Ocular characteristics associated with rigid gas-permeable lens adherence

摘要: ABSTRACT Purpose. Rigid gas-permeable (RGP) lens adherence after overnight wear is clearly a patient-dependent phenomenon. However, no previous study has attempted to determine whether specific ocular characteristics are associated with an increased frequency of adherence. Method. In this study, clinically applicable tests were used measure range characteristics, including central and peripheral corneal curvature, tear film status, eyelid thickness, rigidity in group 22 young adult subjects for whom reliable estimates RGP had been obtained from earlier studies. Results. Linear discriminant analysis revealed that higher was lower rigidity, thinner corneas, greater tension, amounts astigmatism. Conclusions. These findings suggest clinical approach identifying patients who may develop significant during extended wear, also provide support the “thin adherence” theory
