Abstract

Abstract: : Purpose:To investigate the changes of higher order aberrations (HOA) and contrast sensitivity, and their correlation after implantation of Artisan phakic intraocular lens (IOL). Methods: Twelve eyes of 10 patients were examined preoperatively and 1 month after implantation of Artisan phakic IOL. The mean preoperative spherical equivalent was –11.40±1.15D (–9.75 to –13.25D). The diameter of the IOL optic was 6mm and the lens was inserted through a sclera tunnel incision at 12 o’clock. The contrast sensitivity was tested and the root mean square (RMS) wavefront error was computed for all aberrations of the third to sixth order for pupil diameter of 5.5mm. Results: On average, RMS changed by 0.216±0.194µm (p<0.05). Z3,–1 (Coma) changed by 0.1352±0.1155µm (p<0.05) and Z3,–3 (Trefoil) changed by 0.1462±0.190µm (p<0.05). The logMAR of contrast sensitivity was decreased at all spatial frequencies (p<0.005). The changes in the logMAR by implantation of Artisan phakic intraocular lens showed significant correlations with changes in RMS (Pearson correlation coefficient r=–0.655, p=0.021). Conclusions: After implantation of Artisan phakic IOL, HOA increased slightly, especially coma and trefoil. The increases in the postoperative HOA of the eyes was correlated with the decline of contrast sensitivity function after implantation of Artisan phakic IOL.
