Why Do You Need Eye Drops After LASIK?
As your eyes recover from laser-assisted in situ keratomileusis (LASIK) surgery, it's common to experience temporary dryness accompanied by mild irritation and itchiness.1, 2 According to research, post-LASIK dry eye symptoms usually peaks in the first couple months after surgery.3
Lubricating eye drops, also known as liquid tears, can be applied to the affected eye to ease the negative side effects of the surgery. These eye drops also provide a sanitary option for delivering medication to the eyes.
Since the LASIK scar is prone to infection, eye doctors prescribe antibiotic eyedrops and steroid eye drops to prevent infection and inflammation.4
Timeline For Post-LASIK Eye Drops
Your eye doctor will provide a timeline for using your post-LASIK eye drops. It’s usually several weeks to months after surgery. Over-the-counter eye drops may be used for as long as you feel any dryness.
On average, antibiotic eyedrops are used for 7-10 days. On the other hand, steroid drops such as Prednisolone Acetate are used sparingly over 2 weeks.5
What Will Happen If You Don’t Use Eye-Drops After LASIK?
If you don't use eyedrops to ease your symptoms and prevent mild side effects of the procedure, the following may happen:
- Mild symptoms will become severe. Severe dry eyes can lead to dislodging of the LASIK flap due to constant friction as you blink or rub your eyes.
- The scar may get infected. Without tears or antibiotic eye drops, harmful bacteria will increase in numbers and potentially cause serious infections or blindness.
- Diffuse lamellar keratitis (DLK). This is inflammation under the LASIK flap caused by the accumulation of white blood cells under the flap.
- Prolonged recovery process. Eyedrops enable a smooth healing process. Constant irritation and infections will delay the healing timeline.
- Blindness. Although rare, poor post-op care practices after LASIK can cause serious complications that put your eyesight at risk.6
Experts advise LASIK patients to carry eye drops for a few months after the procedure. If you forget to use your drops, apply them as soon as you remember.
6 Best Types of LASIK Eye Drops
Below are the market's best types of eye drops for LASIK recovery.
1. Best Overall: SYSTANE® ULTRA Lubricant Eye Drops
Systane Ultra Lubricant Eye Drops are clinically proven to offer long-lasting relief from dry eyes and associated symptoms, such as blurriness, excess tearing, and gritty eyes. The active ingredients are polyethylene glycol and Propylene glycol.
The manufacturer, Alcon Laboratories, Inc, markets it as the #1 doctor-recommended brand of artificial tears, offering single-use convenience.
The preservative-free formula provides night protection and is safe to use before and after wearing your contact lenses. However, seek your doctor's advice before wearing contacts following LASIK surgery.

2. Best for Severe Dry Eyes: SYSTANE® Gel Drops
This thick formulation provides lubrication and long-lasting relief from dry eye irritation after LASIK. Once you apply the drops, the formula creates a thick film over your eyeball, acting as a barrier against irritating dry air or debris. This significantly eases severe dry eye symptoms.

The manufacturer claims that the lubricating formula is designed to last longer in the eye and works with every blink to provide long-lasting relief. It also reduces the occurrence of blurring associated with other types of eyedrops.
Blink Tears Eye Drops are available in 0.5 fl oz (15mL) and 1.0 fl oz (30mL) bottles.

What to Look For in Eye Drops
In addition to being preservative-free, good eye drops for dry eyes will have:
- Lubricating agents (most products artificial tears have them)
- Guar gum or Hydroxypropyl-guar (HP-Guar).7 This is an agent that’s helpful if your tears dry/evaporate off quickly.
- Antibacterial agents to prevent infections
What If Dry Eye Symptoms Don’t Improve?
Without enough tears, your eyes will be prone to irritation, inflammation, and possible infection.
If your dry eye does not improve after LASIK surgery, consult your ophthalmologist for professional advice during your follow-up visits. They'll examine your eyes to rule out any underlying conditions and recommend the appropriate treatment.
Other Ways to Prevent Dry Eye After LASIK
Eye drops are not the golden solution to all dry eye problems. Other ways to prevent dry eyes after LASIK include:
- Avoiding smoking or smoky environments
- Avoiding dry areas (dry weather conditions)
- Protecting your eyes from pollen, dust, and other particulate matter in the air
- Wearing eye protection, such as sunglasses or prescription goggles, in appropriate situations
- Using Scleral Contact Lenses to maintain tears within the eye
- Drinking plenty of water (keeps the body and eyes hydrated)
- Changing your diet (e.g., including omega-3 fatty acid-rich foods and supplements)
Following the above prevention measures and proper eye drop use will enhance healing outcomes after LASIK by preventing complications and reducing the recovery timeline.
When to See Your Eye Doctor
Dry eye symptoms after LASIK are only temporary and should ease up with time. However, if you experience persistent and severe dry eyes accompanied by the following, reach out to your eye doctor:
- Little or no relief from prescription eye drops
