Transepithelial photorefractive keratectomy for the management of hyperopic regression after conductive keratoplasty

Abstract

Several refractive techniques are available for the treatment of hyperopia. Conductive keratoplasty (CK) is a safe and non-ablative procedure suitable for the treatment of low hyperopia and presbyopia. Due to the high rate of regression, it is not a commonly used technique. There is minimal literature about the use of refractive procedures for the treatment of hyperopic regression after CK. We report a case of a 49-year-old man who had undergone bilateral CK 15 years before for the correction of his hyperopia. He experienced a regression, with sph +2.75 cyl −0.50(20) in the right eye and sph +2.50 cyl −0.75(170) in the left eye. Transepithelial photorefractive keratectomy (tPRK) was performed with Schwind Amaris 750 s. After 12 months, his best-corrected visual acuity was 20/20, with −0.25 sph in both eyes. To the best of our knowledge, this is the first reported case of tPRK performed after CK.

Choosing the right surgical treatment for hyperopia

“…These include laser refractive surgery (LRS), phakic lens implantation and refractive lens exchange (RLE). Conductive keratoplasty (CK) has been abandoned by majority of surgeons due to the high rate of regression and low predictability [2].…”
