Kostutusnesteitä

Kostutusnesteitä, commonly known as wetting solutions or contact lens solutions, are sterile liquids designed for the care and maintenance of contact lenses. They play a crucial role in ensuring the comfort, safety, and longevity of contact lens wear. The primary functions of wetting solutions include cleaning, disinfecting, rinsing, and hydrating contact lenses.

Cleaning agents within these solutions help to remove debris, proteins, lipids, and other deposits that accumulate on the lens surface during wear. Disinfection is essential to kill microorganisms such as bacteria and fungi, preventing eye infections. Rinsing removes loosened debris and cleaning or disinfecting agents, preparing the lens for insertion. Hydration is vital for maintaining the lens's moisture content, which is critical for comfortable wear and preventing dryness and irritation of the eye.

There are various types of contact lens solutions available, catering to different lens materials and user needs. Multi-purpose solutions combine several functions into one product, offering convenience. Hydrogen peroxide-based solutions provide a more robust disinfection process but require a neutralization step before lens insertion. Saline solutions are primarily used for rinsing and storing lenses, often in conjunction with other cleaning or disinfecting agents. It is important for contact lens wearers to follow the specific instructions provided by their eye care professional and the solution manufacturer to ensure proper lens hygiene and prevent potential complications.
