case_images: External photography showed a visible scar at the flap margin from 7 to 10 o'clock position (red arrow: the margin of the flap)

case_images: An incomplete flap with a visible scar at the flap margin was observed from 7 to 10 o'clock [Figure 1]. Corneal tomography results were normal [Figure 1].

case_images: Corneal tomography disclosed ectasia with anterior and posterior corneal surface protrusion over the lower temporal side [Figure 2].
case_images: The anterior segment OCT showed that the incision depth was deeper in the inferior cornea than in the superior side. OCT: Optical coherence tomography. (green arrow: the position of the OCT scan; white arrow: the incisional plane)

case_images: Anterior segment optical coherence tomography (OCT) showed an uneven plane of the corneal flap [Figure 3].

case_images: Conversely, the thickest residual stroma was found at the 10 o'clock position (residual stroma: 211 mum and flap: 484 mum) [Figure 4].
case_images: Tomography in the right eye 2 years later revealed the progression of corneal ectasia

case_images: The severity of right corneal protrusion worsened significantly can be seen by tomography [Figure 5].
