Questions about piggybacked lenses

Because of a lousy LASIK surgery outcome I must wear rigid contacts.
But my eyes don't tolerate the hard lenses so I must also wear soft
lenses atop the hard. I've used Focus Night and Day but find them
difficult to handle because of the lack of tint. I'm trying Acuvue
Advance that has a milt tint and that makes it much easier to find in
the well. The soft lenses are plano. Do these have a curve? Does it
matter which side is against the eye? In fumbling them onto my eye
sometimes they adhere abruptly and at other times they don't adhere.
Is this because I'm getting the lenses backwards? When they don't
adhere it seems that they want to stay attached to my finger tip. How
can I tell whether the lenses are backwards?

Thanks in advance for any advice.

 

Chip,

Softlenses do have a curve even the plano ones.
When put on your fingertip they must have a "bowl'' shape when you view the
silhouette.
If they show a "plate'' shape then you put the lens in with the wrong side
attached to to cornea.
Bend the lens to the other curve.
If you are in doubt then look at both shape and pick the most rounded shape.
Sometimes it helps to let dry the lenses a little bit before placing them on
the cornea.
BTW, asked the manufacture or your specialist for a leaflet with
instructions.

Strange, an professional specialist should have given a directions for use.

Hope this helps,

Thanks for the help. It's been like pulling teeth to get any
assistance from this optometrist. First he wouldn't prescribe soft
lenses. When I showed him an abstract describing piggybacking he
relented. But noone has explained how to put these in. I balance the
soft lens on the tip of my index finger, then drip rewetting solution
into the lens. Then while forcing my eyelids apart with my other hand
I bend down to bring my eye to the lens. I routinely lost the Focus
lens by doing this. At least the Acuvue, having a tint, is easier to
find if it falls off my finger. Is this how it is supposed to be
done?

 

The weight of the saline makes them drop off the finger sometimes. Hard
to just put ONE drop in :-(

Sounds like what I do, except for the holding the eyelids apart bit:
Thumb = 1, little finger = 5. I put the lens (dry fingertip, couple
drops of saline in the lens) on the right #2 fingertip held horizontal,
bring my eye down toward it, pull the lower lid down with the right #3
fingertip, reach over the top of my head and pull my upper lid up with
the left #2, #3 and #4 fingers, and touch the lens to my eye.

I have a white breadboard thing that I put across the sink while I do
this. (A color would be much better because although my lenses claim to
have a handling tint, they don't. Really. One out of god knows how
many had a faint bluish tint. One.) On the breadboard I place a plate
right under my eye. Even so, I've managed to drop lenses into the
laundry basket below the sink, onto the floor outside the bathroom, and
on my own chest. I think the damn things have free will and they really
hate us.
