Abstract
Purpose :
To examine the long-term changes of axial length in adults with an Artisan phakic intraocular lens for myopia and hyperopia using a longitudinal study design.
Methods :
Axial length is measured twice over time in 277 myopic (age 37.8 ± 10.3 years) and 50 hypermetropic eyes (age 41.0 ± 9.3 years). The difference in the two measurements is analyzed and plotted against time between the measurements. The preoperative spherical refraction ranged between -28.00 to +10.75 diopters.
Results :
Mean time interval between the two axial length measurements was 130 ± 42 months for myopic eyes and 138 ± 37 months for hypermetropic eyes. Myopic axial length significantly increases over time with 0.036 mm per year (p <0.001). Hyperopic axial length does not change significantly over time.
Conclusions :
Axial length in myopic adults after Artisan implantation increases over time with myopisation of ± 1 diopter after 10 years. The axial length in hypermetropic adults does not change over time.
