Key procedures to optimize the sealing process and achieve real-time monitoring of the metal-to-glass seal (MTGS) structure are described in detail. The embedded fiber Bragg grating (FBG) sensor is designed to achieve online monitoring of temperature and high-level residual stress in the MTGS with simultaneous environmental pressure monitoring.

We demonstrate the effect of scleral crosslinking with riboflavin and UVA on an axial elongation rabbit eye. Axial elongation was induced in 13 day-old New Zealand rabbits (male and female) by suturing their right eye eyelids (tarsorrhaphy).

Subretinal injection has been widely applied in preclinical studies of stem cell replacement therapy for age-related macular degeneration. In this visualized article, we describe a less risky, reproducible and precisely modified subretinal injection technique via the trans-scleral approach to deliver cells into rat eyes.

Metacarpal Small Incision for Carpal Tunnel Syndrome

Carpal tunnel decompression with transverse carpal ligament transection is a very successful treatment of carpal tunnel syndrome. The standard long-curved incision technique has become the best treatment for median nerve entrapment decompression. Here we introduce the metacarpal small incision carpal tunnel release (MSICTR) in the treatment of carpal tunnel syndrome (CTS).
FAQs
Closure depends on the incision’s architecture as well as the tissue itself. Once instruments are removed, scleral elasticity helps the layers recoil toward one another, while intraocular pressure supports their apposition from within the eye. When the wound is appropriately configured, these forces can promote a stable, watertight seal without relying on sutures.
These design variables determine how the scleral layers align and how effectively the wound closes after surgery. A carefully balanced configuration must provide sufficient access for the procedure while supporting tissue apposition, watertight closure, astigmatism control, and postoperative healing. Changing one feature can therefore affect both operative handling and the stability of the final wound.
An angled or tunneled pathway creates a layered wound rather than a direct opening through the sclera. That geometry increases the opportunity for tissue surfaces to overlap or meet as instruments are withdrawn. The resulting apposition can help resist leakage and support closure through the combined effects of wound architecture, scleral elasticity, and intraocular pressure.
The procedure begins by fashioning a scleral opening with a planned length, depth, and direction suited to the intended access. Instruments then pass through the angled or tunneled route during the ophthalmic operation. After withdrawal, the incision is allowed to close through tissue apposition and intraocular pressure, with the architecture determining whether a stable seal is achieved.
Small-incision cataract surgery is a major ophthalmic setting for this approach because the incision can provide operative access while avoiding routine suture closure. Eliminating sutures may reduce closure time and limit suture-related inflammation. The design also supports attention to ocular-surface stability, wound sealing, astigmatism control, and healing after the procedure.
The incision must be large and deep enough to permit the required surgical access, yet shaped so the scleral layers return to close contact afterward. Clinicians therefore consider geometry alongside the desired watertight seal and astigmatism control. A suitable balance can shorten closure, reduce suture-related inflammation, and support a stable ocular surface during healing.
