What is the LensAR™ Laser System?
The LensAR™ laser system is an ophthalmic surgical laser designed to perform portions of a cataract operation. It is a mode-locked Nd: YVO4 laser which generates a high frequency series of low energy femtosecond pulses at a wavelength of 1064 nm. The laser has been cleared by the FDA for performing the anterior capsulotomy and phacofragmentation of the lens during cataract surgery. The laser is delivered in the eye through a single-use patient interface designed to match the refractive index of the cornea to optimize laser accuracy. The proprietary 3D-CSI™ imaging and biometry system is designed to image and analyze the anatomy through all levels of cataracts to improve results.
Performing the Anterior Capsulotomy with the LensAR™ Laser System
The LensAR™ laser system is designed to cut the anterior capsule of the lens with minimal collateral damage. The capsule surrounds the lens inside the eye which as we age becomes cloudy (cataract). The capsule is opened in order to remove the cloudy lens material. The precision capsulotomy is cut by computer-controlled scanning of the position of the laser beam focus in three dimensions inside the eye. The size, shaped, and location is controlled by the computer in the laser system. This allows for consistent results of performing the anterior capsulotomy.
Phacofragmentation of the Lens with the LensAR™ Laser System
Normally the nucleus of the lens is emulsified or dissolved using an ultrasonic needle or tube inserted into the lens. The liquefied material is aspirated from the eye. The LensAR™ laser performs phacofragmentation of the lens similar to the ultrasound machines used in cataract surgery. The LensAR™ laser system delivers femtosecond laser pulses that produce a planned pattern of photodisruption precisely in the lens.
Benefits of the LensAR™ for Cataract Surgery
The anterior capsulotomy can be performed in a precise manner which helps with consistent results with the outcomes from cataract surgery. The exact size and shape can be determined as well as a well centered capsulotomy.
Since the femtosecond pulses are delivered through the cornea, the LensAR™ laser performs the phacofragmentation inside the eye without the mechanical effects and ultrasonic shockwaves transmitted to the ocular tissues inside the eye by the traditional ultrasonic hand pieces. Less ultrasound means better outcomes in cataract surgery.
The LensAR™ provides an exciting new technique for cataract surgery which is going to provide improved and more consistent results with fewer complications for an operation that is already one of the most successful surgeries.
