To evaluate efficacy and safety of combined Intacs and Conductive Keratoplasty (CK) for patients with keratoconus.
A retrospective non–comparative case series of nine patients who were treated using Intacs and CK for keratoconus was performed. Clinical outcome measures including UCVA, BCVA, manifest refraction, keratometry measurement and topographic analysis were reviewed.
Mean preoperative distance UCVA was 20/262 and BCVA was 20/38. Mean manifest refraction spherical equivalent was –5.85D (SD 3.65; range, –1.38 to –12.75). Mean refractive cylinder was 5.13D (SD 3.15, range, 2.75 to 13.0). Mean preoperative keratometry measurement was 48.67D (SD 4.80, range 42.5 to 56.5). Postoperative mean UCVA improved to 20/159, an average of 1.3 lines of vision. No eyes lost > 1 line of UCVA. Mean BSCVA after Intacs and CK was 20/39. Three eyes showed an improvement of 1 line of BSCVA, 5 eyes had no change, 1 eye worsened by 1 line. Manifest refraction spherical equivalent improved to –1.89D (SD 3.13), ranging from –4.0 to +1.63D. The mean change in cylinder was a reduction of 1.25D. The mean change in keratometry was 1.46D. Videokeratography findings showed an overall flattening of the corneal surfaces (mean simK change) of 1.02D.
We report good visual results following Intacs and CK surgery for keratoconus. This unique combination of procedures offers additional corneal remodeling options for the surgeon and keratoconic patient.
