Stereopsis and aniseikonia in uniocular aphakia.
نویسنده
چکیده
Uniocular aphakia in the adult when corrected with a contact lens is in most patients no obstacle to binocular function. The long-term result is a balance between binocular function obtained and the comfort of the contact lens, and in this respect the advent of the soft lens, and especially the continuous-wear lens, appears to be most promising.

The use of intraocular lenses in the correction of aphakia was first described by H. Ridley (I 951), and subsequently numerous designs have been described and their use enthusiastically recommended. The problems ofspectacle correction for aphakia are well known and have been described in detail (Editorial, I952; Linksz, I965), and many ophthalmic surgeons are only too familiar with the patient ...

This paper continues the assessment of the long-term merits and problems of intraocular acrylic lenses which was started by a consideration of the value of the Binkhorst iris clip lens in aphakia by Pearce (I972). The reduced degree of aniseikonia and the better opportunity for binocular vision when uniocular aphakia is corrected by an intraocular lens implant was emphasized by Girard, Friedman...
متن کاملDeficiency of adaptive control of the binocular coordination of saccades in strabismus
Disconjugate (different in the two eyes) oculomotor adaptation is driven by the need to maintain binocular vision. Since binocular vision is deficient in strabismus, we wondered whether oculomotor disconjugate adaptive capabilities are deficient in such subjects. We studied eight adult subjects with constant, long-standing convergent strabismus of variable angles (4-30 prism D). No subject had ...

UNIOCULAR aphakia is a condition of artificial anisometropia which very often causes great annoyance to the sufferer, who finds the aphakic eye of little use if the other eye is normal, and often complains of lack of binocular function and difficulty in judging distances, especially at close range. If contact lenses have been tried with unsatisfactoryresults, it seems justifiable especially in ...

THE problem of uniocular catcaract witlh good visual acuity in the other eye is an old, but by no means a solved, problem. The established views still upheld by many oplhthalmologists, that such a cataract is best left alone, is based on the observation that the optical correction of unilateral aphakia is not satisfactory, a-s diplopia and general discomfort are exl)erienced. Furthermilore, the...
