Abstract Details

Purpose:

OCT-monitoring of the vitrolenticular interface after performing the posterior optic buttonholing (POBH).

Setting:

Multidisciplinary Science and Technology Complex Eye Microsurgery named after Academician S.N.Fyodorov, Federal State Institution, Novosibirsk Branch, Russia.

Methods:

OCT-monitoring (Optovue RTVue-100) was conducted in 24 patients after cataract phacoemulsification with implantation of one-piece acrylic hydrophobic IOLs. Primary posterior capsulorhexis with a diameter of about 3.5 mm was performed after IOL implantation. A small amount of viscoelastic (OVD) was introduced under the posterior capsule (PC) to push the anterior hyaloid membrane (AHM) back. The IOL optics were moved behind the posterior capsule without mechanical stress, using a microhook to retract the edge of capsulorhexis. Dates of OCT-monitoring - 1 day, 3 days, 1 month post-op.

Results:

In all  cases the IOL haptics were in the capsule bag, and the IOL optics were behind the PC. On day 1 retrolental space had a different volume due to OVD. AHM had a clear outline without damage. The AHM profile was determined by the shape of the retrolental space and the condition of the Weiger’s ligament. On day 3 resorption of OVD from retrolental space was observed, AHM was adjoined to the IOL optics. The adhesion of the anterior and posterior leaflets of the capsular bag and the stable position of the IOL were noted in 1 month.

Conclusions:

POBH is a safe PCO prevention technique that allows  to keep the vitreal barrier intact. This technology does not require intraoperative removal of OVD because of self-resorption.
