Purpose:
|
To evaluate the results of AcrysofToric IOL in cataract surgery in keratoconus
|
|
Methods:
|
This case series evaluated 23 keratoconic eyes who received cataract surgery with Toric IOL. Keratometry was performed with a manual keratometer, ،Topography, and Pentacam in all patients.
|
|
Results:
|
Three months post-operation, the mean UCVA in mild and moderate KCN was significantly better. The pre-operative UCVA (P<0.01) decreased from 1.3 to 0.38 LogMAR in severe keratoconus. The mean BCVA also increased significantly post-operation (P<0.01). The highest BCVA improvement was observed in moderate KCN. The mean spherical equivalent showed a substantial decrease in all groups and the highest astigmatism correction was observed in mild and moderate KCN. The mean IOL rotation was 2.50±1.18, 2.50±1.51, and 2.67±1.15º in mild, moderate, and severe KCN, respectively. The lowest mean absolute error was obtained with topography and the SRKT equation in mild and moderate keratoconus. In severe KCN, mean absolute error is lowest with Topography and manual keratometry and SRKT and SRK II equations.

|
Conclusion:
|
Toric IOL resulted in a desirable vision and refraction in cataract surgery in non-progressive KCN. Topography and the SRKT equation resulted in minimal error in determining the IOL power.
