Abstract:
PURPOSE: To evaluate the Haigis-L method of IOL Master that does not require preoperative data for intraocular lens (IOL) power calculations and compare the results with other methods requiring preoperative data. METHODS: Fifty eyes of 25 patients who had undergone laser-assisted subepithelial keratectomy (LASEK) and were followed for 1 month or longer were selected for this study. IOL power was calculated by four different methods: clinical history method, Feiz-Mannis method, modified Masket method, and Haigis-L method. RESULTS: The mean calculated IOL powers showed the following results: clinical history method; 23.65D, Feiz-Mannis method; 24.45D, modified Masket method; 22.89D, and Haigis-L method; 23.80D. Each IOL power differed statistically from others (p=0.000). The difference between each method was analyzed by the Bonferroni test, with the Feiz-Mannis method showing the highest result and the modified Masket method, the lowest. The clinical history method and Haigis-L method presented similar results. CONCLUSIONS: For patients without data prior to corneal refractive surgery, the Haigis-L method is as accurate as the clinical history method. Therefore, comparatively accurate results can be produced in IOL power calculations using the Haigis-L method after corneal refractive surgery.
