Abstract Details

Purpose:

To compare ocular biometry and refractive results measured using conventional applanation ultrasonography and 3 different optical interferometries, Lenstar LS900Ⓡ, AL-ScanⓇ and OA-2000Ⓡ.

Setting:

Department of Ophthalmology and Visual Science, St. Paul’s Hospital, College of Medicine, The Catholic University of Korea2, Seoul, Korea

Methods:

The biometries of 31 cataractous eyes were measured using ultrasonography, Lenstar LS900Ⓡ, AL-ScanⓇ or OA-2000Ⓡ. The axial length, anterior chamber depth and keratometry were measured. The SRK/T formula was used to calculate intraocular lens power. Two months after cataract surgery, the refractive outcome was determined and results from the 4 different biometry methods were compared.

Results:

Axial lengths were 23.39 ± 0.95 mm, 23.42 ± 0.98 mm, 23.43 ± 0.98 mm and 23.44 ± 0.98 mm measured using ultrasonography, Lenstar LS900Ⓡ, AL-ScanⓇ and OA-2000Ⓡ, respectively with no statistically significant differences observed (p = 0.996). The anterior chamber depth and keratometry were 3.14 ± 0.41 mm, 3.10 ± 0.38 mm and 3.13 ± 0.39 mm (p = 0.936) and 44.41 ± 1.52 D, 44.54 ± 1.57 D and 44.44 ± 1.52 D (p = 0.937) for Lenstar LS900Ⓡ, AL-ScanⓇand OA-2000Ⓡ respectively. There were no statistically significant differences between the 3 optical devices. The mean absolute error of the 4 different devices were not statistically significant (p = 0.722).

Conclusions:

The ocular biometric measurements and prediction of postoperative refraction using ultrasonography, Lenstar LS900Ⓡ, AL-ScanⓇ or OA-2000Ⓡshowed no significant differences.
