  • Page 9: Before Use

    The NIDEK Multicolor Laser Photocoagulator MC-500 is a laser photocoagulator for ophthalmology with the light source of wavelengths 647, 577, and 532 nm. As the conventional laser photocoagulators, the MC-500 can be used for retinal photocoagulation for treatment of ocular fundus diseases like diabetic retinopathy, age-related macular degeneration, retin- opathy of prematurity, and retinal detachment, or for laser iridotomy and laser trabeculoplasty for treat- ment of glaucoma.

  • Page 10: Principles

    The MC-500 splits the pumped laser beam into the aiming and treatment beams to control them sepa- rately. Then the aiming and treatment beams are combined and lead to the fiber optic cable. The out- put end of the fiber optic cable is connected to the delivery unit.

  • Page 11: Classifications

    Form of protection method against electric shock: Class I The MC-500 is classified as a Class I device in which protection against electric shock and does not rely on basic insulation only, but which includes additional safety grounding of accessible conductive parts in the fixed wiring in such a way that accessible conductive parts cannot become live in the event of a failure of the basic insulation.

  • Page 71: Photocoagulation

    1968, and the laser photocoagulation has been applied to various patholo- gies. The MC-500 is the instrument that the wavelength can be selected for laser photocoagulation in ophthalmol- ogy: red (wavelength: 647 nm), yellow (wavelength: 577 nm), and green (wavelength: 532 nm). Laser pho- tocoagulation by using the MC-500 can be applied to treat the following pathologies: •Diabetic retinopathy...

  • Page 72: Characteristics Of Wavelength

    PHOTOCOAGULATION Cautions in Ophthalmology 4.1.2 Characteristics of wavelength (a) Red wavelength • Highly absorbed by melanin in retinal pigment epithelium or choroid. • Lowly absorbed by hemoglobin. Laser beam is rarely scattered in intraocular transit. • Negligibly absorbed by xanthophyll in macula. This minimizes undesired inner retinal damage during macular photocoagulation.

  • Page 73: Cautions In Photocoagulation

    PHOTOCOAGULATION Cautions in Ophthalmology If the procedures in photocoagulation are improper, desired effect can not be obtained or it may dam- age the tissue. This occurs when the tissue to be treated can not be observed clearly. Corneal opaci- ties, opaque ocular media, vitreous hemorrhage can interfere with the laser surgeon’s view of appropriate target structures.

  • Page 74: Contraindications For Photocoagulation

    PHOTOCOAGULATION Cautions in Ophthalmology 4.2.2 Contraindications for photocoagulation The region which should not be photocoagulated and the reason are described below. 1. Fovea centralis Fovea centralis should not be photocoagulated by using any wavelength because it may cause a visual loss due to the degeneration of optic cell, or cause a formation of coincident scotoma at the photocoagulated tissue.

  • Page 75: Treatment Parameters In Ophthalmology

    PHOTOCOAGULATION Treatment Parameters in Ophthalmology Treatment Parameters in Ophthalmology Ophthalmic problems are effectively treated with red, yellow or green laser photocoagulation wave- lengths. Treatment parameters depend on a variety of factors including the type of tissue to be treated, the intensity of the lesion desired, and the individual pigmentation of tissue targets. Laser power should initially be set at a low level and then be increased gradually until the desired tissue effect is obtained.
