What do you understand by Cataract?
What's Your Speciality
Cataracts are categorized based on their cause and location.
- Nuclear cataracts form in the central part of the eye’s lens, affecting vision.
- Cortical cataracts develop in the lens cortex, causing visual disturbances.
- Posterior subcapsular cataracts occur at the back of the lens, impacting close-up vision and reading.
- Congenital cataracts are present at birth, often due to genetics or maternal infections during pregnancy.
- Traumatic cataracts result from eye injuries.
- Secondary cataracts may develop as complications of other eye conditions or surgeries.
- Age-related cataracts occur due to natural aging, it makes a cloudy area on the lens and impairs or harms vision.
Cataract Symptoms that affect vision.
- Blurred or cloudy vision
- Increased sensitivity to glare
- Difficulty seeing at night,
- Fading and yellowing of colors.
- Frequent changes in eyeglass prescription
- Double vision in one eye and a halo effect around lights
- Decrease contrast sensitivity, leading to difficulty distinguishing between objects
- Additionally, individuals may experience a decline in visual acuity, making routine activities such as reading or driving challenging.
Cataracts develop when the eye’s natural lens becomes cloudy, typically due to aging. Proteins in the lens break down and clump together, causing opacity. Aging is the primary factor, as cumulative damage occurs over time. Other contributors include:
- Prolonged exposure to ultraviolet radiation
- Smoking
- Diabetes
- Certain medications.
- Genetic factors
- Trauma
- Eye injuries
- Inflammatory conditions increase the risk
- Excessive alcohol consumption
- Poor nutrition
- Lack of antioxidants like vitamins C and E
- Managing risk factors and adopting a healthy lifestyle can mitigate the likelihood of cataract formation.
Treatments for Cataract
Surgical Options:
- Phacoemulsification: A most common and modern technique for cataract eye surgery. It involves using ultrasound energy to break up the cloudy lens into small fragments, which are suctioned out of the eye.
- Extracapsular Cataract Extraction (ECCE): In this traditional method, the surgeon removes the entire lens in one piece. Phacoemulsification is more common today due to its smaller incisions and faster recovery.
Intraocular Lens Options
- Monofocal IOL: This lens type provides clear vision at a single focal distance, typically for distance vision. Glasses may be needed for reading or other tasks.
- Multifocal IOL: These lenses are designed to provide clear vision at multiple distances, reducing the need for glasses after surgery.
- Toric IOL: Corrects astigmatism in addition to cataracts.
- Accommodative IOL: Mimics the natural lens’ ability to shift focus between near and far distances.
Laser-Assisted Cataract Surgery
Cataract surgeons sometimes utilize advanced laser technology to assist with specific steps in eye cataract treatment, enhancing precision and efficiency in cataract operation.
A femtosecond laser creates precise incisions, fragments the cloudy lens, and facilitates its removal. This method offers improved accuracy, reduces the need for manual steps, and enhances overall surgical outcomes, leading to quicker recovery and improved visual results for patients undergoing cataract eye surgery.
What Our Patient Say About Our Caring
My mother had her eye surgery done here. The entire process was smooth and the doctor explained everything clearly. Now she can see perfectly. Thank you, Devisha Netra Chikitsalaya!
I was really nervous before my cataract surgery, but the doctors here made me feel so comfortable. They are very experienced and caring. I highly recommend this hospital to everyone
After struggling with poor vision for years, I finally decided to consult Devisha Netra Chikitsalaya. The treatment changed my life! Now I can read, drive, and do everything clearly again
