I just had my pupil dilated last night - this is
part of the pre-op work and check before my
LASIK surgery next Friday. It's now 1:30pm the next
day and my pupils have been dilated for the last 19 hours.
How normal is this?
I was given the usual Tropicamide and something else
I also had a nauseaous reaction last night after
the eye drops as well as right after lunch doubled
with going outside in the light. So we know I won't
be using these 2 together or at least in the strength
that they come in.
The usual regimen to dilate pupils includes tropicamide and phenylephrine. You mentioned proparaciane, however, this is a topical anesthetic drop and this is not used for dilation. Tropicamide is an anticholinergic which is used to dilate the pupils and decrease the ability to accomodate. Phenylephrine is a sypathomemetic drug which works in synergy to dilate the pupil. Neither of these is likely to cause nausea. Some people are sensitive to these drops and they may experience complain of feeling tired. Certainly, you will be sensitive to light in that your pupil cannot constrict and this allows alot of light to enter the eye. It is possible in some that dilating drops may cause the eye pressure to go up and this may be assoc with nausea, pain around the eye, and blurred vision. This is uncommon but a possibility. It is important to report these symptoms to your ophthalmologist because they can use a weaker strength of tropicamide (0.5% instead of the usual 1.0).
Good luck with your upcoming surgery.

I'm sure my eyes will go back to normal soon but I'm
concerned that the eye drop dosage was too strong?
What can you tell me about Tropicamide, Preparacaine and the
integration effects with food and light or other
chemical side effects.
