Clinical Outcomes of Monovision Induced by Presbyopic Correcting Conductive Keratoplasty

ABSTRACT

PURPOSE: To evaluate the efficacy, safety, and satisfaction of patients who underwent conductive keratoplasty (CK). METHODS: CK was performed in 20 patients between April and December 2009. Surgeries were performed on the dominant eye with emmetropia as the postoperative goal and on the non-dominant eye with mild myopia as the postoperative goal. Patients' satisfaction, refractive change, and visual acuity were evaluated for at least 3 months after the surgery. RESULTS: Preoperatively, the mean manifest refraction spherical equivalent (MRSE) of the non-dominant and dominant patient eyes was 0.56 +/- 0.48 D and 0.88 +/- 0.25 D, respectively. Postoperatively, the mean MRSE of the non-dominant and dominant patient eyes was -1.65 +/- 0.56 D and -0.06 +/- 0.36D at 1 month, -1.33 +/- 0.40 D and 0.17 +/- 0.37 D at 3 months, and -1.10 +/- 0.44 D and 0.31 +/- 0.33 D at 6 months, respectively, indicating significant effect regression. Eleven out of 20 patients (55%) were disappointed with the results of CK. CONCLUSIONS: Conductive keratoplasty led to significant regression of refractive effects during follow-up. Monovision with CK is suggested to be a temporary refractive procedure in patients with presbyopia.
