Many individuals with glaucoma require vision correction to see clearly. Contact lenses are a popular option for those who want an alternative to eyeglasses. However, when considering these, it’s important to be aware of the relationship between glaucoma and contact lenses. Here is all you need to know if you are a glaucoma patient, and want to use contact lenses.
Benefits of Contact Lenses for Glaucoma Patients
Contact lenses offer several advantages for individuals with glaucoma, just like others:
- Improved field of vision: Contact lenses provide a wider field of vision compared to glasses, which can be especially helpful for glaucoma patients who have peripheral vision loss. This does not mean that the field loss due to glaucoma is in anyway reversed or mitigated. However, the field of vision with contact lenses is wider than with glasses.
- Better stability: Contact lenses don’t slip or fog up, ensuring stable vision even in challenging conditions.
- Cosmetic appeal: Many people prefer the appearance of contact lenses over eyeglasses, enhancing their self-esteem.
Types of Contact Lenses
There are various types of contact lenses available, each with its own advantages and considerations for glaucoma patients:
Soft Contact Lenses
- Soft contact lenses are made from a flexible, water-containing material that conforms to the shape of the eye.
- They are comfortable to wear and come in various options, including daily disposable and extended wear.
- Some soft contact lenses are designed for astigmatism correction, which can be beneficial for patients with glaucoma.
Rigid Gas Permeable (RGP) Contact Lenses
- RGP lenses are made from a rigid, oxygen-permeable material.
- They provide excellent visual acuity and are suitable for individuals with irregular corneas or astigmatism.
- RGP lenses can maintain their shape, potentially assisting with vision stability.
Scleral Contact Lenses
- Scleral lenses are large, gas-permeable lenses that rest on the white part of the eye (sclera).
- They vault over the cornea, providing a smooth optical surface that can compensate for irregularities caused by glaucoma or other eye conditions.
- Scleral lenses can be particularly beneficial for individuals with severe corneal irregularities.
Considerations for Glaucoma Patients
While contact lenses offer numerous advantages, glaucoma patients should be aware of specific considerations when using them:
Intraocular Pressure (IOP) Monitoring
- Some types of contact lenses, particularly rigid lenses, can potentially impact IOP measurements.
- Patients should inform their eye doctor if they wear contact lenses to ensure accurate eye pressure readings during eye exams.
Glaucoma, Contact lenses, Dry Eye and Ocular Comfort
Glaucoma patients often have coexistent dry eyes. This can be worsened due to contact lens use.
Glaucoma Medication and Contact Lenses
You must not use glaucoma medication with the contact lens in the eye, unless specifically told by the doctor to do so.
Regular Eye Exams
- Routine eye exams are essential for glaucoma patients who wear contact lenses.
- Regular monitoring helps ensure that the lenses are not contributing to elevated IOP or causing other issues.
Proper Hygiene
- Maintaining good hygiene when handling contact lenses is crucial to prevent eye infections.
- Glaucoma patients should follow their eye doctor’s instructions for cleaning and disinfecting lenses.
Glaucoma and Contact Lens Care
Proper care and maintenance of contact lenses are critical for all wearers, but it’s especially important for individuals with glaucoma. Here are some essential tips for maintaining eye health while wearing contact lenses:
Cleanliness and Hygiene
- Wash your hands thoroughly before handling contact lenses.
- Use a recommended cleaning and disinfecting solution to clean your lenses.
- Avoid water exposure, including swimming or showering, while wearing contact lenses.
Follow a Strict Replacement Schedule
- Adhere to your eye doctor’s recommended replacement schedule for your specific type of contact lenses.
- Overusing lenses can increase the risk of eye infections and discomfort.
Attend Regular Eye Exams
This is critical to monitor your glaucoma as well as contact lens care. Moreover, you must discontinue wearing your contact lenses in case of any redness r irritation and contact your eye doctor immediately.
