The spiral I.O.L. with a rectangular optic (6 mm x 4.8 mm) is particularly convenient for small incision surgery. A series of rhexis and a series of envelope technique were compared: centering was definitely better after rhexis. In secondary implantation after ICCE the spiral implant could be secured to the posterior face of the iris.
Thirteen patients with varying degrees of amblyopia were examined for perception of retinal rivalry with the use of the phase difference haploscope. Visual acuity was varied in the fixing eye by the addition of plus lenses, equalizing ocular dominance. Retinal rivalry could be detected over wide ranges of visual acuity disparity by amblyopic patients with visual acuity better than 20/50. Rivalry could not be detected, however, by patients with less than 20/50 visual acuity in their amblyopic eye.
