Abstract:
AlM: To compare the different formulas in intraocular lens(lOL) power calculations on high myopia after LASlK with cataract patients who received the phacoemulsification and intraocular lens implantation ( Phaco+lOL) .
METHODS:This was a retrospective study. Data from 102 eyes of 61 cataract patients with high myopia, who received Phaco+lOL after LASlK, were collected. Patients were divided into three groups by formulas in lOL 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 lOL power after LASlK were predicted and the accuracy of their predictions were compared 3mo after surgery. lt was an index of reliability of the formulas outcomes.
RESULTS:The ratios of equivalent lOL power after LASlK 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).
CONCLUSlON:The Haigis-L formula is more accurate than the SRK-T and Holladay formulas in predicting lOL power for cataract patients with high myopia after LASlK.
