Corneal stromal overgrowth (retrocorneal membrane, fibrous overgrowth) is one of the common complications of penetrating keratoplasty (Kurz and D'Amico, I968). As a postoperative complication of cataract extraction leading to enucleation, however, it is less well recognized. Few case reports exist in the literature, and Duke-Elder (i969) fails to cite stromal overgrowth as a complication ofcata...

The pre- and postoperative refraction results are reported in 99 patients receiving an anterior chamber lens of standard 19.0 D power after intracapsular cataract extraction. The mean refraction after the operation was -0.76 D, SD 2.13. Apart from eight patients with suspected lenticular myopia, 5% of the patients ended up with a refraction that differed more than +/- 5D from the preoperative v...

A low-melting solid is used as organic solvent for liquid-liquid extraction at elevated temperatures followed by solidification and decantation of the aqueous phase.

By administering fluorescein intravenously to 95 patients we calculated the ratio of fluorescein concentration in the vitreous at the time of its peak level compared with the estimated unbound concentration of fluorescein in the plasma at the same time. We studied 12 normal phakic and 83 aphakic eye approximately two months, one year, and more than two years after cataract extraction. All the e...

Various materials are used in modern dental and maxillofacial surgery for bone tissue substitution and reconstruction. All osteoplastic materials can be divided into four groups by origin: autogenic, allogenic, xenogenic and synthetic. Synthetic resorbable materials were intended as an inexpensive substitute for natural bone. Synthetic graft materials include various types of ceramics: tricalci...
