Aphakic ultrasonographic refraction in adults. Comparison with retinoscopy and subjective refraction.
A simple method of aphakic refraction using ultrasonographic axial length measurement and keratometry was tried on 97 eyes of adult aphakic patients. The refractive errors determined by this method and by retinoscopy were compared to the subjective refraction of the same eyes. The ultrasonographically determined refractive errors were significantly nearer the subjective refraction than were the retinoscopically determined refractive errors.
