Abstract

PURPOSE: To compare ocular higher-order aberrations (HOAs) in eyes with aspheric intraocular lenses (IOL) and in phakic eyes.
SETTING: Department of Ophthalmology, Military Health Service Institute, Warsaw, Poland.
METHODS: Higher-order aberrations with a 5.0 mm pupil and best spectacle-corrected visual acuity (BSCVA) were analyzed in a young phakic group (age 20 to 40 years), older phakic group (age 40 to 60 years), and a pseudophakic group (age 62 to 84 years; SN60WF aspheric IOL).
RESULTS: The mean coma was 0.13 microm+/-0.07 (SD) in the younger phakic group, 0.18+/-0.08 microm in the older phakic group, and 0.16+/-0.08 microm in the pseudophakic group; the difference between the 2 phakic groups was statistically significant (P< .005). The mean spherical aberration was 0.07+/-0.05 microm, 0.11+/-0.05 microm, and 0.06+/-0.04 microm, respectively; the only statistically significant difference was between the 2 phakic groups (P< .005). The mean HOA value was 0.54+/-0.18 microm, 0.76+/-0.12 microm, and 0.92+/-0.31 microm, respectively; the difference was statistically significant between the 2 phakic groups or between the younger phakic group and the pseudophakic group (both P< .005). There were no statistically significant differences in BSCVA between the 3 groups.
CONCLUSIONS: Spherical and coma aberrations were similar in eyes with an aspheric IOL and younger phakic eyes, although HOAs were higher in pseudophakic eyes. There were no differences between pseudophakic eyes and older phakic eyes in coma and HOA, although pseudophakic eyes had lower spherical aberration.
