A low-cost contact lens for green-only argon-laser photocoagulation.
Filtration of argon laser light to eliminate the blue wavelengths and create a green-only light may be clinically useful in treating macular lesions. To that end, an inexpensive, easy method of modifying a posterior pole contact lens for use with any ophthalmic argon laser to allow only green, not blue, laser light to be used for macular photocoagulation is described.
