Color photographs demonstrate capsular tension ring insertion, IOL placement following posterior tears, sulcus fixation, iris suture fixation, glued IOL techniques, the Yamane double-needle techniques, and the pars plana approach to anterior vitrectomy.
Fifty-four columns positioned in the stands around the stadium will form the inner part of the roof and are connected to an upper and a lower tension ring in the centre of the roof.
Intraoperative use of a capsule tension ring reduces the risk of zonular rupture but is no guarantee against intraocular lens dislocation in the long term.
When adjuvant procedures were performed during surgery (e.g., insertion of capsular tension ring in zonular instability, intracameral injection of epinephrine hydrochloride 0.001% for mydriasis and carbachol 0.01% for miosis, and prophylaxis against increased IOP), these were also recorded.
It has also been shown that the use of the endocapsular tension ring can reduce secondary lens epithelial cell (LEC) proliferation (NISHI et al., 2001).
Capsular tension Ring: As already emphasized, the complications during phacoemulsification surgery are mostly related to zonular weakness and therefore it requires particular attention.
Objective: To evaluate the visual outcome and complications after modified capsular tension ring (CTR) and intraocular lens implantation (IOL) in eyes with subluxated lenses.

Panton says the difference between arches and bridges that use a segment of his tension ring and conventional arches is the inherent strength that comes from the funicular or catenary form that forces stresses towards the centre of each one of the straight lines and circles in the design.
A hexagon spring tension ring ensures roller covers fit securely, and the aluminum alloy construction is highly durable.
Mounted to the side of a heavy wooden box, this simple machine has only about six parts: the frame, axle shaft, sheller wheel, spring, tension ring and crank.
