Cataract
The natural lens of the eyes lets light pass through them onto the retina. The retina converts this light into signals and sends them to the optic nerve. The optic nerve sends the signals to the brain.
The proteins in the eye form clumps in the lens making it cloudy. This prevents the lens from sending clear images to the retina. Cataracts develop slowly and do not go away on their own. The only treatment for cataracts is surgery, where the natural lens of the eye is replaced with an artificial lens. Cataracts are classified according to the location and how they grow in the lens.
- Nuclear Cataracts start from the center of the lens
- Cortical Cataracts forms around the center of the lens
- Posterior capsular cataracts start from the back of the lens and grow swiftly
- Secondary cataracts are caused due to side-effects of medication such as steroids. Certain diseases, such as diabetes or glaucoma cause cataracts
- Traumatic cataracts occur due to injury or trauma
- Radiation cataracts occur due to exposure to high beams of radiation akin to radiation cancer treatments.
- Congenital cataracts are rare and affect infants at birth or form during the child’s first year
Symptoms of cataracts
It is time for a check-up of the eyes if:
- the vision is blurry
- it’s difficult to see at night
- if the colors seem faded
- there is increased sensitivity to bright lights
- there are rainbow hallows surrounding a light source
- there is double vision
- there is a change in prescription glasses frequently
Cataract Surgery
Cataract surgery is a simple operation lasting about 15 minutes and is done in daycare or as an outpatient procedure.
The most common modern cataract surgery is phacoemulsification. Local anesthesia (injected around the eye) or topical anesthesia (numbing drops) is administered first. A small incision is made at the edge of the cornea that creates an opening in the membrane surrounding the lens. A tiny ultrasonic probe is inserted through this incision. The probe vibrates at high speeds to break up the lens into fragments that are pulled out through the attachment at the tip of the probe.
After complete removal of the lens particles, the intraocular lens implant (IOL) is inserted through the incision with a hollow tube. After the lens is injected, it unfolds into the eyes and is positioned properly inside the eye capsule.
The incision heals completely in a few days. Post-operative care includes:
- caring for the eye
- avoiding heat, dust, and bright lights
- wearing dark glasses
- antibiotic drops
- steroids
- anti-inflammatory medicines
Eyesight should improve immediately after surgery and stabilize within 4 to 5 weeks.
Preventing Cataracts
It is possible to reduce the risks of developing cataracts by:
- Protecting eyes from harmful UV rays of the sun by wearing glasses
- Having regular eye exams
- Eating a healthy diet
- Exercising regularly
- Controlling medical conditions such as diabetes
- Maintaining a healthy weight
- No smoking
Conclusion
Cataracts reduce the quality of vision and can lead to blindness if left untreated. Some cataracts grow slowly and may stop growing altogether. However, they do not go away or become smaller on their own. Cataract surgery is a very common and highly effective procedure to treat cataracts.
