Slit-lamp examination of the OHB in case 1 (a). Excision of the OHB (c). Corneal total higher-order aberrations before (b) and after bleb excision (d) with the simulated retinal images of Landolt C from corneal total higher-order aberrations on the right side.

A slit-lamp examination of the left eye revealed a large OHB; the anterior chamber has a normal depth and the lens status was IOL (intraocular lens) (Figure 2(a)). There was a slight leakage around the fornix margin of the excision, but it stopped naturally on postoperative day 5 (Figure 2(c)). The symptom of constant foreign body sensation was also reduced, and improvement of poor cosmetic was also seen (Figures 2(b) and 2(c)).

A slit-lamp examination of the right eye revealed an OHB; the anterior chamber has a normal depth and the lens status was IOL (intraocular lens) (Figure 3(a)). No leakage was observed around the margin of the excision following the operation (Figure 3(c)). Simulated retinal images of Landolt C based on corneal wavefront data had clearly improved with reduced total corneal HOAs (Figures 3(b) and 3(d)).
