A successful LASIK procedure depends heavily on meticulous preparation, and a prescribed regimen of eye drops plays a crucial role. Following your surgeon's specific instructions for when and how to use these drops is paramount for minimizing complications and ensuring an optimal outcome. Here, we break down the different categories of eye drops commonly used in the pre-operative phase of LASIK.
The Purpose of Pre-LASIK Eye Drops
Eye drops are used before LASIK for several key reasons, all aimed at creating the best possible conditions for the surgery and subsequent healing.
- To prevent infection: Even though LASIK is a sterile procedure, the eyes and surrounding eyelids naturally host bacteria. To reduce the risk of post-operative infection, surgeons prescribe a course of prophylactic antibiotic eye drops. This significantly lowers the bacterial load on the ocular surface.
- To control inflammation: Some anti-inflammatory or steroid drops may be used to calm any existing inflammation on the eye's surface. This helps ensure the cornea is in a stable, healthy state for the laser treatment. These are often continued after the procedure to aid in the healing process.
- To optimize the tear film: A healthy, stable tear film is essential for accurate measurements during the pre-operative evaluation and for a smooth recovery. Dry eye can compromise both the procedure and healing. Lubricating, or 'artificial tear,' drops are frequently used in the weeks leading up to surgery to ensure the eyes are well-hydrated and the surface is in prime condition.
- To numb the eye: On the day of the procedure, anesthetic eye drops are administered by the surgical team to ensure the patient feels no pain or discomfort during the surgery itself.
Common Types of Eye Drops Used Before LASIK
While the exact regimen can vary by clinic and patient, most pre-operative LASIK plans include these types of drops:
Antibiotic Drops
These are the primary drops used in the days immediately preceding the surgery to prevent bacterial infection. They are typically started one to two days before the procedure and continued for some time afterward. Common examples include:
- Vigamox (Moxifloxacin): A broad-spectrum fluoroquinolone antibiotic used to kill bacteria and prevent infection.
- Zymar (Gatifloxacin): Another fluoroquinolone antibiotic with a similar purpose. Some clinics may provide this or a generic version.
- Polytrim (Trimethoprim/Polymyxin B): An antibiotic combination sometimes prescribed for pre-operative use.
Anti-inflammatory Drops
These drops work to reduce swelling and inflammation, often prescribed alongside antibiotics. A common example is:
- Prednisolone (Pred Forte): A steroid drop that can be used pre-operatively and post-operatively to manage inflammation.
Lubricating Drops (Artificial Tears)
Many patients are instructed to begin using preservative-free artificial tears weeks in advance of their surgery, especially if they have a history of dry eye. Examples include:
- Systane: A popular brand of artificial tears.
- Refresh: Another widely recommended over-the-counter lubricating drop.
- Oasis Tears: A preservative-free option often suggested by ophthalmologists.
Pre-LASIK Eye Drop Comparison
| Eye Drop Type | Purpose | When to Use | Common Examples | Instructions |
|---|---|---|---|---|
| Antibiotic | Prevent bacterial infection | 1-2 days before surgery | Vigamox, Zymar, Polytrim | Follow surgeon's directions |
| Anti-inflammatory | Reduce inflammation | Varies, often with antibiotics | Prednisolone, Durezol | As directed by surgeon |
| Lubricating | Maintain tear film, prevent dryness | Weeks before surgery | Systane, Refresh, Oasis | As needed or directed |
| Anesthetic | Numb the eye | Day of surgery (in clinic) | Proparacaine, Tetracaine | Administered by surgical staff |
Crucial Considerations for Your Eye Drop Regimen
Beyond just using the prescribed drops, there are other important medication-related instructions to follow for a successful LASIK experience:
- Discuss all medications: Always inform your surgeon about all prescription and over-the-counter medications you are taking. Some, like certain antihistamines and decongestants, can cause dry eyes and may need to be stopped before surgery.
- Pause certain drops: Some medicated eye drops, especially those for allergies, must be discontinued on the day of surgery. Your surgeon will provide specific timing instructions.
- Stop contacts well in advance: Contact lenses can reshape the cornea. You will be instructed to stop wearing them for a specific period before your pre-operative evaluation and surgery to ensure accurate measurements.
- Follow the schedule meticulously: Your surgeon's office will provide a detailed, easy-to-follow schedule for using your drops. Adhering to this timing is critical for ensuring the medications are fully effective.
The Day of Surgery
On the day of your LASIK procedure, you will be given anesthetic drops in the clinic to numb the eye surface. Additionally, you should bring your prescribed antibiotic and anti-inflammatory drops with you, as you will likely start using them shortly after the procedure. You may also be given an oral sedative to help you relax.
Conclusion
The careful use of pre-operative eye drops is a cornerstone of safe and effective LASIK surgery. The regimen typically includes a combination of antibiotic drops to prevent infection and lubricating drops to prepare the eye's surface. Your surgeon's instructions are the final authority on which specific eye drops are used before LASIK and how to use them. By following this protocol, you can help ensure a smooth procedure and an optimal recovery, leading to the best possible visual outcome. Always consult your ophthalmologist to confirm your individual pre-operative care plan.
