Ocular Clip Fixation for Suture-Free Intraocular Lens Repositioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for correcting intraocular lens (IOL) dislocation and subluxation often require multiple entry points and sutures, which are skill-dependent and cumbersome.
Innovation Solution
An ocular clip implant with integrated IOL-engaging and ocular-wall-engaging portions, allowing for single-point insertion and suture-less fixation and repositioning of the IOL using a single instrument.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional methods using multiple entry points and sutures are used to fixate an intraocular lens, then reliable fixation can be achieved, but the procedure becomes cumbersome and skill-dependent
Solution Approach 1:
The patent combines multiple functions (IOL engagement, eye wall anchoring, and fixation) into a single integrated ocular clip implant device. The clip includes an IOL-engaging portion with jaws that grasp the lens and an ocular-wall-engaging portion that anchors to the sclera, eliminating the need for separate sutures and multiple instruments while maintaining reliable fixation
Solution Approach 2:
The ocular clip implant serves multiple functions simultaneously: it engages the IOL through its jaws, anchors to the eye wall via its ocular-wall-engaging portion, and provides stable fixation. This multi-functional design simplifies the procedure by replacing multiple specialized tools with a single versatile device
2Ease of operation
If multiple entry points are used to access the IOL for repositioning, then adequate access can be obtained, but the number of incisions and tools required increases
Solution Approach 1:
The patent combines the functions of multiple instruments (forceps for grasping and anchoring device for fixation) into a single ocular clip implant that can be delivered through one entry point. The clip's integrated design allows it to perform both IOL engagement and eye wall anchoring through the same surgical access
3Reliability
If sutures are used to secure the IOL in position, then stable fixation is achieved, but the procedure becomes more time-consuming and skill-dependent
Solution Approach 1:
The patent extracts and eliminates the suture component from the fixation procedure. Instead of using separate sutures to secure the IOL, the ocular clip implant provides direct mechanical anchoring through its ocular-wall-engaging portion, removing the time-consuming suture tying and securing steps while maintaining stable fixation

AI summary
An ocular clip implant (22) used for securing an intraocular lens (IOL) (62) in an eye of a patient is provided which includes an IOL-engaging portion (26) disposed at a first end of the ocular clip implant (22). The IOL-engaging portion (26) is configured to grasp a portion of the IOL (62). An ocular-wall-engaging portion (28) is integrated with and disposed at a second end of the ocular clip implant (22). The ocular-wall-engaging portion (28) includes an anchor (29) transitionable from a first, straightened configuration to a second, non- straightened configuration to anchor the ocular clip implant (22) to a wall of the eye in order to secure the IOL (62) to the eye. Other embodiments are also described.
