One of the most important risk factors for Dry Eye are some ocular surgeries, such as cataract and refractive surgeries, like nearsightedness (myopia), farsightedness (hyperopia), presbyopia or astigmatism—being LASIK (i.e., laser-assisted in situ keratomileusis) the most popular method applied.
After performing this type of surgery, most patients experience some eye disorders associated to the surgery, especially Dry Eye Disease (DED).
In people with unstable tear film, there may be variation of more than 1.0D, which can correspond to an error of the same magnitude in lens power calculation and thus significantly impact vision.
Beatrice Cochener-Lamard, MD FACS
Unresolved ocular surface disease (DED) represents a major risk factor for suboptimal outcomes in refractive surgery. Untreated preoperative dry eye disease (DED) and meibomian glands dysfunction (MGD) can impact the accuracy of refractive calculation and contribute to poor vision outcome. Existing DED, both asymptomatic and symptomatic, can be exacerbated during surgery and lead to postoperative patient dissatisfaction with their cataract procedure.
