery: removal of the cloudy natural lens and replacement with an artificial lens called an intraocular lens (IOL)
- Glasses or contact lenses: to correct vision problems caused by cataracts
- Anti-glare sunglasses: to reduce glare and discomfort
Surgery
- Phacoemulsification: a small incision is made in the cornea, and a probe is inserted to break up the cloudy lens using ultrasonic waves
- Extracapsular surgery: the cloudy lens is removed in one piece, and the IOL is inserted through a smaller incision
- Laser-assisted cataract surgery: uses a laser to create the incision and break up the cloudy lens
Types
- Nuclear cataract: affects the center of the lens
- Cortical cataract: affects the outer layer of the lens
- Posterior subcapsular cataract: affects the back of the lens
- Congenital cataract: present at birth or develops during childhood
- Traumatic cataract: caused by injury to the eye
- Secondary cataract: develops after eye surgery or certain medical conditions
Causes
- Aging: most common cause
- Injury or trauma: can cause cataract formation
- Genetics: inherited disorders or family history
- Diabetes: high blood sugar can cause cataracts
- Medications: certain medications, such as steroids, can increase the risk of cataracts
- Radiation: exposure to radiation can cause cataracts
Symptoms of Cataracts
- Blurry or cloudy vision due to the cloudy natural lens
- Double vision or ghosting, making it difficult to see clearly
- Sensitivity to light, causing discomfort or pain
- Difficulty seeing at night or in low light conditions
- Fading or yellowing of colors, affecting color perception
- Need for brighter light to read or perform daily tasks
- Difficulty seeing details or small print, straining the eyes
- Difficulty driving at night due to glare from oncoming headlights

Cataract Symptoms
- Cloudy or blurry vision is a common symptom of cataracts
- Double vision or ghosting is a symptom of cataracts that can interfere with daily activities
- Sensitivity to light or glare can be a symptom of cataracts, making it difficult for people to adapt to changing light conditions
- Fading or yellowing of colors can be a symptom of cataracts, affecting color perception
- Difficulty seeing at night can be a symptom of cataracts, making it hazardous to drive or navigate in low-light environments
- The need for bright light for reading or other activities can be a symptom of cataracts, revealing difficulty with visual acuity
Surgery
- Phacoemulsification is the most common type of cataract surgery, using ultrasound waves to break up the cloudy lens
- Extracapsular cataract extraction is an alternative to phacoemulsification, where the cloudy lens is removed in one piece
- Intraocular lens implantation involves implanting an artificial lens in the eye to restore vision
Causes
- Aging is the most common cause of cataracts
- Injury or trauma to the eye can cause a cataract
- Genetics can also play a role, with some people being born with cataracts or developing them at a young age
- Certain medical conditions, such as diabetes, hypertension, and obesity, can increase the risk of cataracts
- Long-term use of corticosteroids can increase the risk of cataracts
- Exposure to radiation therapy can also increase the risk of cataracts
Types
- Nuclear cataracts occur when the center of the lens becomes cloudy
- Cortical cataracts occur when the outer layer of the lens becomes cloudy
- Posterior subcapsular cataracts occur when the back of the lens becomes cloudy
- Congenital cataracts are present at birth or develop during childhood
- Secondary cataracts develop after eye surgery or other medical conditions
Treatment Options
- Surgery is the most effective treatment for cataracts
- Glasses or contacts can improve vision but cannot reverse the cataract
- Anti-glare glasses can reduce glare and improve vision
- Magnifying glasses can improve near vision
