Annual examinations include assessment of the children's ability to focus their eyes, their eye glass prescription, the length of their eyes, detailed maps of the shape and thickness of their corneas (the clear window on the front of the eye), the shape of their eyes, and the curvature of the lens inside the eye. Their eye glass prescription is determined when the children's eyes are dilated. We examined 222 children for eligibility. Out of the 222 children, 148 were eligible to participate in the run-in period. Of the 148 eligible children, 116 (78.5%) were able to adapt to rigid gas permeable contact lens wear. All of the children were examined at The Ohio State University College of Optometry.
