Planning for PRK surgery is an exciting step towards clearer vision, and you might be wondering about the practical preparations. One common question many people have is about their contact lenses: “How long to stop wearing contacts before PRK?” It can seem a bit confusing with so many different advice out there. This guide will break down exactly what you need to know, making the process straightforward and reassuring. We’ll cover why this step is so important and what you can expect right here in Dubai.

Understanding PRK and Contact Lens Wear

Photorefractive keratectomy, or PRK, is a highly effective laser eye surgery. It reshapes the cornea to correct refractive errors like myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. Unlike LASIK, PRK involves removing the outermost protective layer of the cornea, known as the epithelium, before the laser reshaping. This layer then regenerates over several days.

Contact lenses, while convenient for daily vision correction, can temporarily alter the shape of your cornea. Even soft contact lenses can cause subtle changes. This is why it’s essential for your eye surgeon to measure your cornea in its natural, unaltered state. Any residual effect from contact lens wear could lead to inaccurate measurements. These inaccuracies might compromise the precision of the laser treatment, potentially affecting your final visual outcome.

In a city like Dubai, known for its cutting-edge technology and advanced medical facilities, ensuring the utmost accuracy in procedures like PRK is paramount. The goal is to achieve the best possible vision for you after surgery. This requires meticulous preparation, and stopping contact lens wear ahead of time is a critical part of that process.

Why You Need to Stop Wearing Contacts Before PRK

The primary reason for discontinuing contact lens wear before PRK is to allow your cornea to return to its natural resting shape. Here’s a more detailed look at why this is so important:

• Accurate Corneal Measurements: During your pre-operative evaluation, your ophthalmologist will perform several diagnostic tests. These include corneal topography and tomography, which map the surface of your eye. Contact lenses can induce “corneal warpage,” a distortion in the cornea’s natural curvature. If these measurements are taken while your cornea is still influenced by contact lenses, they will be inaccurate. This is critical, as these measurements guide the laser to reshape your cornea precisely.
• Preventing Surgical Errors: An incorrect corneal map can lead to the laser being applied to the wrong areas or with the wrong power. This could result in under-correction, over-correction, or even induced astigmatism, all of which would negatively impact your vision post-surgery.
• Ensuring Consistent Results: PRK aims to provide stable, long-term vision correction. Wearing contacts too close to the surgery date can make your vision fluctuate, making it difficult for the surgeon to predict and achieve the desired outcome.
• Healing and Epithelial Integrity: While not the primary reason for stopping lenses, there’s a slight possibility that wearing contacts could influence the healing of the corneal epithelium post-PRK if there are any underlying issues not detected due to lens wear. Allowing the cornea to stabilize helps ensure a smoother healing process.

Think of it like trying to measure a perfectly flat surface after placing an object on it. You need to remove the object to get the true measurement of the surface itself. Similarly, your cornea needs to be free of the artificial shape imposed by contacts for accurate surgical planning.

How Long Is the Recommended Break?

The general consensus and standard recommendation from ophthalmologists, including those practicing in leading Dubai eye clinics, is to stop wearing contact lenses for a specific period before your PRK surgery.

Standard Recommendation: Two Weeks

For most patients, the recommended time to stop wearing contact lenses before PRK is two weeks. This two-week period allows sufficient time for the cornea to fully return to its natural shape and for any subtle warpage induced by lenses to resolve. This timeframe applies to both soft and rigid gas permeable (RGP) lenses, although RGP lenses can sometimes cause more pronounced warpage and may require a longer discontinuation period in some cases.

What About Different Types of Contacts?

The type of contact lenses you wear can influence how long your cornea takes to stabilize. However, the two-week guideline is a safe and effective measure for most situations.

• Soft Contact Lenses: These are the most common type. They are generally more forgiving, but still can affect corneal shape. Two weeks is typically adequate.
• Rigid Gas Permeable (RGP) Lenses: RGP lenses are firmer and sit on the cornea, potentially causing more significant distortion. Some surgeons might suggest a longer break, perhaps three to four weeks, if significant corneal warpage is suspected or if you have a history of issues with RGP lenses.
• Toric Lenses: These lenses correct astigmatism. If you wear toric lenses, stopping wear is crucial to ensure an accurate measurement of your natural astigmatism.
• Multifocal Lenses: Similar to toric lenses, multifocal lenses can also alter the cornea’s refractive properties, necessitating a break before PRK.

It’s crucial to discuss your specific contact lens usage and type with your surgeon. They will provide a personalized recommendation based on your eye health and lens history.

What If I Can’t See Without My Contacts?

This is a valid concern for many individuals, especially those with high prescriptions. If you find it difficult to function without your contacts during the pre-operative period, your ophthalmologist will likely advise you to switch to wearing your prescription eyeglasses full-time during the two-week (or longer) break. This ensures you can see clearly while allowing your corneas to stabilize. Do not try to wear your contacts for brief periods; the goal is complete cessation.

The Pre-Operative Consultation and Screening

Your journey to PRK surgery in Dubai will begin with a thorough pre-operative consultation and examination. This is where the crucial decisions about your contact lens wear are made and communicated to you.

