Description

Angle separation device for ophthalmic surgery

Technical Field

The utility model relates to the technical field of ophthalmic surgical instruments, in particular to a chamber angle separation device in ophthalmic surgery.

Background Art

Glaucoma is a common ophthalmological disease characterized by pathological increase in intraocular pressure, which leads to irreversible damage to the optic nerve and progressive decline in visual function. The prevalence of primary angle-closure glaucoma in my country is 3.05% among people over 40 years old, and the blindness rate is as high as 38%. PACG patients have an anatomical structure with short axial length, shallow anterior chamber, and narrow angle. The lens enlarges and thickens with age, playing an important role in the onset of PACG. It can cause the peripheral iris to shift forward, the angle to narrow, or even close acutely, leading to an acute attack of PACG.

Age-related cataracts are a common cause of lens volume and thickness increase, so PACG patients often have cataracts. The treatment of this type of patients is mainly surgical. The main surgical method in the early stage was simple phacoemulsification cataract extraction and intraocular lens implantation, which can simultaneously solve cataracts and relieve pupillary block. However, long-term follow-up studies have found that patients still have adhesions in the anterior chamber angle after surgery. Therefore, in recent years, phacoemulsification cataract extraction and intraocular lens implantation combined with intraoperative blunt goniolysis to treat PACG has been widely carried out in clinical practice. Blunt goniolysis directly opens the narrow angle of adhesion and restarts the aqueous humor filtration function of the trabecular meshwork. It can effectively treat patients with narrow anterior chamber angle and cataracts, as well as patients with PACG and cataracts with an angle adhesion closure range of ≤180°. Medical institutions with conditions can use intraoperative gonioscopes or endoscopes to bluntly separate the closed anterior chamber angle under direct vision, which is more accurate, reliable and precise.

In the past, blunt goniolysis was performed with a viscoelastic needle. The viscoelastic was injected while the iris root was gently pressed with the needle to bluntly separate the entire circumference of the anterior chamber angle to loosen the angular adhesion. However, for patients with tight angular adhesion, the iris root and the angular adhesion are mostly fibrotic, and it is difficult to perform blunt separation using only viscoelastics, and instruments are required for peeling. Previous goniolysis devices were relatively sharp. Although the viscoelastic needle is blunt, the contact area is small, which can easily cause fiber breakage, iris depigmentation, iris root bleeding and detachment. If the cleaning is not timely or there is bleeding after surgery, it may lead to recurrence or aggravation of angular adhesion after surgery, aggravate postoperative uveitis reaction, and even cause postoperative high intraocular pressure, resulting in iatrogenic angular tearing, which reduces the success rate of surgery and patient satisfaction after surgery. Therefore, we have launched a new goniolysis device for ophthalmic surgery.
