Abstract:

 For long axial (high myopia) cataract eyes, the difference between real refraction and calculated refraction by commonly used formulas is relatively large, frequently leading to a  postoperative hyperopia. Several solutions have been suggested to address this problem, including using the specific IOL’s constants for long axial eyes, adjusting the axial lengths (ALs), and using new-generation formulas such as Holladay II, Olsen, and Barrett Universal II. These solutions have been reported to be superior to the standard formulas in terms of accuracy used in highly myopic eyes.   (Int Rev Ophthalmol,  2015,  39:     414-417)
