Why Do You Have To Be Awake For Eye Surgery? A Closer Look At Patient Engagement

November 20, 2024/0 Comments/in Laser Eye Surgery /by Armadale Eye Clinic Team

Eye surgery, particularly laser eye surgery, has become popular for individuals seeking to correct vision problems and achieve clearer vision. One common question patients have is: Why do you have to be awake for eye surgery?

This article delves into the reasons behind this practice, types of laser eye surgeries, benefits, and what to expect during the procedure. Understanding these aspects can help individuals feel more confident and excited about their journey towards a better vision.

Why Do You Have To Be Awake For Eye Surgery?

Staying awake during eye surgery might seem daunting, but there are important reasons why this approach is used. Let’s explore these reasons in more detail.

Enhanced Precision And Quality

One primary reason patients need to stay awake during eye surgery is to ensure enhanced precision and quality.

Procedures like LASIK (Laser-Assisted in Situ Keratomileusis) require the patient’s cooperation to maintain eye position and focus.

Staying awake helps the surgical team monitor eye movements, ensuring the laser targets the correct areas.

Minimising Risks Involved

Being awake during the eye procedure allows patients to provide immediate feedback if they experience discomfort or unusual sensations.

This real-time communication with the eye surgeon helps promptly address any issues, thereby minimising the risks involved.

Avoiding General Anaesthesia

General anaesthesia, which induces sleep, is not typically preferred for eye surgeries like LASIK and cataract surgery.

Instead, local anaesthetics, such as numbing eye drops, are used to ensure the patient remains comfortable without the need for deep sedation.

Types Of Laser Surgery

Various types of laser eye surgeries are available, each suited to different vision correction needs. Here are some of the most common types.

LASIK Eye Surgery

LASIK surgery is the most well-known laser eye surgery for correcting refractive issues such as myopia, hyperopia, and astigmatism.

The LASIK procedure involves making a thin flap in the cornea, reshaping the underlying tissue with a laser, and then repositioning the flap. The entire process usually takes only a few minutes per eye.

PRK (Photorefractive Keratectomy)

PRK is another type of laser eye surgeries that do not incorporate creating a corneal flap. Instead, the cornea’s outer layer is removed, and the underlying tissue is reshaped using an advanced laser beam.

This procedure is often recommended for patients with thinner corneas.

SMILE® (Small Incision Lenticule Extraction)

SMILE® is a minimally invasive laser eye procedure that entails creating a small incision in the cornea to remove a lenticule (a small piece of corneal tissue). This procedure is known for its quick recovery time and minimal discomfort.

Benefits Of Laser Eye Surgery

Laser eye surgery offers numerous benefits, making it an attractive option for many patients. Let’s look at some of these advantages.

Quick Recovery And Minimal Discomfort

One of the most significant benefits of laser eye surgery is the quick recovery time. The vast majority experience mild discomfort for a few hours post-surgery and can return to normal activities within a day or two.

Clearer Vision

Laser eye surgery ensures clearer vision, reducing or eliminating the need for corrective lenses like glasses or contact lenses. Many patients report significantly improved vision shortly after the procedure.

Long-Lasting Results

The results of laser eye surgeries are generally long-lasting, providing patients with better vision for many years. This makes it a cost-effective solution in the long term.

What To Expect During Laser Eye Surgery

Understanding what to expect during laser eye surgery can help ease anxieties and ensure patients are well-prepared.

Pre-Procedure Preparations

Before the surgery, patients undergo a comprehensive eye test to determine their eligibility for the procedure. The eye doctor discusses the specific procedure, potential risks, and expected outcomes. It’s essential to follow all pre-surgery instructions provided by the surgeon.

During The Procedure

Patients will receive numbing drops on the day of the surgery to ensure they remain comfortable throughout the process. The surgical team will use tiny tools to keep the eyelids open and ensure the eye stays in the correct position. Mild sedatives may be provided to help patients remain calm.

The Procedure Process

The surgical procedure is relatively quick, often taking only a few minutes per eye. Patients must focus on a bright light while the laser reshapes the cornea. Due to the numbing eye drops, most patients do not feel much pain despite being awake.

Post-Procedure Care

After the surgery, patients may experience dry eyes and mild discomfort for several hours. It’s crucial to follow the post-surgery care instructions the eye surgeon provides, which may include using prescribed eye drops and avoiding strenuous activities.

Frequently Asked Questions

Is there any pain after laser refractive surgery?

Yes, some patients may feel slight pressure after laser eye surgery, but this is generally well-tolerated. Your eye specialist will tell you exactly what to do after the surgery.

How long does the recovery take?

The recovery time for laser eye surgery can be quick. Patients may resume normal activities within a day or two with minimal discomfort. Follow-up visits may be essential to ensure proper healing and the best possible outcomes.

Is it possible to drive immediately after the surgery?

It is advisable to arrange for someone to drive patients home after the surgery, as their vision may be blurry, and they may experience light sensitivity. Patients may drive within a few days, depending on their recovery progress.

What are the risks involved?

Potential risks involved include dry eyes, glare, or under- or over-correction. Patients are encouraged to discuss these risks and their medical history with their eye doctor beforehand to help them make an informed decision.

Final Thoughts: Why Staying Awake Enhances Your Eye Surgery Experience

Staying awake during eye surgery, such as LASIK, is essential for improving the procedure’s accuracy and quality. Using anaesthetic drops makes the patient experience comfortable while allowing the surgical team to achieve the best outcomes.

Understanding the reasons behind staying awake and what to expect during the procedure can help patients feel more confident and excited about their journey towards a better vision.

Laser eye surgeries offer numerous benefits, including quick recovery, clearer vision, and long-lasting results. If you are considering laser eye surgery, consult a qualified eye specialist to identify the best possible approach for your vision needs and enjoy the life-changing benefits of better vision.

