Abstract:
PURPOSE: To evaluate the clinical results of 6 mm iris-fixated phakic intraocular lens (Artisan(R) lens) implantation in myopic patients. METHODS: Forty eyes of 23 myopic patients underwent 6-mm Artisan(R) phakic IOL implantation and were followed-up for over 6 months. We prospectively analyzed the efficacy, stability, predictability, change of astigmatism, endothelial cell count, pupil diameter, degree of decentration, subjective satisfaction and complications. RESULTS: The preoperative mean spherical equivalent was -9.46 D, and postoperative spherical equivalent was -0.70D at 1 month, -0.55D at 3 months, -0.54D at 6 months, -0.78D at 12 months and remained stable during the follow-up period. The preoperative mean astigmatism was -1.88D and postoperative astigmatism was -0.87D at 6 months. Postoperative uncorrected visual acuity (UCVA) was more than 0.8 in 85% of the eyes at 1 month, 91% at 3 months, 95% at 6 months, and 89% at 12 months. The spherical equivalent refraction after surgery was within 1.0D of emmetropia in 78% of eyes at 1 month, 80% at 3 months, 88% at 6 months, and 64% at 12 months. There was no significant decrease in the endothelial cell count during the follow-up period. Preoperative scotopic pupil diameters were significantly decreased at 1 month and the mean decentration of the lens was 0.38 mm. Patient satisfaction was generally high. Complications included the transient elevation of intraocular pressure in 1 eye, corneal edema in 4 eyes, iritis in 1 eye, traumatic dislocation in 1 eye and iris atrophy in 2 eyes. CONCLUSIONS: The 6-mm Artisan(R)phakic IOL implantation may be an effective surgical procedure for myopic patients who cannot undergo corneal refractive surgery, as it provided good visual results, predictability, patient satisfaction, and short-term safety.
