“…The use of viscous substances has previously been reported in the literature, although reports are limited to injection of the intact canaliculus as an aid in location and intubation, 6,9 whereas our method can also improve visualization of the operative field. Several disadvantages in the traditional method include the inability to inject air, water, or a viscous substance into an intact canaliculus when both systems are injured and the occasional need to use a colored substance with the viscoelastic for improved identification, because the dye tends to paint and cloud target areas as and may enter the eye in cases of concurrent globe injury.…”

“…6,7 Viscoelastic offers several advantages over other methods: it can create a closed system by itself, is innocuous to the body, and can be easily rinsed out on completion of the procedure. 9 As a cost saving alternative, hypromellose can be employed with similar results. The air-injection method is commonly employed by experienced lacrimal surgeons: it is safe, easy, and does not obscure the operative field.…”

“…Instead, we only superficially deploy the viscoelastic in the vicinity of the affected location and into the proximal torn end. The viscoelastic's high viscosity, which makes it tend to linger at the cusp of the cut end of the lumen, 6,9 also makes relocating the proximal canalicular edge easier after the surgeon's attention is drawn away from the torn edge during dilation and passage of an introducer through the lacrimal punctum.…”

“…The technique described here is similar to our recently reported technique that uses a soft side port probe to inject oculentum into the lacrimal sac, with the nasolacrimal duct blocked by the closed tip 5. Given the great viscosity and resistance of the oculentum, it takes a much longer time to fill up the lacrimal sac and achieve reflux.…”

Locating the medial cut end of the severed canaliculus is the most difficult aspect of canalicular repair, especially in patients with more medial laceration, severe oedema, persistent errhysis and a narrow canaliculus. Irrigation is a widely used technique to identify the cut end; however, we found that air injected through the intact canaliculus with a straight needle failed to reflux when the common canaliculus or lacrimal sac was not blocked. We describe a simple, safe and efficient air-injection technique to identify the medial cut edge of a lacerated canaliculus. In this method, we initially submersed the medial canthus under normal saline, then injected filtered air through the intact canaliculus using a side port stainless steel probe with a closed round tip. The tip was designed to block the common canaliculus to form a relatively closed system. The efficiency of this novel air-injection technique was equivalent to the traditional technique but does not require the cooperation of the patient to blow air. Using this technique, the medial cut end was successfully identified by locating the air-bubble exit within minutes in 19 cases of mono-canalicular laceration without any complication.

“…Finding the canalicular cut ends is the first key step during the operation of canalicular reconstruction. A number of techniques including irrigating air, water, colored or viscous agents through the intact canaliculus have been reported to aid in the identification of the canalicular cut ends for repairing canalicular lacerations 2 3 4 . In the clinical practice, we find that any of these methods are defined as difficult procedures or very restricted in patients with a narrow canaliculus, persistent wound bleeding, and especially canalicular scarring in late presenting canalicular laceration.…”

To locate the proximal and distal cut ends of the canaliculus following trauma is the most difficult part of canalicular repair, especially in patients with complex acute canalicular lacerations and late presenting canalicular lacerations. Previously, irrigation and air-injection technique are reported and widely used to locate the cut ends of lacerated canaliculus. However, we have developed a novel technique in which with a 23 Ga fiber optic light pipe is used to identify the cut ends of the canaliculus allowing silicone tube intubation of the lacrimal system. The mean time from initiation of the identification of the cut ends of the canaliculus to insertion of the silicone tube was 5 minutes. In this study, the cut ends were successfully identified by using this novel method in 33 cases of acute and late presenting canalicular laceration for canalicular reconstruction without any complications. This light-guided technique may represent an improvement in the surgical repair of canalicular lacerations.
