LASIK is a popular choice for corrective eye surgery, which is considered safe, effective and highly successful. But this eye surgery comes with its own share of side effects. One of the most common problems patients face after post-LASIK is feeling dryness in the eye or simply “dry eyes”. According to Optometrists.org, around 95 percent of post-LASIK patients report symptoms of dry eye for up to a few days or weeks post-surgery. However, some practices and procedures before LASIK can help prevent or reduce dry eye symptoms. Let’s explore.
Why LASIK lead to dry eyes?LASIK temporarily disrupts the corneal nerves that are responsible for stimulating tear production, which ultimately reduces tear secretion, leading to dry eye symptoms.
1. Dry eye evaluation
A study in the Investigative Ophthalmology and Visual Science Journal has shown that preoperative tear volume and tear-film stability strongly influence post-LASIK outcomes. This means that someone with asymptomatic dry eye only notices the problem after surgery.
2. Omega-3 fatty acids for selected patients
A controlled clinical study in The Journal of Cornea and External Disease found that omega-3 supplementation before LASIK improved tear secretion, though effects on tear stability varied. This suggests omega-3 fatty acids can help deal with dry eye problems but only in certain patients.Note- These supplements should only be taken after consultation with a professional.
3. Temporal punctal plugs
According to Cleveland Clinic, Punctal plugs are tiny devices that a healthcare provider can insert into your puncta, the small openings that drain tear fluid from your eyes. These devices slow or stop tear fluid drainage, reducing or preventing dryness in your eyes.A study in the Indian Journal of Ophthalmology reported that punctal plugs reduced dry eye symptoms by about 13% and delayed symptom onset by over 30 days without affecting visual outcomes. However, it is important to consult with the surgeon about its effectiveness.
