How Do You Know If You Have a Cataract? Know What You Should Do

November 30, 2021/0 Comments/in Cataract Surgery /by armadaleeye

Tens of thousands of people around the world are treated with cataract surgery every day. A cataract is a haze or loss of transparency of the crystalline lens inside the eyeball. This results in less light being able to make it through to your retina, causing the image to become degraded and unclear. However, blurry vision is only one of the symptoms of a cataract, and in some cases, not even the first noticeable sign. So, how do you know if you have a cataract and what should you do if you suspect you have one?

How Do You Know if You Have a Cataract?: Symptoms to Look Out For

Fortunately, cataracts are considered benign, typically a normal and expected part of ageing. So if it takes a while to get into an eye care professional for diagnosis, or if you have to wait for cataract surgery, it’s unlikely to cause any harm.

However, as visually significant cataracts are treatable through cataract surgery, it can help to recognise that your symptoms are caused by a cataract. These are some common symptoms of a cataract.

Unclear vision. At some point, you may realise your sight isn’t as sharp as it once was. However, age-related cataracts tend to progress very slowly, making it difficult to discern such minute changes to your vision over an extended period of time. Some people also don’t identify their vision as blurry or unclear at all. Instead, they may describe their sight as foggy, cloudy, hazy, or like constantly looking through a dirty window or smudged glasses.
Altered colour vision. A specific type of age-related cataract known as nuclear sclerosis causes a browning/yellowing of the crystalline lens. This results in certain wavelengths of light being filtered out, which changes your colour perception. Similar to the deterioration of your visual clarity, not everyone will notice this change as it happens very slowly and can be difficult to discern.
Increased glare sensitivity. The opacities of a cataract can cause light to scatter as it enters the eye, which we perceive as glare. You may find that you no longer feel comfortable driving at night as oncoming headlights or street lamps feel too bright. During the day you may feel more dependent on your sunglasses whenever you go outdoors, or perhaps you feel the illumination from your electronic devices is getting uncomfortable.
Reduced contrast sensitivity. Contrast sensitivity refers to our ability to discern detail against a background; for example, words against a page. As a cataract develops and impacts your contrast sensitivity, you may find tasks like reading coloured text against a coloured background becoming more difficult. People with cataracts may also feel uncomfortable driving in low contrast conditions, such as dusk or dawn, or heavy rain.
Frequent changes to your contact lens or spectacle prescription. Although a prescription may change naturally over the course of time, a developing cataract has the potential to shift your eye’s power more rapidly than considered typical. Depending on the type of cataract, your prescription may become either more long-sighted (hyperopic) or short-sighted (myopic), or may even alter your astigmatism.

A cataract is never associated with pain or redness of the eye, nor with a sudden loss of vision. Some types of cataracts may develop more rapidly than others, but they are never responsible for waking up with abrupt vision loss. If you experience pain, redness, or sudden vision loss, even in conjunction with the previously mentioned symptoms of a cataract, you should visit your eye care professional or your local hospital emergency department immediately.

How Do You Know if You Have Eye Cataract?: Diagnosis with an Eyecare Medical Professional

The most definitive way of answering “how do you know if you have a cataract?” is to simply attend for an eye test with your optometrist or ophthalmologist.

While a general practitioner is likely to suspect you have a cataract based on your reported symptoms, they do not typically have access to the necessary equipment to diagnose a cataract.

At the eye care clinic, the optometrist or ophthalmologist will ask you to read letters on a chart to determine your visual acuity. If your contrast sensitivity needs to be tested, they may also use a chart with letters of increasing faintness. The clinician will have a look at the cataract directly using a slit lamp, which is a piece of equipment with a microscope and light assembly.

It’s unnecessary to undergo cataract surgery for cataracts that are early or not considered visually significant. Instead, you’ll be monitored at regular intervals to follow your cataracts as they progress. Once it’s determined that your cataracts are causing you problems, you will be offered cataract surgery.

Cataract Surgery: Treatment to Improve Eye Health

Cataract surgery is typically a quick, uncomplicated day procedure. In Australia, you have the choice of going through the public system or the private system. While the private system offers you more options, such as the type of lens implant, which surgeon performs your operation, and has shorter waiting times, you may incur significant out-of-pocket costs, especially if you don’t have private health insurance. Prior to seeing an eye specialist, you may want to discuss your options for surgery with your local optometrist.

