Abstract

To determine the actual axial length of the pseudophakic eye, we mea-sured the axial length using ultrasound before and after cataract surgery in 157 eyes of 97 patient.The measured axial length of the pseudophakic eye with silicone or acrylic intraocular lens was longer than the axial length measured before operation.There was linear correlation between axial length measured before and after operation in cases of PMMA, silicone, or acrylic intraocular lens.The axial length corrected with ultrasonic velocity and central thickness of the intraocular lens was approximate to the mea-sure before operaion.So, we concluded that axial length is not actually elongated after operation and the exact axial length may be obtained by correcting the measured axial length of the pseudophakic eye using ultra-sonic velocity and central thickness of the intraocular lens.

Key Words: Axial length;Central thickness of the intraocular lens;Ultrasonic velocity
