What Riboflavin (Vitamin B2) ophthalmic is used for
Riboflavin (Vitamin B2) ophthalmic is a crucial medicine used during a surgical procedure known as collagen cross-linking (CXL), sometimes also called C3R. This procedure is performed to treat specific eye conditions that affect the cornea, the clear front part of your eye.
Specifically, it is used for:
- Keratoconus: This is a condition where the cornea thins and gradually bulges outwards into a cone shape, leading to blurred and distorted vision.
- Post-LASIK Ectasia: This is a rare complication that can occur after LASIK surgery, where the cornea weakens and bulges forward, similar to keratoconus.
In both these conditions, the cornea becomes weak and loses its normal shape. The cross-linking procedure with Riboflavin aims to strengthen the cornea and prevent further worsening of the condition, helping to preserve your vision.
How it works
Riboflavin (Vitamin B2) ophthalmic works by strengthening the cornea, which is the transparent front part of your eye. When you have conditions like keratoconus or post-LASIK ectasia, the collagen fibres that make up your cornea become weak, causing the cornea to bulge and distort your vision.
During the corneal cross-linking (CXL) surgery, Riboflavin solution is applied directly to your cornea. This special solution soaks into the corneal tissue. Once the Riboflavin has adequately penetrated the cornea, your ophthalmologist will shine a controlled amount of UV-A light onto your eye. This UV-A light activates the Riboflavin.
When activated, Riboflavin helps to create new, stronger bonds between the existing collagen fibres within your cornea. Think of it like adding extra support beams to a structure. These new bonds make the cornea much stiffer and more stable. This stiffening effect is vital because it helps to halt the progression of the underlying condition, preventing the cornea from thinning further and bulging outwards. By making the cornea stronger, the procedure aims to preserve your vision and prevent the need for more invasive treatments like a corneal transplant in the future.
How it’s used
Riboflavin (Vitamin B2) ophthalmic is not a medicine you take home or use by yourself. It is a specialized solution that is used exclusively by a qualified ophthalmologist during the corneal cross-linking (CXL) surgical procedure in a hospital or clinic setting.
During the CXL procedure, the ophthalmologist will prepare your eye. Then, the Riboflavin 0.1% solution will be carefully applied to your cornea. This application is done repeatedly, typically every 2-3 minutes, throughout the cross-linking procedure. The exact duration and frequency will be determined by your ophthalmologist based on the specific protocol for your treatment.
After the Riboflavin has been absorbed by your cornea, your eye will be exposed to a special UV-A light, which activates the Riboflavin to strengthen your corneal tissue. You will be under the care and supervision of the medical team throughout the entire process. It is crucial to understand that this medicine is for hospital use only and is never intended for self-administration.
Always follow your ophthalmologist’s exact instructions.

Good to know
Prescription eye medicine — use only as directed by a qualified ophthalmologist.

Precautions & side effects
While Riboflavin (Vitamin B2) ophthalmic is a safe and effective part of the corneal cross-linking (CXL) procedure, there are important points to remember:
- Not a take-home drop: This medicine is strictly for use during the CXL procedure in a hospital or clinic by a specialist. It is never given to patients to take home or use on their own.
- Halts progression, does not reverse: It is important to understand that CXL with Riboflavin primarily works to stop the worsening of conditions like keratoconus. It does not typically reverse any existing vision distortion or corneal bulging that has already occurred. The goal is to preserve your current vision and prevent further deterioration.
- Common in India: Keratoconus, the primary condition treated with CXL, is quite common in India and often presents in younger individuals. Early diagnosis and treatment with CXL can be very beneficial in managing the condition.

Understanding Keratoconus and Post-LASIK Ectasia
The cornea is the clear, dome-shaped front surface of your eye. It plays a vital role in focusing light onto the retina, allowing you to see clearly. In conditions like keratoconus and post-LASIK ectasia, the cornea gradually thins and weakens, causing it to bulge forward into an irregular, cone-like shape. This change in shape distorts the light entering your eye, leading to blurred vision, glare, and light sensitivity. Keratoconus often begins in adolescence or early adulthood and can progress over time. In India, it is particularly important to diagnose and treat keratoconus early, as it can affect young people significantly. Post-LASIK ectasia is a rare but serious complication that can occur after LASIK surgery, where the cornea weakens and bulges, similar to keratoconus. Both conditions can severely impact your quality of life and vision if left untreated.
Corneal cross-linking (CXL) with Riboflavin is a revolutionary procedure designed to strengthen the cornea and halt the progression of these conditions. By making the cornea stiffer and more stable, CXL aims to prevent further vision loss and reduce the need for more complex surgeries like corneal transplantation in the future. Your ophthalmologist will carefully assess your condition to determine if CXL is the right treatment option for you.
General Eye Care and Hygiene
While Riboflavin ophthalmic is used in a hospital setting, maintaining good eye hygiene and general eye care practices is always important for overall eye health, especially when dealing with eye conditions. Always wash your hands thoroughly with soap and water before touching your eyes or applying any eye drops (if prescribed for home use). Avoid rubbing your eyes vigorously, as this can sometimes worsen conditions like keratoconus. If you wear contact lenses, ensure they are cleaned and stored according to your eye care professional’s instructions to prevent infections. Always use fresh, sterile solutions for contact lens care. Protect your eyes from excessive sun exposure by wearing sunglasses that block UV rays, as this can be beneficial for general eye health. If you experience any discomfort, redness, discharge, or changes in vision, it is crucial to consult your ophthalmologist promptly.
When to Seek Medical Help
Your ophthalmologist is your best resource for any concerns regarding your eye health. After a corneal cross-linking procedure, you will receive specific post-operative instructions. It is vital to follow these instructions carefully and attend all scheduled follow-up appointments. If you experience any unexpected symptoms after your procedure, such as severe pain, sudden decrease in vision, persistent redness, discharge from the eye, or fever, contact Pristine Eye Hospitals or your ophthalmologist immediately. These could be signs of a complication that requires urgent attention.
