Pros and Cons of CRT lenses

Getting a child to wear glasses or contact lenses which can be frustrating for a parent.


You want your child to be able to see the best they can with the proper prescription, but you also want them to be comfortable. So where do you compromise if they won’t wear correction?


Invision Eyecare is happy to offer a solution to your problem: Corneal Refractive Therapy, or CRT.


What is CRT?


CRT is a non-surgical procedure designed to remove the need for glasses or contacts. All you need to do is wear a lens at night which will correct the shape of your eyes leaving you ready for a day without glasses or contacts. While CRT is primarily to treat myopia or nearsightedness, our doctors can help you decide if this treatment is right for you.


Unlike traditional "soft lenses" that are disposable, CRT lenses are classified as "hard lenses" and act like a retainer on your eyes to help shape them into the proper sphere it needs to be to correct your vision.



What are the pros of CRT lenses?


CRT lenses give you a great solution to having to be dependent on corrective lenses.


No more depending on looking through glasses frames, cumbersome contacts, or switching between the two throughout the day. All you need to do is take them out every morning, and then you're good to go for the rest of the day.


CRT lenses also do not require a surgical procedure. This means you can use them at a much younger age. Alternatives like LASIK require both surgery and more stable, unchanging prescription over time, which is typically only seen in older candidates. LASIK can also have a complicated healing process which can impact the overall effectiveness.


Another great benefit, if you decide you don't want to keep wearing your CRT lenses at night, you don't have to. Switch back to wearing your glasses or contacts during the day and be on your way!


What are the cons of CRT lenses?


The effects of CRT lenses can take some time to take effect. There may be a chance you will need to wear your glasses or contacts in the evening, especially when you first get them.


The process to prepare to get your CRT lenses can take some time as well. You need to meet with your optometrist multiple times to ensure the prescription and fit of the lenses are correct, train your eyes to get used to your lenses and ensure they are properly shaping your cones once you start wearing them which can take about an hour and a half.


Because this is a complicated – and new – process, your insurance may not always cover CRT lenses.
