The MEL 80 Excimer Laser System is indicated for use in primary Laser Assisted in situ Keratomileusis (LASIK) treatments for the reduction or elimination of - myopia of less than or equal to -7.0 D with or without refractive astigmatism of less than or equal to -3.0 D, with a Maximum MRSE of -7.0 D- naturally occurring hyperopia of less than or equal to +5.0 D with or without refractive astigmatism of greater than +0.5 D and less than or equal to +3.0 D, with a maximum MRSE of +5.0 D in patients who are 21 years of age or older with documentation of stable manifest refraction over the past year as demonstrated by Change in sphere and cylinder of 0.5 D.
A mains electricity (AC-powered) device assembly in which input energy is used to excite an excimer gas to emit a high-power laser beam intended for corneal ablation (i.e., photorefractive keratectomy) and other ophthalmologic procedures (e.g., surgical creation of a communication between the lacrimal sac and the nasal cavity). It includes a light source and controls/foot-switch, and is typically coupled to a biomicroscope slit lamp or to an indirect ophthalmoscope by a flexible fibreoptic cable. It does not include femtosecond pulsing or fundus imaging technology.
