[2 years experience in the treatment of myopia with photokeratectomy].

The results of the PRK treatment started on june 91 on 30 myopic eyes between -4 and -16 D with the Meditec Mel 60 show: a tendency to overcorrection in high myopia, undercorrection in low myopia, a tendency to regression in high myopia of about 3 D and no regression in low myopia. A slight decentration of the treated area is common but the vision is not affected. The haze is often visible but never dramatic and decreases significantly with time. Most of the patients are fully satisfied in the visual rehabilitation if they do not expected emmetropia.

[Effect of grid orientation of interference patterns on contrast sensitivity in white and colored light].

The contrast sensitivity of 34 healthy eyes and 32 suspected of having glaucoma was measured at 3, 6, 12, 18, and 24 cycles/degree with vertical, oblique and horizontal interference fringes. These were produced by the Haag-Streit Visometer as modified by Lotmar with an additional device for contrast variation. At all frequencies, maximum contrast sensitivities were found for vertical gratings. However, there was a tendency for oblique gratings to show relatively low contrast sensitivities at high spatial frequencies; the same applied for horizontal gratings at low frequencies. The effect of stimulus orientation was similar for white, red, green and blue light.
