RGPs - more likely to lose them if large/small?

Discussion in 'Optometry Archives' started by Pipino Il Breve, Dec 23, 2003.

  1. ROAR!! I have lost an RGP out of home without realizing :-((

    I can choose 2 equally valid diameters (not BCs) for RGP lenses for my
    eyes. I am now considering the next purchase: do you think it is more
    likely to lose a larger-diameter lens, or a smaller-diameter lens?

    (I'm speaking about diameters being around 9.40: it's not a full cornea

    Thanks in advance

    Pipino, there is no straight answer.
    BTW, it is a long time ago that you had problems with contactlenses.
    Is the switch from softlenses to RGP lenses making this possible?
    Anyway, glad it is working fine.(except for losing one)

    Generally, larger is less likely to be "lost", but not necessarily as it
    depends upon lid position and tightness, peripheral curvature and edge

    And, by the way, when you increase the diameter, the lens oftentimes
    requires a completely different set of peripheral curves and edge
    configuration. If it ashperic, it requires a different eccentricity
