Scleral lenses are a specialized type of contact lens that covers a larger area of the eye than traditional lenses, vaulting over the cornea. This design offers numerous benefits for individuals with complex eye conditions, but understanding their lifespan is crucial for maintaining eye health and vision clarity. So, how long do scleral contacts last? The answer isn't a simple number, as it depends on several factors.
How Long Can I Wear My Scleral Lenses Per Day?
This is a frequently asked question, and the answer is determined by your eye doctor. While some individuals can wear their scleral lenses for extended periods, even overnight, this isn't always the case. Your individual needs and eye health will dictate the appropriate wear schedule. Some might wear them for 12 hours a day, others for the full 24. Always follow your optometrist's recommendations. Improper wear can lead to complications like infections or corneal damage.
How Often Should I Replace My Scleral Lenses?
The replacement schedule for scleral lenses varies depending on the lens material and your eye doctor's assessment. Generally, replacement schedules fall into these categories:
- Daily Disposable Scleral Lenses: These are removed and discarded after each use, eliminating the need for cleaning and reducing the risk of infection. They offer the highest level of hygiene but come with the highest cost.
- Frequent Replacement Scleral Lenses: These lenses may be replaced weekly, bi-weekly, or monthly, depending on the material and your individual needs. Proper cleaning and disinfection are essential to prevent complications.
- Extended Wear Scleral Lenses: In some cases, under strict medical supervision, scleral lenses can be worn for extended periods, potentially even overnight. However, this is not suitable for everyone and requires careful monitoring.
Your eye care professional will determine the optimal replacement schedule based on your specific needs and the lens material. Factors like the presence of allergies, dry eye syndrome, or other eye conditions will impact the recommendation. Never deviate from this schedule without consulting your doctor.
What Factors Affect the Lifespan of Scleral Lenses?
Several factors influence how long your scleral lenses will last before requiring replacement:
- Lens Material: Different materials have different lifespans. Some materials are more durable and resistant to damage than others.
- Cleaning and Disinfection: Proper cleaning and disinfection practices are vital. Failing to clean your lenses correctly can shorten their lifespan and increase the risk of infection.
- Individual Eye Health: Conditions like dry eyes, allergies, or infections can affect the longevity of your lenses.
- Wear and Tear: Normal wear and tear from daily use will eventually necessitate replacement. Microscopic scratches and debris accumulation can impact vision clarity and lens integrity.
- Manufacturing Quality: Higher quality lenses tend to have a longer lifespan.
How Can I Extend the Life of My Scleral Lenses?
While you cannot indefinitely extend the lifespan beyond your eye doctor’s recommended replacement schedule, proper care can maximize their useful life:
- Follow Cleaning and Disinfection Instructions: Meticulously follow the instructions provided by your eye care professional and lens manufacturer.
- Handle Lenses Carefully: Avoid scratching or damaging the lenses during cleaning and insertion.
- Store Lenses Properly: Store your lenses in a sterile case with appropriate solution when not in use.
- Regular Eye Examinations: Schedule regular check-ups with your eye doctor to monitor the health of your eyes and lenses.
How Much Do Scleral Lenses Cost?
The cost of scleral lenses can vary significantly, depending on the lens material, replacement schedule, and the complexity of your prescription. They are generally more expensive than traditional contact lenses. Discuss cost and insurance coverage with your eye care professional.
By diligently following your eye doctor's instructions and practicing proper lens care, you can ensure that your scleral lenses provide clear, comfortable vision for as long as possible within the recommended replacement schedule. Remember, maintaining good eye hygiene is paramount to preserving both your vision and your lenses' lifespan.
