Tied Out Open Sky technique: new method for iris fixation of intraocular lens in the absence of capsular support during penetrating keratoplasty

To describe a new method for iris fixation of intraocular lens in the absence of capsular support during penetrating keratoplasty. Its a new technique of iris fixation of intraocular lens without capsular support during penetrating keratoplasty. This technique is used in cases with a healthy iris and partial or total absence of capsular support during penetrating keratoplasty. Tied Out Open Sky is a technique easy to perform for iris fixation of intraocular lens during penetrating keratoplasty. The big advantage is being able to tie off the intraocular lens off the eye and fasten it securely.

Forward-angle incoherent photoproduction of pseudoscalar mesons off nuclei

The mechanism of forward angle incoherent photoproduction of pseudoscalar mesons off nuclei is revisited via the time-dependent multicollisional Monte Carlo (MCMC) intranuclear cascade model. Our results-combined with recent developments to address coherent photoproduction-reproduce with good accuracy recent JLab data of pi(0) photoproduction from carbon and lead at an average photon energy k similar to 5.2 GeV. For the case of. photoproduction, our results for k = 9 GeV suggest that future measurements to extract the eta ->gamma gamma decay width via the Primakoff method should be focused on light nuclei, where the disentanglement between the Coulomb and strong amplitudes is more easily achieved. The prospects to use heavy nuclei data to access the unknown eta N cross section in cold nuclear matter are also presented.
