Symptoms are not always obvious
Burning, grittiness, watering, fluctuating clarity, redness or discomfort after long screen sessions can be associated with ocular-surface problems. Some people have signs without strong symptoms, while others have significant symptoms with subtle signs.
Tell the surgeon what you experience rather than only asking for a dry-eye test score.
Why the tear film affects measurements and healing
An unstable tear film can affect the quality of refraction and corneal scans. It can also influence comfort and visual quality after treatment. Assessment may include the tear film, eyelids and ocular surface.
Sometimes the recommendation is to manage dryness first and repeat testing before deciding on surgery.
Screen use and other contributing factors
Long digital-device use, reduced blinking, contact lenses, environment, eyelid conditions, general health and medicines can contribute to symptoms. These factors do not automatically rule out surgery, but they help shape the plan.
Avoid starting or changing prescription medicines based on general website advice.
After LASIK: monitor rather than assume
Temporary dryness is common, and persistent symptoms are possible. Use only the drops and schedule prescribed for you, and report worsening discomfort or visual change.
Severe pain or sudden vision reduction is not a routine dry-eye complaint and requires prompt assessment.
