Anterior capsule tear during cataract surgery can require additional surgical procedures and may lead to worse refractive outcomes and permanent vision loss, according to a study.
The retrospective interventional controlled case series consisted of 239 study eyes that experienced an intraoperative anterior capsule tear and 212 consecutive uncomplicated phacoemulsification procedures that served as the control group.
In the study group, the observed rate of tear extension to the posterior capsule was 24%, with vitreous loss in 15.9% of eyes and lens material drop in 4.6% of eyes.
Overall refractive outcomes in the study group were poor, with 78.1% of eyes within 1 D of the intended postoperative refraction and only 42.4% within 0.5 D. These outcomes were significantly worse compared with the control group (P < .0001).
Visual acuity of at least logMAR 0.3 was observed in 77% of eyes in the study group compared with more than 93.9% in the control group; the difference was statistically significant (P < .0001). Twelve eyes in the study group lost at least one line of visual acuity.
More than 11% of eyes in the study group underwent unplanned secondary surgeries.
The authors recommended implanting a single-piece IOL in the capsular bag vs. a multi-piece IOL to achieve a final refraction close to the target. – by Kristie L. Kahl
