In order to model the thermal effect of laser exposure of the iris during laser corneal surgery, we simulated the temperature increase in porcine cadaver iris. The simulation data for the 60 kHz FS60 Laser showed that the temperature increased up to 1.23°C and 2.45°C (at laser pulse energy 1 and 2 [micro sign]J, respectively) by the 24 second procedure time. Calculated temperature profiles show...

Clinical and pathological investigations in a group of 113 patients with leprosy of long duration demonstrated the importance of iris changes as a cause of blindness. In lepromatous leprosy the so called "chronic iritis" produces iris atrophy with small nonreacting pupils which exaggerate the visual impairment created by developing lens changes and corneal opacities. The cause of this "chronic ...

Postoperative endothelial cell loss leads to graft failure after corneal transplantation, and is one of the important issues for long-term prognosis. The objective of this study was to identify clinical factors affecting graft survival and postoperative endothelial cell density (ECD) after Descemet's stripping automated endothelial keratoplasty (DSAEK). A total of 198 consecutive Japanese patie...

PURPOSE To report the distribution of iris conicity (steepness of the iris cone), investigate associated factors, and test whether pseudophakia allows the iris to sink back. METHODS A population-based cross-sectional study was carried out. Ophthalmological examination including objective refraction, biometry, noncontact tonometry, and Scheimpflug imaging (Pentacam®, Oculus) was performed incl...

Marfan syndrome (MFS) is a genetic disorder which is inherited by autosomal dominant traits. In MFS, lens displacement and cardiovascular involvement are important causes of morbidity and mortality in the clinical course of the disease. In this case study, the ocular involvement in a family with severe penetration of MFS is reported. Twelve members of a family (father, two daughters, three sons...

Ocular coloboma is a rare malformation which occurs as an isolated defect in healthy individuals or be part of complex syndrome known unknown etiology. Patients with iris and choroid complicated cataract should have surgery to improve their BCVA, if there no retinal detachment.We report the case right eye male following consultation.The patient had inferonasal iris, resulted pear-shaped pupil l...

Five infants with biopsy proved juvenile xanthogranuloma of the iris were reviewed. Early treatment with subconjunctival injection of steroids and topical steroid drops resulted in regression of the lesion in four patients. One patient, reviewed at the age of 8 months after glaucoma which had developed secondary to the iris xanthogranuloma, had been treated by surgery alone: the visual outcome ...

PURPOSE To report the results of cataract surgery after previous implantation of an Artisan iris-fixated phakic intraocular lens (pIOL) for the correction of myopia. SETTING University center and private practice. METHODS This study comprised eyes with previous implantation of an iris-fixated pIOL to correct myopia and subsequent pIOL explantation combined with cataract surgery and in-the-b...

PURPOSE To show surgical solutions in patients with traumatic and congenital aniridia, to evaluate the clinical improvement of these patients when iris prosthesis are implanted, and to examine safety and complications of these implants in a long-term follow-up. METHODS Eight patients were included in this retrospective noncomparative case series. Nine eyes had an artificial iris implantation ...
