Objective. To evaluate the postoperative visual quality of cataract patients with extreme myopia after implantation of aspheric\nintraocular lenses (IOLs). Methods. Thirty-three eyes were enrolled in this prospectivestudy. Eighteen eyes with an axial length\nlonger than 28 mm were included in the extreme myopia group, and the other 15 eyes were included in the nonextreme myopia\ngroup. Phacoemulsification and aspheric IOL implantation were performed. Six months after cataract surgery, best-corrected visual\nacuity (BCVA), contrast sensitivity, and wavefront aberrations were measured, and subjective visual quality was assessed. Results.\nThe BCVA improved significantly after surgery for both groups, and patients in the nonextreme myopia group achieved better\npostoperative BCVA due to better retinal status of the eyes. The evaluation of contrast sensitivity without glare was the same in\nboth groups, whereas patients in the nonextreme myopia group performed better at intermediate spatial frequencies under glare\nconditions.The two groups did not show a significant difference in high-order aberrations.With regard to subjective visual quality,\nthe composite scores of both groups did not differ significantly. Conclusions. Aspheric IOLs provided good visual outcomes in\ncataract patients with extreme myopia. These patients should undergo careful evaluation to determine the maculopathy severity\nlevel before surgery.
