Abstract
We made the following experiments to compare and discuss the effects of laser iridotomy with various wavelength.
1) Laser photocoagulations were made on brown polyester sheets in piles with various wavelength of argon, krypton and dye lasers, and the transmission of the laser beams were evaluated.
2) Laser iridotomy was performed on rabbit's iris with various wavelength. Furthermore, laser iridotomy with dye laser (orange, 590nm) was performed on 9 eyes of 9 patients clinically.
Consequently, we have successfully performed laser iridotomy with dye laser (590nm) by fewer numbers of photocoagulations than argon laser.
