Professor Zhu Jundong from Changsha Aier Eye Hospital Successfully Performed the Third-Generation FCVB Surgery

Recently, Changsha Aier Eye Hospital received a patient with extremely severe ocular trauma. Professor Zhu Jundong successfully performed the third-generation foldable capsular vitreous body (FCVB) implantation surgery for him, saving his eyeball and preserving hope!

Condition Overview

Mr. Z, a 59-year-old local in Hunan, had an accident on August 25. A small iron piece hit his right eye, causing immediate blindness in that eye. He was sent to Changsha Aier Eye Hospital for treatment 4 hours later. After examination, Professor Zhu Jundong diagnosed him with "right eye intraocular foreign body, right eye traumatic hyphema, right eye aphakia, right eye vitreous hemorrhage, right eye postoperative corneal-scleral laceration, and right eye endophthalmitis". Traditional treatment for ocular trauma involves vitrectomy combined with silicone oil tamponade. However, Mr. Z's injury was so severe that his eyeball was at risk of being enucleated. To save the eyeball, after full communication with the patient, Professor Zhu decided to perform "right eye posterior approach vitrectomy + right eye intraocular foreign body removal + right eye foldable capsular vitreous body (FCVB) implantation".

On August 30, with the full cooperation of Professor Zhu's team, a 25mm long and thin iron piece was first removed. Then, scleral puncture preparation, central vitrectomy, and peripheral vitrectomy were performed. Finally, the third-generation FCVB was successfully implanted.

The removed iron piece On the second day after the surgery, Mr. Z's examination showed a deep anterior chamber, intraocular pressure of 12, and the capsular position was correct. He was satisfied with the postoperative effect and was very grateful to Professor Zhu for saving his eyeball.

Foldable Capsular Vitreous Body (FCVB)

The foldable capsular vitreous body (FCVB) is the first internationally innovative product that simulates the natural vitreous body of the human eye. It consists of a capsule, a drainage tube, a drainage valve, and a fixation loop. The capsule is precisely simulated based on the parameters of the human vitreous cavity through computer technology, with a special crystal surface plane design. The raw material is a medical silicone polymer imported with US FDA approval. During the surgery, the capsule is folded and implanted into the vitreous cavity, and silicone oil is injected through the drainage valve. The capsule is fixed in the eye through double loops of the fixation loop and suture of the drainage tube, isolating the damage of silicone oil to the ciliary body. The capsule can retain the posterior chamber space, allowing the ciliary body to slowly recover its function, saving the disabled ciliary body and maintaining intraocular pressure; it avoids silicone oil emulsification and displacement; and fully supports the retina and maintains the shape of the eyeball.

Third-Generation FCVB

1. The drainage tube and drainage valve are reduced and folded back into the eyeball;
2. 2. A fixation loop structure is added to fix the capsule, making it more stable in the eye;
3. 3. The diameter of the capsule and the optical zone is fine-tuned, and a new AV-10PX model is added to make the product more suitable for atrophic eyeballs;
4. 4. Implantation through the corneal limbus incision is safer and more convenient.
