BSS Plus Intraocular Irrigating Solution

BSS Plus Intraocular Irrigating Solution Overview

Surgical procedures involving sensitive delicate ocular tissues require specialized fluid environments to preserve cellular integrity and tissue function. The combination of Calcium Chloride, Dextrose, Glutathione Disulfide, Magnesium Chloride, Potassium Chloride, Sodium Bicarbonate, Sodium Chloride, and Sodium Phosphate widely known by the brand name BSS Plus is an advanced, balanced intraocular irrigating solution. Used predominantly in ophthalmology and surgical medicine, this balanced salt solution mimics the natural physiological composition of the human aqueous humor.

What Is BSS Plus and How Does It Work?

BSS Plus is an enriched, physiologically balanced intraocular irrigating fluid designed to maintain both the physical and biochemical health of ocular tissues during surgery. Standard physiological saline solutions lack critical ions and nutrients required by delicate internal eye tissues. BSS Plus supplies essential electrolytes sodium, potassium, calcium, magnesium, chloride, phosphate, and bicarbonate to maintain proper osmotic pressure and physiological pH within the eye’s anterior and posterior chambers.

Is BSS Plus FDA Approved?

Yes, this enriched intraocular irrigating solution is fully FDA approved. It received its initial regulatory approval in (October 1981) and remains a trusted standard for surgical irrigation during delicate ophthalmic operations.

What Is BSS Plus Used For?

• Surgical Intraocular Irrigation: Utilized as a continuous irrigating fluid during complex, prolonged intraocular surgical procedures, including vitrectomy, cataract extraction, and anterior segment reconstruction.
• Corneal Endothelial Protection: Formulated to protect and preserve corneal endothelial cell structural integrity and metabolic function during lengthy anterior or posterior segment surgeries.
• Retinal and Tissues Preservation: Maintains intraocular pressure and physiological hydration of intraocular tissues during complex vitreo-retinal procedures.

Before Taking BSS Plus: Contraindications & Precautions

Because BSS Plus is intended solely for localized intraocular irrigation during surgical procedures, its clinical precautions differ from systemic pharmaceutical therapies. It is introduced directly into the chambers of the eye by an ophthalmic surgeon. The primary clinical precautions involve verifying the absolute sterility, proper chemical reconstitution, and physical clarity of the solution prior to administration. Introducing improperly mixed or contaminated irrigating solutions into the intraocular environment can lead to severe localized tissue damage, endothelial cell loss, or intraocular infection.

Who Should Not Take BSS Plus?

• Patients with a known hypersensitivity or allergic reaction to any of the specific active chemical components contained within the reconstituted solution.
• This product must strictly not be administered as a standard systemic intravenous fluid infusion.
• The solution must not be used if the sterile container is damaged, if the reconstituted solution appears cloudy or discolored, or if visible precipitate has formed.

BSS Plus, Pregnancy & Fertility

Animal reproduction studies have not been conducted with BSS Plus. Systemic absorption following intraocular irrigation during localized ophthalmic surgery is negligible. Therefore, BSS Plus is not expected to cause fetal harm when administered to a pregnant patient during necessary eye surgery, nor is it expected to impact reproductive capacity or pass into breast milk in clinically significant quantities.

Tell Your Doctor Before Taking BSS Plus

Preoperative clinical discussions for patients undergoing eye surgery focus primarily on overall ocular health and surgical planning. Patients should inform their ophthalmic surgeon of any history of severe corneal dystrophies, pre-existing endothelial compromised states, severe glaucoma, or previous intraocular surgeries. This information helps the surgical team select the appropriate irrigating fluid to optimize postoperative corneal clarity and tissue recovery.

BSS Plus Dosage & Administration

The dosing and administration of BSS Plus are determined by the operating ophthalmic surgeon based on the specific surgical procedure, duration of the operation, and volume required to maintain proper intraocular pressure and fluid balance. It is supplied as a specialized two-part reconstitution kit to preserve the chemical stability of bicarbonate, dextrose, and glutathione until the time of surgery.

Standard BSS Plus Dosing

• There is no fixed milligram dosage for the patient; the volume of reconstituted irrigating solution used depends entirely on the requirements of the intraocular surgical procedure.
• Surgical volumes typically range from a few hundred milliliters to over one liter during lengthy, complex vitreo-retinal procedures.

How BSS Plus Is Administered

• BSS Plus is administered exclusively by an ophthalmic surgeon or trained surgical personnel via dedicated intraocular administration sets connected to surgical handpieces (such as phacoemulsification or vitrectomy probes).
• The two separate parts of the kit (Part 1 concentrate/diluent and Part 2 additive) must be mixed strictly using aseptic technique immediately prior to surgical use.
• Once reconstituted, the solution must be used within 6 hours and any unused portion must be safely discarded. Additives or additional medications must not be mixed directly into the BSS Plus solution, as this can alter pH, osmolality, or cause precipitate formation.

BSS Plus Clinical Efficacy & Research

Extensive clinical research in ophthalmic surgery establishes enriched irrigating solutions containing glutathione, bicarbonate, and dextrose as superior to un-enriched balanced salt solutions for prolonged intraocular procedures. Clinical studies evaluating corneal endothelial cell density post-surgery demonstrate that irrigating with BSS Plus results in significantly lower endothelial cell loss and reduced postoperative corneal pachymetry (corneal thickness/swelling) following complex cataract and vitrectomy operations. Pharmacological evaluations confirm that maintaining intraocular pH, osmotic balance, and metabolic support directly preserves the functional endothelial pump mechanism necessary for post-surgical corneal transparency.

