6%) received dual HA reconstruction. HA complications were composed of thrombosis (n = 6), pseudoaneurysm (n = 2), and stenosis (n = 4), showing 3.2% (12/371) of incidence. In patients with HA thrombosis, whereas operative thrombectomies with re-anastomosis rescued all the grafts in early

attack (n = 3, <= 1 wk), angiographic thrombolysis successfully reestablished the flow in patients with late attack (n = 3, > 1 wk). In all patients with HA complications, except for one, all of our treatment modalities -operation and angiographic intervention-resulted AZD8186 research buy in successful rescue of grafts and no patient received re-transplantation because of HA complications.

Conclusion: Prompt diagnosis of HA complications by serial post-operative Doppler ultrasound and corresponding treatment strategies, including operative and radiological intervention, can rescue both grafts and patients without necessitating re-transplantation.”
“PURPOSE: To study spherical aberration, coma, and trefoil after implantation of a single-piece aspheric Tecnis intraocular learn more lens (IOL) in cataract patients and the influence on photopic

and mesopic contrast sensitivity.

SETTING: Ophthalmology Department, Ain-Shams University Hospitals, Cairo, Egypt.

METHODS: In this randomized prospective contralateral comparative study, patients had bilateral senile cataract Eyes with a pathological condition other than cataract that might influence postoperative

visual function were excluded The aspheric IOL was compared with the Sensar AR40e spherical IOL The IOL selection was randomized. Study criteria included corrected distance visual A-1210477 solubility dmso acuity (CDVA), wavefront aberrometry, and contrast visual acuity

RESULTS: Fifty-six eyes of 28 patients were enrolled All patients completed the 2-month postoperative visit There was no significant difference between the IOLs in CDVA (P> 05) Ocular spherical aberration was significantly lower with aspheric IOLs than spherical IOLs (P<.001). Two months after surgery, eyes with the aspheric IOL had better photopic contrast sensitivity and better mesopic contrast sensitivity at all cycles per degree. There was no significant difference in 3rd-order aberrations (coma and trefoil) between IOLs.

CONCLUSIONS: After cataract surgery, the single-piece aspheric IOL resulted in significantly lower ocular spherical aberration and significantly better mesopic contrast sensitivity. No significant difference in 3rd-order aberrations indicates that both IOLs had satisfactory centration in the capsular bag.
