Florida Patent of the Month – November 2021

Cataract surgery is one of – if not the most – common ophthalmic surgical procedure. This surgery removes the defective lens, replacing it with an artificial or intraocular lens to restore optical clarity blocked by the defective lens. Recently, corneal incision has been performed with lasers over knives. After incision, the patient is moved below a separate machine – the phacoemulsification system – to extract the cataract. Lensar, Inc. has developed a combined laser and phacoemulsification system to improve the patient experience. Lensar is always “You-Centric”, always trying to improve patient experience and quality of care. The improvement to technology focuses on what is best for surgeons – which passes down to improved patient care.

Their combined machine uses a specific laser delivery system that works for multiple surgical procedures in the eye. It provides a sequence of laser pulses to photo disrupt or cut a specific tissue part inside the eye. It also integrates novel contact lens designs that work together with the different delivery system versions. The delivery system then scans the laser pulses to ensure it delivers a combination of full and particular circular cut patterns in the correct location. 

Their design improves the use of the scanning system and reduces the introduction of optical aberrations. This uses a simple and small main focusing lens rather than a large complex optical lens system to compensate. The lens is coupled to a microscope which is positioned to view the eye tissue to be treated, providing better vision and reduced complexity. Other improvements include reducing the overall footprint of the procedure by combining machines and minimizing patient relocation during the procedure.
