The TK might also improve the refractive prediction in highly myopic eyes. Traditional IOL power calculation formulas based on normal eyes might generate unexpected errors for highly myopic eyes [8]. Two vergence formulas, the SRK/T and Haigis, have shown acceptable outcomes in highly myopic eyes ...
However, lens calculations are not perfect. Residual postoperative refractive error can be common, especially in patients who undergone refractive corneal surgery before and are now developing cataracts3,4,5,6. In spite of a good many of methods for IOL power calculation, the postoperative refractive...
To develop a novel machine learning-based intraocular lens (IOL) power calculation formula for highly myopic eyes. A total of 1828 eyes (from 1828 highly myopic patients) undergoing cataract surgery in our hospital were used as the internal dataset, and
