Cases where cataract surgery with a femtosecond laser yields better results[5]

In cases of severe cataracts, it may be very difficult to perform a circular capsulorhexis of the lens capsule, which is necessary to create an entry point for the cataract surgery machine, because the light reflection does not occur. However, using femtosecond lasers allows for precise circular incisions without the need for light reflection. Additionally, in cases of very severe cataracts, the lens is hard, requiring a large amount of ultrasound energy for removal, which can negatively affect the cornea in such cases. However, by using femtosecond laser, the hard lens can be pre-cut into small pieces, allowing for lens removal with much less ultrasound, which can be especially helpful for patients with corneal diseases. Finally, using femtosecond laser makes it easier to determine the position of the artificial lens, so inserting premium intraocular lenses such as presbyopia-correcting multifocal intraocular lenses or astigmatism-correcting intraocular lenses, where precise positioning is especially important, can be beneficial.
