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.
