Do scleral lenses hurt?
No. Most patients find scleral lenses more comfortable than smaller rigid lenses because the lens rests on the sclera rather than the sensitive cornea. There may be mild awareness during the first few days of wear, but actual pain is not expected and should be reported to your optometrist.
How long does it take to adapt?
Most patients adapt within one to two weeks. Initial wearing time is gradually increased over the first few days. By the end of the second week, most patients are wearing their lenses comfortably for a full day.
If you have worn rigid or gas-permeable lenses before, adaptation is usually faster.
How do I insert and remove scleral lenses?
Scleral lenses are filled with preservative-free saline and placed on the eye using a plunger or your fingertips. Removal uses a small suction tool.
We teach insertion and removal technique during your fitting visits and do not discharge you until you are confident with handling. Most patients are comfortable with the process after two or three practice sessions.
What if I drop or lose a lens?
Scleral lenses are custom-made, so a replacement lens can be ordered using your existing parameters. Contact the clinic and we can arrange a replacement.
Tips to reduce the risk:
- Always handle lenses over a clean towel or soft surface
- Keep your lens case and plunger with you when travelling
- Store your parameter card or take a photo of your lens specifications
How do I clean and care for scleral lenses?
Scleral lenses are cleaned daily with a hydrogen peroxide system or a GP-specific multi-purpose solution recommended by your optometrist. Lenses are stored in solution overnight.
Never use tap water on scleral lenses — it can introduce microorganisms that cause serious eye infections. We review the full care routine, including solution options and case hygiene, during your fitting visits.
How many hours a day can I wear them?
Most patients wear scleral lenses for 12 to 16 hours per day once fully adapted. Your optometrist will set a wearing schedule based on your eye health and comfort.
Some patients with dry eye conditions may benefit from brief midday removal and refilling of the saline reservoir. Your optometrist will advise if this applies to you.
Can I swim or shower in scleral lenses?
You should remove scleral lenses before swimming in pools, lakes, or hot tubs. Water exposure introduces infection risk. Showering with lenses in is generally acceptable if you keep your eyes closed and avoid direct water contact with the lenses.
What if my vision is foggy or the lens fogs up?
Midday fogging — where vision becomes hazy after several hours of wear — can happen if debris or proteins accumulate in the fluid reservoir. Removing the lens, rinsing it, refilling with fresh saline, and reinserting usually resolves the issue. If fogging is frequent, your optometrist may adjust the lens fit or recommend a different filling solution.
