4.Objective To investigate the etiology, manifestations and treatment of glaucoma secondary to chalasia and/or dialysis of the lens zonular fiber.
5.Methods We studied 23 cases which suffered glaucoma secondary to chalasia and/or dialysis of the lens zonular fiber and received lens extraction retrospectively.
6.Can partially rotate for tight shutoff. In the fully open position, it rests against a stop.
7.Phaco emulsification cataract extraction or phaco emulsification cataract extraction combined with anterior vitrectomy as well as posterior chamber lenses implanted into the capsular bag or transsclerally sutured were performed in all cases according to the different instances of zonular fiber.
8.The non-uniformity of stress and short-term relaxation in wires of curvedtendon are observed, the ultimate elongation and loading capacity as well asbutton-head anchorage in the curved prestressing tendons are investigated incomparison with those of the straight tendon tensioning tests, it is believedthat the strength behaviour of the former is just as reliable as that of thelatter.
