| Abstract |
|
The purpose of this study is to assess the accuracy of IOL power calculations using clinical history method in patients who undergo cataract surgery after previous PRK, RK, or LASIK.Five eyes of 3 patients who had previous PRK, RK, or LASIK underwent phacoemulsifications with IOL implantation.We calculated IOL power for target refractive error using clinical history method.We compared postoperative refractive error to target refractive error at 3 months after cataract surgery.In the first case (RK (od)& PRK (os)), there was 3.50 diopter undercorrection on the right eye and IOL was exchanged.And target refractive error was achieved on the left eye.In the second case (LASIK patient)there was 1.00 diopter undercorrection.In the third case (PRK (ou)), right eye achieved 0.75 diopter undercorrection and left eye achieved 0.50 diopter overcorrection.The types of cataract were nuclear sclerotic in 3 cases and anterior subcapsular in 2 cases.To determine the exact IOL power after refractive surgery, using clinical history method would be good alternative in these patients. |
