Retrospective review identified 29 patients (12 men, 17 women; 58 eyes) who underwent uncomplicated cataract surgery by one surgeon (ODS) using the same intraocular lens implant (Alcon SA), and who had pre-operative biometry using the Zeiss IOLMaster (IOLM). Axial length, keratometry, and predicted refractive outcomes (Holladay I and SRK/T) were recorded. Pre- and post-operative manifest spherical refractive equivalent (MSRE) were collected. The differences between the post-operative and predicted MSRE (Refractive Outcome) were evaluated for the first and second eyes.
Mean patient age was 71yrs (range 50-92). Pre-operative MRSE, axial length, keratometry, predicted MSRE and post-operative MSRE are shown in Table 1. Post-operative MSRE was obtained at 61.2 +/- 60.9 days in the first eye, and at 20.9+/-18.4 days in the second. Refractive Outcomes are shown in Table 2. A statistically significant correlation between the Refractive Outcomes for the first eye compared to the second eye was not found using either Holladay I (p=0.18) or SRK/T (p=0.40).
Actual refractive results are very close to predicted IOLM targets for both the first and second eyes of patients undergoing cataract surgery. We were not able to identify a correlation between the Refractive Outcomes in the first and second eye.
