Scleral contact lens wear in unilateral aphakia.

Scleral contact lens wear in unilateral aphakia.

Contact lens in unilateral aphakia.

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...

Unilateral Aphakia and Contact Lenses*

The size of the retinal image in the corrected aphakic eye is some 24% larger than the image before removal of the crystalline Len's. This large differential makes binocular vision impossible in individuals with unilateral aphakia corrected by spectacle lenses. A similar calculation, but with a contact lens correction, reduces this figure to about 8% (Dawson, 1962) . Theoretically, intraocular ...

Contact lens induced keratitis associated with contact lens wear.

PURPOSE To evaluate clinical characteristics, risk factors, management and outcome of contact lens induced keratitis (CLIK) associated with contact lens wear. METHODS The study comprised all consecutive patients presenting with contact lens related presumed microbial keratitis during a 12-month period at our department. Detailed demographic data, type of contact lens, duration of lens wear, w...

Tear calcium levels and contact lens wear.

Hydrophilic contact lens spoliation can be associated with the deposition of calcium salts. The relationship between the concentration of calcium in tear fluid and contact lens use has been studied in healthy volunteers and in patients using various forms of hard and soft contact lenses, tear samples being collected with Schirmer strips and with lenses in situ. Methods are suggested for correct...
