The ophthalmologist programs a specially designed treatment plan for your ocular condition, including one or more of the following:
– Corneal incisions: If the ophthalmologist deems it necessary and safe, the laser can create the main incision and the relaxing limbal incisions with micron-scale precision in terms of length and depth.
– Anterior capsulotomy: The quality of the opening in the anterior lens capsule is key to the proper positioning of the intraocular lens inside the capsular bag and, ultimately, to the precision of the visual correction. The laser makes a perfectly round opening of a predetermined diameter centred on the capsular bag. This fosters uniform recovery of the anterior surface of the intraocular lens and more predictable positioning than manual capsulorhexis.
– Lens fragmentation: If the ophthalmologist deems it necessary and safe, the laser can cut the lens into small pieces before phacoemulsification. This reduces ultrasound time before lens aspiration, especially in the case of a mature cataract.
These steps take only a few seconds and are performed with the precision and repeatability of the femtosecond laser. The Catalys® uses a 3D imaging system to map the surface of the eye during surgery (OCT live), identify safety parameters and ensure the continuous guidance of the laser during the procedure.
