Overview
Purpose:
To compare best corrected visual acuity and contrast sensitivity in patients with aspheric and spheric intraocular lens (IOL) after uncomplicated cataract surgery in photopic and mesopic conditions.
Methods:
38 eyes after uncomplicated cataract surgery were divided in two groups. A (18 eyes, average 69,5 ± 6,89 years, spheric IOLs Softec 1, Lenstec, Inc. USA); B (20 eyes, average 69,47 ± 9,44 years, aspheric IOLs Softec HD, Lenstec, Inc. USA). Follow up 3.–5. day and 4.–5. week postoperatively.
Results:
Best corrected visual acuity in group A was 20/23, in group B was 20/22. Contrast sensitivity in photopic conditions between group A and B were nonsignificant. Contrast sensitivity in scotopic conditions was in group B (aspheric IOLs) significant in comparison to group A (spheric IOLs).
Conclusions:
Aspheric IOLs in scotopic light conditions provide patients with significant better contrast sensitivity than in patients with spheric IOLs.
Key words:
aspheric, spheric, contrast sensitivity, photopic light conditions, scotopic light conditions
