Your Timeline for Success: The Weeks Before Surgery
Preparing for eye surgery is not a last-minute task; it begins well in advance. Your surgeon will provide detailed, specific instructions tailored to your procedure, which must be followed precisely. However, there are general guidelines to keep in mind.
Medication and Supplements
One of the most important pre-op tasks is managing your medication. Your doctor will provide specific directions, but these are some common considerations:
- Blood Thinners: For certain surgeries, you may be instructed to stop taking blood thinners like aspirin, warfarin, or NSAIDs (ibuprofen) several days or even a week before the procedure to reduce the risk of bleeding. Never stop or start any medication without your doctor's explicit approval.
- Other Medications: Most regular medications, especially for blood pressure or diabetes, can continue as normal. You will receive instructions on whether to take them with a small sip of water on the morning of your surgery.
- Supplements and Herbs: Many over-the-counter supplements and herbal remedies, such as fish oil, garlic, and ginseng, can have blood-thinning effects. It is crucial to inform your doctor about all supplements you are taking and follow their instructions on when to discontinue them.
Contact Lenses and Makeup
- Discontinue Contact Lenses: If you wear contact lenses, you will likely be instructed to stop wearing them for a specific period before your surgery. For refractive procedures like LASIK, this can be weeks in advance, as contacts alter the shape of your cornea and can affect pre-operative measurements. For other surgeries, it may be just a day or two.
- Avoid All Makeup: On the day of your surgery, you must arrive with a completely clean face. This means no makeup, lotions, or creams. Makeup particles, especially mascara and eyeliner, can introduce bacteria into the surgical area, increasing the risk of infection.
The Final 24-48 Hours: The Home Stretch
As your surgery day approaches, your focus should shift to specific, time-sensitive tasks.
Fasting and Hydration
For many eye surgeries involving sedation or general anesthesia, you will be instructed not to eat or drink anything after midnight the night before your procedure. The time and duration of fasting are critical to prevent complications related to anesthesia.
- Strict Adherence: Follow the fasting instructions to the letter. A nurse from the surgical center will likely call you beforehand to confirm these details. Ignoring these rules can lead to your surgery being postponed or canceled for your safety.
- Brushing Teeth: You can and should brush your teeth on the morning of surgery, but be careful not to swallow any water.
Arranging Transportation and Care
Sedatives and anesthesia will make it unsafe for you to drive or operate machinery for at least 24 hours post-surgery. You must arrange for a responsible adult to drive you home and, ideally, stay with you for the first 24 hours to monitor your recovery.
Comparison of Pre-Op Requirements
Different eye surgeries have varied preparation needs. The table below highlights some key differences between common procedures.
| Requirement | Cataract Surgery | LASIK/Refractive Surgery |
|---|---|---|
| Fasting | Typically required from midnight before surgery. | Usually not required, but confirm with your doctor. |
| Contact Lenses | Discontinue use, often for days or weeks, to allow accurate lens measurements. | Stop wearing lenses weeks before to stabilize the corneal shape. |
| Medication | Adjustments for blood thinners are often necessary. | Typically fewer medication adjustments needed, but discuss with surgeon. |
| Anesthesia | Often involves local anesthetic and sedation. | Usually involves only topical anesthetic eye drops. |
| Driver Required? | Yes, due to sedation. | Yes, due to potential blurry vision. |
Surgery Day: Final Touches
Dressing for Comfort and Safety
Wear loose, comfortable clothing that is easy to put on and take off. A button-up shirt or a top with a wide neck is ideal to avoid pulling clothing over your face and potentially touching your eye. Leave all jewelry, watches, and other valuables at home.
The Final Confirmation
When you arrive at the surgical center, you will be asked to confirm your identity, the procedure, and the eye to be operated on. This is a standard safety measure.
Understanding the Process
Your surgical team will walk you through the process, answer any last-minute questions, and administer any necessary pre-operative eye drops. This is a final opportunity to voice any concerns.

Conclusion
Following preoperative instructions is more than a formality; it is a critical component of a safe and successful eye surgery. By proactively managing your medications, adjusting your lifestyle, and preparing logistically for the day, you play an active and essential role in your own care. Always rely on the specific guidance provided by your ophthalmologist and surgical team, as they are the ultimate authority on your individual procedure and needs.
