Purpose:
|
To compare postoperative refractive error in the second eye cataract surgery in 3 groups based on different intraocular lens (IOL) power modifications according to the residual refractive error of the first eye.
|
|
Methods:
|
Patients who underwent the first-eye cataract operation 1 to 3 months earlier and were scheduled for cataract surgery in the second eye were entered this study. If the absolute postoperative SE of the first eye was less than 0.5 D, the patient was excluded. Other patients were assigned to 3 groups and we made different modifications to the calculated IOL power of the second eye according to the residual refractive error of the first eye. The second-eye refractive error was evaluated 8 weeks after surgery and was compared in three groups.
|
|
Results:
|
The average of the absolute values of the residual postoperative refractive error of the second eye were 0.26 ± 0.2 diopters (D) in 100% adjusted group; 0.33 ± 0.25 diopters (D) in 50% adjusted group; 0.57 ± 0.27 diopters (D) in nonadjusted group.(P<0.05) for the unadjusted group
|
|
Conclusion:
|
In bilateral cataract surgery; accounting for 50% of the residual refractive error of the first eye in IOL calculation of the second eye can improve refractive results of the second eye.
