PS my eyes are -11.25 and -10.50 when the lenses are out I am blind...and no I can't do laser eye surgery.
Holy crap. From what i heard in my lectures, I think you may just qualify for some kind of surgery which embeds an artificial lens beneath the cornea in betwwen and behind the iris. Its not like laser surgery. Its like a permanent contact lens, except it stays with u for like 10 years or something..
go ask ur doctor
PS: Are there even contact lenses that support that kinda power? Arent they very thick and uncomfortable?
Me, I need a new prescription, last time was a few years (5?) @ -9 w/ some astigmitism. My mother is some where up around -13 or -14, but she just never got used to wearing contacts, too much of a hassle for her. And being elderly when she 1st tried wearing them, she had too much problems with dry eyes, needed constant re-irrigating with saline solution. So she's back to thick, very small diameter extra expensive glass lens, and specialty frames (plastic lens still can't beat glass for accuracy). Carl Zeiss used to license their proprietary thin glass lens tech, but US distributor withdrew them from the market because of USDA concerns about breakage, being so thin at the center. You can still get them through Canadian optometrists ~@$800/set, frame not included!
Sof-form II is a little larger in diameter than most (way back a decade or so ago, they used to make these enormously large dia lens that would supposedly not 'float' around in the eye as much as the typical small dia lens, but I tried these and my eyes were too irritated by the large diameter, so I keep blinking, and the lens never was comfortable), this helps to keep them 'centered' while blinking. They are also of a thin, but unique shape/profile which I find most comfortable compared to the smaller dia lens. Easier to take in, or out. Check with unilens for a retailer in your area.
Also with larger dia. Sof-form you add one drop of lens solution to the lens before inserting, this helps the lens 'roll' into the eye, while you hold the lower lid open for easy insertion. Two drops is usually too much, cause the lens to droop, or fold over before you get it placed into the eye.
Contacts go up to -20 & +20/

FWIW, Sof-form II is the older ~35% oxygen lens, and that's what I want in a daily wear lens. They have less water in them, so there is less to lose when your eyes dry out, meaning higher water content lens lose more water when your eyes dry out while sleeping, assuming you have the kind of eyes that get really dry. Reason, if you habitually leave the lens in over night, and your eyes dry out, over time (this could take a decade) blood vessels will grow into the clear part of your cornea...not good! The eye is oxygen depleted and tries to compensate. Take you lens out, no matter what type, what oxygen %. Trust me, ask a optometrist who has done contacts for more than a decade or so, and you'll find that some peoples eye have those blood vessels growing into the cornea, will cause loss of some vision over time, bad!
Keep fingers very clean, use a smaller cleaner solution, and the lens will stay clear longer, will not become plugged up with polutants that reduce the oxygen/water content of the lens. Smoking of any type will cause the lens to become polluted and turn yellow prematurely (not a problem with throw away lens, but I never use that type).
Also, you should always have the new prescription checked, as sometimes the lens is not ground to the precision it should be, ie. it's not exactly the correction specified in the prescription, and then you don't see as clearly as you should (has happened to me several times over a few decades of using/wearing them).
