There is an increasing demand for high-intensity subnanosecond lasers for emerging industrial applications. While femtosecond and picosecond laser sources are considered promising, they suffer from the significant drawbacks of increased complexity and cost. In this regard, we demonstrate a unique edge-pumped passively Q-switched Nd∶YAG∕Cr4þ∶YAG microchip laser. The microchip is made of a Nd∶YAG...

UNLABELLED Around 7%-10% of patients with obsessive-compulsive disorder (OCD) are refractory to first-line treatment. Neurosurgical approaches are available such as capsulotomy or deep-brain stimulation (DBS). There is strong evidence for central involvement of the corticostriatopallidothalamocortical (CSPTC) circuit in OCD, but the exact mechanism through which these interventions lead to clin...

PURPOSE To study the microanatomic edge structures of anterior lens capsule specimens derived from manual and femtosecond laser-assisted capsulotomies. SETTING Department of Ophthalmology, Goethe-University, Frankfurt, Germany. DESIGN Experimental study. METHODS Of 60 eyes with lens removal and intraocular lens implantation, 30 received a manual capsulotomy and 30 received a femtosecond l...

purpose: to evaluate the prevalence of concomitant systemic and ocular diseases in patients scheduled for phacoemulsification and intraocular lens implantation (pe+pc iol) and post surgical visual outcomes and complications in 1253 cases. methods: medical records of all patients of a private clinic who underwent pe+pc iol from 1999 to 2003 were reviewed. all operations were performed by a singl...

Background: To evaluate the visual outcome and complications of surgical membranectomy with modified incision capsulotomy microscissors in patients persistent pupillary membrane (PPM).

CASE REPORT We present the clinical case of a 68 year-old woman who developed a pupillary block acute glaucoma due to vitreous hernia into anterior chamber following posterior dislocation of the intraocular lens one month after an Nd:YAG capsulotomy. DISCUSSION We should consider these symptoms in the differential diagnosis of pseudophakic acute glaucoma, especially when visualisation of the ...

Since 1980, advanced lung carcinomas were treated with palliative laser therapy for the purpose of opening the endobronchial stenosis and obstruction by either photodynamic therapy (PDT) or Nd-YAG laser treatment at Tokyo Medical University. A total of 258 lesions were treated, 81 by PDT and 177 by Nd-YAG laser treatment. PDT achieved effective results in 61 (75%) of 81 lesions. In the Nd-YAG l...

Aim: To evaluate the efficacy of latanoprost for the prevention of ocular hypertension after neodymium: yttrium-aluminum-garnet laser posterior capsulotomy. Methods: Fifty six eyes of 56 consecutive patients receiving neodymium:yttrium-aluminum-garnet laser capsulotomy for posterior capsule opacification were randomized to group 1, who received 1 drop of latanoprost 0.005%, or to group 2, who r...
