CK effective over the long-term

Article

Conductive keratoplasty (CK) is an effective long-term treatment for near-plano presbyopia.

Conductive keratoplasty (CK) is an effective long-term treatment for near-plano presbyopia, according to the results of a study published in the November issue of the Journal of Refractive Surgery.

Jason Stahl, MD from Kansas University Medical Center, Kansas, US evaluated the outcomes of 10 patients treated with unilateral CK, performed using the ViewPoint CK system (Refractec). Nine patients were available for follow-up at three years.

Preoperatively, the average manifest refraction spherical equivalent (MRSE) was -0.17 D and average near uncorrected visual acuity (UCVA) was J10. At three years follow-up, the mean MRSE had decreased to -1.06 D, representing a 0.25 D change from the average MRSE of -1.31 D at one year follow-up. Furthermore, at three years, all subjects had maintained an uncorrected binocular distance visual acuity of 20/20 and near UCVA averaged J3 or better in 78% of subjects.

Dr Stahl concluded that CK can be an effective long-term treatment for presbyopia.
