Femtosecond Laser Cataract Surgery and Intraocular Lens

Feature Summary

FLACS provides precise and reproducible key steps in cataract surgery, including corneal incisions, capsulotomy and lens fragmentation. Besides, laser pretreatment could reduce phacoemulsification ultrasound energy.




According to the World Health Organization (WHO), cataract is the leading cause of blindness and visual impairment throughout the world. A cataract is opacity of the lens in the eye which causes vision impairment. It probably also leads to altered contrast sensitivity, glare, myopic shift or monocular diplopia.



Cataract surgery

Cataract removal is the standard surgical treatment to improve one’s vision. The conventional cataract surgery is phacoemulsification cataract surgery. In recent years, femtosecond laser-assisted cataract surgery (FLACS) is developed to assist cataract surgery. After cataract is removal, an intraocular lens will be implanted to provide optical power of an eye.



Patients will be sent to a laser room. After proper docking, spectral-domain optical coherence tomography is used to image and map the treatment plan. Laser is applied to perform wound incision (optional), capsulotomy and lens fragmentation. Then, patients will be sent to another operative room for phacoemulsification cataract surgery. Under the operative microscope, the primary incision will be created or opened, and an ophthalmic viscosurgical devise (OVD) should be injected as usual into anterior chamber. Anterior capsulorhexis will be checked and the anterior capsule will be removed. After hydrodissection, phacoemulsification, an intraocular lens will be implanted. At the end of surgery, the corneal wounds will be sealed by stromal hydration or sutures.
