“…When a CTR is placed prior to cortical clean-up, the CTR can entrap cortical material between the CTR and capsular equator, rendering it challenging to remove all cortex [9]. To address this challenge, the Henderson CTR (HCTR, Morcher GmbH) was created that has 8 equally spaced 0.15 mm indentations creating a sinusoidal shape.…”

Purpose of reviewThis review will focus on identifying causes of zonulopathy during cataract surgery and discuss various modalities for treatment. Recent findingsThere are multiple different options for capsular bag support in the setting of zonulopathy, including capsular or iris hooks, capsular tension rings as well as capsular tension segments (CTS). Surgical techniques on how to insert these devices are many and can be customized based upon the surgeon's preference and the patient's eye anatomy.

“…Early CTR implantation following capsulorhexis and hydrodissection is popular because it supports the area of zonular weakness during cataract extraction. 6 However, it is difficult to remove the residual cortex trapped in the space between the CTR loop and the capsular equator. To combat this difficulty, modified CTR, which creates the space between CTR and the capsular bag equator, was invented.…”

Capsular tension ring (CTR) realizes safe cataract surgery. However, residual cortex removal becomes difficult with CTR. Originally, the flushing technique was developed for intracameral antibiotic administration. Using this technique with larger amounts of solution enables surgeons to 1) deliver antibiotics to the anterior chamber and area behind the intraocular lens, resulting in stable, scheduled antibiotic concentration and 2) entirely irrigate and displace the area, leading to the effective cleansing of residual substances and bacterial pollution. When performing the flushing technique, the residual cortex and debris that were not eliminated by ordinary irrigation and aspiration can be pushed out to the anterior chamber. Applying flushing technique to CTR cases, the residual cortex and debris trapped between the CTR loop and capsular equator is lifted into the anterior chamber and easily removed. If the capsular bag is polluted by bacteria, it may also be lifted to the anterior chamber.
