Corneal warpage resolution after refitting an RGP contact lens wearer into hydrophilic high water content material.
OBJECTIVE
We describe a case of corneal warpage caused by 14 years of rigid gas permeable (RGP) contact lens wear.


METHODS
The patient was refit with daily wear high water content soft contact lenses.


RESULTS
After 6 months there were significant changes in both refraction and keratometry; computerized videokeratography showed that the corneal contour of both eyes had normalized.


CONCLUSIONS
Knowledge of contact lens induced corneal warpage is limited; it is therefore nor possible to follow a standard protocol for managing patients with this corneal deformation. In the case described, it was possible to reestablish a normal cornea without completely suspending contact lens wear by changing from RGP to hydrophilic material.
