After LASIK surgery in 2016, I?m still dealing with dry eye symptoms and using Systane Ultra 4 times a day, but I?m thinking of switching to a cheaper option like Ocumoist because I?m worried about long-term use and preservatives in my eyes. Is it safe for me to change and continue using it regularly?

Dry eye after LASIK can continue for many years because the tear film may remain unstable after surgery, so needing lubricating eye drops regularly is quite common. Long-term use of artificial tears is generally considered safe, especially if the drops are preservative-free, since frequent exposure to preservatives can sometimes irritate the eye surface over time. Switching from Systane Ultra to a more affordable option like Ocumoist is usually reasonable if it provides similar comfort and relief for your eyes. Different brands suit different people, so the main thing is whether your symptoms stay controlled without extra irritation, burning, or blurred vision. If possible, choosing a preservative-free version is better when drops are needed multiple times daily. Along with eye drops, regular blinking, limiting long screen exposure, staying hydrated, and avoiding direct air from fans or AC can help reduce dryness. If symptoms are worsening or if you develop pain, redness, light sensitivity, or changes in vision, it is important to get an eye check-up to reassess the condition properly.
