ANATOMATICAL CONSIDERATIONS IN LENS CHOICE



Lid anatomy and position may be 
an important consideration.  For 
example, a patient with a very 
wide palpabral aperture where the 
upper lid is above the upper 
limbus, a flat cornea and requiring 
a plus lens may not be a good 
candidate for rigid lenses.  It is 
often difficult to get the lens to 
center on the cornea.  A hydrogel 
lens would be the lens of choice.
