my refraction was measured as
Refraction Jan 2019 (in this exam I just went for whatever made the lettering sharper and readable with my left eye, ignoring double vision)
OD: Sph -5.50 Cyl +1.50 Axis 048 VA - Dist: 20/20-1 ADD: 2.25
OS: Sph -7.00 Cyl +2.50 Axis 090 VA - Dist: 20/60- ADD: 2.25
Up to now, I have used astigmatism correcting contact lenses and glasses (mostly wearing the contacts).
Now I need to choose an IOL for my left eye cataract surgery.
I had LensStar topography readings, and some other machine I don't remember that were to assist in determining my astigmatism correction if I choose a toric lens.
I have some question about how astigmatism may be dealt with.
My inclination would be to get a Toric monofocal or Toric multifocal IOL. But this comes with the risk of it not being rotated correctly. In which case it is my understanding that a follow up surgery is done to correct the rotation.
But I've also read about laser incisions being used to correct astigmatism.
I like the idea of being able to continue wearing contact lenses (left eye included) if I find my distance and/or astigmatism correction after surgery is not where I want it in my left eye. Is there an advantage or disadvantage in using laser incisions vs a toric IOL in being able to further correct my post surgery vision in my left eye with contacts if necessary?
Does a toric IOL serve to halt the progression of my astigmatism? Does astigmatism continue to progress when corrected by laser incisions?
