Keeping your eyes safe when wearing scleral lenses
Scleral lenses have become increasingly popular in recent years due to their ability to provide superior comfort and vision correction for individuals with certain eye conditions. These lenses are designed to vault over the cornea and rest on the sclera, providing a comfortable and stable fit for those who struggle with traditional contact lenses.
One of the key components of caring for scleral contact lenses is the use of saline solution for cleaning and storing the lenses. Saline solution is a sterile solution that is used to rinse, clean, and store contact lenses. However, there are two main types of saline solution available for use with scleral lenses: buffered and non-buffered saline.
Buffered saline solution contains buffering agents that help to maintain the pH balance of the solution, making it more stable and less likely to cause irritation to the eyes. Non-buffered saline, on the other hand, does not contain these buffering agents and may be more prone to changes in pH levels, potentially causing discomfort or irritation when used with scleral lenses.
So, what are the differences between buffered and non-buffered saline for scleral contact lenses, and which is the best option for lens wearers? Let’s explore the advantages and disadvantages of each type of saline solution.
Advantages of Buffered Saline
Buffered saline solution is specifically formulated to maintain a stable pH balance, making it less likely to cause irritation or discomfort when used with scleral lenses. This can be especially important for individuals with sensitive eyes or those who wear their lenses for extended periods of time.
Additionally, the buffering agents in buffered saline help to prevent the growth of bacteria and other microorganisms in the solution, reducing the risk of eye infections and other complications. This can provide added peace of mind for individuals who are concerned about the cleanliness and safety of their lenses.
Buffered saline solution is also less likely to cause stinging or burning when used to rinse or clean scleral lenses, making it a more comfortable option for many lens wearers. Overall, buffered saline may be the preferred choice for individuals looking for a reliable and gentle solution for caring for their scleral lenses.
Advantages of Non-buffered Saline
Non-buffered saline solution is a more basic and straightforward option for cleaning and storing scleral lenses. Some individuals may prefer non-buffered saline because it does not contain any additional chemicals or additives that could potentially cause irritation or allergic reactions.
Non-buffered saline is also less expensive than buffered saline, making it a more cost-effective option for individuals who are looking to save money on their lens care routine. This can be particularly appealing for individuals who wear their lenses on a daily basis and go through saline solution quickly.
Additionally, some individuals may find that non-buffered saline is more readily available at drugstores and online retailers, making it a convenient option for those who need to purchase saline solution on a regular basis.
Which is the Best Option for Scleral Lenses?
Ultimately, the choice between buffered and non-buffered saline for scleral lenses will depend on the individual needs and preferences of the lens wearer. Some individuals may find that buffered saline provides a more comfortable and reliable option for caring for their lenses, while others may prefer the simplicity and affordability of non-buffered saline.
It is important for lens wearers to consult with their eye care provider to determine which type of saline solution is best suited for their specific needs. Your eye care provider can provide recommendations based on your lifestyle, sensitivity to chemicals, and any underlying eye conditions that may impact your lens care routine.
Frequently Asked Questions about Saline for Scleral Lenses
- Can I use regular saline solution for scleral lenses?
Generally, it is not recommended to use regular saline solution for scleral lenses. Regular saline may not be sterile or formulated specifically for use with contact lenses, which could increase the risk of eye infections. Ask you doctor about the appropriate brands of off-label saline that would be best for your scleral lens needs. - How often should I change the saline solution in my lens case?
It is recommended to change the saline solution in your lens case every time you use your lenses. This helps to ensure that the solution remains sterile and effective for cleaning and storing your lenses. - Can I use saline solution to rinse my lenses before inserting them?
Yes, you can use saline solution to rinse your scleral lenses before inserting them. This helps to remove any debris or buildup on the lenses and can improve comfort and clarity when wearing the lenses. However, you should also be using some form of disinfectant daily to ensure your eyes stay healthy. - Is it safe to mix buffered and non-buffered saline solutions?
It is not recommended to mix buffered and non-buffered saline solutions, as this could alter the pH balance of the solution and potentially cause irritation or discomfort when using the solution with your lenses. - Can I use saline solution as a substitute for contact lens solution?
No, saline solution is not a substitute for contact lens solution. Contact lens solution is specifically formulated to clean, disinfect, and store contact lenses, whereas saline solution is primarily used for rinsing and storing lenses temporarily. - How should I store my saline solution for scleral lenses?
Saline solution for scleral lenses should be stored in a clean, dry place at room temperature. Avoid storing the solution in direct sunlight or extreme temperatures, as this could impact the effectiveness of the solution. - Can I use saline solution to clean my scleral lens case?
Yes, you can use saline solution to clean your scleral lens case. Simply rinse the case with saline solution and allow it to air dry before storing your lenses in the case. - Can I use saline solution to remove protein deposits from my scleral lenses?
