A 33 year old Asian male was diagnosed with corneal ectasia in the right eye several months after bilateral Lasik and was fitted with a rigid gas permeable contact lens in our center. During weeks and months of following visits, the ectasia gradually diminished to protrusion-free corneal shape with the aided visual acuity of 20/20 by the 11 months' time. Patient's cornea however did return to its ecstatic state in about 9 days once the rigid lens was ceased to wear as a test of corneal stability. During the follow up visit in 5 years later, without the trace of ectasia, a steeper base curve of rigid lens was needed for a better fitting pattern, suggesting the cornea had protruded further even under the event of lens wear. The rigid lens seems to have a biomechanical influence on patient's ectasia condition following Lasik.3enjournal article
