Conductive keratoplasty is a noninvasive, in-office procedure for the correction of hyperopia, hyperopic astigmatism, and management of presbyopia. It serves as an alternative to laser-based refractive surgery with essentially no intraoperative or postoperative complications.
In the past decade, photorefractive keratectomy and laser in-situ keratomileusis have been the most popular refractive surgical procedures to correct myopia, hyperopia and astigmatism. Although relatively safe, flap-related complications often result in undesirable visual acuity. Since US Food and Drugs Administration approval in 2002, conductive keratoplasty has become a promising technique to correct low to moderate hyperopia and astigmatism. The procedure was first used by Mendez and colleagues in 1993. It is a nonlaser, no cutting procedure that delivers radio-frequency energy to corneal stroma in a circular fashion to steepen the cornea. Multiple studies have shown that conductive keratoplasty offers equal or superior efficacy, predictability, stability and safety than currently used refractive procedures to correct hyperopia or hyperopic astigmatism. In addition, monovision conductive keratoplasty has been shown to be successful for the management of presbyopia.

传导性角膜成形术是一种用于矫正远视、远视散光和治疗老花眼的非侵入性门诊手术。它是基于激光的屈光手术的替代方法,基本没有术中或术后并发症。
在过去十年中,准分子激光原位角膜磨镶术和飞秒激光制瓣准分子原位角膜磨镶术一直是矫正近视、远视和散光最受欢迎的屈光手术。虽然相对安全,但与瓣相关的并发症常常导致不理想的视力。自2002年美国食品药品监督管理局批准以来,传导性角膜成形术已成为矫正低度至中度远视和散光的一种有前景的技术。该手术于1993年由门德斯及其同事首次使用。它是一种非激光、无切削的手术,以圆形方式将射频能量传递到角膜基质,使角膜变陡。多项研究表明,与目前用于矫正远视或远视散光的屈光手术相比,传导性角膜成形术具有同等或更好的疗效、可预测性、稳定性和安全性。此外,单眼视传导性角膜成形术已被证明在治疗老花眼方面是成功的。
