An Eye for Perfection

From viewing the macula under high magnification to focused viewing of the peripheral retina, high-quality imaging is essential for safe and effective vitreoretinal surgery. But how can vitreoretinal surgeons achieve high-quality optimal imaging in every case? Enter the BIOM HD Disposable Lens and the OCULUS HD Disposable LenZ single-use front lens solutions. The BIOM HD Disposable Lens, included in the BIOM Optic Set, is designed for single-use on the OCULUS BIOM system, whereas the OCULUS HD Disposable LenZ is designed for single-use on the ZEISS RESIGHT® fundus viewing system.  Both provide an extremely wide field of view with high definition clarity in conjunction with the most popular non-contact panoramic viewing systems, making them ideal for all stages of vitreoretinal surgery.

Each lens works on the principles of indirect ophthalmoscopy: a non-contact front lens projects an inverted intermediate image that is viewed through the microscope. The re-inversion of the intermediate image is performed by the SDI® (Stereoscopic Diagonal Inverter) in the BIOM system, or by inverter tubes built into the microscope.

Although both the BIOM HD Disposable Lens and the OCULUS HD Disposable LenZ are designed to provide high-quality wide-field viewing with different imaging systems, they share some common features. Both front lenses share an innovative single-use design based on high-precision, aspheric, injection-molded polymer optics, which allows up to 130° field of view (oro to ora) observation with outstanding resolution and depth of field in fluid-filled eyes or under air – even under high magnification. Available in a convenient, sterile blister pack, each lens is ‘always ready’ for the surgeon to use, with minimized risk of infection and cross-contamination. Moreover, OR efficiency is boosted because there is no sterilization ‘down-time’. 

With the new HD disposable front lenses from OCULUS, every vitreoretinal surgeon can experience the perfect view in every case. To find out more, visit www.oculussurgical.com.

The HD Disposable LenZ in Action

“The new HD Disposable LenZ allows for a wide field of view with a greatly increased depth of focus. This allows visualization of a wide field extending from the macula to the retinal periphery while keeping everything in focus. This is illustrated in Figure 1, where during scleral depression, the peripheral retina as well as the macula are both in focus. During repair of tractional retinal detachment (Figure 2), or during removal of preretinal and subretinal bands or membranes in proliferative vitreoretinopathy (Figures 3 and 4), the depth of field and resolution allow a large area to be in focus at all times whilst maintaining enough detail even under high magnification for the removal of membranes. The resolution offered by the lens is adequate to allow peeling of the internal limiting membrane and epiretinal membrane without the need to switch to a contact lens, which allows for increased efficiency and cost saving in the operating room. The HD Disposable LenZ allows for excellent visualization under air (Figure 5), allowing for efficient laser delivery, which is very valuable towards the end of the case.”