Detailed Eye Examination

During your visit, the eye care team will conduct a comprehensive eye exam. This will include:

• Visual Acuity Test: To measure your current vision.
• Refraction: To determine your exact prescription.
• Slit Lamp Examination: To check the overall health of your eyes, including the cornea, conjunctiva, and eyelids.
• Intraocular Pressure (IOP) Measurement: To check for glaucoma.
• Fundus Examination: To assess the health of your retina and optic nerve.

Corneal Mapping

This is a critical part of your assessment, especially regarding contact lens wear. Advanced imaging technologies are used:

• Corneal Topography: This technology maps the curvature of your cornea, highlighting any irregularities or steep/flat areas.
• Corneal Tomography: This provides a more detailed 3D map of the cornea, including its thickness and structure.

Your ophthalmologist will analyze these maps to understand your unique corneal profile. If they suspect contact lens-induced warpage, they may recommend a longer break or repeat the measurements after a period of wearing glasses.

Surgeon’s Instructions

Your surgeon will provide you with a clear, written list of instructions regarding contact lens wear. They will explicitly state “how long to stop wearing contacts before PRK” based on your individual case. It is imperative to follow these instructions precisely. If you are unsure about any part of the instructions, do not hesitate to ask your doctor or their clinical staff. Clear communication is key to a successful surgical outcome.

What Happens if You Don’t Stop Wearing Contacts in Time?

Ignoring the advice to stop wearing contact lenses before PRK can have several negative consequences. These are risks that the pre-operative measurements are designed to prevent. Dubai’s focus on patient safety and optimal outcomes means your medical team will emphasize adherence to these guidelines.

• Inaccurate Surgical Planning: As discussed, the laser treatment is programmed based on your corneal measurements. If these are skewed by contact lens wear, the laser will be programmed incorrectly
• Suboptimal Vision Results: This inaccuracy can lead to vision that is not as sharp or clear as it could have been. You might still need glasses or contacts, or experience visual disturbances like glare or halos.
• Need for Additional Procedures: In some cases, if the initial PRK results are significantly suboptimal due to pre-operative measurement errors, a retreatment (enhancement) might be considered. However, this is not always possible or advisable, and it incurs further cost and recovery time.
• Compromised Healing: While less common, sometimes residual corneal distortion can indirectly affect how smoothly the epithelium heals.

“The devil is in the details” when it comes to refractive surgery, and adhering to the pre-operative contact lens wear guideline is a crucial detail that ensures the technology performs as intended for your unique eyes.

Pro Tips for the Pre-PRK Contact Lens Break

Navigating the period before your PRK surgery can be made smoother with a few practical tips:

• Mark Your Calendar: Once your surgery date is set, immediately calculate and mark the date you need to stop wearing your contacts. Set reminders on your phone.
• Switch to Glasses Early: Don’t wait until the last minute. Transition to wearing your glasses full-time a few days beforehand. This helps you adjust and ensure you don’t accidentally put in your contacts out of habit.
• Keep Your Glasses Safe: Make sure your eyeglasses are in good repair. If they are old or the prescription is outdated, consider getting an updated pair for comfort during this period.
• Communicate with Your Surgeon: If you have any doubts or feel your eyes are not stabilizing, inform your eye care team immediately. They might suggest additional checks or a slightly extended break.
• Avoid Eye Rubbing: Be extra gentle with your eyes during this period. Rubbing can further irritate or temporarily distort your cornea.

The PRK Procedure and Recovery: What to Expect

Understanding the whole process, including what happens after you stop wearing your contacts, can ease any anxiety. Dubai’s healthcare providers are equipped with advanced technology to ensure your PRK experience is as comfortable and effective as possible.

On the Day of Surgery

You will arrive at the clinic, and your eyes will be prepared. A topical anesthetic will be used to numb your eyes. The surgeon will gently remove the corneal epithelium, often using an alcohol solution or a surgical instrument. Then, the excimer laser is used to painlessly reshape your cornea. A special bandage contact lens is usually placed on the eye to protect the healing surface.

Post-Operative Care and Recovery

Your recovery after PRK is different from LASIK. While there is no flap to heal, the epithelial regrowth takes time, which means vision recovery is slower.

• Pain Management: You may experience discomfort, light sensitivity, and a feeling of having something in your eye for the first few days. Prescription eye drops and oral pain relievers will be provided.
• Bandage Contact Lens: This lens is typically removed by your doctor within 3-7 days after surgery as the epithelium heals.
• Vision Improvement: Your vision will gradually improve over the first few weeks. Initial blurriness is common. Significant improvement is usually noticeable after a week, but it can take 1-3 months for vision to stabilize completely.
• Medication Schedule: You will be prescribed a regimen of antibiotic, steroid, and moisturizing eye drops. Adhering strictly to this schedule is vital for preventing infection and managing inflammation.
• Follow-Up Appointments: Regular follow-up appointments are crucial to monitor your healing and vision. These typically occur at 1 day, 1 week, 1 month, 3 months, and sometimes 6 months post-surgery.

Dubai’s accredited centers offer state-of-the-art care to manage your recovery effectively. Always follow the specific post-operative instructions given by your surgeon meticulously.
