ABSTRACT
PURPOSE:
To examine the long-term refractive changes after stabilization of surgically induced changes (SICs) subsequent to cataract surgery.SETTING:
Private hospital.DESIGN:
Case-control study.METHODS:
Manifest refraction of 300 eyes of 300 patients who underwent phacoemulsification and 300 eyes of 300 age-matched and sex-matched patients without surgery was examined the day on which SICs stabilized (baseline) and ≥7 years postbaseline using an autorefractometer. Refraction was divided into 3 components spherical power (M), vertical/horizontal astigmatism (J0), and oblique astigmatism (J45) using power vector analysis, and the components were compared between the 2 timepoints and between groups.RESULTS:
Data of All 600 eyes were collected. In the surgery group, the mean M and J45 did not change significantly between baseline and ≥7 years postbaseline, but the J0 significantly decreased between the 2 timepoints (P < .001), indicating an against-the-rule (ATR) shift. In the nonsurgery group, the mean M significantly increased and J0 significantly decreased between the timepoints (P < .001), whereas J45 did not change significantly. The mean change in M between the 2 timepoints was significantly smaller in the surgery group (P < .001), whereas the changes in J0 and J45 did not differ significantly between the timepoints.CONCLUSIONS:
Spherical power did not change and refractive astigmatism significantly changed toward ATR astigmatism during the more than 7-year follow-up after stabilization of SICs in pseudophakic eyes, whereas hyperopic and ATR shifts occurred in phakic eyes, and the astigmatic changes were comparable between pseudophakic and phakic eyes.
