Purpose: We have devised a new method to mark the corneal axis of Toric IOL that is inexpensive and precise. Methods: In the office, a drop of ophthaine is placed on the eye and the patient is asked to place his/her chin on the chin-rest of the Yag laser. The Sunalp Yag laser lens is placed on the para limbal cornea with 90º lens corresponding to the 90º of the patient cornea. The Yag laser is focused at the mid cornea at 270º and a single laser pulse of 10 m-Joules is aimed at 270º with 1-3 pulses in line, 0.5 mm apart. The laser pulse marks the cornea with a small disruption and blanching of the stroma that remains visible for 48 hours or longer. The Sunalp Yag laser lens is a 1 cm, 12 diopter single-use, acrylic lens, which will be available in the near furure. Results: Presurgical corneal marking using the Sunalp Yag laser lens, a lens specially designed for the Yag laser, allows for accurate alignment of toric IOL during surgical implantation. The markings remain clearly visible throughout the procedure and for an additional 48 hours, giving ample time for pre op marking. Conclusion: To avoid the pitfalls of preoperative unreliable marking with an ink pen, we have devised a method to mark the cornea using the Yag Laser. Using the Sunalp Yag laser lens, precise, durable marking can be made without the use of expensive equipment.
