Mianyang No.3 People's Hospital Successfully Performs the Third-Generation FCVB Surgery, Preserving Eye-Preserving Hope for Ocular Trauma Patients
Release time: Oct 30,2025
Professor Li Yiping from Mianyang No.3 People's Hospital successfully carried out the hospital's firstthird-generation foldable capsular vitreous body (FCVB)surgery. Professor Li's team implanted the third-generation capsular body into a patient with severe ocular trauma, preserving the patient’s hope. As an innovative new eye-preserving technology, FCVB provides a novel treatment option for patients with fundus diseases such as severe retinal detachment, ocular trauma, and silicone oil-dependent eyes, which is of great significance for saving patients' eyeballs.
Patient Condition Overview
Mr. Z has been working in Tibet all year round. However, a sudden work-related injury drastically altered the course of his life—he suffered an ocular trauma to his left eye. After the accident, he urgently underwent corneal laceration suture surgery locally. Yet, due to the severity of the injury, his left eye condition continued to deteriorate. To seek better treatment, Mr. Z traveled to the Ophthalmology Department of Mianyang No.3 People's Hospital. Following detailed examinations, doctors delivered a devastating list of diagnoses: old retinal detachment of the left eye, choroidal rupture of the left eye, blindness of the left eye, corneal leukoma of the left eye, corneal conjunctivalization of the left eye, aphakia of the left eye, and status post left eyeball rupture repair. More worryingly, his left eye had already developed mild atrophy.
"Doctor, I don't expect to regain my eyesight. I just hope to keep the appearance of my eyeball, otherwise I won't be able to hold my head up when going out..." Faced with the examination results, Mr. Z's request was simple yet urgent. At that time, although his left eye did not require enucleation, mild atrophy had already occurred, and the resulting change in appearance caused him great anxiety. For such cases with signs of atrophy where patients have high demands for ocular appearance, traditional treatment methods often fail to achieve satisfactory results. Just as Mr. Z was in distress, Professor Li's team, after comprehensive evaluation, formulated a foldable capsular vitreous body (FCVB) surgical plan for him.
Hope in Desperation: FCVB Technology Opens a New Path for Eye Preservation
Traditionally, for patients with severe ocular trauma, retinal detachment, and other diseases that progress to the advanced stage requiring enucleation, enucleation combined with orbital implant implantation is usually adopted. But Mr. Z's condition had not reached that critical point; his core demand was to prevent the mild atrophy from worsening and preserve the existing appearance of his eyeball. FCVB technology is precisely tailored to address this problem.
Compared with traditional surgeries, FCVB surgery has distinct advantages.
FCVB is an implant that mimics the structure and function of the human natural vitreous body. Made of special biocompatible materials, it boasts excellent stability and safety. Unlike traditional vitreous substitutes, FCVB can provide long-term support to the eyeball wall, effectively preventing eyeball atrophy while creating a favorable environment for the repair and healing of ocular tissues. FCVB can be individually selected according to the size of the patient's eyeball, delivering a more ideal supporting effect and better maintaining the normal shape of the eyeball.
Targeting Mr. Z's condition, the ophthalmology team of Mianyang No.3 People's Hospital conducted thorough preoperative discussions and preparations, and formulated a detailed surgical plan. During the operation, Professor Li carefully implanted the FCVB into Mr. Z's left eye and accurately completed a series of surgical procedures. The entire operation went smoothly with a good postoperative outcome—the capsular body was in the correct position, and the intraocular pressure of both eyes measured 14 mmHg.
Mr. Z stated that although his left eye vision could not be restored, preserving the appearance of his eyeball was the greatest comfort for him and helped him regain confidence in life.
Professor Li explained that foldable capsular vitreous body (FCVB) surgery is particularly suitable for patients like Mr. Z—those whose condition does not warrant enucleation but have developed mild atrophy, with high requirements for ocular appearance and a desire to halt the progression of atrophy. It is also applicable to patients at high risk of eyeball atrophy due to severe ocular trauma, retinal detachment, vitreoretinopathy, and other diseases, who wish to retain the appearance of their eyeballs. For instance, patients facing the risk of eyeball atrophy or even enucleation due to recurrent retinal detachment that cannot be controlled despite multiple surgeries can consider this technology for treatment.
Of course, FCVB surgery has strict indications and contraindications. Only after a comprehensive evaluation of the patient's specific condition by professional ophthalmologists can it be determined whether the patient is suitable for the surgery. Doctors remind that once an ocular disease such as ocular trauma occurs, patients should promptly seek medical attention at a regular hospital and receive early treatment to maximize the protection of ocular health. If unfortunately facing the risk of eyeball atrophy, do not give up easily. With the continuous advancement of medical technology, cutting-edge technologies like FCVB are bringing hope to more patients.
During the postoperative review, Xiao Z’s left-eye retinal break was completely closed, the symptoms of photopsia and floaters disappeared, and his corrected visual acuity improved. "We didn't expect such a quick recovery. The child only missed a few classes and returned to campus soon. We are truly grateful to the medical team!" the parents said, expressing their deep thanks to the president and Professor Zhou.
Postoperative examinations showed that the retinal break of the right eye was well-apposed on the scleral ridge, with other examination results remaining basically unchanged. The patient and her family expressed great satisfaction with the surgical outcome and extended their gratitude to the medical team.
