What Is cataract? 5 Things to Know About It


Clouding of the eye lens, i.e., cataract formation, is common in older people. The most common kind is age-related cataract. It’s of three types, nuclear sclerotic, cortical, and posterior subcapsular. Glare around lights and blurred eyesight are its symptoms. Cataract surgery entails removing your clouded lens and replacing it with a clear artificial lens known as an IOL. When cataract problems interfere with everyday life, your cataract doctor may prescribe surgery. Read on to know what is cataract and what you need to know about them.

What Is Cataract?

A cataract is a condition wherein clouding of the eye lens takes place. Cataract patients compare gazing through a fogged-up window to seeing through clouded lenses. Cataracts can cause cloudy vision, making it difficult to read, drive a car (particularly at night), or visit the expression on a friend's face.

Most cataracts form slowly and do not interfere with your vision initially. But, on the other hand, it will ultimately impair your eyesight. Stronger lighting and spectacles might help you deal with cataracts at first. However, you may require surgery if your vision interferes with your daily activities. Cataract operation, fortunately, is often a safe and successful cataract treatment.

5 Things To Know About Cataracts

Cataracts are commonly associated with age-related loss of vision. They appear when the lens becomes hazy. This cloudiness results from proteins in the retina clumping together over time. Cataracts cause vision blur, glare, and nearsightedness. Many individuals consider cataracts to be an unavoidable annoyance that comes with age. But there's a lot more to cataracts that everyone is unaware of.

You Can't Avoid Cataracts But Can Reduce Its Risk

Cataracts affect over half of the population above the age of seventy. The eyes age like the rest of the body resulting in the development of cataracts. They are normal with ageing, and no known technique exists to avoid them.

According to research, a healthy lifestyle might minimise your chances of having cataracts. This includes eating healthy, exercising, and minimising UV exposure. There is no surety that you will not get cataracts, but you can minimise your chances by making these decisions.

Cataracts Can Occur At Any Age

Cataracts are commonly associated with the elderly. However, they can arise at any age. Cataracts do not form overnight. Instead, they may develop while you are as young as forty. Most individuals are unaware they have cataracts until their vision begins to deteriorate. If you have diabetes or eye injuries, you may acquire cataracts before age forty.

Activities Have No Effect on Cataracts

Cataracts, like most medical issues, are flush with falsehoods. One common misconception is that straining your eyes causes cataracts to form faster. This implies that jobs requiring near eyesight, such as stitching or reading, harm your eyes. Fortunately, this is a myth! A cataract occurs in the lens, not due to your activities. When you work up close, your ability to notice a low-light contrast suffers.

Common Treatment Is Cataract Surgery

Cataract surgery is not for everyone; however, it is highly recommended. Cataract surgery can help restore and enhance eyesight. An IOL replaces the lens of the eye during cataract surgery. An IOL, or artificial intraocular lens, performs the lens function. Cataract surgery may be inconvenient, but it is one of the most frequent treatments! It is safe and successful in restoring the vision that cataracts have taken away.

Cataracts Do Not "Grow Back" after Cataract Surgery.

Some patients may be concerned that their cataracts may return after surgery. A cataract cannot form when the lens is replaced with an IOL. Because an IOL is not composed of biological tissue, it cannot become blurred. A "secondary cataract" can, however, form after cataract surgery. This is additionally referred to as clouding around the IOL. If this occurs, it is curable with a small operation that takes around 15 minutes.

Treatment Options

Many cataracts are unnoticeable and cause few symptoms. In that case, no surgical therapy is required. Surgery is the only effective therapy for cataracts when prescription glasses are no longer functional. When your cataracts begin to compromise your ability to conduct routine everyday tasks, such as reading or driving at night, physicians recommend cataract surgery.

Patients' symptoms of a cataract differ. A cataract in only one eye is bothersome to one but does not produce major symptoms in another. Cataracts rarely cause injury to the eye, so you can undergo surgery whenever convenient for you.

Because the eye's lens is required to focus light onto the retinal surface and cataract treatment precisely entails lens removal, current cataract surgery combines lens removal and inserting a new artificial lens into the eye. Before the cataract operation, measurements for this lens's size, shape, and power will be acquired to prepare the clear lens for implantation during surgery.

Cataract surgery usually entails implanting a mono-focal intraocular lens with a fixed focus at a specified distance. The focus is at a distance, and a reading glass is necessary to view up close. Multifocal intraocular lenses are also common. There is typically no damage in waiting for a considerably longer interval between the two eye procedures.

Cataracts can worsen more quickly in persons with specific illnesses, such as diabetes, high blood pressure, or obesity. Surgery is the only adequate way to remove a cataract, and you can make simple modifications to control cataracts, such as:

  • Increase the brightness of your lights at home or work.
  • Wear anti-reflective sunglasses.
  • Use magnifying glasses for reading and other tasks.

People suffering from early cataracts will discover that adjusting their glasses, using sunglasses to reduce glare, and having improved reading lighting will considerably ease their symptoms. Magnifying glasses may also be useful for close work and fine print reading. Cataract surgery is extremely safe and effective, with most patients experiencing improved vision.

During Cataract Surgery

Cataract surgery includes removing and replacing the clouded lens with a clean prosthetic lens. The artificial lens, an intraocular lens, replaces your natural lens. Once the cataract is removed, eyesight can be restored using eyeglasses or contact lenses. Under local anaesthesia, cataract surgery is often done as an outpatient operation. A small amount of sedation is given before the procedure starts, typically lasting under a half-hour.

Even while cataract extraction is a very safe surgical cataract treatment because of contemporary methods, problems can arise. These include bleeding, infections, retinal detachment, displacement of the lens, and the loss of a part of the cataract into the eye. Fortunately, all of these issues are manageable, and healing often takes a few weeks.

Modern cataract surgery involves keeping a portion of the lens capsule inside the eye to support the intraocular lens. Later on, this capsule may fog up, making a laser usage to open it. A YAG laser capsulotomy is the name of this outpatient procedure, and it is painless.

Consult your cataract doctor if you have visual differences like double vision or flashes of light. Most people do not require immediate surgery. Waiting for surgery normally does not hurt your eyes or make subsequent surgery more difficult. Mind these tips:

  • Inform your doctor if cataracts are interfering with your daily activities.
  • Check in with your cataract doctor regularly.
  • Inquire with your doctor about the advantages and disadvantages of cataract surgery.
  • Ask family members to have their eyes tested for cataracts if they run into the family.


Most doctors wait until cataracts impair a person's vision before recommending cataract surgery. However, by seeing an eye doctor, you can learn what is cataracts and more about your eye's state. You almost certainly know someone who has undergone a cataract operation and can be a resource, and speak with them and inquire about their experiences. However, feel free to arrange surgery.
