Résumé
Toric Intraocular lenses (IOLs) are supposed to be aligned at a particular axis for spectacle-free vision for distance. The evolution of topographers and optical biometers has made it quite achievable for us to aim the target. However, the result sometimes remains unpredictable. A big aspect of this depends on the preop axis marking for toric IOL alignment. Errors in axis marking have been reduced recently with the array of different toric markers in the market, but still we see postoperative refractive surprises due to faulty marking. In this video, we present a novel slit lamp-based toric marker innovation, STORM, which gives us a hands-free approach to a reliable and accurate axis marking on the cornea. The axis marker is a simple modification to our age-old marker, with the advantage of no touch and slit-lamp assistance, which will make it error free and easy to use. The present innovation answers the problem statement of stable, economical, and accurate marking solution. Many a times, hand-holding devices create inaccurate and stressed condition while marking the cornea before corneal surgery. The invention can be used for marking of accurate and easy astigmatic axis of a toric IOL preoperatively, that is, before the surgery. If the appropriate device is used to mark the cornea, it would impact the outcome of surgery. This device also makes the patient and the surgeon comfortable to mark the cornea with accuracy and without hesitation. https://youtu.be/4MVM7HRwz70.

Background
Toric Intraocular lenses (IOLs) are supposed to be aligned at a particular axis for spectacle-free vision for distance. The evolution of topographers and optical biometers has made it quite achievable for us to aim the target. However, the result sometimes remains unpredictable. A big aspect of this depends on the preop axis marking for toric IOL alignment. Errors in axis marking have been reduced recently with the array of different toric markers in the market, but still we see postoperative refractive surprises due to faulty marking.
Purpose
In this video, we present a novel slit lamp-based toric marker innovation, STORM, which gives us a hands-free approach to a reliable and accurate axis marking on the cornea. The axis marker is a simple modification to our age-old marker, with the advantage of no touch and slit-lamp assistance, which will make it error free and easy to use.
Synopsis
The present innovation answers the problem statement of stable, economical, and accurate marking solution. Many a times, hand-holding devices create inaccurate and stressed condition while marking the cornea before corneal surgery.
Highlights
The invention can be used for marking of accurate and easy astigmatic axis of a toric IOL preoperatively, that is, before the surgery. If the appropriate device is used to mark the cornea, it would impact the outcome of surgery. This device also makes the patient and the surgeon comfortable to mark the cornea with accuracy and without hesitation.
