“…Laser in situ keratomileusis (LASIK) is the most commonly performed surgery to correct refractive error 1 and is especially popular among young adults, generally 20–40 years old 2 . LASIK remains the gold standard of laser refractive surgery since it first appeared, largely because it is a safe, effective and well‐established procedure that offers many advantages, such as fast and painless visual rehabilitation, low probability of regression and the absence of subepithelial corneal haze 1,3–5 .…”

PurposeTo assess the impact of computer use on the ocular surface of individuals after laser in situ keratomileusis (LASIK).MethodsThe dry eye symptoms and ocular surface of 18 post‐LASIK young individuals and 18 controls were evaluated before and after performing a 30‐min task on a computer without (Visit 1) and with (Visit 2) initial instillation of artificial tears. Symptoms were assessed using the Ocular Surface Disease Index (OSDI), Symptom Assessment in Dry Eye questionnaire version two (SANDE II) and Computer Vision Syndrome Questionnaire (CVS‐Q). The ocular surface was assessed by measuring corneal higher order aberrations, tear meniscus height (TMH), conjunctival redness, blink rate and incomplete blinking, lipid layer thickness (LLT) and non‐invasive keratograph break‐up time (NIKBUT).ResultsSANDE II scores were >0 after the computer task in both groups (p ≤ 0.01). SANDE II and CVS‐Q scores did not differ between LASIK and controls (p ≥ 0.43). Greater bulbar–temporal conjunctival redness, TMH and LLT and shorter NIKBUT were found after computer use in the LASIK group (p ≤ 0.04), whereas no changes were observed in the controls (p ≥ 0.20). Lower SANDE II and CVS‐Q scores were reported at Visit 2 compared with Visit 1 in both groups (p ≤ 0.01). Likewise, no worsening of dry eye signs was observed at Visit 2 (p ≥ 0.11).ConclusionsOcular symptoms reported during computer use were comparable between the groups. However, a worsening of dry eye signs was mostly observed in post‐LASIK individuals. The instillation of artificial tears was effective in preventing the effects of computer use on the ocular surface in post‐LASIK patients.
