Ipsilateral rotational autokeratoplasty is a useful alternative to other techniques such as optical iridectomy, penetrating keratoplasty and keratoprosthesis for the management of high-risk cases with full-thickness corneal scars.1 2 3 Case selection and surgical planning are the key requirements for performing this procedure. Previously, complex equations have been described to select cases and determine the graft size and position of the host cut.4 5 6 We describe a new method, computer simulation-assisted rotational autokeratoplasty, for case selection and surgical planning of ipsilateral rotational autokeratoplasty.

Materials and methods

Technique of computer simulation-assisted corneal autorotation

Five cases with partial corneal opacification (table 1) were selected. A comprehensive ophthalmic examination, including evaluation of posterior segment, was undertaken to rule out any associated pathologies. A central photograph of the eye, taken using the Haag Streit slit lamp (Photo Slit lamp 900 P-BQ; Haag-streit, …
