Understanding Cataract: Learn About the Symptoms, Causes, and Available Treatments
Cataract is the leading cause of vision impairment in older adults, significantly impacting daily activities and quality of life. This condition develops gradually, causing blurred vision, glare sensitivity, and difficulty seeing at night. As cataract worsen, tasks like reading and driving become more difficult. Early detection and prompt treatment, particularly advancements in cataract surgery, can restore vision, improve independence, and enhance well-being. In this article, we discuss the key symptoms, causes, and the latest treatment options to help preserve vision and improve life quality.
What is Cataract?
Cataract is formed when the lens starts getting cloudy and loses its transparency. This cloudiness affects the overall seeing, disturbing it and causing blurry vision or simply making everything look less clear through glares. Cataract can develop in one eye or both eyes and regular exams will help us identify it. However, cataract is generally associated with aging; and use of certain drugs, hereditary diseases, and trauma can lead to earlier development of cataract. Phacoemulsification is an advanced cataract removal technique which is available in Aarya Eye Care for restoration of vision, making cataract surgery the most common and successful medical procedure today.
Types of Cataract
Cataract come in several types, each affecting the lens differently and affecting vision in distinct ways. Understanding these types can aid in early detection and personalised Cataract Surgery treatments. Here are the primary types:
- Nuclear Cataract: Develop in the center of the lens, causing near-sightedness initially, and may progress to a yellow or brown lens discoloration.
- Cortical Cataract: Form around the edges of the lens cortex, creating white, wedge- like opacities that gradually move toward the lens center.
- Posterior Subcapsular Cataract: Develop at the back of the lens, which leads to glare and halos around lights.
- Congenital Cataract: Present at birth or develop during childhood due to genetic factors or developmental issues.
What are the Symptoms of Cataract?
The symptoms of cataract may vary based on the severity and the type, but it includes general vision impairment that affects daily activities. Recognising these symptoms early is key to managing cataract effectively through advanced cataract surgery.
The common symptoms include:
- Blurred Or Cloudy Vision
- Sensitivity To Light And Glare
- Difficulties Seeing At Night
- Colour Fading Or Yellowing
- Frequent Prescription Eyewear Changes
- Double Vision in One Eye
What Really Causes Cataract?
Cataract can develop due to several factors, from natural aging processes to lifestyle choices and certain medical conditions. These factors can lead to protein breakdown in the lens, resulting in cloudiness. Major cataract causes are aging, medical conditions, eye injuries, etc.
- Aging: Most cataract are age-related, but changes caused by aging do not always lead to cataract.
- Medical conditions: Especially diabetes can accelerate cataract formation when the blood sugar levels are above the safe range.
- Eye injuries: it is a rare case but trauma to the eye can cause cataract to develop sooner.
- Lifestyle factors: Smoking, alcohol use, and UV exposure increase risk.
- Medication side effects: Certain medications, especially steroids, may contribute.
Who Is at Risk for Cataract?
Certain groups are more likely to develop cataract. Understanding these risk factors can encourage preventive measures and prompt medical check-ups.
- Age: Cataract are most common in people over the age of 60.
- Genetics: Family history of cataract increases susceptibility.
- Medical Conditions: Diabetes and hypertension are significant risk factors.
- Lifestyle Factors: Smoking, excessive alcohol, and UV exposure raise the likelihood.
- Nutritional Deficiencies: Lack of antioxidants in the diet can affect eye health.
- Eye Injuries: Trauma and chronic inflammation can lead to cataract formation.
How to Reduce Risks of Cataract?
Not all cataract can be prevented, but following some lifestyle adjustments can reduce the risk. Prioritising eye health with regular check-ups, a nutritious diet containing antioxidants and protective measures against UV exposure can make a difference.
- Regular Eye Exams : Early detection, annual eye examination can help in detecting early signs of cataract.
- Healthy Diet: Following a diet rich in antioxidants, like vitamins C and E, supports eye health.
- Protect Your Eyes : Wear sunglasses with UV protection to prevent lens damage because years of excessive exposure to the sun and UV rays are harmful for eyes.
- Quit Smoking : Avoiding smoking can greatly reduce cataract risk.
- Manage Medical Conditions : Control diabetes because cataract can form earlier if you have diabetes, hypertension, and other conditions that may contribute to cataract formation.
How to Diagnose Cataract
Diagnosing cataract involves a detailed eye examination, including vision tests and specialized tools to examine the lens. For the detection of cataract, doctors can identify lens cloudiness by slit- lamp examination. If a cataract is detected, additional tests assess the extent of vision impairment and decide on treatment, such as cataract surgery. Aarya Eye Care offers advanced diagnostic facilities to ensure precise results and specific treatment plans.
How to Treat Cataract: Solutions for Clearer Sight
Surgery is the only effective solution for correcting vision and preventing further vision loss due to the cataract. During cataract surgery, an ophthalmologist emulsifies the nucleus of the eye that has become cloudy and implants an artificial IOL. This IOL is a permanent, synthetic vision- correcting implant that replaces a lens of the affected eye and clears the cataract-induced vision difficulties. Multifocal and extended depth of focus (EDOF) are both intraocular lenses that help to improve the quality of vision. Multifocal lenses provide clear vision at multiple distances like near, intermediate, and far, reducing the need for glasses, while EDOF lenses extend the range of focus, offering improved intermediate and distance vision with minimal visual disturbances.
