Contact lens issues


Hello Dr.
Gao: I apologize for interrupting your busy schedule.
I would like to ask if high-oxygen permeability rigid gas permeable (RGP) contact lenses need to be protein cleaned.
I have been wearing them for 10 years without any protein removal, but recently a doctor advised me to do so, while another doctor said it is unnecessary.
Does not performing protein removal affect the lenses? Will protein removal damage the lenses and shorten their lifespan?

Dr. Gao Pilin reply Ophthalmology


Hello, although rigid gas permeable contact lenses are less prone to protein deposits compared to soft contact lenses, some deposits can still occur, and there may also be lipid deposits present.
If they have been worn for a long time, it is still advisable to clean them to remove protein.
Cleaning will not damage the lenses, so you can rest assured.
Thank you for your message.

When it comes to rigid gas permeable (RGP) contact lenses, the question of whether or not to remove protein deposits is an important one. Over time, protein and lipid deposits can accumulate on the surface of contact lenses, which can affect both comfort and vision. While RGP lenses are known for their durability and oxygen permeability, they are not immune to the effects of these deposits.

Firstly, it is essential to understand that protein deposits are a natural occurrence for many contact lens wearers. The human tear film contains proteins that can adhere to the lens surface, especially if the lenses are worn for extended periods without proper cleaning. If these deposits are not removed, they can lead to discomfort, reduced visual acuity, and even an increased risk of eye infections. Therefore, regular cleaning and maintenance of your lenses are crucial for maintaining eye health.

Regarding the necessity of protein removal, many eye care professionals recommend using a protein remover solution specifically designed for contact lenses. This solution helps to break down and remove protein deposits effectively. While some individuals may not experience significant issues without protein removal, it is generally advisable to incorporate this step into your lens care routine, especially if you have been wearing the same lenses for an extended period, such as ten years.

As for the concern about whether removing protein will damage the lenses or shorten their lifespan, the answer is generally no. When used correctly, protein removers are safe for RGP lenses and should not harm them. However, it is crucial to follow the manufacturer's instructions and the guidance of your eye care professional. Overuse or improper application of cleaning solutions can potentially lead to lens damage, so moderation and adherence to recommended practices are key.

If your eye care provider has suggested that you start removing protein deposits, it may be a sign that your lenses have accumulated more deposits than is ideal for your eye health. Ignoring this advice could lead to discomfort or complications down the line. Therefore, it is wise to take their recommendation seriously and incorporate protein removal into your lens care routine.

In summary, while it may not be strictly necessary for everyone to remove protein from their RGP lenses, doing so can enhance comfort, maintain clear vision, and reduce the risk of complications. Regular cleaning and maintenance, including protein removal, are essential components of responsible contact lens wear. If you have any concerns or experience discomfort, it is always best to consult with your eye care professional for personalized advice tailored to your specific situation.
