Rotational Stability of a New Posterior Chamber Toric Phakic Intraocular Lens.

ABSTRACT: Purpose:To evaluate the refractive results and rotational stability of Eyecryl toric phakic intraocular lens (pIOL). Methods:In this retrospective single-surgeon case series, manifest refraction, visual acuities, endothelial cell density (ECD), and pIOL rotation were evaluated over 6 months. Results:43 eyes from 23 patients were included. At 6 months, the SE was within ±0.50? D of emmetropia in 30 (70%) eyes and within ±1.00? D of emmetropia in 39 (91%) eyes. The efficacy and safety indices were 1.25?±?0.38 and 1.41?±?0.34, respectively. Mean ECD was 2719?±?296?cells/mm2 at the preoperative visit and 2779.42?±?422?cells/mm2 at the 6-month visit (p > 0.05). The mean value of absolute axis orientation error was 4.95?±?5.28°. Mean absolute change in axis orientation between visits was less than 3° for all visit intervals. Ninety percent or more of lenses were found to rotate 5° or less between all visit intervals. None of the patients experienced a vision-threatening complication, and no patient required secondary IOL repositioning. Conclusion:The pIOL appears to effectively reduce subjective manifest astigmatism and provide good visual acuity. Its position was found to be stable throughout the follow-up.
