Suction-assisted two-piece cased wide-angle contact lens for vitrectomy
1Department of Ophthalmology University of Florida College of Medicine, Jacksonville, Florida, USA.
Summary
A modified wide-angle contact lens uses plate extensions and a suction device for corneal adhesion. This innovation stabilizes the lens during vitreous surgery, reducing the need for assistant support.
Area of Science:
- Ophthalmology
- Medical Devices
- Surgical Technology
Background:
- Conventional wide-angle contact lenses require manual stabilization.
- Vitreous surgery demands a clear, stable view of the peripheral fundus.
- Existing lens stabilization methods can be cumbersome and require skilled assistance.
Purpose of the Study:
- To modify a two-piece cased wide-angle contact lens for enhanced corneal adhesion and stability.
- To develop a self-stabilizing contact lens system for ophthalmic procedures.
- To improve visualization of the peripheral fundus during vitreous surgery.
Main Methods:
- Modification of a standard wide-angle contact lens with four quadrant plate extensions.
- Integration of a metal housing with an inferior opening for a suction device.
- Attachment of a suction device to the housing for corneal adhesion.
Main Results:
- The modified lens adheres to the cornea via suction, providing stability.
- The system eliminates the need for a skilled assistant to stabilize the lens.
- A stable, well-centered view of the peripheral fundus is achieved.
Conclusions:
- The novel suction-assisted contact lens offers improved stability and ease of use.
- This device facilitates enhanced visualization during vitreous surgery.
- The modified lens design reduces reliance on surgical assistants for lens positioning.
