Mine is scheduled for Mid March and the Opthalmologist /surgeon should have given you many written pre and post operation instructions.
I have always not been shy about revealing my ignorance and asking questions (retired engineer,) and have been lucky in finding professionals who are inclined to answer all questions as thoroughly as I can understand, which is quite a bit. As explained to me...
The natural lens is a clear container which is full of liquid protein, which clouds over with time.
The protein is sucked out with the proper instrument through a slit cut around the edge of the lens, and the prescription lens (definitely not liquid) is inserted.
I did not inquire how the slit is sealed, but I will find out; I doubt that the slit in the lens is stitched closed.
The lens is manufactured to fit the contours of the individual eyeball, the rear retinal portion, and is formulated to provide 20-20 vision.
There is an optional varifocal lens which costs an extra $3200 per eye, which I opted out of since I have using reading glasses for years.
The pre op directions are elaborate and consists of two distinct eyedrops to be used twice a day for the 5 days before the procedure. There is also a post op follow-up the day after the procedure to verify everything is as expected.
Incidentally, the measurement of the eyeball for the specific prescription is determined with three specialized large instruments and provides dozens of measurements to determine the focal shape of the image at the rear of the eyeball.
I was pleased to learn that my sons' maternal grandfather had cataract surgery and it served him perfectly for the last 25 years of his life (at 102.)
Good luck to you.
$3200 per eye for the added reading prescription!? I paid $2000 per eye but probably because CA cost of living is higher.
