Summary: Purpose: Comparing intraocular lens power calculation formulas’ accuracy for eyeballs smaller than 22.0 mm.
Material and methods: 89 patients with eyeball axial length between 20.33 mm and 21.99 mm were examined. Before cataract surgeries, each patient had their intraocular lens power calculated according to six formulas (SRK II, SRK/T, Binkhorst, Hoffer Q, Holladay 1, Haigis). During the cataract surgeries, Hoffer Q implant power was inoculated. Visual acuity was examined on Snellen chart thirty days after the cataract surgeries.
Results: 84 patients (94.4%) after cataract surgery had uncorrected visual acuity 1.0 on Snellen chart. According to the other formulas, uncorrected visual acuity 1.0 on Snellen chart would be achieved in the following cases: Holladay 1: 79 patients (88.7%), Binkhorst: 76 patients (85.4%), SRK/T: 61 patients (68.5%), SRK II: 45 patients (50.6%), Haigis: 4 patients (4.8%).
Conclusions:
1. Hoffer Q formula is recommended for intraocular lens power calculation for eyeballs with an axial length smaller than 22.0 mm.
2. Holladay 1 and Binkhorst formulas seem to be satisfactory for these cases.
