Abstract
Purpose: To compare the accuracy of twenty intraocular lens (IOL) power calculation formulas in long eyes (26.00-29.99 mm) DESIGN: Retrospective accuracy and validity analysis METHODS: The data of patients who underwent uneventful phacoemulsification between August 2019 and July 2024 were reviewed. Pre-surgery IOL power was calculated using Haigis, Holladay 2, SRK/T and Barrett Universal II formulas. Three months after cataract surgery, refraction was measured. Post-surgery IOL power calculations were performed utilizing the following formulas: Castrop, EVO 2.0, Hill-RBF 3.0, Hoffer Q, Holladay 1, Hoffer QST, K6, Kane, Karmona, Ladas Super Formula AI (LSF AI), Naeser 2, Olsen (standalone), PEARL-DGS, T2, VRF and VRF-G. Root mean square absolute error (RMSAE), median absolute error (MedAE) and percentage of eyes with prediction error (PE) within ± 0.25 D, ± 0.50 D, ± 0.75 D and ± 1.00 were calculated.
Results: One hundred fifty-three eyes with axial length ranging between 26.00 mm and 29.47 mm, were studied. The SRK/T formula yielded the lowest RMSAE (0.349) with statistical superiority over Holladay 1 (0.519, P = 0.000), Olsen (standalone) (0.505, P = 0.000) and Hoffer Q (0.497, P = 0.000). In terms of MedAE, the lowest outcome was obtained by VRF-G (0.256) followed by Barrett Universal II, Hill-RBF 3.0 and LSF AI (all equally of 0.260). The highest percentage of eyes with prediction error within ± 0.50 D was achieved by SRK/T (84.97 %) statistically significant vs Holladay 1 (60.78 %), Hoffer Q (64.05 %) and Olsen(standalone) (68.63 %).
Conclusions: SRK/T has delivered highly accurate results in long eyes. Barrett Universal II, Hill-RBF 3.0, VRF-G and LSF AI are also very true.
期刊介绍：
The Asia-Pacific Journal of Ophthalmology, a bimonthly, peer-reviewed online scientific publication, is an official publication of the Asia-Pacific Academy of Ophthalmology (APAO), a supranational organization which is committed to research, training, learning, publication and knowledge and skill transfers in ophthalmology and visual sciences. The Asia-Pacific Journal of Ophthalmology welcomes review articles on currently hot topics, original, previously unpublished manuscripts describing clinical investigations, clinical observations and clinically relevant laboratory investigations, as well as .perspectives containing personal viewpoints on topics with broad interests. Editorials are published by invitation only. Case reports are generally not considered. The Asia-Pacific Journal of Ophthalmology covers 16 subspecialties and is freely circulated among individual members of the APAO’s member societies, which amounts to a potential readership of over 50,000.
