Accurate intraocular lens (IOL) power calculation in cataract surgery is very important to achieve the postoperative target refraction and high patient satisfaction, as patients’ expectations have been progressively increased.
Therefore, there has been an ongoing effort to predict the postoperative refractive outcome with accuracy and consistency. The refractive power of the human eye depends on the power of the cornea, the lens and the axial length (AL) of the eye and the axial position of the lens. The aforementioned factors are crucial to obtain the optimal postoperative refractive results.
It has been considered that IOL calculation formulas were more accurate for eyes with normal AL, but do not have the same level of postoperative refraction outcome for eyes with short AL and high AL. In light of the above, the purpose of our study was to evaluate and compare the predictive capacity of IOL power calculation formulas (SRK/T and Holladay in high AXL > 24.0mm)
