this work is a report 0/9 cases ofarcuate incision for correction 0/astigmatism, after penetrating keratoplasty. plannings were based ojj corneal topography, and the first operation was always arcuate incision alone. 11,e secondary plans were based on refractive errors. the mean of preoperative astigmatism was 6d with the range of5 to 9/). after arcuate incision a/the graft-host interface in th...

purpose : to investigate tear film status after phacoemulsification surgery with temporal and supratemporal clear corneal incision in a cohort of patients with senile cataract methods : we enrolled sixty eight eyes of 68 patients with senile cataract requiring phacoemulsification in a prospective, cohort study. all patients undergone basic tear secretion test (btst), tear meniscus height (tmh),...

a nulliparous non-descript mare was presented with a complaint of dystocia. the mare was recumbent and physical examination revealed that the animal was in shock. there was no straining and foetal forelimbs were visible outside the vulva. the foetus was dead as there was no pedal reflex. vaginal examination revealed anterior presentation with dorso-sacral position and rigid lateral head deviati...

Analysis of the effects of deoxycholate and benzalkonium chloride on granule relaxing activity, myofibril and glycerinated fiber responses to ATP, and the sensitivity of these actomyosin-containing systems to relaxing factors have established that it is possible to differentially inactivate intrinsic granule relaxing factor. It is therefore possible to use these agents to treat myofibrils and g...

T he treatment of moderate to high astigmatism is challenging for the refractive surgeon. Even in experienced hands, 40% of patients who undergo penetrating keratoplasty (PKP) are left with more than 4.00 D of astigmatism.1 Spectacles, contact lenses, excimer laser ablation, toric IOLs, and tissue-relaxing procedures have been used for a long time in the treatment of preexisting and postsurgica...
