“…12,13 Cadaver studies show that IOLs with a 12.0 mm haptic diameter distort the capsular bag less than larger IOLs and are more stable than smaller IOLs. 13 Results in previous studies suggest that a 2-haptic IOL with a haptic diameter smaller than 12.5 mm is not stable when implanted in a large capsular bag. 14 In contrast, our results indicate that the 3-haptic IOL we evaluated (haptic diameter 10.35 mm) is stable in a large capsular bag; to date, there has been only 1 case of IOL decentration in our highly myopic population.…”

Since the first introduction of the capsular ring in 1991, the open capsular tension ring proved to be efficient in various indications and applications: e.g. in zonular dialysis or or weakness, with integrated tinted sector shield in sector or aniridia, to facilitate primary posterior capsulorhexis, for prophylaxis of intraocular lens decentration or as an intraocular measuring gauge. Nishi modified this capsular tension ring mainly by increasing the width to 0.7 mm and created a rectangular edge, thus facilitating the creation of a sharp, discontinuous bend in the equatorial capsule. This band-shaped, sharp-edged capsule-bending ring prevented the anterior capsule from coming into contact with the posterior capsule. This is most likely due to the 0.7 mm width of the capsule-bending ring, which significantly prevented anterior capsule opacification, which commonly occurs within one month postoperatively. Posterior capsule opacification seems to be reduced as well, but final evaluation is needed for a longer period of time. The capsular tension ring as well as the capsular bending ring enlarge our surgical options in modern cataract surgery. Both can be considered as a useful instrument and promising innovation.
