How to Prevent and Treat Dry Eyes After LASIK Surgery
LASIK surgery offers the convenience of clear vision without glasses or contact lenses, but for many patients, a common side effect is dry eye. This condition, while typically temporary, can cause discomfort and may interfere with recovery if left unaddressed.
In this article, we explore the causes of dry eyes after LASIK, how to prevent it, treatment options available, and expert-recommended home remedies to ensure a smoother recovery and better post-operative comfort.
Why Does LASIK Cause Dry Eyes?
LASIK (Laser-Assisted In Situ Keratomileusis) reshapes the cornea to improve vision. During the procedure, a flap is created in the corneal tissue, and some nerves responsible for tear production may be temporarily damaged. This interferes with the eye’s ability to signal dryness, leading to reduced tear production and dry eye symptoms.
Key causes of post-LASIK dry eyes:
- Temporary disruption of corneal nerves
- Reduced blink rate after surgery
- Pre-existing dry eye condition worsened by LASIK
- Inflammation due to surgical trauma
Most cases of LASIK-induced dry eye improve within weeks or a few months, but some may require longer management depending on individual healing rates.
Symptoms of Dry Eyes After LASIK
It’s normal to experience some discomfort after LASIK, but signs of dry eyes may include:
- Burning or stinging sensation
- Grittiness or feeling of sand in the eye
- Redness or irritation
- Blurry or fluctuating vision
- Watery eyes (reflex tearing due to dryness)
- Light sensitivity
How Long Does Dry Eye Last After LASIK?
For most patients, dry eyes subside within 3 to 6 months after surgery. However, the duration can vary based on:
- Age and hormonal changes (especially in postmenopausal women)
- Pre-existing eye conditions
- Environmental factors (like air conditioning or screen exposure)
- Hydration and lifestyle habits
Persistent dry eye beyond 6 months may require further evaluation by an ophthalmologist or cornea specialist.
Preventing Dry Eyes Before and After LASIK
1. Pre-Surgery Evaluation
Reputable LASIK centres conduct a comprehensive dry eye screening before surgery. If you already have mild dry eye symptoms, your surgeon may recommend pre-treatment with artificial tears or medications to stabilise your tear film before LASIK.
2. Use of Preservative-Free Eye Drops
Artificial tears are typically recommended several times a day post-surgery. Choose preservative-free options to reduce irritation.
3. Blink More Often
Consciously blinking, especially during screen time, helps distribute tears and reduce surface dryness.
4. Humidify Your Environment
Use a humidifier in air-conditioned or heated rooms to prevent your eyes from drying out due to environmental factors.
5. Stay Hydrated
Drinking plenty of water helps maintain overall eye hydration and tear production.
Treatment Options for Post-LASIK Dry Eye
1. Artificial Tears
First-line treatment, typically recommended immediately after surgery. Use as often as required—sometimes up to every hour in the early days.
2. Lubricating Eye Gels or Ointments
These thicker solutions provide longer-lasting relief, especially during sleep. Apply at night to maintain moisture while you rest.
3. Anti-Inflammatory Eye Drops
Doctors may prescribe steroid or cyclosporine (Restasis) drops to reduce inflammation and stimulate tear production in moderate to severe cases.
4. Punctal Plugs
These are tiny silicone or collagen plugs inserted into tear ducts to block drainage and keep tears on the eye surface longer. Safe, reversible, and effective in many chronic dry eye cases.
5. Omega-3 Supplements
Studies suggest omega-3 fatty acids (found in fish oil or flaxseed) can improve the quality and consistency of tears. Consult your doctor before starting supplements.
6. Serum Eye Drops
For severe, persistent cases, autologous serum drops (made from your own blood) may be used to promote healing and reduce inflammation.
Home Remedies for Dry Eyes After LASIK
Alongside medical treatment, several natural remedies can help soothe and support your eyes:
- Warm Compress: Improves oil gland function and soothes irritated eyelids
- Castor Oil Eye Drops: May reduce evaporation and inflammation (must be ophthalmologist-approved)
- Frequent Eye Rest: Follow the 20-20-20 rule: Every 20 minutes, look at something 20 feet away for 20 seconds
- Avoid Wind and Direct Airflow: Wear wraparound sunglasses outdoors; avoid ceiling fans and car vents aimed at your face
Foods That Support Eye Moisture
A balanced diet supports ocular health and tear production. Include:
- Fatty fish (salmon, sardines)
- Flaxseeds and chia seeds
- Vitamin A-rich foods (carrots, sweet potatoes)
- Leafy greens like spinach and kale
- Walnuts and almonds
When to See Your Doctor
While mild dryness is expected post-LASIK, seek medical advice if you experience:
- Persistent or worsening symptoms beyond 3–6 months
- Severe pain or vision changes
- Signs of infection (yellow discharge, swelling)
Real-Life Example
Case: Riya, a 32-year-old marketing executive, developed dry eyes a week after LASIK. She followed her surgeon’s advice—using preservative-free drops every two hours, took omega-3 supplements, and avoided air-conditioned spaces. Within two months, her symptoms greatly reduced, and her vision remained clear and sharp.
FAQs on Dry Eyes After LASIK
Is dry eye permanent after LASIK?
In most cases, it is temporary and resolves within a few months. Persistent cases are rare and manageable with medical help.
Can I use over-the-counter drops for LASIK-related dryness?
Yes, but make sure they are preservative-free. Your eye surgeon may recommend specific brands suitable for post-surgery care.
Does LASIK worsen pre-existing dry eye?
Yes, it can. That’s why pre-operative screening is crucial. Patients with severe dry eye may be advised against LASIK.
How soon can I resume screen time after LASIK?
You should limit screen time for the first few days. Gradually increase usage while using lubricating drops and taking regular breaks.
Can drinking more water help with dry eyes?
Yes. Staying hydrated helps maintain tear volume and prevents evaporation-related dryness.
