Lasik & The Weather

Postby DryEye » Mon Jul 17, 2006 9:34 pm

What are your thoughts about how having lasik done in the summer months may affect one's result vs the winter months? Also, post lasik can one's vision quality be slightly affected by weather conditions (ie high humidity & heat days vs non)?
Thanks!

A laser is simply light passing through the atmosphere. Being light, it can be disrupted by anything that is in that atmosphere. Dust, perfume, humidity, even the atmospheric pressure (amount of air per square inch) can affect the laser.

All good surgeons adjust their surgery plan based upon known variables. The obvious is the patient’s prescription, but the less obvious is something like relative humidity and atmospheric pressure. Many doctors keep the surgery suite with a stable and specific level of relative humidity.

Recently an optometrist was misquoted, moving a decimal point that indicated the possible effect of atmospheric changes could be dramatic. In reality, it is a very small change that can be accommodated by knowledgeable adjustments.

Regarding recovery, Lasik tends to temporarily induce dry eyes so there may be some advantage to recovering in an environment that has relatively high humidity, but someone in a low humidity environment can remedy the situation with the application of preservative-free artificial tears.
