It is general practice to dilate patients for a BIO exam, in cases where dilation is not possible, or patients inherently have small pupils (neonates or geriatrics) higher power lenses are appropriate. Whether you work in a hospital or research facility, are selling or using our eyewear, are an individual or a corporation, our laser engraving can have a huge impact on the quality and usefulness of your eyewear. As a general rule of thumb, as the dioptric power of the lens increases, the field of view increases, magnification decreases and the working distance decreases. The distance at which the lens needs to be held in front of the patient’s eye varies depending on the power of the lens. As the names suggests, the image formed is indirect in nature meaning it is inverted and reversed. The condensing lenses used for BIO examination have a higher magnification and lower field of view profile when compared to slit lamp biomicroscopy lenses. The patient can be in a supine position or sat with the head tilted at a comfortable angle. This technique has a greater scope for dynamic examination due to the mobility offered by the oculars not being fixed to a table top. Please allow 6 weeks for delivery for lenses with engravings.Binocular Indirect Ophthalmoscopy (BIO) is a diagnostic procedure by which a practitioner uses a condensing lens and a head mounted ocular system to look at the retinal structures. The optical design of the H-R series provides bright, high resolution views that are distortion free even at the periphery.Ĭomes with single lens case. ![]() Despite the smaller lens size, the contact surface is designed carefully to provide optimum stability on the patient’s cornea while ensuring patient comfort. The small lens body with an 24.8 mm lens ring and 21.7 mm lens height makes it a nimble lens, leaving the doctor ample space between the patient’s eye and the laser for focusing and manipulation. This lens is perfect for diagnosis and treatment of peripheral and far peripheral retinal defects such as peripheral retinal tears and retinal detachments. A part of our H-R series of laser lenses, the H-R wide field provides the widest field of view spanning the retinal from the posterior pole all the way out to the ora serrata. ![]()
