Abstract

Purpose: Different femto lasers for lenticule based surgeries have different camera settings to show the image of the applanated area on the screen. The purpose of inventing this instrument is to be able to mark the toricity on the cornea till the centre, autoalignment of the astigmatic axis on the cornea as displayed on the laser screen.
Setting: With image guided technology, marking the horizontal and the 6 o clock limbus with the help of this marker was done
Methods: 50 patients were selected with moderate myopia and myopic astigmatism. Thereafter the marks were examined so that extension upto the pupillary margin was clearly visible. Lenticule extraction was performed
Results: Use of this toric marker resulted in accurate determination of the horizontal axis in patients with high astigmatism.
Conclusions: This toric marker helps to determine true axis of astigmatism and accurate marking to allow perfect auto alignment of the laser axis.
