Evaluation of Improving in Forward Light Scatter and Ocular Scatter Index With Double-Pass Wavefront After Dysfunctional Lens Replacement
Purpose
To evaluate the change in forward light scatter in terms of the ocular scatter index (OSI) with double pass wavefront technology in eyes with dysfunctional lens syndrome after dysfunctional lens replacement.
Methods
Eyes with dysfunctional lens syndrome undergoing dysfunctional lens replacement were evaluated retrospectively. Double pass wavefront technology was used to measure the ocular scatter index (OSI) both preoperatively and postoperatively. Aspheric monofocal and diffractive multifocal eyes were divided into groups were compared preoperative to postoperative. Fifty eyes were evaluated and will be reported, interim analysis is presented herein.
Results
The mean preoperative OSI in the mono-focal group (n=8) was 1.729+/- 1.282 and .988+/- .053 after lens replacement (p=0.01). The mean preoperative OSI in the multifocal group (n=8) was 1.157+/-1.403 and 2.057+/-1.340 after dysfunctional lens replacement (p<0.01).
Conclusion
Dysfunctional lens replacement resulted in statistically significant improvement in forward light scatter as measured by the ocular light scatter index when aspheric monofocal IOLs were implanted. Implantation of diffractive multifocal IOLs resulted in an increase in ocular scatter index after dysfunctional lens replacement.
