Custom Lens Replacement (CLR)
Vision Correction Built on Trust
Custom Lens Replacement (CLR) is a proven, outpatient procedure that replaces your eye’s natural lens with a clear, artificial lens (intraocular lens, or IOL). It is similar to cataract surgery, but performed earlier, before cataracts begin to affect your vision. By replacing the ageing lens, CLR can restore clear vision at multiple distances while also preventing cataracts from developing in the future.
Who It Is For
CLR may be right for you if:
- You are over 50 and rely on reading glasses, bifocals, or progressives
- You are finding it harder to read, drive at night, or switch between distances
- You have been told you are not a suitable candidate for LASIK
- You want a long-term solution instead of continually updating prescriptions
- You are interested in avoiding cataract surgery later in life
Many patients come to us feeling frustrated by constantly changing vision and looking for something more permanent.
If that sounds familiar, the next step is simply understanding your options.


Benefits and Limitations
Our role is to help you understand what these mean for your lifestyle so you can make the right decision.
