Let's Understanding what is Cataract
A cataract is an eye problem where there is clouding of the normally clear lens of your eye. People having cataracts generally feels like seeing through cloudy lenses or is a bit like looking through a frosty or fogged-up window. Clouded vision caused by cataracts can make it more difficult to read, drive a car (especially at night) or see the person’s face clearly.
This generally occurs when proteins build up and form a cloudy layer on the lens. This protein build up gradually develops and starts interfering with your vision and unless treated could lead to total blindness.
Symptoms of Cataract
Common symptoms of cataracts include:
- blurred or cloudy vision
- trouble seeing at night
- seeing colors as faded
- increased sensitivity to glare or sunlight
- halos surrounding lights
- double vision in the affected eye
- a need for frequent changes in prescription glasses
- a need for brighter reading light
Causes of Cataract
There are several underlying causes of cataracts. These include:
- the long-term use of steroids and other medications
- certain diseases, such as diabetes, hypertension
- long exposure to sunlight
- ultraviolet radiation
- hormone therapy treatment
- radiation therapy
Types of Cataract
- Nuclear cataract –This is the most common type of cataract. Nuclear cataracts forms with old ages and the lens of the eyes gets cloudy/blurred and might turn yellow. Over time, this yellowish tint can turn brown impacting your visual and making it hard to read and differentiate between various colours.
- Posterior Sub capsular cataract – hese cataracts form in the back of your eyes and they tend to progress much faster. Most of the time this type of cataract makes the eyes sensitive to light and seeing halos and glares around bright lights becomes common.
- Cortical cataract – This cataract starts at the periphery or sides of the lens with white opacities that gradually progresses inwards towards the center. The vision can be impaired depending on the position of the white opacities.
- Senile cataract –This type of cataract is the most common reason for treatable blindness. It is generally formed with the advancement of age. It is mostly characterized by the gradual progression of visual deterioration, clouding and thickening of the lens.
- Rosette cataract –This is a type of traumatic cataract which is associated with blunt injury to the eye. Rosette or stellate-shaped cataracts can sometimes also be associated with diabetic patients.
- Intumescent cataract – This type of cataract generally progresses and makes the lens to swell. This might even lead to acute glaucoma
Risk Factors associated with Cataract
Risk factors associated with cataracts include:
- older age
- heavy alcohol use
- high blood pressure
- previous eye injuries
- a family history of cataracts
- too much sun exposure
- exposure to radiation from X-rays and cancer treatments
Treatment for Cataract
Cataract are eye problems which are commonly inferred to as completely treatable. Surgery is recommended when cataracts prevent you from going about your daily activities, such as reading or driving. If you’re unable or uninterested in surgery, your doctor may be able to help you manage your symptoms. They may suggest stronger eyeglasses, magnifying lenses, or sunglasses with an anti-glare coating.
The different types of surgeries or procedures for treating cataract are:
- Device producing ultrasound waves – Sometime a device that produces ultrasound waves may be inserted. These waves help in breaking the cloudy lens. Thereafter the broken particles are removed and an intraocular lens (IOL) is implanted in the natural lens capsule.
- Extra capsular surgery –This is also known as large-incision surgery where a larger cut is made so that the entire affected part can be removed in one piece. Thereafter it is replaced with an intraocular (IOL) lens.
- Femtosecond laser surgery –This is a technology aided, computer-guided laser cataract surgery wherein treatment that is programmed by the surgeon to break up the affected lens.
