Question:
I have a question about needing to stop wearing soft contact lenses before
cataract surgery. I
am in the queue for cataract surgery in the UK. I am scheduled for the
measurement exam on 17 July and they have told me I must remove the left
Permalens extended wear soft contact lens two weeks before the exam. I have worn
Permalens contact lenses for 35 years and do not own glasses. I sleep in my
lenses and change them once a month. I am very nervous how I will manage with
only one lens. With Permalens lenses being so thin do I really need to remove
one for 14 days? I will not be able to get to work, let alone work. Will 10 days
be long enough? Could it be shorter with Bausch & Lomb contact
lenses lenses?
Answer: Proper
discontinuation of soft contact lens wear prior to Cataract Surgery measurements
is a necessary and important step in allowing your Cataract
Surgeon to obtain the best possible measurements for the calculation of the
Lens Implant power. While Rigid Gas Permeable (RGP) contacts do cause
significantly greater shape change in the cornea, extended wear contact lenses
such as you have been using also can cause meaningful changes in corneal
thickness and ultimately curvature. Someone who has worn extended wear contact
lenses for 35 years needs to be certain that the cornea has fully returned to
its normal physiology, shape and thickness prior to Lens implant measurements
and certainly prior to the actual Cataract
operation. Do not be surprised if after the initial measurement you are
instructed to leave your contact lenses out for an even longer time in order for
your Cataract Surgeon to fully confirm that all of the measurements are stable.
it would be wise to carefully follow your eye surgeon's instructions.
