Although the prevalence
of dry eye has been
reported to range from
8–34%, it tends to be
under recognized and
under diagnosed (Figure 1).1,2
Ocular surface health is critically
important to vision quality—particularly
after cataract and
refractive surgery.
Historically,
dry eye disease (DED) and ocular
surface disease (OSD) were not
mainstream topics because our
understanding of the pathophysiology
of the disease process was
limited, as were our diagnostic
and treatment modalities.
We hope our new paradigm
of point-of-care testing will drive
awareness of the importance
of DED and OSD and how
they relate to the presurgical patient.
Moreover, we hope
these assessments will help us
diagnose this condition even
before symptoms develop.
Effects of OSD
Because the tear film is the first
refractive surface that light encounters,
an unstable tear film reduces vision quality and adversely
affects preop testing and
postop vision quality.
Epitropoulos et al. showed
significant variation in average K
readings and resulting IOL power
calculations in patients with
elevated tear osmolarity.
