Our top recommendation for CRT / Ortho-K Lenses : We recommend everyone to start with Unique Ph alone. If you like to have more cleaning power, you can combine Alcon Clear Care system with Unique Ph. If Unique Ph brand solution is not available, Boston Simplus can be used instead. Periodic use of Menicon Progent cleaner can remove stubborn protein buildups.
Our recommendation for Scleral Lenses : Alcon Clear Care to clean and store lenses then fill the lenses with Menicon Lacripure before inserting to eyes. Use of common soft contact lens “saline” solution to fill the lenses can cause lens irritation and lens intolerances issues. Blink Clear brand rewetting drops can be used to clear the blurry films while wearing lenses. Menicon progent cleaner can be added to maintain clarity of lenses.
For Hybrid lenses ( Synergeyes brand lenses) we recommend Alcon clear care to clean.

Typically, it takes about 3 to 7 days for a CRT patient to achieve a stable daytime correction, however it may take longer for higher prescription corrections.

Also patients who normally undergo frequent prescription changes are excellent candidates for CRT because of its flexibility. Additionally, due to the fact that CRT lenses are worn only at night, patients with sensitive eyes, mild dryness or contact lens sensitivity also make great candidates.
