Trophic Composition for Corneal Epithelium Regeneration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ophthalmic and ophthalmologic compositions fail to effectively improve the viability, growth, and differentiation of corneal epithelial cells, particularly under stress conditions, and do not maintain the integrity and equilibrium of the corneal epithelium without using cellular growth factors, biological extracts, or therapeutic active principles.
Innovation Solution
A trophic composition in an aqueous medium comprising a complex nutritive base with essential amino acids, vitamins, trace elements, and metallic salts, along with a collagenase inhibitor and a promoter of neocollagen synthesis, formulated to maintain a specific pH and osmolarity, which includes hyaluronic acid and a preservative like polyhexamethylene biguanide, to promote corneal health and regeneration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cellular growth factors, biological extracts, or therapeutic active principles are used in ophthalmic compositions, then the viability and growth of corneal epithelial cells is improved, but the composition becomes more complex and may introduce harmful factors or uncertainty in composition
Solution Approach 1:
The patent removes cellular growth factors, biological extracts, and therapeutic active principles from the composition, retaining only the essential nutritive base components (amino acids, vitamins, trace elements, metallic salts) that are naturally present in tear fluid. This extraction of problematic elements resolves the contradiction by eliminating composition complexity and uncertainty while preserving the core nutritive function.
Solution Approach 2:
The patent optimizes the concentrations of amino acids, vitamins, trace elements, and metallic salts to match physiological levels found in natural tear fluid. By adjusting these parameters to physiological norms rather than using supraphysiological growth factors, the composition achieves reliable cellular support without the complexity and potential harm of added biological extracts.
2Device complexity
If a complex nutritive base without growth factors is used, then the composition is simpler and safer, but the ability to promote cell growth and differentiation under stress conditions is reduced
Solution Approach 1:
The composition enables corneal epithelial cells to utilize their own endogenous growth factors and regulatory mechanisms. By providing a clean, simplified nutritive base without exogenous growth factors, the cells are empowered to regulate their own growth and differentiation responses according to their physiological needs and stress conditions, achieving productivity through self-regulation rather than external stimulation.
Solution Approach 2:
The patent carefully balances the concentrations of amino acids (particularly glutamine, arginine, and cysteine), vitamins, and trace elements to create optimal nutritional conditions that support natural cell growth rates. The parameter optimization ensures that cells receive adequate nutrition for growth without the need for growth factor stimulation, maintaining productivity through physiological nutrition alone.
3Reliability
If biological extracts are included in the composition, then cellular nutrition is enhanced, but the composition becomes less stable and more variable in its effects
Solution Approach 1:
The patent removes biological extracts from the composition entirely, replacing them with chemically defined amino acids, vitamins, trace elements, and metallic salts. This extraction eliminates the variability and instability inherent in biological extracts while maintaining nutritional efficacy through precisely controlled concentrations of individual nutritive components.
Solution Approach 2:
The composition creates a stable composite of chemically defined nutrients that work synergistically together. By combining amino acids, vitamins, trace elements, and metallic salts in optimized ratios that mimic natural tear fluid, the patent achieves reliable nutritional efficacy through a stable, homogeneous composition without the batch-to-batch variability of biological extracts.
4Adaptability or versatility
If the composition is designed for broad ophthalmic use, then versatility is improved, but the formulation becomes more complex to satisfy multiple requirements
Solution Approach 1:
The patent creates a universal nutritive base that addresses multiple ophthalmic needs through a single simplified formulation. The composition of amino acids, vitamins, trace elements, and metallic salts provides comprehensive nutritional support for corneal epithelial cells, making it applicable to various conditions (dry eye, corneal ulcers, post-surgical care, contact lens comfort) without requiring different formulations for different applications.
Solution Approach 2:
The patent optimizes the formulation parameters to achieve physiological compatibility across different ophthalmic applications. By adjusting pH, osmolarity, and nutrient concentrations to match natural tear fluid characteristics, the composition becomes universally applicable to various ocular surfaces and conditions without requiring complex customization for each specific use case.

AI summary
The invention relates to a trophic composition in an aqueous medium comprising a complex nutritive base. The aforementioned base comprises, as a minimum, multiple amino acids, vitamins, trace elements and metallic salts, and is free of any cell growth factors, any biological extracts of animal or cell origin and any active therapeutic agents. The inventive composition is characterised in that, in addition to the complex nutritive base, it also comprises an inhibitor of the collagenases of corneal epithelium in humans or animals. The composition is further characterised in that it is formulated with the complex nutritive base in order to establish a pH of between 7.3 and 7.5 and an osmolarity of between 300 and 350 m Osm.
