What are my treatment options for severe dry eyes 1 month after ReLEx SMILE?
Therefore, firstly general measures would include taking regular breaks from prolonged visual work as well as avoiding cold dry environments if possible. This might include turning down the settings on air conditioners.
Beyond that, artificial tears are very helpful. If the dry eye is more severe, slightly thicker preparations that are preservative free would be preferred. These would include things like Optive Fusion, Systane Hydration, and other hyaluronate containing products. The drops should be used frequently, perhaps even every hour or so while the dryness is very bothersome. Besides these, gels such as Vidisic or Genteal are also helpful, and can be used perhaps 2-3 times a day. Being thicker, they help to maintain moisture around the eyes longer than more liquid preparations such as Tears Naturale or Refresh.
Another measure that can help to maintain a higher level of moisture around the eyes is punctal plugging. These plugs keep moisture around the eyes, and reduce the flow of tears or artificial tears away into the nose.
The above measures will be sufficient for the vast majority of post refractive surgery patients. Very occasionally, even drier eyes are seen, and some of them may be helped by preparing autologous serum (obtained from one's own blood) and using this as artificial tears. The various growth factors and natural proteins/vitamins in blood can help the corneal surface to heal in patients with more severe dry eyes.
Do consult with your doctor, to find out how your condition is, and to discuss which of these measures might be suitable for your particular case. Generally speaking, 1 month after refractive surgery is still considered quite soon after the operation, and you can expect spontaneous improvement (happening by itself) over the following few months.

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.
