Cataracts Causes, Symptoms, Vision Tests, and Surgery

What Are Cataracts? 

Cataracts are a painless clouding of the internal lens of the eye. Because they block light from passing through the lens, cataracts make it difficult to see clearly and can even cause blindness over time. Cataracts are progressive, meaning they worsen with time. Most cases occur in older people, but sometimes they can be seen in younger people as well.

How Your Vision Is Affected By Cataracts

Light enters the eye and passes through the lens. The lens of the eye focuses light onto the retina, which transmits visual signals through the optic nerve to the brain. Clouding of the lens due to cataracts results in blurring of the images you see. Other problems with the eyes can also cause blurry vision, but cataracts produce some characteristic symptoms.

Cataract Symptom: Blurry Vision

 The most common symptom of cataracts is seeing blurry images at any distance. People may describe their vision as foggy, cloudy, or filmy. Cataracts get worse with time, and less light reaches the retina. It may be especially hard for people with cataracts to see and drive at night.

Cataract Symptom: Glare

 Glare, or sensitivity to light, is another symptom of cataracts. It can be difficult for a person with cataracts to see in bright sunlight. Indoor lights may begin to seem too bright, or they may appear to have halos around them. Glare from oncoming headlights can cause problems with driving at night.

Cataract Symptom: Double Vision

Diplopia, or double vision, when looking with one eye can be another symptom of cataracts. This is not the same as diplopia that arises from improper alignment of the eyes. The double vision seen with cataracts occurs even when you look through only one eye.

Cataract Symptom: Color Changes

Cataracts also affect color vision. Some colors may appear faded, and things may acquire a yellowish or brownish tint. This may not be noticed at first, but with time, distinguishing between blues and purples can be difficult.

Cataract Symptom: Second Sight

The phenomenon known as "second sight" is another characteristic of cataracts. In this situation, the cataract acts as a stronger lens, temporarily improving the ability to see things at a close distance. People who formerly needed reading glasses may no longer need them. However, as the cataract worsens over time, this temporary improvement in near vision disappears.

Cataract Symptom: New Prescription

People with cataracts often need frequent changes in their eyeglasses or contact lenses because their vision deteriorates over time.

Who Can Get Cataracts?

Most cataracts occur in older people and are related to the aging process. Over half of Americans over 65 have cataracts. Sometimes, babies can be born with cataracts, known as congenital cataracts. Uncommonly, children can get cataracts as a result of illness or trauma to the eye.

What Are the Causes of Cataracts?

It is not precisely understood why people get cataracts. Aging is a known risk factor. Other factors that may also play a role in the development of cataracts include:

  • Smoking
  • Excessive use of alcohol
  • Diabetes
  • Trauma to the eyes
  • Extended use of corticosteroids
  • Prolonged radiation or sun exposure
How Are Cataracts Diagnosed?

Cataracts can be diagnosed with an eye exam. The eye exam contains a vision test and an examination of your eyes using a slit lamp microscope. The pupils are dilated with special eyedrops to provide a better view of the back of the eye, where the retina and optic nerve are located.

Cataract Surgery

Surgery to remove cataracts may be required if the related vision loss cannot be corrected with glasses or contact lenses. Cataract surgery involves removing the cloudy natural lens and replacing it with an artificial lens. The operation is usually done on an outpatient basis and is very safe and effective. For those who need surgery on both eyes, the surgery is usually done on one eye at a time.

LASIK EYE SURGERY IN INDORE:

WHAT IS LASIK? Laser In-Situ Keratomileusis(LASIK), is a surgical procedure which is used for correction of vision in people suffering from refractive defects such as Myopia(Near-sightedness), Hypermetropia(Far-sightedness), and Astigmatism(Corneal Defect). LASIK surgery provides reduction in the power or even freedom from spectacles to the patients and is of great aid in gaining self-confidence as well. LASIK is now one of the most common surgical procedures around the world and is widely used for correction of refractive disorders. It is an outpatient surgical procedure that takes around 10-15 minutes for each eye and the patient is able to see again within hours after the surgery. The actual laser exposure is less than a minute for each eye. HOW DOES LASIK WORK? LASIK works on the principle of sculpting and remodelling of cornea using Excimer Laser(an ultraviolet laser) which delivers the laser correction(Photoblation) into the thickness of cornea.

How to Find the Right Contact Lenses

Contact lenses have come a long way and offer some exciting options. You can bat a pair of baby blues one day, then flash golden tiger eyes the next. You can even toss disposable lenses in the trash each night. For people with vision problems, contacts remain an effective, almost invisible tool. The thin plastic lenses fit over your cornea -- the clear, front part of your eye -- to correct vision problems including nearsightedness, farsightedness, and astigmatism. You can wear contacts even if you have presbyopia and need bifocals. Talk to your eye doctor about the best type of lenses for you. Get regular eye exams to keep your peepers healthy and make sure your prescription stays up to date. Soft Contact Lenses They’re made from a special type of plastic mixed with water. The water content lets oxygen pass through the lens to your cornea. That makes the lenses more comfortable, lessens dry eyes, and helps keep your cornea healthy. If it doesn't get enough oxygen

What are the different types of intraocular lenses implanted after cataract surgery?

Image
As the natural lens plays a vital role in focusing light for clear vision, artificial-lens implantation at the time of cataract surgery is necessary to yield the best visual results. Because the implant is placed in or near the original position of the removed natural lens, vision can be restored, and peripheral vision, depth perception, and image size should not be affected. Artificial lenses are intended to remain permanently in place, require no maintenance or handling, and are neither felt by the patient nor noticed by others. There are a variety of intraocular lens styles available for implantation, including monofocal, toric, and multifocal intraocular lenses. Monofocal lens: These lenses are the most commonly implanted lenses today. They have equal power in all regions of the lens and can provide high-quality vision at a single focal point (usually at distance). They usually require only a light pair of spectacles for optimal distance vision correction. However,