Remember to follow all pre- and post-surgery instructions provided by your surgical team and attend the required follow-up appointments to ensure a simple recovery and optimal results.

How Long Does It Take To Go Blind From Cataracts? A Simplified Guide

November 6, 2024/0 Comments/in Cataract Surgery /by Armadale Eye Clinic Team

Cataracts are one of the most common eye conditions affecting people worldwide, particularly as they age. As the eye’s natural lens becomes clouded, vision deteriorates, potentially leading to blindness if left untreated. But how long does it take to go blind from cataracts?

The answer may vary greatly depending on several factors, including the type of cataract, the individual’s overall health, and more.

This simple guide will walk you through cataracts, explain the different types of cataracts, and outline what to expect if you’re considering cataract surgery.

What Are Cataracts?

Cataracts occur when the eye’s lens becomes clouded. If left untreated, they can lead to blurred vision and, eventually, complete vision loss. The lens focuses light onto the retina, allowing clear vision.

Developing cataracts means the lens becomes opaque, causing progressive vision impairment. Cataracts are considered a typical part of ageing, but other factors, such as eye injuries, steroid medications, and underlying medical conditions like diabetes, may contribute to their formation.

How Long Does It Take To Go Blind From Cataracts?

The progression from mild symptoms to total vision loss can take years or even decades, depending on the type of cataract and the individual’s health. However, it may not be every day that you see someone go blind from cataracts, as treatment is typically available long before the condition reaches such a critical stage.

In all, there are several factors that influence how long it takes to go blind from cataracts, such as:

Type Of cataract: Different cataracts progress at different rates.
Age: Age-related cataracts often develop slowly, while paediatric or traumatic cataracts may progress faster.
Health Conditions: Conditions like diabetes or poor nutrition can accelerate cataract growth.
Exposure To Risk Factors: Prolonged exposure to UV light, steroid medications, or smoking can contribute to faster cataract development.

Types Of Cataracts

Understanding the different types of cataracts can give you a better idea of how they develop and how long it may take for vision loss to occur.

Age-Related Cataracts

These are the most common types and typically develop slowly over time. The ageing process causes proteins in the lens to clump together, leading to cloudiness. People with age-related cataracts often don’t experience significant vision problems until their 60s or 70s, although cataracts can start forming in their 40s or 50s.

Congenital Cataracts

Congenital cataracts are present at birth or progress during childhood. Genetic factors, infections during pregnancy, or developmental issues can cause these. Paediatric cataracts may progress quickly and require early intervention to prevent permanent vision loss.

Traumatic Cataracts

As the name suggests, traumatic cataracts develop after an eye injury. Depending on the severity of the trauma, these cataracts can form rapidly. Immediate medical attention is crucial to prevent cataracts from progressing to blindness.

Cortical Cataracts

These develop on the outer edges of the lens and gradually move inward, creating a “spoke-like” appearance. Cortical cataracts can cause significant vision problems, particularly in bright light, and may progress more quickly than other types.

What To Expect Before, During, And After Cataract Surgery

When cataracts begin to significantly affect your quality of life, your eye expert may recommend cataract surgery. This is a common procedure with a high success rate. It entails replacing the clouded lens with an artificial lens.

Cataract treatment aims to restore clear vision and prevent further vision impairment.

Pre-Surgery Preparations

Before cataract surgery, the eye doctor will conduct a detailed eye exam to measure the size and shape of your eye. This ensures that the artificial lens will fit precisely. You may also be advised to stop taking specific medications or tweak your diet in the days leading up to surgery.

The Cataract Surgery Procedure

During the surgery, the eye surgeon will make a small cut in the eye, remove the diseased lens, and replace it with a clear artificial lens. The procedure usually takes about 30 minutes and is performed under local anaesthesia, meaning you’ll be awake but won’t feel much pain.

Recovery After Cataract Surgery

Patients should experience improved vision within a few days of cataract surgery, although it may take several weeks for your vision to fully stabilise. During recovery, you must follow your doctor’s instructions carefully, including using prescribed eye drops and avoiding strenuous activities.

Long-Term Outlook After Cataract Surgery

With successful surgery, most patients regain clear vision and significantly improve their quality of life. In some cases, patients may still need glasses for reading or distance vision, but the overall outcome is typically positive.

Frequently Asked Questions

Can cataracts be reversed without surgery?

No, once a cataract has formed, it cannot be reversed without surgery. However, lifestyle changes such as wearing UV-protective sunglasses, adhering to a healthy diet, and avoiding smoking can slow the progression of cataracts. Cataract surgery remains the only effective treatment to remove cataracts and restore clear vision.

What are the risks of cataract surgery?

Cataract surgery is a simple and common eye procedure. However, like any surgical procedure, there are some risks, including infection, inflammation, swelling, and, in rare cases, retinal detachment. Your eye expert will discuss these risks with you in detail before the procedure, but complications may be minimised when an experienced surgeon performs the surgery.

Can cataracts return after surgery?

Once a cataract has been removed, it cannot grow back. However, some patients may develop a condition known as “posterior capsule opacification” (PCO), which can cause blurry vision similar to cataracts. This is not a recurrence of cataracts and can be easily treated with a quick, straightforward laser procedure to restore clear vision.

Cataracts And Vision Loss: Early Detection Is Key

Cataracts are a common but manageable cause of vision loss. While it can take years or even decades to go blind from cataracts, early detection and timely intervention with cataract surgery can prevent total vision loss and restore clear vision.

By taking proactive steps to protect your eyes and monitor for signs of cataracts, you can maintain your vision and enjoy a high quality of life well into your later years.
