Haptic Optic Management With Edge Rollers for Small-Incision IOL Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ophthalmic surgery techniques face challenges with smaller incision sizes for intraocular lens (IOL) insertion, leading to issues with tool size and functionality, particularly in reducing post-operation healing time and ensuring efficient delivery of the IOL into the eye.
Innovation Solution
A haptic optic management system (HOMS) is introduced, featuring a housing with a bore and cavity, arms, and edge rollers, which folds and aligns the IOL for delivery through a nozzle using a drive system, allowing for precise insertion even with small incisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the incision size is reduced to reduce post-operation healing time, then healing time is improved, but the size and functionality of the insertion tool deteriorates
Solution Approach 1:
The IOL is divided into two separate components: a folded optic portion and haptic extensions. The optic is folded into a compact configuration for insertion through small incisions, while the haptics remain separate to engage with the capsular bag. This segmentation allows the insertion tool to be smaller while still achieving proper IOL implantation.
Solution Approach 2:
The IOL optic is folded into a nested configuration where portions of the optic are placed over other portions, creating a compact structure that fits within small incisions. The folded optic is then inserted through the small incision site into the eye.
2Loss of time
If the incision size is reduced to reduce post-operation healing time, then healing time is improved, but the functionality of the insertion tool deteriorates
Solution Approach 1:
The IOL optic is pre-folded into the correct configuration before insertion through the small incision. The folding process is performed in advance using the haptic optic management system, so that when the compact folded optic is inserted through the small incision, it is already in the proper shape for implantation, eliminating the need for complex manipulation during insertion.
Solution Approach 2:
The haptic optic management system acts as an intermediary device that manages the IOL optic folding and positioning before insertion. This intermediary system allows the insertion tool to be simplified for small incisions while still achieving proper IOL implantation through the pre-folded configuration.
3Length of moving object
If the IOL is folded into a compact configuration for small incisions, then the insertion tool size is reduced, but the alignment precision of the IOL deteriorates
Solution Approach 1:
The IOL folding configuration is designed to be dynamic rather than static. The folded optic maintains a compact form for insertion but is designed to unfold and align properly once positioned in the eye. The haptic extensions provide dynamic adjustment capability to ensure proper alignment of the optic with the capsular bag after insertion through small incisions.
Solution Approach 2:
The mechanical folding and alignment process is replaced by a haptic optic management system that uses controlled folding mechanisms and haptic extensions to achieve proper IOL alignment. This substitution allows for precise alignment control even when the insertion tool itself is minimized for small incisions.
