been inconclusive. While some studies support
the protective effects of CTRs, others suggest
CTRs may lead to earlier and more frequent ITB
dislocations.

Therefore, Mayer-Xanthaki et
al. sought to further characterize the impact of
CTR implantation on the development of ITB
dislocations.
Methods
This investigation was conducted as a single-
center, retrospective cohort study based on
medical records at the Medical University of
Graz, a tertiary care center in Austria. These
data had previously been utilized by some
of the authors in a study on the relationship
between IOL design and ITB dislocation.

The
study included patients who received cata-
ract surgery, including extracapsular cata-
ract extraction and phacoemulsification with
implantation of a posterior chamber IOL, from
July 1996 to July 2017, with identification of

Review of "Capsular tension ring
as protective measure against
in-the-bag dislocations after
cataract surgery"
I
n-the-bag (ITB) dislocations of an intra-
ocular lens (IOL) after cataract surgery is
a rare complication that can detract from
the many benefits of cataract surgery. ITB
dislocation refers specifically to dislocation
of the entire capsule-IOL complex, usually a
late (months to years) complication that occurs
as a result of zonular weakness induced by
anterior capsule contraction.
1,2
Capsular ten-
sion rings (CTRs) have been shown to stabilize
the capsule intraoperatively in the setting of
zonular dehiscence or instability.

Logically,
CTR implantation has been hypothesized as a
potential method to reduce the incidence of ITB
dislocations. Previous research, however, has
