Always wash and rinse your hands thoroughly and dry them with a lint-free towel/tissue before handling contact lenses. All traces of soap, perfumes, hair-spray, creams and lotions should be removed from your hands and around your eyes.
To avoid confusion make a habit of inserting the same lens - generally the right lens - first. You will notice that the right lens is green and the left lens blue. Minimise the risk of lens loss by plugging the sink or using a paper towel over the drainage opening.
This is to be done in the morning upon wakening. First use your index finger to push up your bottom eyelid and ensure that the retainer lenses are moving and are not bound. Bound lenses are stuck in place on your eye due to mucous adhesion – this is normal in Ortho-K lenses. To unbind a lens, press firmly on the white of your eye at the edge of your cornea at 12 and 6 o’clock several times.
Suction removal tools can be used to easily remove your lenses. These are simply placed on the lens and taken out of the eye. However, make sure you can remove your lenses manually in case you do not have a suction tool on your person. Purchase suction tools from our shop here.
CAPTION: Suction tools available. The green and blue style are the most popular for ortho-K lenses.
Always clean your lenses after wear. An effective cleaning process is vital to ensure comfortable, hygienic and infection-free contact lens wear. With correct cleaning, contact lenses will feel better on your eyes, allow better eye health and vision, and dramatically reduce bacteria and other contaminants.There are several types of rigid lens cleaning solutions: Peroxide based systems like AO Sept and multipurpose rigid lens solutions like Menicare and Boston Simplus. There are several steps involved in cleaning and storing Ortho-K lenses that vary depending on the system:
These solutions work by having your contact lenses immersed and sterilised in 3% hydrogen peroxide. Over the course of a 6 hour period the catalyst in the case converts the hydrogen peroxide into water and oxygen gas. This cleaning solution has the advantage that when your lenses are removed from the case they require no rinsing as they are covered only in sterile, non-preserved water. They also generally require no rubbing step, which decreases the risk of accidental breakage. The case can be left to air dry when not in use, and should be replaced with each new bottle of solution. AO Sept now had the addition of Hydraglyde, an ingredient which improves the wettability of your contact lenses, making them more useful for scleral patients with long day-wear times.
To clean your lenses fill the case up to the line, place your lenses in the correct cage-holder. Then submerge the case and screw closed. Take care when transporting the case as sometimes the small gas-release hole can leak solution.
Care should be taken not to get the un-neutralised peroxide in your eyes as this will sting painfully. If this occurs rinse thoroughly with water and contact your optometrist if the pain persists or your vision is affected. Find AoSept at our shop here.

Patients are advised to use a deeper protein removal product such as Progent at least every month. To use Progent combine the A and B vials in a lens case and submerge your lenses in this for 30 mins. Ensure your lenses are thoroughly rinsed and cleaned after using Progent before inserting into your eyes. Find Progent at our shop here.
Follow up appointments are vital to the monitoring and success of your new Ortho-k procedure. The first follow up appointment will be scheduled for the day after your first night of wear. The other follow up appointments will be determined by your Ortho-K practitioner based on your response to the first night of Orthokeratology therapy and the severity of your vision correction.
Ortho-K contact lenses are made of a strong polymer which resists damage in normal wearing circumstances. However, they can still break if mishandled. There are some tricks you can learn to minimise this chance.
To increase comfort and oxygen permeability, Ortho-K lenses are designed to be as thin as possible without compromising their structural integrity: most are 0.2mm thick or less. Because the lenses weigh very little, if you drop one it should not break unless it is then trampled on. If a lens falls on the floor, keep your feet still until you have spotted it. If you cannot see well without your lens, call to a friend or family member to help and remember to caution them to be careful where they tread!
The lenses are quite small and prone to fall into difficult to retrieve places such as down the sink-hole! Especially when you are learning how to insert and remove your lenses, make sure you use your lenses in a controlled environment such as a quiet bathroom with the plug inserted, or on a table with a clean towel laid flat. This way, if your lens drops you can find it easily and reduce the risk of breakage.
CAPTION: Mishandling a lens: Pushing down on the lens; Removing from suction tool too firmly; Forcing lens to bend while cleaning
It is very rare for a lens to break in your eye unless something hits your eye or your removal technique is incorrect/very forceful. The solutions you use to clean your lenses will not weaken or degrade them ‒ not even the powerful Progent fortnightly deep cleaner.
We understand that when you are learning how to use your lenses you may be inadvertently forceful during insertion, removal or cleaning. Because of this we offer a 1 month manufacturer’s replacement warranty on accidental breakages. Outside of this period, your lens is not covered by a warranty and the lens will need to be replaced at your cost if damaged or lost. If you break a lens within 18 months of its original purchase/fit then we are happy to offer 50% off the price. Outside of this 18 month period the lens will be full-price.
Normally a lens will take less than one week to arrive from the lab when ordered. If you are very dependent on the lens, we will of course ask our lens company to manufacture it as soon as possible. Because of the inevitable waiting time, we encourage all rigid lens wearers to have a spare set of lenses available for a situation where a lens is lost or broken. We also offer 50% off the full price for a spare lens if purchased within 12 months of the original.
If you do lose or damage a lens, please don’t fret, just give our friendly team a call and we will arrange a replacement as quickly as we can.
