Choose Sight Without Glasses: The Benefits of Cataract Surgery

Cataract surgery is one of the most commonly performed and successful medical procedures worldwide, with over 26 million operations each year. This quick, outpatient procedure, typically lasting just 15 to 30 minutes, has the power to dramatically improve your quality of life by restoring clear vision.

Opting for cataract surgery presents a unique opportunity to enhance your vision. The choice between basic cataract surgery and refractive cataract surgery often hinges on whether you want to rely on glasses afterward. Basic cataract surgery is effective, but if you prefer to live free from glasses, refractive cataract surgery with multi-focal lenses might be the right choice. These advanced lenses can provide sharp, clear vision at multiple distances, reducing or even eliminating your dependence on glasses.

When considering cataract surgery, keep the following in mind:

1. Freedom from Glasses: Multi-focal lenses offer the convenience of seeing clearly at various distances without the need for glasses. If you don’t mind wearing glasses basic cataract should meet your needs.

2. Reduced Fall Risk: For individuals over 65, wearing bifocal or multi-focal glasses increases the risk of falls. Cataract surgery with multi-focal lenses can mitigate this risk, potentially preventing 40% of falls linked to bifocal or multifocal glasses.

3. Cost Considerations: While multi-focal lenses involve an out-of-pocket expense, they can save you the ongoing cost of replacing glasses. Remember, most medical insurance plans only cover mono-focal lenses.

4. Time Savings: If you spend just 10 minutes a day searching for or cleaning your glasses, refractive cataract surgery could save you up to 60 hours a year—time you can use for more enjoyable activities.

Understanding Cataracts: A Clear Explanation

Before making decisions about cataract surgery, it’s important to understand the basics.

What is a Cataract?

The lens inside your eye, clear and flexible at birth, gradually loses clarity and flexibility over time. A cataract is a clouding of this lens, much like a smudge on a windowpane, dimming and blurring your vision.

Why Do Cataracts Develop?

Cataracts are a natural part of aging, usually starting around age 40. Over time, proteins in the lens break down and clump together, causing the lens to become cloudy. Symptoms often become noticeable after age 60, though the timing can vary. While cataracts are inevitable, modern medicine ensures they need not hinder your vision permanently.

Deciding on the Right Time for Cataract Surgery

The journey to cataract surgery is a highly personalized one, and it doesn’t always lead to immediate surgery after diagnosis. This important decision is made in close consultation with your eye care specialist. If your cataract symptoms are mild and don’t significantly impact your daily activities, there may be no immediate need for surgery. The key is to time the surgery to achieve the best possible outcome for your vision.

While advancements in technology have come a long way, it’s important to understand that current lens implants can’t fully replicate the functionality of a young, healthy natural lens. Therefore, the optimal timing for cataract surgery is generally when it can offer a substantial improvement in your vision compared to your current experience.

Factors Influencing the Timing of Surgery:

How much your reduced vision impacts daily tasks.
The degree of vision improvement possible with glasses.
If you prefer a life less dependent on glasses, multi-focal lenses can offer superior vision, allowing for earlier intervention even with less advanced cataracts.

Understanding the Risk Factors for Cataract Development:

Genetics: A family history of early cataract onset.
Health Conditions: Diabetes and other health issues can increase the risk of cataracts.
Sun Exposure: Prolonged exposure to UV rays without proper eye protection.
Eye Trauma: Previous eye injuries can accelerate cataract development.

Identifying Cataracts: Signs to Watch For

Cataracts can develop slowly, often going unnoticed until they significantly affect vision. Watch for the following signs:

Double vision
Blurry or hazy vision
Increased need for light especially to read.
Difficulty with night vision
Dull or yellowed colours
Light sensitivity

If you notice any of these symptoms, consult with an optometrist or ophthalmologist for a definitive diagnosis and to discuss your options.

Cataract Surgery: Precision, Comfort & Clarity

Cataract surgery is one of the most precise and successful procedures in modern medicine, with a success rate exceeding 98%. Thanks to technological advancements, most complications can be effectively managed if they arise.

