Abstract
Purpose: :
To determine the efficiency and safety of the Artisan lens for the correction of patients with high myopia.
Methods: :
In this prospective, longitudinal and descriptive study, an Artisan Lens was implanted in patients with high myopia and astigmatism < –3.00 D. Determination of dioptric power before surgery with Van der Heijde table was done. Uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA) (LogMar convertion), intraocular pressure, endothelial cell count (Topcon specular microscope SF2000, average of 3 images from the same central area), spherical equivalent and anterior chamber depth (Orbscan II), were studied preoperative and postoperatively at 6 and 12 months. Complications during the follow up period were reported. Analysis of variance between groups was done.
Results: :
A total of 44 cases were included. Twenty one cases were bilateral Average of age was 29 years old. All patients presented an average gain of 6 or more lines of UCVA and 1 line of BCVA (p < 0.01). No significant statistical difference in intraocular pressure were observed (p > 0.05). The spherical equivalent was reduced from –15.0 D to –1.5 D at year follow–up. The mean of anterior chamber depth was 3.13 mm preoperatively and 3.0 mm postoperatively. Preoperative endothelial cell density was 2,640 in average, 2,471 at 6 months and 2,227 at 12 months postoperative (p < 0.05 respectively) The complications were as follows: iris atrophy in 36% of cases, descentration in 6% y pos–traumatic sliding.
Conclusions: :
Artisan lens is an efficient method to correct high myopia, the diminish of endothelial cell density was statistically significant at one year of follow up.
