PURPOSE To report formation of corneal iron ring deposits after conductive keratoplasty. DESIGN Observational case report. METHODS Case report. RESULTS A 54-year-old woman underwent conductive keratoplasty for hyperopia. One year after conductive keratoplasty, iron ring pattern pigmentation was detected at the corneal epithelium of both eyes. CONCLUSIONS This is the first report of the ...

purpose : to present conductive keratoplasty (ck) as a new procedure to correct residual hyperopia and astigmatism after phacoemulsification surgery and to evaluate its predictability, safety and stability methods : fifteen eyes of 13 patients with preoperative hyperopia +0.75 to +3.00 d and or astigmatism -0.75 to -3.00 d were enrolled into the study and underwent ck treatment. at the 1st and ...

PURPOSE To evaluate the combined effect of conductive keratoplasty (CK) followed by corneal collagen cross-linking (CXL) in 2 patients with keratoconus. METHODS CK spots were applied on the flatter side of the cornea followed by CXL using riboflavin and UV-A light. RESULTS Immediately after CK, a significant corneal topographic improvement was observed. The CK effect regressed 3 months post...

PURPOSE To determine the morphologic changes in human corneas over time following radiofrequency-based conductive keratoplasty (CK) treatment. DESIGN Prospective, observational case series. METHODS In a single-center study six human corneas of six patients with localized peripheral keratoconus underwent CK treatment followed by penetrating keratoplasty. Three spots were applied in the perip...

BACKGROUND/PURPOSE Conductive keratoplasty (CK) is a surgical technique that delivers radio frequency (350 kHz) current directly into the corneal stroma through a Keratoplasty tip inserted into the peripheral cornea at 8 to 32 treatment points. A full circle of CK spots produces a cinching effect that increases the curvature of the central cornea, thereby decreasing hyperopia. We report here th...

PURPOSE To assess the long-term safety, efficacy, predictability, and stability of conductive keratoplasty (CK) for the treatment of low to moderate hyperopia and to evaluate the impact of the procedure on the quality of vision. SETTING University of Crete, Medical School, Vardinoyannion Eye Institute of Crete, Crete, Greece. METHODS In this prospective nonrandomized noncontrolled single-ce...

PURPOSE To evaluate the safety, efficacy, predictability, and stability of conductive keratoplasty (CK) for the treatment of hyperopic astigmatism. SETTING University of Crete Medical School, Vardinoyannion Eye Institute of Crete, Heraklion, Greece. METHODS In this prospective nonrandomized noncontrolled single-center study, 47 eyes of 34 patients (15 women and 19 men) were treated for hype...

PURPOSE To assess the outcomes of conductive keratoplasty (CK) for patients with complications related to LASIK or photorefractive keratectomy (PRK). DESIGN Retrospective, noncomparative, interventional case series. PARTICIPANTS Sixteen eyes of 15 patients were treated using CK after complications of initial LASIK or PRK surgeries. Five cases are described in detail. INTERVENTION Rehabili...

A 56-year-old woman had conductive keratoplasty (CK) for residual hyperopia and astigmatism. Three years before the procedure, the patient had arcuate keratotomy, followed by laser in situ keratomileusis 2 years later for high astigmatism correction in both eyes. During CK, a corneal perforation occurred in the right eye; during the postoperative examination, an iris perforation and anterior su...

PURPOSE To define the corneal optics of conductive keratoplasty (CK) and assess the clinical implications for hyperopia and presbyopia management. METHODS Four analyses were done. (1) Multifocal effects: In a prospective study of CK, uncorrected visual acuity (UCVA) for a given refractive error in 72 postoperative eyes was compared to control eyes. (2) Surgically induced astigmatism (SIA): 20...
