Phacoemulsificatıon and Intraocular Lens Implantation in Eyes with Long Axial Length
Annals of Ophthalmology, 2007We evaluated the results of phacoemulsification and intraocular lens implantation in 414 eyes with long axial length and classified them according to axial length (AL): Group A: AL: 25-28 mm, Group B: AL >28 mm. Intraoperative maneuvers, pre- and postoperative photocoagulation for predisposing retinal lesions and retinal detachment rates were ...

Correlation between eye axial length and corneal biometric parameters
Acta Ophthalmologica, 2010Abstract Purpose To investigate the correlation between the eye axial length and the corneal biometric parameters in a normal population. Methods We prospectively recorded axial length, ultrasonic pachymetry and corneal topography (Orbscan) of 250 healthy eyes (excluding high myopia) of 125 patients aged from 10 to 80 years. Three refractive subgroups (

Axial Length Measurement in Silicone-Oil-Treated Eyes
1995Axial length measurement for IOL power calculation is troublesomein silicone-oil injected eyes. The sound velocity of silicone-oil is necessaryfor axial length calculation in such eyes. Using a specially designedchamber the velocity of our clinically used silicone-oil at 38 °C was measuredto be 964 m/s.

Axial length and radius of rotation of the eye
Clinical and Experimental Optometry, 1990Notwithstanding the advent of ultrasound, there remain clinical difficulties in measuring axial length. One alternative method, using a radius of rotation (r) of the eye, has been proposed. However, there are deficiencies in the technique and doubt concerning its reliability.

Relationship between axial length and chromatic refraction of the eye
Ophthalmic and Physiological Optics, 1992A new mathematical expression is derived to provide an estimate, ax, of the axial length of the human schematic eye. Approximations in the expression are made after considering effects in the Gullstrand‐Emsley schematic eye. Parameters required to solve the expression are, for two wavelengths, the refractive indices of the humours, the focal power of ...

[The measurement of eye axial length by ultrasound].
Zhongguo yi liao qi xie za zhi = Chinese journal of medical instrumentation, 1998Ultrasonic biometer is the best method of eye axial length measurement now. In this paper, our biometric method is introduced. It can measure the anterior chamber depth, lens thickness, vitreous length and axial length automatically, which are important to intraocular implant (IOL).

Calculating axial length in the aphakic and the pseudophakic eye
Journal of Cataract and Refractive Surgery, 1988The axial length of 149 eyes (84 pseudophakic and 65 aphakic) was calculated by refractive means and compared with the axial length determined by ultrasound. The mean error (+/- SD) between the measured and the calculated axial length (measured minus calculated) was 0.02 mm (+/- 0.51) and 0.13 mm (+/- 0.54) for the aphakic and the pseudophakic eyes ...

Plasminogen Activator: Influence on Axial Length in Chick Eye
1998Transforming growth factor β (TGF-β) is thought to be a regulator of the development of form-deprivation myopia (FDM) in the chick. We investigated the change in axial length when TGF-β was activated by plasminogen activator, which is a major biologic activator of TGF-β.
