“PURPOSE: To report the incidence of visual axis opacification (VAO) requiring surgery after cataract extraction with hydrophobic acrylic intraocular lens (IOL) implantation during the first year of life.
SETTING: Storm Eye Institute, Charleston, South Carolina, USA; Iladevi Cataract and IOL Research Center, Ahmedabad, India.
DESIGN: Cohort study.
METHODS: Medical records of patients younger than 1 year who had primary posterior capsulectomy, vitrectomy, and in-the-bag hydrophobic acrylic IOL implantation
were reviewed. C59 supplier In bilateral cases, 1 eye was randomly chosen. The need for surgery for visually significant VAO was evaluated
12 months after cataract surgery.
RESULTS: Seventy-two eyes were included. The mean age at cataract surgery was 6.0 months. Seventeen eyes (23.6%) required surgery for VAO a mean of 6.2 +/- 2.9 months postoperatively. The odds for VAO surgery were 3.5 times greater in eyes of female children than in eyes of male children. For AcrySof MA60AC, SA60AT, SN60AT, or SN60WF IOLs, surgery for VAO was required in 25%, 23%, 23%, and 23% of eyes, respectively. The earliest time between cataract and secondary VAO surgery was relatively later (9.0 months) with the SN60WF IOL than with the MA60AC, SA60AT, or SN60AT IOL (4.4, 2.2, and 2.0 months, respectively).
CONCLUSIONS: Nearly selleck products 25% of operated eyes of infants required a secondary surgical procedure for VAO; the rate was higher in eyes of female infants but did not differ between IOL models. The data indicate that surgery for VAO is required later in eyes with an SN60WF IOL than in eyes in which other AcrySof IOLs were used.”
“Thermosetting composites were prepared from soybean-oil-based polyols
(hydroxyl number = 190 mg of KOH/g, [OH]/[NCO] for 2,4-toluene diisocyanate = 0.9) and fillers (10 wt %) from industrial and agricultural residual wastes. www.selleckchem.com/products/brigatinib-ap26113.html Different types of inexpensive residual wastes were used: black rice husk ash, coconut husk ash, calcined retorted oil shale, and retorted oil shale. The fillers were characterized by thermogravimetric analysis and measurements of particle size distribution, specific surface area, and pore size distribution. The fillers were microporous materials with different chemical compositions, with average particle diameters varying from 5.6 to 76.6 mu m, specific surface areas varying between 6 and 165 m(2)/g, and thermal stability at the polyurethane cure temperature (65 degrees C). All composites were characterized by dynamic mechanical analysis, flexural tests, Shore A hardness tests, thermogravimetric analysis, and scanning electron microscopy analysis.
