Bowman's probe is a thin, metal instrument used in eye care to examine or open blocked tear ducts. It has a smooth, rounded tip that allows doctors to gently pass it through the tear drainage system without damaging delicate tissues. The tool helps confirm the location and severity of a blockage. It is commonly used during procedures to treat conditions like nasolacrimal duct obstruction.

Bowman's probe is also used during procedures that involve dilation or irrigation of the tear ducts. In infants, it is often used to clear congenital tear duct blockages safely.
Bowman's probe resembles a slender stainless-steel rod with rounded tips on both ends. Each end has a slightly different diameter, allowing doctors to select the size that fits the patient's tear duct. The smooth surface minimizes trauma during insertion. The tool is available in multiple sizes for use in both adults and children.
It is typically used as follows:
Bowman's probe is used to manage blockages in the lacrimal drainage system, such as nasolacrimal duct obstruction. It is also applied in cases of chronic tearing or infection caused by poor tear drainage. Early use in infants helps restore normal tear flow and prevent recurring eye discharge. In adults, it may be part of minor surgical procedures to maintain duct patency.
If you or your child are undergoing tear duct treatment and symptoms persist, a follow-up visit may be needed. Bowman's probe is often used to open blocked ducts, and some cases require repeat evaluation. Early care helps restore proper tear drainage. Any new swelling or discharge should be checked promptly. Regular monitoring supports comfortable eye function.
Most people feel pressure rather than pain because numbing drops are placed first. A brief stinging sensation can happen when the drops go in. After the procedure, the inner corner of the eye can feel mildly sore for a short time. If pain feels strong or keeps worsening, contact the clinic.
The probing portion is often quick once the area is numb. The full visit can take longer because it can include prep, irrigation, and post-procedure checks. In children, the timing depends on anesthesia and recovery steps. Your doctor can explain what the timeline looks like for your case.
Mild bleeding from the punctum or light swelling can happen and often settles quickly. Infection is uncommon, but increasing redness, thick discharge, or worsening tenderness can be warning signs. A false passage can occur if the anatomy is tight or scarred, which is one reason gentle technique matters. Follow the aftercare plan to lower irritation.
Doctors often recommend antibiotic drops or ointment for a short period. Light tearing or watery discharge can happen as the duct settles. Avoid rubbing the inner corner of the eye and keep the area clean. Return for follow-up if tearing does not improve or swelling appears.
