Solution Overview

Problem

Current treatments for meibomian gland dysfunction (MGD) are limited to painful physical methods for removing keratinized obstructions, with no pharmacological agents available to address this issue effectively.

Innovation Solution

Topical administration of compositions containing keratolytic agents such as benzoyl peroxide, salicylic acid, or selenium disulfide in ophthalmically-acceptable carriers to the eyelid margin, allowing for the passage of keratinized obstructions and preventing further blockages in the meibomian gland.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If physical removal methods are used to remove keratinized obstruction of the meibomian gland, then the obstruction is removed, but the patient experiences significant pain

Engineering Contradiction:
Improveeffectiveness of obstruction removalVSAvoidpatient pain
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces mechanical/physical removal methods with a chemical/pharmacological approach using keratolytic agents. The composition topically applied to the eyelid margin uses keratolytic agents to chemically break down and remove keratinized obstructions, substituting the mechanical force-based physical removal with a chemical dissolution mechanism that is less painful for the patient

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a keratolytic agent as an intermediary substance between the treatment goal and the patient. This agent acts as a mediator that facilitates obstruction removal through chemical action rather than direct mechanical intervention, reducing the harmful effect of pain while achieving the therapeutic objective

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If physical removal methods are used for MGD treatment, then keratinized obstruction is removed, but frequent office visits are required

Engineering Contradiction:
Improveobstruction removalVSAvoidfrequency of office visits
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent enables self-service treatment by providing a topical composition that patients can apply at home to their own eyelid margins. The keratolytic agents in the composition continue to work on keratinized obstructions over time, allowing patients to maintain treatment without requiring frequent office visits for professional intervention

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent uses continuous partial action through repeated topical applications of the keratolytic composition. Rather than requiring single intensive office-based procedures, the treatment achieves obstruction removal through multiple smaller applications over time, reducing the need for frequent office visits while maintaining effective treatment

Inventive Principle:
Principle #16Partial or excessive action

3Adaptability or versatility

If no pharmacological agents are available for MGD, then treatment options are limited, but physical methods cause ocular irritation

Engineering Contradiction:
Improvetreatment optionsVSAvoidocular irritation
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the fundamental parameter of treatment modality from physical/mechanical to chemical/pharmacological. By formulating keratolytic agents in an ophthalmically-acceptable carrier with specific concentrations (e.g., selenium disulfide 0.1-10%, salicylic acid 0.1-10%), the treatment achieves versatility in addressing MGD while controlling ocular irritation through optimized chemical parameters and formulation

Inventive Principle:
Principle #35Parameter changes
