Recentration of a small-aperture corneal inlay

We report 2 patients implanted with a small-aperture corneal inlay to correct presbyopia. After the surgery, both patients complained of visual symptoms and poor visual acuity. The distances from the center of the inlay to the corneal vertex center were 593 mu m nasally and 159 mu m superiorly in Case 1 and 72 mu m temporally and 17 mu m superiorly in Case 2. The 2 inlays were recentered at 2 weeks and 3 weeks postoperatively, resulting in significant improvement in the visual acuity and quality of vision. Accurate centration of a small-aperture corneal inlay seems to be an important factor in obtaining a satisfactory result. Recentration is possible and improves visual acuity if proper centration was not obtained after the first surgery.
