The Foldable Capsular Vitreous Body (FCVB) is an intraocular implant that encapsulates silicone oil within a flexible capsule to reduce silicone oil-related complications. This protocol describes the surgical implantation of the FCVB via scleral incision for the treatment of complex retinal detachment and ocular trauma.

We present a simple and efficient protocol for the generation of human macrophages. Buffy coats are processed by double density gradient centrifugation and isolated monocytes are then differentiated to macrophages in Teflon-coated cell culture bags. This maximizes macrophage yields and facilitates cell harvesting for subsequent experiments.

We propose a technical modification for capsular reconstruction that utilizes arthroscopic rerouting and fixation of the long head of the biceps tendon to enhance the repair of massive irreparable rotator cuff tears.
FAQs
Zonular fibers connect the capsular bag with the surrounding support system and transmit forces during accommodation. This connection helps maintain the crystalline lens in position while allowing forces to influence its shape. Preserving the relationship between the capsule and zonules therefore supports the lens’s normal positioning and accommodative function.
Residual lens epithelial cells can migrate and proliferate across the posterior capsule after the cloudy lens has been removed. Their growth may produce posterior capsule opacification, which is a common postoperative complication. The process is clinically important because it can affect the capsule that remains behind the implanted intraocular lens.
The anterior and posterior capsules form the continuous membrane surrounding the crystalline lens. Together, they help preserve the lens’s position and shape, while their connection with zonular fibers permits force transmission during accommodation. This organized structure also provides the capsular support retained during cataract surgery.
During cataract surgery, surgeons remove the cloudy crystalline lens while preserving the capsular bag whenever possible. The retained capsule provides a supporting structure for placement and stabilization of an intraocular lens. Preserving this structure also maintains the capsule’s relationship with the zonular fibers and the remaining ocular anatomy.
A capsulorhexis is a controlled opening made in the lens capsule during cataract surgery. Creating this opening allows surgeons to remove the cloudy lens while retaining the surrounding capsular bag. The preserved bag can then accommodate and stabilize an intraocular lens, making the opening an important part of the surgical approach.
Posterior capsule opacification may be treated with a YAG laser capsulotomy. This treatment addresses the opacified posterior capsule after residual lens epithelial cells have migrated and proliferated there. Its clinical role is to manage a common complication that can occur even when the capsular bag has been preserved during cataract surgery.
