purpose: to study the effect of phototherapeutic keratectomy (ptk) in the treatment of various superficial corneal pathologies. methods: we performed a nonrandomized, prospective study on patients who presented with superficial corneal disease and/or poor vision. fifty eyes were included recurrent corneal erosion (rce): 25 eyes, salzmann’s nodular degeneration: 9 eyes, spheroidal degeneration: ...
The purpose of this study is to investigate the process of corneal wound healing after penetrating injury with the change in optical intensity on anterior segment optical coherence tomography (AS-OCT) and to investigate factors associated with severity of corneal scar. Forty-seven eyes from 47 patients with repaired corneal laceration were included. AS-OCT was performed on 1day, 1week, 1, 3 and...
Macromolecules from normal rabbit cornea and cornea containing a 2-mm diameter button of scar tissue were biosynthetically labeled with 35S-sulfate and 3H-glucosamine in vivo and in organ culture. Labeled macromolecules, including proteoglycans (PGs) extracted from the normal cornea, scar tissue, and corneal tissue adjacent to the scar with guanidine hydrochloride were chromatographed on DEAE-S...
Background and Objective: Astigmatism is a common complication of penetrating (PK) and Lamellar (LK) keratoplasty that may cause surgical failure due to visual disturbances. In this study, the efficacy of scar revision just at the surgical incision was evaluated. Materials and Methods: In this prospective interventional case-series study, scar revision was performed in nineteen post-PK or LK as...
purpose : the evaluation of the presence of herpes simplex virus (hsv) in corneal scars by real-time polymerase chain reaction (pcr) and comparison of the results with histopathologic findings and clinical diagnoses methods : eighty-seven corneal scar samples obtained after penetrating keratoplasty (pk), were selected after reviewing the records from 2006 to 2010. nucleic acid was extracted fro...
purpose: to determine the indications for and surgical techniques of corneal transplantation at labbafinejad medical center (lmc) from 2004 to 2007. methods: in this descriptive study, records of 756 patients who had undergone corneal transplantation from october 2004 to october 2007 were reviewed. results: overall, 504 male (64.9%) and 272 female (35.1%) subjects with mean age of 41.29±21.25 (...
A 40-years-old male patient with a corneal scar secondary to perforating eye injury had undergone ipsilateral rotational autokeratoplasty in our clinics. The corneal scar involved the pupillary area. The patient had a preoperative visual acuity of counting fingers. The patient's cornea was trephined with a 0.5 mm temporal decentration. The 8.0 mm autograft was rotated approximately 180° to relo...
BACKGROUND The performance and results of corneal tattooing are described in a case series of 11 patients suffering from a disfiguring corneal scar using a technique similar to conventional dermatography. METHODS Drawing ink in different shades was applied into the anterior corneal stroma by punctures performed with a conventional spatula needle. RESULTS Up to 4 years after surgery all pati...
purpose: to determine the indications for penetrating keratoplasty (pk) in iran over an 11-year period. methods: all eye bank records of patients who underwent pk from 1994 to 2004 at ophthalmologic centers throughout iran were reviewed. results: during this 11-year period, a total of 19,668 cases were operated. the most common indication for penetrating keratoplasty was keratoconus (34.5%), fo...