A Look at the Procedure Performed under a high-powered microscope, cataract surgery has been refined with technologies like computer-assisted guidance, which overlays crucial data onto the surgeon’s view. The procedure typically involves numbing the eye with local anaesthetic drops, making small self-sealing incisions at the edge of the cornea, and using ultrasound to break up the cloudy lens. The lens is then removed and replaced with an intraocular lens (IOL), restoring the eye’s focusing ability. This procedure is performed under sedation in a theatre setting, and you’ll be able to go home the same day. Typically, each eye is operated on during separate hospital visits.

Post-Surgery Vision Recovery Healing and full focus adjustment can take 6 to 8 weeks. Mono-focal lenses offer clear vision at one distance, while multi-focal lenses provide a broader range of clear vision, reducing or eliminating the need for glasses.

Choosing the Right Intra-Ocular Lens: A Team Effort

Selecting the right lens is a collaborative process between you and your ophthalmologist. Your surgeon will consider your daily activities, career demands, hobbies, and preferences regarding glasses.

Basic Cataract Surgery and Glasses

If you’re comfortable wearing glasses post-surgery, basic cataract surgery is a good option. Most medical aids cover the cost of mono-focal lenses, which provide clear vision at one distance, usually for distance vision, requiring glasses for near tasks.

Refractive Cataract Surgery

For those leading an active lifestyle or who prefer to live without the inconvenience of glasses, refractive cataract surgery could be the perfect solution.

With Extended Depth of Field (EDOF) lenses, you can enjoy good distance vision and reduced dependence on glasses for intermediate tasks like computer work. However, you may still need reading glasses for close-up activities. Another option is blended vision, where each eye is focused at slightly different distances, enhancing overall visual range. Multi-focal lenses offer a high likelihood—around 90%—of reducing or even eliminating the need for glasses, though some people may still prefer glasses for extended reading sessions.

Premium lenses are designed to significantly improve your quality of life but do come with an additional co-payment. In the pursuit of optimal vision, your surgeon will address not just the cataract but also any astigmatism, fine-tuning your vision to achieve the best possible outcome. While the chances of needing further adjustments are low, many surgeons offer complimentary laser vision correction for the small percentage of patients who might require it after surgery.

It’s important to remember that while modern lens technology strives to replicate the clarity of a young, natural lens, achieving perfection is a challenge. However, with the latest advancements, we can certainly aim for excellence.

How Do Multi-Focal Lenses Work?

Multi-focal lenses have concentric rings with different powers, allowing for simultaneous focus at various distances. Unlike multi-focal glasses, which require you to look through specific zones, multi-focal lenses in your eye let your brain automatically select the correct focus for the task.

How to Choose a Lens?

Your surgeon will help you choose the best lens based on detailed scans of your eyes and your lifestyle needs. Schedule a consultation with your ophthalmologist or reach out to Sandton Eye Clinic via WhatsApp to book a consultation for a personalized recommendation.

Guidelines for Post-Surgery Care: Ensuring Best Outcomes

Daily Activities: You can usually return to your regular routine within 24 hours after surgery. However, it’s important to avoid strenuous activities and heavy lifting for the first few weeks to ensure proper healing.
Restful Sleep: For the first week after surgery, use the provided eye shield while sleeping to protect your eyes from accidental contact or injury.
Driving: Your ophthalmologist will guide you on when it’s safe to resume driving, depending on your recovery progress and visual acuity.
Eye Drops: Follow your prescribed eye drop regimen carefully to prevent infection and promote healing. If you find it difficult to apply the drops, steady your hand by resting it against your forehead or nose.
Environmental Caution: Shield your eyes from irritants like dust and pollen, and protect them from bright lights by wearing sunglasses when outdoors.
Eye Care: Avoid rubbing your eye. If you need to clean your eye area, use a clean tissue instead of a handkerchief to reduce the risk of infection.
Swimming and Water Activities: Avoid swimming for at least one month post-surgery to prevent exposing your eyes to potential contaminants.
Cosmetics: Wait until your doctor gives the go-ahead, typically about two days after surgery, before resuming the use of makeup.

Air Travel: Flying is safe after cataract surgery. However, since air travel can dry out your eyes, be sure to pack your eye drops in your carry-on luggage.

Watch for Danger Signs: Seek immediate medical attention if you experience persistent eye pain, sudden vision changes, nausea, vomiting, or visual disturbances like flashes of light or an increase in floaters.