Cataract Surgery Aftercare – Tips on Optimising the Recovery

November 15, 2021/0 Comments/in Cataract Surgery /by armadaleeye

Although cataract surgery is considered a safe and effective procedure, all medical operations carry some degree of risk of a complication or adverse event. These incidents may occur during the operation itself or during the postoperative period.

While some things may be out of the control of both you and your eye surgeon, there are certain steps you can take to reduce your risk of a problem arising during your cataract surgery recovery period. Adhering to best practice guidelines for cataract surgery aftercare may also help to shorten your healing time, getting you back to doing the things you love sooner.

A Brief Explanation of Cataracts and Cataract Surgery

Cataracts are an opacity that forms in the crystalline lens of the eyeball. Increasing age tends to be responsible for the vast majority of cataract cases. As the cataract progresses, you will find your vision gradually becoming less distinct, and even your colour vision may become altered. Among other situations, people with cataracts may complain of difficulties with seeing fine detail, reading in low light, or driving at night.

In the early days of a mild cataract, you may find your vision can be sufficiently improved through changing your spectacle or contact lens prescription, or by increasing your ambient or task lighting. However, the only definitive treatment for a visually significant cataract is through cataract surgery.

During the cataract surgery procedure, the ophthalmologist will remove the cataract through a small incision in your cornea. This is a day procedure performed under topical or local anaesthesia. Most uncomplicated cataract surgeries take as little as 15 to 20 minutes. Once the cataract has been extracted, an artificial lens implant is then inserted in its place. This implant, known as an intraocular lens, is typically calculated to correct your eye’s prescription. This means many people are able to see clearly spectacle-free after their cataract operation.

After your cataract surgery, aftercare guidelines will be provided by your ophthalmologist. In order to optimise your cataract surgery recovery, it’s important to follow these instructions as best as you can.

What to Expect During Cataract Surgery Recovery?

Understanding what is and isn’t expected during your post-operative healing period can help you to act more quickly if something seems amiss.

As a general rule, if anything doesn’t seem quite right with your eye or vision, it’s a good idea to get in touch with your ophthalmologist. They may be able to advise you over the phone as to whether your concerns are something that needs to be attended to immediately, or whether it’s part of the normal course of your cataract surgery recovery.

Immediately after your operation, your vision may be already reasonably sharp, or at least much clearer than when the cataract was still present. Because the intraocular lens implant will be in place, you’ll find your prescription glasses and contacts are no longer the correct scripts.

However, don’t expect your vision to be crystal-clear straight after the operation. As your eye heals and the lens implant settles in its membrane, your vision may continue to shift and improve. A typical timeframe for your vision to settle completely is around 4 to 6 weeks.

Your eye may feel a little gritty for a week or so after the surgery and may look slightly red or puffy. Some people will experience dryness of the eyes that can persist for weeks or months.

At no point should the following be dismissed as normal during your recovery from cataract surgery:

Increasing redness of the eye
Decreasing vision
Flashing lights or floating spots in the vision
Pus or mucous discharge from the eye
Sudden loss or black/greying out of any part of your vision
Increasing pain in the eye

If you experience any of these symptoms, contact your ophthalmologist or optometrist immediately, or visit the emergency department of your local hospital.

Cataract Surgery Aftercare Guidelines

Your ophthalmologist may provide you with slightly different cataract surgery aftercare instructions depending on your specific circumstances. However, these are a general rule of thumb.

Keep the eye protected. As your eye is still healing after cataract surgery, it’s important to protect it from any accidental bumps, pokes, or debris. Wear your provided eye shield as instructed. This may include for the first 24 hours and then overnight every night for the week following your cataract operation. Take a break from any activities that put your eye at risk, such as contact sports or rough play with your children.
Keep the eye clean. In addition to taking care not to get dirt or dust in your eye, try to avoid any other chemicals or substances coming into contact with your eye as it’s healing. This includes cosmetics, moisturisers, soaps, shampoos, and cleansers. You’ll also want to steer clear of pools, the ocean, spas, and saunas as these are a source of a dangerous infection called acanthamoeba keratitis.
Use your prescribed eye drops. Your ophthalmologist will provide you with a script for an antibiotic and one or two anti-inflammatory drops. Use these for the full course as directed; ceasing your medications early will put you at risk of rebound inflammation or an opportunistic eye infection.

If any instructions are unclear to you after your cataract surgery, you may want to discuss them with your ophthalmologist or local optometrist.
