Dry eye is a common and often chronic condition nowadays regardless whether one has had any laser surgery done. This is especially so when most of our days revolve around working at a computer or other electronic devices, where we tend to blink less fully and less frequently. Blinking actually helps in lubricating the surface of the eye.
A healthy tear film consists of the lipid, aqueous and mucous layers on the corneal surface. The main cause of dry eye is an imbalanced tear-flow system whereby there is decreased tear production and/or increased tear evaporation and drainage, affecting the quality of tear composition.
Common treatments for dry eye include using preservative-free artificial eyedrops and ointment. However, if dry eye still persists, it is important to address the root cause.
Additional treatments include increasing tear production with formulated medication, insertion of punctal plug to slow down tear outflow and warm compress when the underlying cause of dry eye is simply due to increased tear evaporation as a result of blocked oil glands around the lid margins.
The causes of dry eye can be multi-factorial. Hence, it is advisable to have a comprehensive eye examination with your eye doctor to identify the root and discuss available treatment options.
