Dear student, If a person who has corneal problem located in
anterior part of cornea then there is no need to replace whole
cornea but only anterior part of cornea including epithelium,
Bowman's layer and stroma are replaced If a person presents with
disease of endothelium like Fuchs dystrophy etc ,we can replace
only posterior two layers So this way a single cornea can be used
in two corneal blind people Regards
