Marfan's Syndrome, consisting of bilateral dislocation of the lenses, arachnodactyly, cardiovascular abnormalities and dolichocephaly, presents the opportunity of refractively compensating for either the aphakic region of the pupillary aperture or the phakic portion through the dislocated lens. A teen age patient preferred his old spectacle correction in high myopic astigmatic form to all possible combinations of plus or minus spectacles and contact lenses, despite the theoretical and actual improvement in acuity and spatial localization. The only factor the resulted in his accepting the minus power contact lenses to correct the phakic portion of the pupilary aperture was his girl friend's insistence. The case is unique in that contact lenses were designed and worn well in powers ranging from + 14.00 D to −15.50 D by the same patient with no changes in physical design of the contact lenses except for the power.
