Can You Leave Contacts In for a Colonoscopy?
The definitive answer is generally no. It’s strongly recommended to remove your contact lenses before undergoing a colonoscopy to minimize the risk of complications related to sedation and potential disruptions during the procedure.
The Importance of Colonoscopies
Colonoscopies are a crucial screening tool for detecting and preventing colorectal cancer. This procedure involves inserting a long, flexible tube with a camera attached (a colonoscope) into the rectum and colon to visualize the lining. Early detection allows for the removal of precancerous polyps, significantly reducing the risk of developing cancer. Regular colonoscopies are often recommended for individuals starting at age 45, or earlier for those with a family history of colorectal cancer or other risk factors.
Why Contact Lenses and Sedation Don’t Mix
During a colonoscopy, patients typically receive sedation to ensure comfort and relaxation throughout the procedure. This sedation can affect various bodily functions, including:
- Decreased blinking: Reduced blinking can lead to dry eyes and discomfort, especially with contact lenses in place.
- Reduced tear production: Sedation can inhibit tear production, further exacerbating dry eye symptoms and potentially damaging the cornea.
- Cognitive impairment: Difficulty communicating discomfort or issues related to contact lenses after sedation.
Leaving contact lenses in under these conditions can lead to corneal abrasions, infections, and general discomfort. In rare cases, serious eye problems can occur.
Preparing for Your Colonoscopy: A Step-by-Step Guide
Proper preparation is vital for a successful colonoscopy. Here’s a checklist to ensure you’re ready:
- Consult your doctor: Discuss your medical history, including any allergies or medications you’re taking. Specifically, mention that can you leave contacts in for a colonoscopy, and follow their recommendation.
- Follow the bowel preparation instructions: This involves consuming a clear liquid diet and taking a laxative to cleanse the colon. This part is essential for clear visualization during the procedure.
- Arrange transportation: Due to the sedation, you’ll need someone to drive you home.
- Remove contact lenses: Switch to glasses or wear them without contacts on the day of the procedure.
- Inform the medical staff: Remind the nurses and doctors that you are not wearing contact lenses.
Common Mistakes to Avoid
- Ignoring pre-procedure instructions: Not following the bowel preparation guidelines can lead to an incomplete procedure, requiring a repeat colonoscopy.
- Forgetting to arrange transportation: It’s unsafe to drive yourself home after receiving sedation.
- Consuming prohibited foods or liquids: This can interfere with the bowel preparation and visualization.
- Failure to remove contact lenses: As discussed, this poses a risk to your eye health.
Contact Lens Options
If you routinely wear contact lenses, consider these alternatives:
| Option | Pros | Cons |
|---|---|---|
| Glasses | Comfortable, no risk of corneal damage | May not provide the same level of vision correction as contacts |
| Daily disposables | Convenient, low risk of infection (when new pair is used after procedure) | Can be more expensive than reusable lenses |
| Reusable lenses (cleaned) | Cost-effective | Requires diligent cleaning to prevent infection |
Frequently Asked Questions (FAQs)
Can I wear my glasses during the colonoscopy?
Yes, you can and should wear your glasses to the procedure. Wearing your glasses will allow you to see clearly before and after the procedure. If you typically wear contacts, eyeglasses are the ideal alternative for the day of your colonoscopy.
What if I forget to remove my contact lenses before the colonoscopy?
Inform the medical staff immediately. They will assist you in removing the lenses before administering any sedation. Never proceed with sedation while wearing contact lenses without informing them.
Is there any situation where I can keep my contact lenses in during a colonoscopy?
While it’s not recommended, there might be rare circumstances where your doctor might consider it, such as if you have a medical condition that makes removing them extremely difficult. However, you must discuss this with your physician beforehand.
What are the risks of wearing contact lenses during sedation?
The primary risks include corneal abrasion, dry eye, infection, and potential damage to the cornea due to decreased blinking and tear production.
Can I wear my contact lenses immediately after the colonoscopy?
It is generally safe to reinsert your contact lenses after the procedure once you are fully awake and alert and your eyes feel normal. If you experience any redness, irritation, or discomfort, wait and consult with your eye doctor.
What if I have extended-wear contact lenses?
Even with extended-wear lenses, it’s still strongly advised to remove them before the colonoscopy. The risks associated with sedation apply regardless of the type of lenses you wear.
Does the type of sedation used during a colonoscopy affect whether I can wear contacts?
Regardless of the type of sedation (light, moderate, or deep), the impact on tear production and blinking remains a concern. The recommendation to remove contact lenses applies to all levels of sedation.
Will the hospital provide contact lens solution and a case?
While some hospitals may have these available, it’s best practice to bring your own contact lens solution and a clean case to store your lenses. This ensures you have what you need and minimizes the risk of contamination.
I had LASIK surgery. Does this change whether I can leave my contacts in for a colonoscopy?
Even with LASIK surgery, you should still remove your contact lenses before the procedure. LASIK does not eliminate the risk of dry eye or corneal abrasion during sedation. The recommendation can you leave contacts in for a colonoscopy remains the same: no.
What if I wear scleral lenses?
Scleral lenses are larger and cover more of the eye surface. This increases the risk of complications during sedation. Remove them before the colonoscopy.
Are there any alternatives to contacts or glasses that I can use?
Refractive surgery is an alternative to both contacts and glasses, but it’s a permanent solution that requires careful consideration and consultation with an ophthalmologist. It wouldn’t be practical as a short term solution for your upcoming colonoscopy. The simple answer remains: you’ll want to wear your glasses for the procedure instead.
What should I do if I experience eye pain after the colonoscopy?
If you experience any eye pain, redness, or vision changes after the colonoscopy, contact your eye doctor immediately. You may have a corneal abrasion or other eye problem that requires treatment.
