CONTRAINDICATIONS TO LENS WEAR
GENERAL HEALTH REASON:
Pregnancy
During pregnancy the tear film may
change causing wearing problems.
There may be water retention
causing corneal edema
Some patients have problems with
lens wear particularly during the first
3 to 6 months of a pregnancy. Patient
should be allowed to wear lenses
during pregnancy but it is usually
prudent not to fit a new patient during this time.
Thyroid Dysfunction
Hypothroidism may cause dryness and difficulty with lens wear. Patient should be controlled with medications before being fitted.
Hyperthyroidism can cause exophthalmos with resultant drying and fitting problems.
