What Do You Understand By Cataract

 

cataract is an eye condition characterized by the clouding of the natural lens in the eye, leading to vision loss. Naturally, the eye's lens is clear and allows light to pass through, focusing on the retina at the back of the eye. but when a cataract develops, the lens becomes cloudy and interferes with the normal passage of light.

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.

Cataracts exhibit gradual 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:

Intraocular Lens Options

Laser-Assisted Cataract Surgery

In some cases cataract surgeons utilize advanced laser technology to assist with specific steps in eye cataract treatment, to enhance precision and efficiency in cataract removal. 

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 surgery.

Frequently Asked Questions

Yes it is possible. Now a days, with the availability of latest phaco refractive surgery techniques, one can get rid of specs for distance as well as near. Along with removal of cataracts, implantation of Toric, Multifocal and EDOF IOLs is performed in these procedures.

You can do without surgery until cataracts interfere with your daily life. However, if your cataract causes blurred vision, glare while driving, or make it impossible for you to complete tasks or enjoy hobbies, then it is time to consider surgery.

When you follow a healthy lifestyle and have a clean diet, the odds of cataracts getting worse may be reduced. By avoiding drugs that increase the risk of cataracts, you can also prevent cataract growth. It includes long-term use of certain eyedrops & medicines for skin and other ailments.As a final safety step, reduce prolonged UV light exposure without shielding your skin. Wear UV protective sunglasses to cut back on cataract growth, even during cloudy days.

Ageing is the most common risk factor related to cataracts. Some risk factors included: Smoking Certain diseases eg Diabetes Taking certain medications Extended unprotected exposure to UV rays
