Abstract Details

Purpose:

To report the changes in vitreolenticular and vitreoretinal interface after complicated and uncomplicated cataract surgery

Setting:

S. Fyodorov Eye Microsurgery State Institution, Moscow, Russia

Methods:

18 patients (18 eyes) undergone cataract surgery. Clinical characteristics and surgical video were documented. The optical coherence tomography (OCT) was performed with spectral domain RTVue-100 OCT (Optovue, Inc., Fremont, CA) with cornea line scan mode and vitreoretinal interface was evaluated at the retina map mode – preoperatively and, -one week of follow-up (FU). The sample size will be increased by the date of the study presentation and FU will be extended to one month.

Results:

One case were complicated by intraoperative posterior capsule (PC) rupture, who was safely converted into a posterior capsulorhexis resulted in anterior hyaloid (AH) adhered to the IOL and resulted in PVD (?). Postoperatively, Berger`s space was visualized in 11 eyes. In the 4 cases where the Berger`s space was present the posterior vitreous detachment (PVD) was absent (emmetropic eyes), whether the 3 other myopic eyes were with no Berger`s space, but adherence of the PC to the IOL and the PVD was identified. In one emmetropic eye, the only one that had weekly OCT exam since the cataract surgery, the size of the Berger`s space was gradually changed during that period of time with the extension of the PVD.

Conclusions:

The OCT confirms the dynamic changes of vitreolenticular interface that is more prone to be absent in the cases of PC rupture, that may confirm the positive pressure of the aqueous humor directing the PC anteriorly in postoperative period. In case of AH damage, that theory would support the migration of the vitreous composites anteriorly increasing the risk of intraocular inflammation and vitreous traction syndrome. The PVD was associated with the collapse of the vitreolenticular interspace as well as the PC movement anteriorly to the posterior surface of the IOL.
