Abstract
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 toxicity on the cornea till the centre for autoalignmemt of the astigmatic axis on the cornea as displayed on the laser screen.With image guided technology, marking the horizontal and the 6 o clock limbus with the help of this marker under the microscope in lying down position, completely takes care of the cyclotorsion element for high toric numbers ensuring accurate axis alignment. Use of this toric marker resulted in accurate determination of the horizontal axis in patients with high astigmatism, resulting in fewer refractive surprises post operatively.
