PURPOSE To evaluate difference in therapeutic outcomes between deep anterior lamellar keratoplasty (DALK) and penetrating keratoplasty (PKP) for the clinical treatment of keratoconus. METHODS A comprehensive search was conducted in Pubmed, EMBASE, Cochrane Library, and Web of science. Eligible studies should include at least one of the following factors: best corrected visual acuity (BCVA), p...

purpose: to evaluate the ability to predict visual outcome after penetrating keratoplasty (pkp) in patients with pseudophakic or aphakic corneal edema (pce or ace). methods: medical records of 34 patients (34 eyes) who underwent pkp for pce or ace during 1994-2004 in ahvaz were retrospectively analyzed for variables in the history and ocular examination before pkp and visual outcome after pkp. ...

BACKGROUND Although percutaneous kyphoplasty (PKP) could achieve rapid pain relief for the elderly with osteoporotic vertebral compression fracture (OVCF), some patients still had risks of suffering vertebrae delayed union which led to persisting pain and vertebral collapse. Preventing the delayed vertebral union could reduce the further morbidities and medical costs for patients with OVCF afte...

Penetrating keratoplasty (PKP) has a long track record of high success rates compared to other tissue and organ transplantations. Despite the immunologic privilege of the cornea, the issue of immunological rejection cannot be overlooked and endothelial rejection is observed in up to 20% of eyes undergoing PKP. 1 Repeat keratoplasties after rejection are increasingly more prone to rejection and ...

S U M M A R Y In an effort to confirm and constrain inner core rotation, we examine earthquakes from the South Sandwich Islands recorded at the Beijing Seismic Network. We obtained a total of 109 high-quality measurements of PKP(BC)-PKP(DF) differential traveltimes by waveform cross-correlations from earthquakes spanning over 30 years. The results show robust temporal changes in PKP(BC)-PKP(DF)...

UNLABELLED The management of amyelic thoracolumbar burst fractures remains controversial. In this study, we compared the clinical efficacy of percutaneous kyphoplasty (PKP) and short-segment pedicle instrumentation (SSPI). Twenty-three patients were treated with PKP, and 25 patients with SSPI. They all presented with Type A3 amyelic thoracolumbar fractures. Clinical outcomes were evaluated by a...

Objective: To compare the therapeutic efficacy of percutaneous kyphoplasty (PKP) with that of conservative treatment in elderly patients with osteoporotic vertebral compression fractures (OVCFs). Methods: A total of 80 elderly patients with osteoporotic vertebral compression fractures admitted to our hospital from January, 2013 to June, 2015 were randomly assigned by a random number table to re...

Several reports have shown that penetrating keratoplasty (PKP) is a safe and effective technique for corneal transplant and provides good visual outcomes1-3. However, such as Rathi et al.4 reported in a retrospective study, the incidence for cataract formation is high. In this study 24.45% of patients developed cataract within the first years of surgery, being the excessive use of steroids the ...