BSS Plus Side Effects & Safety Profile

Because BSS Plus is localized to the intraocular space during surgery, systemic side effects are extraordinarily rare. Adverse reactions associated with its use are primarily ocular in nature and are often difficult to separate from potential complications related to the surgical procedure itself. Maintaining proper solution temperature, reconstitution protocol, and flow rates during surgery is essential to minimize localized tissue irritation.

Common BSS Side Effects (>10%)

• Mild, temporary postoperative corneal edema (swelling) associated with surgical manipulation and fluid exposure.
• Transient post-surgical ocular inflammation or mild anterior chamber cell flare.
• Temporary alterations in intraocular pressure following ophthalmic surgery.

Serious BSS Plus Adverse Events

• Severe corneal endothelial dysfunction or bullous keratopathy resulting from prolonged surgical trauma or improper fluid preparation.
• Endophthalmitis (severe intraocular infection) if aseptic technique is compromised during solution reconstitution or administration.
• Intraocular inflammation or toxic anterior segment syndrome (TASS) associated with accidental contamination or improper solution mixing.

Managing BSS Plus Side Effects

Pre-surgical preparation and strict adherence to reconstitution protocols prevent most solution-related complications. Postoperative ocular inflammation or elevated intraocular pressure is routinely managed by the ophthalmic surgeon using topical anti-inflammatory eye drops (corticosteroids) and pressure-lowering agents. If post-surgical corneal edema occurs, clinicians monitor the patient closely, utilizing hypertonic saline drops if indicated to assist in restoring corneal clarity.

BSS Plus Drug Interactions & What to Avoid

Because BSS Plus is used strictly as an intraocular irrigating fluid and is not administered systemically, classical systemic drug-drug interactions do not typically occur. However, physical and chemical interactions inside the irrigating bottle or intraocular chamber represent critical clinical concerns for the surgical team.

BSS Plus Drug-Drug Interactions

• Direct Additives: No drugs or supplemental chemical agents should be added directly to the BSS Plus irrigating container. Adding external medications can alter the solution’s delicate physiological pH, disrupt osmotic balance, or precipitate the active ingredients (such as calcium or phosphate salts).
• Intraocular Medications: If intraocular medications (such as intracameral antibiotics or miotics) are introduced during surgery, they should be injected separately via dedicated syringes rather than mixed into the primary irrigating reservoir.

BSS Plus, Food & Alcohol

As BSS Plus is an intraocular irrigating fluid used strictly during surgical procedures, interactions with dietary food and alcohol are not applicable. Patients undergoing eye surgery under local or general anesthesia follow standard preoperative fasting guidelines directed by their anesthesia team.

BSS Plus: Missed Dose, Overdose & Storage

Because BSS Plus is reconstituted and administered strictly by healthcare professionals in an operating room setting, patient-controlled dosing schedules do not apply. Storage and reconstitution guidelines must be followed rigorously by surgical staff to preserve solution efficacy and sterility.

Missed Dose of BSS Plus

Not applicable. BSS Plus is utilized as needed during surgical procedures at the discretion of the operating surgeon.

BSS Plus Overdose & Emergency

Overdose in the context of intraocular irrigation refers to excessive volume or excessive flow pressure within the eye. Operating surgeons continuously manage fluid inflow and outflow to maintain stable intraocular pressure, preventing mechanical trauma or structural fluid overload within the ocular chambers.

How to Store BSS Plus

Store the unmixed BSS Plus kit components at room temperature between 36°F and 77°F (2°C to 25°C). Avoid exposing the product to excessive heat. Do not freeze. Reconstitute Part 1 and Part 2 immediately prior to surgery using strict aseptic technique. Once reconstituted, store the solution at room temperature and use within 6 hours. Any solution remaining after 6 hours must be discarded.

BSS Plus Patient Management & Monitoring

Patient management around the use of BSS Plus centers on standard perioperative ophthalmic care. The surgical team ensures that the solution is prepared correctly, and the postoperative team monitors the patient’s visual recovery and ocular healing.

Tests Before Starting BSS Plus

• Preoperative ophthalmic examination, including baseline visual acuity, intraocular pressure measurement, and slit-lamp evaluation.
• Assessment of corneal endothelial health (such as specular microscopy) when evaluating high-risk patients with pre-existing corneal dystrophies.

Monitoring During BSS Plus Treatment

• Continuous intraoperative monitoring of intraocular fluid dynamics, tissue clarity, and eye pressure by the surgical team.
• Postoperative evaluation of corneal transparency, anterior chamber reaction, and intraocular pressure during standard post-surgical follow-up visits.

BSS Plus Do’s and Don’ts

• DO follow all post-surgical care instructions provided by your eye surgeon, including using prescribed eye drops as directed.
• DO protect your eye with a protective shield or glasses as instructed following surgery.
• DON’T rub your eye or apply unapproved over-the-counter drops during the post-surgical healing phase.
• DON’T mix any medications directly into the irrigating fluid reservoir if assisting in surgical preparation.
