Evaluation of the Vitreolenticular Interface with Intra-Operative OCT.

Abstract. PURPOSE To determine the prevalence of anterior vitreous detachment (AVD) in routine bag-in-the-lens cataract cases and whether we could identify risk factors for its presence. SETTING University Hospital of Antwerp, Belgium. DESIGN Prospective cross sectional study. METHODS Patients having routine bag-in-the-lens cataract surgery were included. Patients with traumatic cataract, prior intra-ocular surgeries, YAG-laser, intravitreal injection or medical conditions that might affect normal ophthalmologic anatomy were excluded. Several parameters were collected from the patients records and their surgical videos/photos/OCT were evaluated. RESULTS 99 Eyes of 99 patients were included. Detectable AVD was observed in 62 eyes (63%). AVD was not present in 37 eyes (37%). The difference in prevalence of AVD between males and females was not statistically significant (P = 0. 55, Pearson Chi Square test). The Mann Whitney U test for axial length was not statistically significant (P = 0. 38). The Mann Whitney U test for age was statistically significant (P < 0.005). A logistic regression model to ascertain the effect of age on the likelihood that patients had AVD did reach statistical significance (χ2(1) = 8.246, P < 0.005). CONCLUSION The prevalence of AVD in a routine cataract population is 63%. We identified age as a risk factor, our model determined that the odds for AVD increase with 5.3% for each year patients age. This data allows for better pre- and postoperative assessment of complications. The bag-in-the-lens, by its mandatory PPCCC, does not increase the risk of postoperative ocular complications in the posterior segment of the eye.
