What Sodium Hyaluronate + Chondroitin Sulfate is used for
Sodium Hyaluronate + Chondroitin Sulfate is a vital medicine used by ophthalmologists (eye specialists) during eye surgeries. Its primary purpose is to protect the delicate structures inside your eye, particularly the corneal endothelium, during the surgical procedure.
- Endothelial protection during cataract surgery
- Endothelial protection during anterior segment surgery
How it works
This medicine is a type of ‘viscoelastic’ gel. Think of it as a protective, slippery coating. During eye surgery, the surgeon carefully introduces this gel into your eye. It works by forming a protective layer that coats and shields the corneal endothelium. The corneal endothelium is a very thin and crucial layer of cells on the inside surface of your cornea (the clear front part of your eye). This layer is responsible for keeping your cornea clear and healthy. By coating it, Sodium Hyaluronate + Chondroitin Sulfate helps protect these cells from potential damage during the surgical instruments’ movements and fluid flow within the eye. This protection is essential for a successful surgery and good vision recovery.
How it’s used
Sodium Hyaluronate + Chondroitin Sulfate is not a medicine you will use at home. It is an ‘intraocular gel,’ meaning it is used inside the eye by your ophthalmologist during surgery. The surgeon will carefully introduce the gel into your eye at the beginning of the procedure to provide protection. Once the surgery is complete, the surgeon will ensure that the gel is fully removed from your eye before the procedure concludes. This precise application and removal are critical for the safety and success of the surgery.
Always follow your ophthalmologist’s exact instructions.

Prescription eye medicine — use only as directed by a qualified ophthalmologist. This page is for general education and is not a substitute for professional medical advice, diagnosis or a prescription. Do not self-medicate or reuse an old prescription. This is given only by specialists in a hospital or clinic setting and is never for self-use.
Precautions & side effects
While Sodium Hyaluronate + Chondroitin Sulfate is a safe and effective medicine when used by a skilled surgeon, there are important considerations:
- Full Removal is Key: This gel is a ‘dispersive viscoelastic.’ It is designed to coat and protect. However, it is crucial that your surgeon ensures it is fully removed from your eye at the end of the surgery.
- Avoiding IOP Spike: If any residual gel is left in the eye, it could potentially lead to a temporary increase in intraocular pressure (IOP), which is the pressure inside your eye. Your surgeon is well aware of this and takes all necessary steps to prevent it.
- Prescription Medicine: This is a prescription eye medicine and is strictly for use by a qualified ophthalmologist in a hospital or clinic setting. It is never for self-use.

Understanding Cataract and Anterior Segment Surgeries
Cataract surgery is one of the most common and successful eye surgeries performed worldwide, including here in India. A cataract is a clouding of the natural lens inside your eye, which leads to blurry vision, difficulty seeing in dim light, and sometimes a yellowish tint to your vision. It often develops with age. During cataract surgery, your eye surgeon removes this cloudy lens and replaces it with a clear artificial lens, restoring your vision. ‘Anterior segment surgery’ is a broader term that refers to any surgical procedure performed on the front part of your eye, which includes the cornea, iris, and lens. Both these types of surgeries require extreme precision and care from the surgeon.
During these delicate procedures, the internal structures of your eye, especially the very thin and vital layer of cells called the corneal endothelium, need protection. The corneal endothelium is like the ‘pump’ that keeps your cornea clear by regulating fluid balance. Damage to these cells can lead to corneal swelling and blurred vision. This is where medicines like Sodium Hyaluronate + Chondroitin Sulfate play a crucial role, acting as a protective shield.
General Advice for Eye Surgery and Recovery
If you are undergoing eye surgery, it’s natural to have questions and perhaps feel a little anxious. Rest assured that modern eye surgeries are highly advanced and performed with great care. Your ophthalmologist and the hospital staff will provide you with detailed instructions before and after your surgery. It’s vital to follow these instructions carefully for a smooth recovery and the best possible outcome.
Before surgery, you might be asked to stop certain medications or use specific eye drops. On the day of surgery, make sure you arrive on time and inform the staff of any last-minute concerns. After surgery, you will typically be given a set of eye drops to use, which are crucial for preventing infection and reducing inflammation. It’s very important to use these drops exactly as prescribed, even if your eye feels fine. Avoid rubbing your eyes, lifting heavy objects, or bending over excessively during the initial recovery period, as advised by your doctor.
General Eye Hygiene and When to Seek Help
Maintaining good eye hygiene is always important, especially after any eye procedure. Always wash your hands thoroughly with soap and water before touching your eyes or applying any eye drops. Avoid sharing eye drops or towels. If you experience any unusual symptoms after surgery, such as severe pain, sudden worsening of vision, excessive redness, discharge, or flashes of light, do not hesitate to contact your ophthalmologist immediately. These could be signs of a complication that needs prompt attention. Remember, your doctor is your best resource for any concerns about your eye health. Regular follow-up appointments after surgery are essential to monitor your recovery and ensure the long-term health of your eyes.
Frequently asked questions
What is Sodium Hyaluronate + Chondroitin Sulfate used for?
Sodium Hyaluronate + Chondroitin Sulfate is a special gel used by eye surgeons during cataract surgery and other surgeries on the front part of the eye (anterior segment surgery). Its main purpose is to protect the delicate inner lining of the cornea, called the corneal endothelium, during the surgical procedure.
How does Sodium Hyaluronate + Chondroitin Sulfate work?
This medicine works as a 'dispersive viscoelastic.' This means it forms a protective, slippery coating inside your eye. During surgery, it coats and shields the corneal endothelium, which is a crucial layer of cells that keeps your cornea clear. This protection helps prevent damage to these cells during the surgical process.
What are the common Indian brands for Sodium Hyaluronate + Chondroitin Sulfate?
Common brands for this medicine include Viscoat and similar products available in India.
How is Sodium Hyaluronate + Chondroitin Sulfate used?
This medicine is an 'intraocular gel,' meaning it is used directly inside your eye by a qualified eye surgeon during the operation. It is introduced at the beginning of the surgery for protection and then carefully removed by the surgeon at the end of the procedure. It is never for self-use at home.
Do I need a prescription for Sodium Hyaluronate + Chondroitin Sulfate?
Yes, Sodium Hyaluronate + Chondroitin Sulfate is a prescription eye medicine. It is strictly for hospital use and administered only by a qualified ophthalmologist. It is not available for self-medication.
What precautions should be taken with Sodium Hyaluronate + Chondroitin Sulfate?
The main precaution is that the surgeon must ensure the gel is fully removed from your eye at the end of the surgery. If any gel remains, it could potentially cause a temporary increase in the pressure inside your eye (intraocular pressure or IOP). Your ophthalmologist is well aware of this and takes all necessary steps to ensure its complete removal.
