LASIK Eye Surgery and its Connection to Dry Eyes: Understanding Causes, Potential Issues, and Preventative Measures
LASIK surgery, a popular procedure for correcting vision, can sometimes lead to dry eye symptoms. This article aims to shed light on the common causes, risk factors, and treatment options for dry eye after LASIK.
Causes and Risk Factors
Dry eye after LASIK is often the result of temporary damage to corneal nerves, changes in the eye's shape, or alterations in the amount of mucin on the eye. The common causes and risk factors for this condition include:
- Damage or disruption to corneal nerves during flap creation, which affects tear production and tear film stability.
- Being female, especially post-menopausal women
- Age over 50 years
- High refractive corrections (large prescriptions), which often require deeper corneal reshaping
- Pre-existing dry eye disease (DED) or dry eye symptoms before surgery
- Use of medications that reduce tear production, such as antihistamines or antidepressants
- Corneal factors like thinner residual stromal bed after surgery may contribute indirectly by influencing healing and tear film quality
Symptoms and Treatment
Dry eye symptoms can range from a burning sensation, gritty feeling, fluctuating vision, redness, and discomfort. Patients with chronic dry eye before LASIK are at higher risk of severe symptoms postoperatively and need careful preoperative management to optimize tear film health.
Treatment options for dry eye after LASIK may involve:
- Artificial tears to supplement natural tear production
- Punctal plugs to prevent excessive tear drainage
- Advanced dry eye therapies like autologous serum eye drops, cyclosporine (Restasis), and lifitegrast (Xiidra)
Alternative Surgeries and Preventive Measures
SMILE, an alternative to LASIK, may have a lower risk of dry eye symptoms post-surgery due to its lower involvement of the cornea. If a person cannot manage dry eye symptoms before LASIK surgery, their eye doctor may advise against the surgery. Staying hydrated and using tear supplements can help manage dry eye symptoms.
Long-Term Management
In some cases, dry eye symptoms may persist for months or even over a year. If a person experiences worsening symptoms or if pain and other symptoms remain for many months after LASIK surgery, they should see a doctor. People with chronic dry eye may require ongoing treatment.
Other Risk Factors
Other risk factors for developing dry eye after LASIK include being female, age over 50, certain eye shapes, specific eye conditions (keratoconus, eye infections, glaucoma, cataract), and autoimmune conditions like Sjogren's syndrome and diabetes.
Conclusion
While LASIK surgery offers the potential for improved vision, it's essential to be aware of the potential risks, such as dry eye. By understanding the causes, risk factors, and treatment options, individuals can make informed decisions about their eye health. Always consult with a qualified eye care professional for personalised advice and guidance.
