Since the use of femtosecond laser (FSL) in refractive surgery, it has been expanded to other corneal surgeries and most recently has been applied to cataract surgery. The FSL can create clear corneal incisions and limbus relaxing incisions in any space of different shapes, at a desired depth. This has started the application of the technology in the lens: after a clear image is taken of the lens through a previously dilated pupil, circular capsulotomy is done, with precision in shape and diameter, and then photofragmentation of the nucleus is done, without the risk of damaging the posterior capsule, because it is well visualized, to achieve the aspiration of the nuclear material in lower even without applying phaco energy. In summary, FSL is now used at the level of the lens, with the potentiality for very precise circular and adjustable diameter capsulotomies, and the fragmentation of the nuclear material, allowing the less use of forcep and phaco machine.
