Corneal iron ring after conductive keratoplasty.

چکیده
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 appearance of corneal iron ring deposits following conductive keratoplasty treatment in a patient. It is suggested that alterations in tear film stability, resulting from conductive keratoplasty-induced changes in corneal curvature, constitute the contributory factor for these deposits.

Secondary keratoconus with corneal epithelial iron ring similar to Fleischer's ring.
BACKGROUND Fleischer's ring is considered to be a characteristic of keratoconus, but we have seen a ring similar to Fleischer's ring in patients with secondary keratoconus, in which the cornea becomes thinner secondarily for undetermined reasons. CASES We report 6 cases of secondary keratoconus with a corneal epithelial ring similar to the Fleischer's ring pattern. OBSERVATIONS In these 6 c...
متن کاملConductive keratoplasty followed by collagen cross-linking with riboflavin-UV-A in patients with keratoconus.
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...
متن کاملCorneal perforation after conductive keratoplasty in a patient with previously undiagnosed Sjögren syndrome.
Conductive keratoplasty (CK) was approved by the US Food and Drug Administration in March 2004 for the correction of hyperopia ranging from 0.75 to 3.00 diopters (D) and 0.75 D or less of cylinder in patients older than 40 years. With CK, hyperopic correction is achieved through the use of a nonablative radiofrequency that shrinks corneal stromal collagen and steepens the central cornea. A kera...
متن کاملCorneal perforation after conductive keratoplasty with previous refractive surgery.
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...
