Description

ProVisc is a high-quality ophthalmic viscoelastic solution designed to support anterior segment procedures in eye surgeries. Manufactured by Alcon, it plays a crucial role in cataract extraction and intraocular lens implantation by maintaining the depth of the anterior chamber and protecting delicate ocular tissues.

Composition

• Sodium Hyaluronate (1%): Provides the viscoelastic properties essential for surgical manipulation.
• Buffer Solution: Composed of sodium chloride and phosphate, ensuring physiological compatibility.

Key Features

• High Molecular Weight: Approximately 2.4 million Daltons, offering a cohesive, gelatin-like consistency.
• Viscosity: Ranges from 39,000 to 200,000 cP, providing stability during surgical procedures.
• Osmolality: 310 mOsm/kg, closely matching physiological conditions.

Packaging

ProVisc is supplied in sterile, disposable glass syringes with volumes ranging from 0.4 mL to 0.85 mL. Each syringe comes with a 22-gauge or 27-gauge cannula, packaged aseptically in blister packs and terminally sterilized for safe use.

Usage Instructions

• Injection: Administered into the anterior chamber to maintain chamber depth and facilitate intraocular tissue manipulation.
• Removal: Should be removed at the end of surgery to prevent postoperative intraocular pressure increase.

Precautions

• Sterility: Must be maintained throughout handling.
• Latex Content: Contains dry natural rubber, which may pose a risk for those with latex sensitivity.
• Intraocular Pressure: Monitoring is recommended postoperatively.

Storage

Store ProVisc upright in a refrigerated environment at 2°–8°C, away from light and freezing conditions. Allow the solution to reach room temperature before use for optimal performance.

Contraindications

Not suitable for individuals with known hypersensitivity to sodium hyaluronate or any other components of the product. Potential side effects include transient intraocular pressure rise, postoperative inflammation, and rare allergic reactions.

ProVisc is a prescription-only medicine, emphasizing the importance of professional handling and administration in ophthalmic surgical settings. Its reliable performance and protective qualities make it an invaluable tool for eye care professionals.
