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