Soft contact lenses in cases of aphakia.

چکیده
The use of hydrophilic acrylates (POIYHEMA) in the composition of contact lenses was first described by Wichterle and Lim (I960). The development of a spun cast lens has taken several years. The basic technique by Wichterle has now been extended by the manufacturers, Bausch and Lomb. Whilst the low minus powers are available in more than one back curve fitting, the high minus and aphakic series have one basic fitting for each power. The aphakic lenses have reduced front optics to give a central thickness of 0-40 mm. (approx.) a peripheral thickness ofO 14 mm., and an overall size of 13 50 mm. This study was undertaken to evaluate the series of lenses for use in cases of aphakia.

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...

We prospectively studied for three years the optical correction by contact lenses of 83 aphakic infants (141 eyes) who generally also had systemic and other ocular anomalies: 85% of the patients tolerated the lens wear for the whole study period. Complications occurred in 46 eyes and led to cessation of lens wear in two cases. Ten patients abandoned the lenses for other reasons. Thirty-four eye...

The authors have designed and produced extended-wear contact lenses for rhesus monkeys. High-plus lenses to correct neonatal aphakia as well as lenses dyed black for use as occluders to treat amblyopia have been evaluated. Four infant monkeys fitted with soft lenses have successfully worn these extended-wear lenses almost continuously throughout their first year of life. These experiments demon...
