Abstract
AIM: To compare the different formulas in intraocular lens(IOL)power calculations on high myopia after LASIK with cataract patients who received the phacoemulsification and intraocular lens implantation(Phaco+IOL).

METHODS: This was a retrospective study. Data from 102 eyes of 61 cataract patients with high myopia, who received Phaco+IOL after LASIK, were collected. Patients were divided into three groups by formulas in IOL power calculations before surgery: Holladay group(11 cases, 21 eyes), Haigis-L group(30 cases, 47 eyes)and SRK-T group(20 cases, 34 eyes). The ratios of equivalent IOL power after LASIK were predicted and the accuracy of their predictions were compared 3mo after surgery. It was an index of reliability of the formulas outcomes.

RESULTS:The ratios of equivalent IOL power after LASIK using the Holladay, Haigis-L and SRK-T formulas were 0.86±0.41D, 0.43±0.30D and 1.27±0.58D, respectively. There was no significant difference between Holladay group and SRK-T group(t=-0.271, P=0.625>0.05). However, significant difference was found between Haigis-L group and Holladay group(t=2.249, P=0.047<0.05), Haigis-L group and SRK-T group(t=6.012, P=0.031<0.05).

CONCLUSION: The Haigis-L formula is more accurate than the SRK-T and Holladay formulas in predicting IOL power for cataract patients with high myopia after LASIK.
