Abstract

PURPOSE
To evaluate the correlation between the conventional method and the clinical history method those determine intraocular lens (IOL) power for cataract surgery in eyes with prior laser in situ keratomileusis (LASIK) in the absence of pre-LASIK data. METHODS: The medical records of 200 eyes in 100 patients who had been treated with LASIK for myopia and were followed up for more than 6 months were reviewed. The IOL powers by conventional method using post-LASIK keratometric value and by clinical history method were compared. RESULTS: The mean values of IOL powers by conventional method, and by clinical history method were +20.00+/-1.48D (+13.74~+23.23D) and +20.79+/-1.28D (+17.27~+24.32D), respectively. The following equation describes the regular relationship between the two METHODS: IOL(CHM) (clinical history method)=0.708*IOL(CM) (conventional method) +6.624 (r=0.816, p<.01). CONCLUSIONS: This equation may offer more accurate IOL power for cataract surgery in eyes with prior LASIK surgery in the absence of pre-LASIK data.
