- Device directly aligns visual axis of both patient and surgeon critical to centration of corneal marks and subsequent lens implant
- Patented design allows surgeon stereopsis for proprioception without risk of parallax or cross fixation
- It is imperative to premark the eye with the patient sitting vertically to avoid cyclorotation.
- Surgeon simply covers the fellow eye in order to mark the surgical eye on the visual axis.
- Eliminates guesswork as to where the patient is fixating

“I have used almost every marking system when utilizing toric implants. Your zero parallax visual system (utilizing your marker) in my hands is by far the most consistent, cost effective and simple way to mark the appropriate axis for toric IOLs. I especially appreciate not having to mark the cornea in the preop and then mark the cornea again at the time of surgery. I believe having to mark the cornea twice introduces an additional source of potential error. The toric marker, combined with your visual system is an elegant and simple way to make a fine mark which is easily seen at the time of surgery. Additionally, your centering device eliminates the error or the mark not being centered on the cornea (another source of potential error).”
“The corneal light reflex established by the LED aligns the patient objectively to the surgeon’s stereo vision. I personally have them look directly at my right eye as I mark and then utilize the visual axis light reflex as the center of the marking pattern reference.
This approach has ended the debate about centration. The system virtually eliminates issues with centering related to the capsular bag opening and the pupil. This is very useful for centration during surgery where the pupil is dilated and the entrance pupil concept is obscure. I used to grimace with ReSTOR rings that were not concentric with the pupil. At first this was disconcerting however the next day they look great and most importantly, see great.
Centering upon the visual axis eliminates pharmacologic concern relative to the pupil. All diagnostic instruments such as manual keratometers, topographers, autorefractors, OCT’s, wave front aberrometers center on the patient’s line of sight or visual axis so using this approach in surgery is consistent with our clinical methods. This is the best way to mark and center multifocal and toric IOL’s. In my opinion, this ends the debate over centration.”
