Novel Ophthalmic Instrument Designs for Cataract Surgery
University of California System: University of California, San Francisco
posted on 11/24/2011
Precise positioning of the intraocular lens during cataract surgery is critical for optimal performance. Currently, cataract surgery is performed using viscoelastic material to safely position the synthetic intraocular lens (IOL). This viscoelastic material must be removed from the eye prior to the end of surgery to prevent clogging of the drainage channels of the eye and increased intraocular pressure. However, during this removal, the IOL often shifts position, requiring imprecise nudging of the IOL with available tools, such as blunt-tipped cannulas, or the re-injection/re-evacuation of viscoelastic for further positioning. What is needed is a device specifically designed for accurate lens positioning and a method that does not require additional viscoelastic, thus saving time and reducing the risk of retained viscoelastic material in the eye.
Detailed Description
An investigator in the Ophthalmology Department at UCSF has specifically designed a surgical instrument that allows for more effective and precise IOL positioning by maintaining anterior chamber depth without the use of additional viscoelastic material. The investigator has developed multiple instrument designs that can be used for IOL positioning after removal of viscoelastic.
File Number: 22121
Disease: Ophthalmology and Optometry
Other Information:
The inventor welcomes the opportunity to collaborate with industry partners to develop and test prototypes of the instrument.Advantages and Suggested Uses
- Designed for use during final IOL positioning, for accuracy in centration and alignment.
- Maintains anterior chamber depth without the use of viscoelastic material.
- Eliminates need for re-injection/re-evacuation of viscoelastic: saves surgical time and reduces risk of retained viscoelastic material.
- Low profile to minimize wound gape and distortion of view into anterior chamber
- Multiple instrument designs developed.
- Can be manufactured out of materials that can be re-used/sterilized or as a consumable/disposable.
