Why Can LASIK Lead to Dry Eyes?
LASIK and other vision correction procedures involve penetration of the eye surface, which can lead to reduced
corneal nerve sensitivity. Dry eye can result if your eyes struggle to sense when they need to produce tear lubrication after the surgery.
Who Is Most At Risk?
Dry eye is a common side effect of LASIK surgery for both
people who suffer from the condition before the procedure and those who have
never experienced dry eye. However, those with higher degrees of myopia tend to
be more at risk for dry eye because these patients require a deeper removal of
corneal tissue to reshape the eye. More significantly, for 25% of patients, dry
eye symptoms are found to persist for up to six months after surgery. Older
age, certain allergies, autoimmune diseases can also contribute to dry eye, so
patients who fit these criteria should be extra aware of the potential dry eye
side effects of these procedures.
So What Should You Do?
Doctors often recommend that patients attempt to treat
current dry eye conditions before undergoing LASIK. In addition, doctors may
recommend that even patients with normal tear production use dry eye
treatments as a preventative measure before surgery. People with and without dry
eye might be encouraged to take fish oil supplements in the weeks before
surgery in order to improve the tear film. MedOp carries a product called MaxiTears containing
Omega-3 fish oils that is specifically formulated for dry eye sufferers looking to
improve their tear production. After surgery, patients might find relief by
using EyeEco’s soft flexible goggles called Tranquileyes. The product comes
with reusable gel packs to be used within the goggles that provide eye hydrating therapy to soothe and restore dry, tired eyes. The goggles create a humid, warm
environment around the eyes to helps stimulate tear production and slow the
evaporation of tears. Of course, dry eye relief may be found through a number of options. For ideas on how to combat dry eye, especially during these summer months, check out our blog "Beat Your Dry Eye This Summer".
