Fluorescein Filter

A simple clip-on mechanism enables a low cost upgrade to many common slip lamps on market

Our Yellow Filter can be used for many conditions including early detection of micro punctate corneal staining caused by contact lens, solution interaction, early detection of the correlation between patient symptoms and signs of dry eye syndrome, and better visualization of RGP (Rigid Gas-Permeable) fluorescein patterns.

Common uses include the viewing of:

Corneal abrasions
Trauma
Foreign bodies/ debris
Tear breakup
Partial blinking
Contact lens fitting/ irritation

Features

Enhanced color formula

Provides superior fluorescein viewing

Raised dimples

Keep lens away from surfaces and reduce scratches

Finger holds

Triangular holds allowing easy handing while cliping-on

Round panel

Circular shaped large lens area maximises visual and achieves unobstructed viewing

Arms

Flexible arms help with reliable and simple attachment to slip lamps

Tear film break up in action

Fast changes in tear film composition give rise to darker regions indicating the possibility of dry eye disease which become apparent with the fluorescein filter

From Ophthalmologist：

It is great to see a robust, regulatory approved yellow filter based on our research, become available for all those slit lamp biomicroscopes that don’t have one built in. A yellow filter is vital for optimised viewing of fluorescein on the ocular surface and its spectral transmission needs to be carefully selected. In addition, the AVS filter clips in place, making examination of the eye easier”

"The yellow filter is an amazing asset to improve the fluorescein visualisation of the cornea epithelial surface for subtle changes that may be easily missed otherwise. It is also a great teaching tool for junior ophthalmology trainees, optometrists and nurse practitioners who are starting to learn how to look for these changes as it clearly highlight them even with minimal fluorescein staining"
