Ophthalmic viscosurgical devices (OVDs) are essential to the practice of surgical ophthalmology. Their presence and use in surgical care is ubiquitous, and OVDs played an important role in advancing anterior segment surgery. This Focal Points module provides some historical perspective on the development of OVDs, details their varied and critical roles in surgery, and reviews specifics regarding the molecular structure of these devices. The module also discusses the physical qualities that go along with variations in molecular weight, concentration, and many other parameters. However, the specifics of chemistry of different OVDs are nowhere near as important as understanding the basic differences and varied uses of the different groups of OVDs.

Upon completion of this Focal Points module, you should be able to:

  • Describe the basic differences between cohesive and dispersive ophthalmic viscosurgical devices (OVDs).
  • List three clinical applications of cohesive OVDs.
  • List three clinical applications of dispersive OVDs.
  • Describe the uses of OVDs in ocular surgery beyond the realm of cataract surgery.

Focal Points issues are practical, hands-on discussions of the clinical challenges you face daily. Each issue delivers high-quality, trusted ophthalmic information written and reviewed by leading experts.

Subscribers receive 12 new issues a year, plus access to the Focal Points digital archive.
