Ophthalmic Surgery Scleral Depressor

The scleral depressor system provides globe support to the eye with one or more independent thrusters, or actuators, radially positioned about the eye during surgical procedures. Thrusters may be mechanically operated through various means and an actuator is selectively deployable and selectively retractable by several remote control options. An additional or stand-alone feature includes a fiber optic transcleral illumination system. This automated scleral depressor allows a surgeon to control the position and depth of lateral mobilization of the wall of the eye. This can reduce surgeon frustration while improving visualization, and thereby reducing surgery time, cost and risk to the patient.

Improved Photocoagulation Techniques

Ophthalmic surgery of retina is often complicated by optical and physical barriers. The anatomy and optical properties of the eye may obscure or obstruct the surgeon’s view, particularly of the peripheral retina. The zone behind the iris can also be obstructed from direct view. There is a need for a method and system to allow a surgeon to control pressure to the sclera and improve visualization of the peripheral retina. The scleral depressor can be position and operated with a remote control. The automated scleral depression system can be used in ophthalmic surgery, including the removal of peripheral vitreous and scar tissue, improved laser photocoagulation techniques, and addressing retinal tears or breaks.

BENEFITS OF AN AUTOMATED SCLERAL DEPRESSOR FOR USE DURING OPHTHALMIC PROCEDURES:

  • Allows surgeons to control the position and depth of lateral mobilization of the wall of the eye
  • Increased surgeon control of depression pressure and improved visualization
  • Consistent depression technique relieves dependence on skilled assistance, minimizes risk of complications, reduces surgical time and costs
  • The scleral depressor can be used in the removal of peripheral vitreous and scar tissue, improved laser photocoagulation techniques, and addressing retinal tears or breaks.
