CASTROVEJO (1955) stated that opacities of the cornea, provided that they did not involve the whole thickness might be removed by clean dissection of the affected external layers. If infection, formation of granulation tissue, or revascularization is prevented during the post-operative period, the epithelium grows over the dissected area, the cornea remains transparent or fairly transparent, an...

PURPOSE To evaluate the results of transscleral fixation of dislocated posterior chamber intraocular lenses (PC IOLs) by externalizing the haptics through a clear corneal incision. SETTING Department of Ophthalmology, Rassoul Akram Hospital, Iran University of Medical Sciences, Tehran, Iran. METHODS This retrospective interventional case series comprised 21 eyes (21 patients) in which a dis...

PURPOSE To compare the astigmatic outcomes of phacoemulsification cataract surgery using temporal versus nasal clear corneal incisions. METHODS In a clinical trial, consecutive patients with senile cataracts underwent phacoemulsification and implantation of a hydrophobic acrylic foldable intraocular lens through a horizontal clear corneal incision (temporal in right and nasal in left eyes). O...

BACKGROUND A new type of corneal opacity with prominent corneal nerve fibers as an ocular complication of spondyloepiphyseal dysplasia tarda (SEDT). CASE A 58-year-old woman, diagnosed with SEDT at 5 years of age, underwent a complete ophthalmological examination. OBSERVATIONS The patient had no complaints and no history of eye disease. No relatives were reported to have suffered from SEDT....

OBJECTIVES To describe the ophthoselfie, a method by which everyone can take detailed self-images of the cornea and anterior segment with a smartphone. MATERIALS AND METHODS A 90-diopter non-contact double aspheric lens was attached to posterior camera of the smartphone by clear tape. Images of one eye on the screen of the smartphone could be seen with the other eye in the mirror and images w...

The anterior one-fifth of the human eye is called the cornea. It consists of several specialized cell types that work together to give the cornea its unique optical properties. As a result of its smooth surface and clarity, light entering the cornea focuses on the neural retina allowing images to come into focus in the optical centres of the brain. When the cornea is not smooth or clear, vision...

We developed cell-free implants, comprising carbodiimide crosslinked recombinant human collagen (RHC), to enable corneal regeneration by endogenous cell recruitment, to address the worldwide shortage of donor corneas. Patients were grafted with RHC implants. Over four years, the regenerated neo-corneas were stably integrated without rejection, without the long immunosuppression regime needed by...

Temperature has been used to diagnose human’s health since 400 B.C. where Hippocrates reported disease is to be found whichever part of human body is in excess heat or cold. This idea is still widely applied nowadays and the advance in infrared thermography technology is furthering the idea into more sophisticated diagnosis techniques, such as detection of breast cancer. Detection of ocular dis...

purpose: to determine bacterial contamination of corneas and corneal storage media provided from the eye bank of i.r. iran to rasool akram medical center. methods: this descriptive study was performed on 70 corneoscleral rims and corneal storage media. one milliliter of corneal storage media and the corneoscleral rim were sent to microbiology laboratory at the time of penetrating keratoplasty a...

to evaluate long term safety and efficacy of the photo refractive keratectomy (prk) in myopic eyes with thin cornea, this study has been designed. in this retrospective case series study, we included 74 eyes of 38 myopic patients with preoperative central corneal thickness (cct) less than 550 micrometer who underwent for prk surgery prior to 2010 and had 4 years of mean follow up postoperativel...
